Intent

public class Intent
extends Object implements Parcelable, Cloneable

java.lang.Object
   ↳ android.content.Intent
Known Direct Subclasses


An intent is an abstract description of an operation to be performed. It can be used with startActivity to launch an Activity, broadcastIntent to send it to any interested BroadcastReceiver components, and startService(Intent) or bindService(Intent, ServiceConnection, int) to communicate with a background Service.

An Intent provides a facility for performing late runtime binding between the code in different applications. Its most significant use is in the launching of activities, where it can be thought of as the glue between activities. It is basically a passive data structure holding an abstract description of an action to be performed.

Developer Guides

For information about how to create and resolve intents, read the Intents and Intent Filters developer guide.

Intent Structure

The primary pieces of information in an intent are:

  • action -- The general action to be performed, such as ACTION_VIEW, ACTION_EDIT, ACTION_MAIN, etc.

  • data -- The data to operate on, such as a person record in the contacts database, expressed as a Uri.

Some examples of action/data pairs are:

  • ACTION_VIEW content://contacts/people/1 -- Display information about the person whose identifier is "1".

  • ACTION_DIAL content://contacts/people/1 -- Display the phone dialer with the person filled in.

  • ACTION_VIEW tel:123 -- Display the phone dialer with the given number filled in. Note how the VIEW action does what is considered the most reasonable thing for a particular URI.

  • ACTION_DIAL tel:123 -- Display the phone dialer with the given number filled in.

  • ACTION_EDIT content://contacts/people/1 -- Edit information about the person whose identifier is "1".

  • ACTION_VIEW content://contacts/people/ -- Display a list of people, which the user can browse through. This example is a typical top-level entry into the Contacts application, showing you the list of people. Selecting a particular person to view would result in a new intent { ACTION_VIEW content://contacts/people/N } being used to start an activity to display that person.

In addition to these primary attributes, there are a number of secondary attributes that you can also include with an intent:

  • category -- Gives additional information about the action to execute. For example, CATEGORY_LAUNCHER means it should appear in the Launcher as a top-level application, while CATEGORY_ALTERNATIVE means it should be included in a list of alternative actions the user can perform on a piece of data.

  • type -- Specifies an explicit type (a MIME type) of the intent data. Normally the type is inferred from the data itself. By setting this attribute, you disable that evaluation and force an explicit type.

  • component -- Specifies an explicit name of a component class to use for the intent. Normally this is determined by looking at the other information in the intent (the action, data/type, and categories) and matching that with a component that can handle it. If this attribute is set then none of the evaluation is performed, and this component is used exactly as is. By specifying this attribute, all of the other Intent attributes become optional.

  • extras -- This is a Bundle of any additional information. This can be used to provide extended information to the component. For example, if we have a action to send an e-mail message, we could also include extra pieces of data here to supply a subject, body, etc.

Here are some examples of other operations you can specify as intents using these additional parameters:

There are a variety of standard Intent action and category constants defined in the Intent class, but applications can also define their own. These strings use Java-style scoping, to ensure they are unique -- for example, the standard ACTION_VIEW is called "android.intent.action.VIEW".

Put together, the set of actions, data types, categories, and extra data defines a language for the system allowing for the expression of phrases such as "call john smith's cell". As applications are added to the system, they can extend this language by adding new actions, types, and categories, or they can modify the behavior of existing phrases by supplying their own activities that handle them.

Intent Resolution

There are two primary forms of intents you will use.

  • Explicit Intents have specified a component (via setComponent(ComponentName) or setClass(Context, Class)), which provides the exact class to be run. Often these will not include any other information, simply being a way for an application to launch various internal activities it has as the user interacts with the application.

  • Implicit Intents have not specified a component; instead, they must include enough information for the system to determine which of the available components is best to run for that intent.

When using implicit intents, given such an arbitrary intent we need to know what to do with it. This is handled by the process of Intent resolution, which maps an Intent to an Activity, BroadcastReceiver, or Service (or sometimes two or more activities/receivers) that can handle it.

The intent resolution mechanism basically revolves around matching an Intent against all of the <intent-filter> descriptions in the installed application packages. (Plus, in the case of broadcasts, any BroadcastReceiver objects explicitly registered with registerReceiver(BroadcastReceiver, IntentFilter).) More details on this can be found in the documentation on the IntentFilter class.

There are three pieces of information in the Intent that are used for resolution: the action, type, and category. Using this information, a query is done on the PackageManager for a component that can handle the intent. The appropriate component is determined based on the intent information supplied in the AndroidManifest.xml file as follows:

  • The action, if given, must be listed by the component as one it handles.

  • The type is retrieved from the Intent's data, if not already supplied in the Intent. Like the action, if a type is included in the intent (either explicitly or implicitly in its data), then this must be listed by the component as one it handles.

  • For data that is not a content: URI and where no explicit type is included in the Intent, instead the scheme of the intent data (such as http: or mailto:) is considered. Again like the action, if we are matching a scheme it must be listed by the component as one it can handle.
  • The categories, if supplied, must all be listed by the activity as categories it handles. That is, if you include the categories CATEGORY_LAUNCHER and CATEGORY_ALTERNATIVE, then you will only resolve to components with an intent that lists both of those categories. Activities will very often need to support the CATEGORY_DEFAULT so that they can be found by Context.startActivity().

For example, consider the Note Pad sample application that allows user to browse through a list of notes data and view details about individual items. Text in italics indicate places were you would replace a name with one specific to your own package.

             </intent-filter>

         </activity>

         <activity class=".TitleEditor" android:label="@string/title_edit_title"
                 android:theme="@android:style/Theme.Dialog">
             <intent-filter android:label="@string/resolve_title">
                 <action android:name="com.android.notepad.action.EDIT_TITLE" />
                 <category android:name="android.intent.category.DEFAULT" />
                 <category android:name="android.intent.category.ALTERNATIVE" />

                 <data android:mimeType="vnd.android.cursor.item/vnd.google.note" />
             </intent-filter>
         </activity>

     </application>
 </manifest>

The first activity, com.android.notepad.NotesList, serves as our main entry into the app. It can do three things as described by its three intent templates:

  1.  <intent-filter>
         <action android:name="android.intent.action.MAIN" />
         <category android:name="android.intent.category.LAUNCHER" />
     </intent-filter>

    This provides a top-level entry into the NotePad application: the standard MAIN action is a main entry point (not requiring any other information in the Intent), and the LAUNCHER category says that this entry point should be listed in the application launcher.

  2.  <intent-filter>
         <action android:name="android.intent.action.VIEW" />
         <action android:name="android.intent.action.EDIT" />
         <action android:name="android.intent.action.PICK" />
         <category android:name="android.intent.category.DEFAULT" />
         <data android:mimeType="vnd.android.cursor.dir/vnd.google.note" />
     </intent-filter>

    This declares the things that the activity can do on a directory of notes. The type being supported is given with the <type> tag, where vnd.android.cursor.dir/vnd.google.note is a URI from which a Cursor of zero or more items (vnd.android.cursor.dir) can be retrieved which holds our note pad data (vnd.google.note). The activity allows the user to view or edit the directory of data (via the VIEW and EDIT actions), or to pick a particular note and return it to the caller (via the PICK action). Note also the DEFAULT category supplied here: this is required for the Context.startActivity method to resolve your activity when its component name is not explicitly specified.

  3.  <intent-filter>
         <action android:name="android.intent.action.GET_CONTENT" />
         <category android:name="android.intent.category.DEFAULT" />
         <data android:mimeType="vnd.android.cursor.item/vnd.google.note" />
     </intent-filter>

    This filter describes the ability to return to the caller a note selected by the user without needing to know where it came from. The data type vnd.android.cursor.item/vnd.google.note is a URI from which a Cursor of exactly one (vnd.android.cursor.item) item can be retrieved which contains our note pad data (vnd.google.note). The GET_CONTENT action is similar to the PICK action, where the activity will return to its caller a piece of data selected by the user. Here, however, the caller specifies the type of data they desire instead of the type of data the user will be picking from.

Given these capabilities, the following intents will resolve to the NotesList activity:

  • { action=android.app.action.MAIN } matches all of the activities that can be used as top-level entry points into an application.

  • { action=android.app.action.MAIN, category=android.app.category.LAUNCHER } is the actual intent used by the Launcher to populate its top-level list.

  • { action=android.intent.action.VIEW data=content://com.google.provider.NotePad/notes } displays a list of all the notes under "content://com.google.provider.NotePad/notes", which the user can browse through and see the details on.

  • { action=android.app.action.PICK data=content://com.google.provider.NotePad/notes } provides a list of the notes under "content://com.google.provider.NotePad/notes", from which the user can pick a note whose data URL is returned back to the caller.

  • { action=android.app.action.GET_CONTENT type=vnd.android.cursor.item/vnd.google.note } is similar to the pick action, but allows the caller to specify the kind of data they want back so that the system can find the appropriate activity to pick something of that data type.

The second activity, com.android.notepad.NoteEditor, shows the user a single note entry and allows them to edit it. It can do two things as described by its two intent templates:

  1.  <intent-filter android:label="@string/resolve_edit">
         <action android:name="android.intent.action.VIEW" />
         <action android:name="android.intent.action.EDIT" />
         <category android:name="android.intent.category.DEFAULT" />
         <data android:mimeType="vnd.android.cursor.item/vnd.google.note" />
     </intent-filter>

    The first, primary, purpose of this activity is to let the user interact with a single note, as decribed by the MIME type vnd.android.cursor.item/vnd.google.note. The activity can either VIEW a note or allow the user to EDIT it. Again we support the DEFAULT category to allow the activity to be launched without explicitly specifying its component.

  2.  <intent-filter>
         <action android:name="android.intent.action.INSERT" />
         <category android:name="android.intent.category.DEFAULT" />
         <data android:mimeType="vnd.android.cursor.dir/vnd.google.note" />
     </intent-filter>

    The secondary use of this activity is to insert a new note entry into an existing directory of notes. This is used when the user creates a new note: the INSERT action is executed on the directory of notes, causing this activity to run and have the user create the new note data which it then adds to the content provider.

Given these capabilities, the following intents will resolve to the NoteEditor activity:

  • { action=android.intent.action.VIEW data=content://com.google.provider.NotePad/notes/{ID} } shows the user the content of note {ID}.

  • { action=android.app.action.EDIT data=content://com.google.provider.NotePad/notes/{ID} } allows the user to edit the content of note {ID}.

  • { action=android.app.action.INSERT data=content://com.google.provider.NotePad/notes } creates a new, empty note in the notes list at "content://com.google.provider.NotePad/notes" and allows the user to edit it. If they keep their changes, the URI of the newly created note is returned to the caller.

The last activity, com.android.notepad.TitleEditor, allows the user to edit the title of a note. This could be implemented as a class that the application directly invokes (by explicitly setting its component in the Intent), but here we show a way you can publish alternative operations on existing data:

 <intent-filter android:label="@string/resolve_title">
     <action android:name="com.android.notepad.action.EDIT_TITLE" />
     <category android:name="android.intent.category.DEFAULT" />
     <category android:name="android.intent.category.ALTERNATIVE" />
     <category android:name="android.intent.category.SELECTED_ALTERNATIVE" />
     <data android:mimeType="vnd.android.cursor.item/vnd.google.note" />
 </intent-filter>

In the single intent template here, we have created our own private action called com.android.notepad.action.EDIT_TITLE which means to edit the title of a note. It must be invoked on a specific note (data type vnd.android.cursor.item/vnd.google.note) like the previous view and edit actions, but here displays and edits the title contained in the note data.

In addition to supporting the default category as usual, our title editor also supports two other standard categories: ALTERNATIVE and SELECTED_ALTERNATIVE. Implementing these categories allows others to find the special action it provides without directly knowing about it, through the queryIntentActivityOptions(ComponentName, Intent[], Intent, int) method, or more often to build dynamic menu items with addIntentOptions(int, int, int, ComponentName, Intent[], Intent, int, MenuItem[]). Note that in the intent template here was also supply an explicit name for the template (via android:label="@string/resolve_title") to better control what the user sees when presented with this activity as an alternative action to the data they are viewing.

Given these capabilities, the following intent will resolve to the TitleEditor activity:

  • { action=com.android.notepad.action.EDIT_TITLE data=content://com.google.provider.NotePad/notes/{ID} } displays and allows the user to edit the title associated with note {ID}.

Standard Activity Actions

These are the current standard actions that Intent defines for launching activities (usually through startActivity(Intent). The most important, and by far most frequently used, are ACTION_MAIN and ACTION_EDIT.

Standard Broadcast Actions

These are the current standard actions that Intent defines for receiving broadcasts (usually through registerReceiver(BroadcastReceiver, IntentFilter) or a <receiver> tag in a manifest).

Standard Categories

These are the current standard categories that can be used to further clarify an Intent via addCategory(String).

Standard Extra Data

These are the current standard fields that can be used as extra data via putExtra(String, Bundle).

Flags

These are the possible flags that can be used in the Intent via setFlags(int) and addFlags(int). See setFlags(int) for a list of all possible flags.

Input: If nothing, an empty dialer is started; else getData() is URI of a phone number to be dialed or a tel: URI of an explicit phone number.

Output: nothing.

Note: there will be restrictions on which applications can initiate a call; most applications should use the ACTION_DIAL.

Note: this Intent cannot be used to call emergency numbers. Applications can dial emergency numbers using ACTION_DIAL, however.

Note: if you app targets M and above and declares as using the CALL_PHONE permission which is not granted, then attempting to use this action will result in a SecurityException.

Constant Value: "android.intent.action.CALL"

Constant Value: "android.intent.action.CAMERA_BUTTON"

ACTION_CHOOSER

Added in API level 1
String ACTION_CHOOSER

Activity Action: Display an activity chooser, allowing the user to pick what they want to before proceeding. This can be used as an alternative to the standard activity picker that is displayed by the system when you try to start an activity with multiple possible matches, with these differences in behavior:

  • You can specify the title that will appear in the activity chooser.
  • The user does not have the option to make one of the matching activities a preferred activity, and all possible activities will always be shown even if one of them is currently marked as the preferred activity.

This action should be used when the user will naturally expect to select an activity in order to proceed. An example if when not to use it is when the user clicks on a "mailto:" link. They would naturally expect to go directly to their mail app, so startActivity() should be called directly: it will either launch the current preferred app, or put up a dialog allowing the user to pick an app to use and optionally marking that as preferred.

In contrast, if the user is selecting a menu item to send a picture they are viewing to someone else, there are many different things they may want to do at this point: send it through e-mail, upload it to a web service, etc. In this case the CHOOSER action should be used, to always present to the user a list of the things they can do, with a nice title given by the caller such as "Send this photo with:".

If you need to grant URI permissions through a chooser, you must specify the permissions to be granted on the ACTION_CHOOSER Intent in addition to the EXTRA_INTENT inside. This means using setClipData(ClipData) to specify the URIs to be granted as well as FLAG_GRANT_READ_URI_PERMISSION and/or FLAG_GRANT_WRITE_URI_PERMISSION as appropriate.

As a convenience, an Intent of this form can be created with the createChooser(Intent, CharSequence) function.

Input: No data should be specified. get*Extra must have a EXTRA_INTENT field containing the Intent being executed, and can optionally have a EXTRA_TITLE field containing the title text to display in the chooser.

Output: Depends on the protocol of EXTRA_INTENT.

Constant Value: "android.intent.action.CHOOSER"

ACTION_CLOSE_SYSTEM_DIALOGS

Added in API level 1
String ACTION_CLOSE_SYSTEM_DIALOGS

Broadcast Action: This is broadcast when a user action should request a temporary system dialog to dismiss. Some examples of temporary system dialogs are the notification window-shade and the recent tasks dialog.

Constant Value: "android.intent.action.CLOSE_SYSTEM_DIALOGS"

ACTION_CONFIGURATION_CHANGED

Added in API level 1
String ACTION_CONFIGURATION_CHANGED

Broadcast Action: The current device Configuration (orientation, locale, etc) has changed. When such a change happens, the UIs (view hierarchy) will need to be rebuilt based on this new information; for the most part, applications don't need to worry about this, because the system will take care of stopping and restarting the application to make sure it sees the new changes. Some system code that can not be restarted will need to watch for this action and handle it appropriately.

You cannot receive this through components declared in manifests, only by explicitly registering for it with Context.registerReceiver().

This is a protected intent that can only be sent by the system.

See also:

Constant Value: "android.intent.action.CONFIGURATION_CHANGED"

ACTION_CREATE_DOCUMENT

Added in API level 19
String ACTION_CREATE_DOCUMENT

Activity Action: Allow the user to create a new document. When invoked, the system will display the various DocumentsProvider instances installed on the device, letting the user navigate through them. The returned document may be a newly created document with no content, or it may be an existing document with the requested MIME type.

Each document is represented as a content:// URI backed by a DocumentsProvider, which can be opened as a stream with openFileDescriptor(Uri, String), or queried for DocumentsContract.Document metadata.

Callers must indicate the concrete MIME type of the document being created by setting setType(String). This MIME type cannot be changed after the document is created.

Callers can provide an initial display name through EXTRA_TITLE, but the user may change this value before creating the file.

Callers must include CATEGORY_OPENABLE in the Intent to obtain URIs that can be opened with openFileDescriptor(Uri, String).

Output: The URI of the item that was created. This must be a content:// URI so that any receiver can access it.

Input: nothing

Output: nothing

Constant Value: "android.intent.action.FACTORY_TEST"

ACTION_GET_CONTENT

Added in API level 1
String ACTION_GET_CONTENT

Activity Action: Allow the user to select a particular kind of data and return it. This is different than ACTION_PICK in that here we just say what kind of data is desired, not a URI of existing data from which the user can pick. An ACTION_GET_CONTENT could allow the user to create the data as it runs (for example taking a picture or recording a sound), let them browse over the web and download the desired data, etc.

There are two main ways to use this action: if you want a specific kind of data, such as a person contact, you set the MIME type to the kind of data you want and launch it with startActivity(Intent). The system will then launch the best application to select that kind of data for you.

You may also be interested in any of a set of types of content the user can pick. For example, an e-mail application that wants to allow the user to add an attachment to an e-mail message can use this action to bring up a list of all of the types of content the user can attach.

In this case, you should wrap the GET_CONTENT intent with a chooser (through createChooser(Intent, CharSequence)), which will give the proper interface for the user to pick how to send your data and allow you to specify a prompt indicating what they are doing. You will usually specify a broad MIME type (such as image/* or */*), resulting in a broad range of content types the user can select from.

When using such a broad GET_CONTENT action, it is often desirable to only pick from data that can be represented as a stream. This is accomplished by requiring the CATEGORY_OPENABLE in the Intent.

Callers can optionally specify EXTRA_LOCAL_ONLY to request that the launched content chooser only returns results representing data that is locally available on the device. For example, if this extra is set to true then an image picker should not show any pictures that are available from a remote server but not already on the local device (thus requiring they be downloaded when opened).

If the caller can handle multiple returned items (the user performing multiple selection), then it can specify EXTRA_ALLOW_MULTIPLE to indicate this.

Input: getType() is the desired MIME type to retrieve. Note that no URI is supplied in the intent, as there are no constraints on where the returned data originally comes from. You may also include the CATEGORY_OPENABLE if you can only accept data that can be opened as a stream. You may use EXTRA_LOCAL_ONLY to limit content selection to local data. You may use EXTRA_ALLOW_MULTIPLE to allow the user to select multiple items.

Output: The URI of the item that was picked. This must be a content: URI so that any receiver can access it.

Constant Value: "android.intent.action.GET_CONTENT"

ACTION_GET_RESTRICTION_ENTRIES

Added in API level 18
String ACTION_GET_RESTRICTION_ENTRIES

Broadcast to a specific application to query any supported restrictions to impose on restricted users. The broadcast intent contains an extra EXTRA_RESTRICTIONS_BUNDLE with the currently persisted restrictions as a Bundle of key/value pairs. The value types can be Boolean, String or String[] depending on the restriction type.

The response should contain an extra EXTRA_RESTRICTIONS_LIST, which is of type ArrayList<RestrictionEntry>. It can also contain an extra EXTRA_RESTRICTIONS_INTENT, which is of type Intent. The activity specified by that intent will be launched for a result which must contain one of the extras EXTRA_RESTRICTIONS_LIST or EXTRA_RESTRICTIONS_BUNDLE. The keys and values of the returned restrictions will be persisted.

ACTION_INSTALL_PACKAGE

Added in API level 14

Broadcast Action: A new version of your application has been installed over an existing one. This is only sent to the application that was replaced. It does not contain any additional data; to receive it, just use an intent filter for this action.

This is a protected intent that can only be sent by the system.

Constant Value: "android.intent.action.MY_PACKAGE_REPLACED"

ACTION_NEW_OUTGOING_CALL

Added in API level 1
String ACTION_NEW_OUTGOING_CALL

Broadcast Action: An outgoing call is about to be placed.

The Intent will have the following extra value:

Once the broadcast is finished, the resultData is used as the actual number to call. If null, no call will be placed.

It is perfectly acceptable for multiple receivers to process the outgoing call in turn: for example, a parental control application might verify that the user is authorized to place the call at that time, then a number-rewriting application might add an area code if one was not specified.

For consistency, any receiver whose purpose is to prohibit phone calls should have a priority of 0, to ensure it will see the final phone number to be dialed. Any receiver whose purpose is to rewrite phone numbers to be called should have a positive priority. Negative priorities are reserved for the system for this broadcast; using them may cause problems.

Any BroadcastReceiver receiving this Intent must not abort the broadcast.

Emergency calls cannot be intercepted using this mechanism, and other calls cannot be modified to call emergency numbers using this mechanism.

Some apps (such as VoIP apps) may want to redirect the outgoing call to use their own service instead. Those apps should first prevent the call from being placed by setting resultData to null and then start their own app to make the call.

You must hold the PROCESS_OUTGOING_CALLS permission to receive this Intent.

This is a protected intent that can only be sent by the system.

Constant Value: "android.intent.action.NEW_OUTGOING_CALL"

ACTION_OPEN_DOCUMENT

Added in API level 19
String ACTION_OPEN_DOCUMENT

Activity Action: Allow the user to select and return one or more existing documents. When invoked, the system will display the various DocumentsProvider instances installed on the device, letting the user interactively navigate through them. These documents include local media, such as photos and video, and documents provided by installed cloud storage providers.

Each document is represented as a content:// URI backed by a DocumentsProvider, which can be opened as a stream with openFileDescriptor(Uri, String), or queried for DocumentsContract.Document metadata.

All selected documents are returned to the calling application with persistable read and write permission grants. If you want to maintain access to the documents across device reboots, you need to explicitly take the persistable permissions using takePersistableUriPermission(Uri, int).

Callers must indicate the acceptable document MIME types through setType(String). For example, to select photos, use image/*. If multiple disjoint MIME types are acceptable, define them in EXTRA_MIME_TYPES and setType(String) to */*.

If the caller can handle multiple returned items (the user performing multiple selection), then you can specify EXTRA_ALLOW_MULTIPLE to indicate this.

Callers must include CATEGORY_OPENABLE in the Intent to obtain URIs that can be opened with openFileDescriptor(Uri, String).

Output: The URI of the item that was picked, returned in getData(). This must be a content:// URI so that any receiver can access it. If multiple documents were selected, they are returned in getClipData().

Constant Value: "android.intent.action.OPEN_DOCUMENT"

ACTION_OPEN_DOCUMENT_TREE

Added in API level 21
String ACTION_OPEN_DOCUMENT_TREE

String ACTION_PROVIDER_CHANGED

Broadcast Action: Some content providers have parts of their namespace where they publish new events or items that the user may be especially interested in. For these things, they may broadcast this action when the set of interesting items change. For example, GmailProvider sends this notification when the set of unread mail in the inbox changes.

The data of the intent identifies which part of which provider changed. When queried through the content resolver, the data URI will return the data set in question.

The intent will have the following extra values:

  • count - The number of items in the data set. This is the same as the number of items in the cursor returned by querying the data URI.
This intent will be sent at boot (if the count is non-zero) and when the data set changes. It is possible for the data set to change without the count changing (for example, if a new unread message arrives in the same sync operation in which a message is archived). The phone should still ring/vibrate/etc as normal in this case.

ACTION_SCREEN_OFF

Added in API level 1
String ACTION_SCREEN_OFF

Broadcast Action: Sent when the device goes to sleep and becomes non-interactive.

For historical reasons, the name of this broadcast action refers to the power state of the screen but it is actually sent in response to changes in the overall interactive state of the device.

This broadcast is sent when the device becomes non-interactive which may have nothing to do with the screen turning off. To determine the actual state of the screen, use getState().

See isInteractive() for details.

You cannot receive this through components declared in manifests, only by explicitly registering for it with Context.registerReceiver().

This is a protected intent that can only be sent by the system.

Constant Value: "android.intent.action.SCREEN_OFF"

ACTION_SCREEN_ON

Added in API level 1
String ACTION_SCREEN_ON

Broadcast Action: Sent when the device wakes up and becomes interactive.

For historical reasons, the name of this broadcast action refers to the power state of the screen but it is actually sent in response to changes in the overall interactive state of the device.

This broadcast is sent when the device becomes interactive which may have nothing to do with the screen turning on. To determine the actual state of the screen, use getState().

See isInteractive() for details.

You cannot receive this through components declared in manifests, only by explicitly registering for it with Context.registerReceiver().

This is a protected intent that can only be sent by the system.

Constant Value: "android.intent.action.SCREEN_ON"

Constant Value: "android.intent.action.SEARCH_LONG_PRESS"

ACTION_SEND

Added in API level 1
String ACTION_SEND

Activity Action: Deliver some data to someone else. Who the data is being delivered to is not specified; it is up to the receiver of this action to ask the user where the data should be sent.

When launching a SEND intent, you should usually wrap it in a chooser (through createChooser(Intent, CharSequence)), which will give the proper interface for the user to pick how to send your data and allow you to specify a prompt indicating what they are doing.

Input: getType() is the MIME type of the data being sent. get*Extra can have either a EXTRA_TEXT or EXTRA_STREAM field, containing the data to be sent. If using EXTRA_TEXT, the MIME type should be "text/plain"; otherwise it should be the MIME type of the data in EXTRA_STREAM. Use */* if the MIME type is unknown (this will only allow senders that can handle generic data streams). If using EXTRA_TEXT, you can also optionally supply EXTRA_HTML_TEXT for clients to retrieve your text with HTML formatting.

As of JELLY_BEAN, the data being sent can be supplied through setClipData(ClipData). This allows you to use FLAG_GRANT_READ_URI_PERMISSION when sharing content: URIs and other advanced features of ClipData. If using this approach, you still must supply the same data through the EXTRA_TEXT or EXTRA_STREAM fields described below for compatibility with old applications. If you don't set a ClipData, it will be copied there for you when calling startActivity(Intent).

Optional standard extras, which may be interpreted by some recipients as appropriate, are: EXTRA_EMAIL, EXTRA_CC, EXTRA_BCC, EXTRA_SUBJECT.

Output: nothing.

Constant Value: "android.intent.action.SEND"

ACTION_SENDTO

Added in API level 1
String ACTION_SENDTO

Activity Action: Send a message to someone specified by the data.

Output: nothing.

Constant Value: "android.intent.action.SENDTO"

ACTION_SEND_MULTIPLE

Added in API level 4
String ACTION_SEND_MULTIPLE

Activity Action: Deliver multiple data to someone else.

Like ACTION_SEND, except the data is multiple.

Input: getType() is the MIME type of the data being sent. get*ArrayListExtra can have either a EXTRA_TEXT or EXTRA_STREAM field, containing the data to be sent. If using EXTRA_TEXT, you can also optionally supply EXTRA_HTML_TEXT for clients to retrieve your text with HTML formatting.

Multiple types are supported, and receivers should handle mixed types whenever possible. The right way for the receiver to check them is to use the content resolver on each URI. The intent sender should try to put the most concrete mime type in the intent type, but it can fall back to <type>/* or */* as needed.

e.g. if you are sending image/jpg and image/jpg, the intent's type can be image/jpg, but if you are sending image/jpg and image/png, then the intent's type should be image/*.

As of JELLY_BEAN, the data being sent can be supplied through setClipData(ClipData). This allows you to use FLAG_GRANT_READ_URI_PERMISSION when sharing content: URIs and other advanced features of ClipData. If using this approach, you still must supply the same data through the EXTRA_TEXT or EXTRA_STREAM fields described below for compatibility with old applications. If you don't set a ClipData, it will be copied there for you when calling startActivity(Intent).

Optional standard extras, which may be interpreted by some recipients as appropriate, are: EXTRA_EMAIL, EXTRA_CC, EXTRA_BCC, EXTRA_SUBJECT.

Output: nothing.

Constant Value: "android.intent.action.SEND_MULTIPLE"

Input: EXTRA_PACKAGE_NAME specifies the package whose information needs to be displayed.

Output: Nothing.

Constant Value: "android.intent.action.SHOW_APP_INFO"

ACTION_SHUTDOWN

Added in API level 4
String ACTION_SHUTDOWN

Broadcast Action: Device is shutting down. This is broadcast when the device is being shut down (completely turned off, not sleeping). Once the broadcast is complete, the final shutdown will proceed and all unsaved data lost. Apps will not normally need to handle this, since the foreground activity will be paused as well.

This is a protected intent that can only be sent by the system.

May include the following extras:

Constant Value: "android.intent.action.ACTION_SHUTDOWN"

ACTION_SYNC

ACTION_USER_INITIALIZE

Added in API level 17
String ACTION_USER_INITIALIZE

Sent the first time a user is starting, to allow system apps to perform one time initialization. (This will not be seen by third party applications because a newly initialized user does not have any third party applications installed for it.) This is sent early in starting the user, around the time the home app is started, before ACTION_BOOT_COMPLETED is sent.

Constant Value: "android.intent.action.USER_UNLOCKED"

ACTION_VIEW

Added in API level 1
String ACTION_VIEW

Activity Action: Display the data to the user. This is the most common action performed on data -- it is the generic action you can use on a piece of data to get the most reasonable thing to occur. For example, when used on a contacts entry it will view the entry; when used on a mailto: URI it will bring up a compose window filled with the information supplied by the URI; when used with a tel: URI it will invoke the dialer.

ACTION_WALLPAPER_CHANGED

Added in API level 1
String ACTION_WALLPAPER_CHANGED

This constant was deprecated in API level 16.
Modern applications should use WindowManager.LayoutParams.FLAG_SHOW_WALLPAPER to have the wallpaper shown behind their UI, rather than watching for this broadcast and rendering the wallpaper on their own.

Broadcast Action: The current system wallpaper has changed. See WallpaperManager for retrieving the new wallpaper. This should only be used to determine when the wallpaper has changed to show the new wallpaper to the user. You should certainly never, in response to this, change the wallpaper or other attributes of it such as the suggested size. That would be crazy, right? You'd cause all kinds of loops, especially if other apps are doing similar things, right? Of course. So please don't do this.

Constant Value: "android.intent.action.WALLPAPER_CHANGED"

ACTION_WEB_SEARCH

Added in API level 1
String ACTION_WEB_SEARCH

CATEGORY_ALTERNATIVE

Added in API level 1
String CATEGORY_ALTERNATIVE

Set if the activity should be considered as an alternative action to the data the user is currently viewing. See also CATEGORY_SELECTED_ALTERNATIVE for an alternative action that applies to the selection in a list of items.

Supporting this category means that you would like your activity to be displayed in the set of alternative things the user can do, usually as part of the current activity's options menu. You will usually want to include a specific label in the <intent-filter> of this action describing to the user what it does.

The action of IntentFilter with this category is important in that it describes the specific action the target will perform. This generally should not be a generic action (such as ACTION_VIEW, but rather a specific name such as "com.android.camera.action.CROP. Only one alternative of any particular action will be shown to the user, so using a specific action like this makes sure that your alternative will be displayed while also allowing other applications to provide their own overrides of that particular action.

Constant Value: "android.intent.category.ALTERNATIVE"

CATEGORY_APP_BROWSER

Added in API level 15
String CATEGORY_APP_BROWSER

Used with ACTION_MAIN to launch the browser application. The activity should be able to browse the Internet.

A Bundle forming a mapping of potential target package names to different extras Bundles to add to the default intent extras in EXTRA_INTENT when used with ACTION_CHOOSER. Each key should be a package name. The package need not be currently installed on the device.

An application may choose to provide alternate extras for the case where a user selects an activity from a predetermined set of target packages. If the activity the user selects from the chooser belongs to a package with its package name as a key in this bundle, the corresponding extras for that package will be merged with the extras already present in the intent at EXTRA_INTENT. If a replacement extra has the same key as an extra already present in the intent it will overwrite the extra from the intent.

Examples:

  • An application may offer different EXTRA_TEXT to an application when sharing with it via ACTION_SEND, augmenting a link with additional query parameters for that target.
  • An application may offer additional metadata for known targets of a given intent to pass along information only relevant to that target such as account or content identifiers already known to that application.

Constant Value: "android.intent.extra.REPLACEMENT_EXTRAS"

If EXTRA_CHOOSER_REFINEMENT_INTENT_SENDER is present in the intent used to start a ACTION_CHOOSER activity this extra will be filled in to that IntentSender and sent when the user selects a target component from the chooser. It is up to the recipient to send a result to this ResultReceiver to signal that disambiguation is complete and that the chooser should invoke the user's choice.

The disambiguator should provide a Bundle to the ResultReceiver with an intent assigned to the key EXTRA_INTENT. This supplied intent will be used by the chooser to match and fill in the final Intent or ChooserTarget before starting it. The supplied intent must match one of the intents from EXTRA_INTENT or EXTRA_ALTERNATE_INTENTS passed to EXTRA_CHOOSER_REFINEMENT_INTENT_SENDER to be accepted.

The result code passed to the ResultReceiver should be RESULT_OK if the refinement succeeded and the supplied intent's target in the chooser should be started, or RESULT_CANCELED if the chooser should finish without starting a target.

A content: URI holding a stream of data associated with the Intent, used with ACTION_SEND to supply the data being sent.

Constant Value: "android.intent.extra.STREAM"

EXTRA_SUBJECT

Added in API level 1
String EXTRA_SUBJECT

A constant string holding the desired subject line of a message.

Constant Value: "android.intent.extra.SUBJECT"

EXTRA_TEXT

Added in API level 1
String EXTRA_TEXT

A constant CharSequence that is associated with the Intent, used with ACTION_SEND to supply the literal data to be sent. Note that this may be a styled CharSequence, so you must use Bundle.getCharSequence() to retrieve it.

Constant Value: "android.intent.extra.TEXT"

EXTRA_TITLE

Added in API level 1
String EXTRA_TITLE

A CharSequence dialog title to provide to the user when used with a ACTION_CHOOSER.

Constant Value: "android.intent.extra.TITLE"

Added in API level 16
int FILL_IN_CLIP_DATA

Use with fillIn(Intent, int) to allow the current ClipData to be overwritten, even if it is already set.

Constant Value: 128 (0x00000080)

FILL_IN_COMPONENT

Added in API level 1
int FILL_IN_COMPONENT

Use with fillIn(Intent, int) to allow the current component value to be overwritten, even if it is already set.

Constant Value: 8 (0x00000008)

FILL_IN_DATA

Added in API level 1
int FILL_IN_DATA

Use with fillIn(Intent, int) to allow the current data or type value overwritten, even if it is already set.

Constant Value: 2 (0x00000002)

FILL_IN_PACKAGE

Added in API level 4
int FILL_IN_PACKAGE

Use with fillIn(Intent, int) to allow the current package value to be overwritten, even if it is already set.

Constant Value: 16 (0x00000010)

FILL_IN_SELECTOR

Added in API level 15
int FILL_IN_SELECTOR

Use with fillIn(Intent, int) to allow the current selector to be overwritten, even if it is already set.

FILL_IN_SOURCE_BOUNDS

Added in API level 7
int FILL_IN_SOURCE_BOUNDS

Use with fillIn(Intent, int) to allow the current bounds rectangle to be overwritten, even if it is already set.

Constant Value: 32 (0x00000020)

FLAG_ACTIVITY_BROUGHT_TO_FRONT

Added in API level 1
int FLAG_ACTIVITY_BROUGHT_TO_FRONT

This flag is not normally set by application code, but set for you by the system as described in the launchMode documentation for the singleTask mode.

Constant Value: 4194304 (0x00400000)

FLAG_ACTIVITY_CLEAR_TASK

Added in API level 11
int FLAG_ACTIVITY_CLEAR_TASK

If set in an Intent passed to Context.startActivity(), this flag will cause any existing task that would be associated with the activity to be cleared before the activity is started. That is, the activity becomes the new root of an otherwise empty task, and any old activities are finished. This can only be used in conjunction with FLAG_ACTIVITY_NEW_TASK.

Constant Value: 32768 (0x00008000)

FLAG_ACTIVITY_CLEAR_TOP

Added in API level 1
int FLAG_ACTIVITY_CLEAR_TOP

If set, and the activity being launched is already running in the current task, then instead of launching a new instance of that activity, all of the other activities on top of it will be closed and this Intent will be delivered to the (now on top) old activity as a new Intent.

For example, consider a task consisting of the activities: A, B, C, D. If D calls startActivity() with an Intent that resolves to the component of activity B, then C and D will be finished and B receive the given Intent, resulting in the stack now being: A, B.

The currently running instance of activity B in the above example will either receive the new intent you are starting here in its onNewIntent() method, or be itself finished and restarted with the new intent. If it has declared its launch mode to be "multiple" (the default) and you have not set FLAG_ACTIVITY_SINGLE_TOP in the same intent, then it will be finished and re-created; for all other launch modes or if FLAG_ACTIVITY_SINGLE_TOP is set then this Intent will be delivered to the current instance's onNewIntent().

This launch mode can also be used to good effect in conjunction with FLAG_ACTIVITY_NEW_TASK: if used to start the root activity of a task, it will bring any currently running instance of that task to the foreground, and then clear it to its root state. This is especially useful, for example, when launching an activity from the notification manager.

See Tasks and Back Stack for more information about tasks.

Constant Value: 67108864 (0x04000000)

FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET

Added in API level 3
int FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET

This constant was deprecated in API level 21.
As of API 21 this performs identically to FLAG_ACTIVITY_NEW_DOCUMENT which should be used instead of this.

Constant Value: 524288 (0x00080000)

FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS

Added in API level 1
int FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS

If set, the new activity is not kept in the list of recently launched activities.

Constant Value: 8388608 (0x00800000)

FLAG_ACTIVITY_FORWARD_RESULT

Added in API level 1
int FLAG_ACTIVITY_FORWARD_RESULT

If set and this intent is being used to launch a new activity from an existing one, then the reply target of the existing activity will be transfered to the new activity. This way the new activity can call setResult(int) and have that result sent back to the reply target of the original activity.

Constant Value: 33554432 (0x02000000)

FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY

Added in API level 1
int FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY

This flag is not normally set by application code, but set for you by the system if this activity is being launched from history (longpress home key).

Constant Value: 1048576 (0x00100000)

FLAG_ACTIVITY_LAUNCH_ADJACENT

Added in API level 24
int FLAG_ACTIVITY_LAUNCH_ADJACENT

This flag is only used in split-screen multi-window mode. The new activity will be displayed adjacent to the one launching it. This can only be used in conjunction with FLAG_ACTIVITY_NEW_TASK. Also, setting FLAG_ACTIVITY_MULTIPLE_TASK is required if you want a new instance of an existing activity to be created.

Constant Value: 4096 (0x00001000)

FLAG_ACTIVITY_MULTIPLE_TASK

Added in API level 1
int FLAG_ACTIVITY_MULTIPLE_TASK

This flag is used to create a new task and launch an activity into it. This flag is always paired with either FLAG_ACTIVITY_NEW_DOCUMENT or FLAG_ACTIVITY_NEW_TASK. In both cases these flags alone would search through existing tasks for ones matching this Intent. Only if no such task is found would a new task be created. When paired with FLAG_ACTIVITY_MULTIPLE_TASK both of these behaviors are modified to skip the search for a matching task and unconditionally start a new task. When used with FLAG_ACTIVITY_NEW_TASK do not use this flag unless you are implementing your own top-level application launcher. Used in conjunction with FLAG_ACTIVITY_NEW_TASK to disable the behavior of bringing an existing task to the foreground. When set, a new task is always started to host the Activity for the Intent, regardless of whether there is already an existing task running the same thing.

Because the default system does not include graphical task management, you should not use this flag unless you provide some way for a user to return back to the tasks you have launched. See FLAG_ACTIVITY_NEW_DOCUMENT for details of this flag's use for creating new document tasks.

This flag is ignored if one of FLAG_ACTIVITY_NEW_TASK or FLAG_ACTIVITY_NEW_DOCUMENT is not also set.

See Tasks and Back Stack for more information about tasks.

See also:

Constant Value: 134217728 (0x08000000)

FLAG_ACTIVITY_NEW_DOCUMENT

Added in API level 21
int FLAG_ACTIVITY_NEW_DOCUMENT

This flag is used to open a document into a new task rooted at the activity launched by this Intent. Through the use of this flag, or its equivalent attribute, documentLaunchMode multiple instances of the same activity containing different documents will appear in the recent tasks list.

The use of the activity attribute form of this, documentLaunchMode, is preferred over the Intent flag described here. The attribute form allows the Activity to specify multiple document behavior for all launchers of the Activity whereas using this flag requires each Intent that launches the Activity to specify it.

Note that the default semantics of this flag w.r.t. whether the recents entry for it is kept after the activity is finished is different than the use of FLAG_ACTIVITY_NEW_TASK and documentLaunchMode -- if this flag is being used to create a new recents entry, then by default that entry will be removed once the activity is finished. You can modify this behavior with FLAG_ACTIVITY_RETAIN_IN_RECENTS.

FLAG_ACTIVITY_NEW_DOCUMENT may be used in conjunction with FLAG_ACTIVITY_MULTIPLE_TASK. When used alone it is the equivalent of the Activity manifest specifying documentLaunchMode="intoExisting". When used with FLAG_ACTIVITY_MULTIPLE_TASK it is the equivalent of the Activity manifest specifying documentLaunchMode="always". Refer to documentLaunchMode for more information.

Constant Value: 524288 (0x00080000)

FLAG_ACTIVITY_NEW_TASK

Added in API level 1
int FLAG_ACTIVITY_NEW_TASK

If set, this activity will become the start of a new task on this history stack. A task (from the activity that started it to the next task activity) defines an atomic group of activities that the user can move to. Tasks can be moved to the foreground and background; all of the activities inside of a particular task always remain in the same order. See Tasks and Back Stack for more information about tasks.

This flag is generally used by activities that want to present a "launcher" style behavior: they give the user a list of separate things that can be done, which otherwise run completely independently of the activity launching them.

When using this flag, if a task is already running for the activity you are now starting, then a new activity will not be started; instead, the current task will simply be brought to the front of the screen with the state it was last in. See FLAG_ACTIVITY_MULTIPLE_TASK for a flag to disable this behavior.

This flag can not be used when the caller is requesting a result from the activity being launched.

Constant Value: 268435456 (0x10000000)

FLAG_ACTIVITY_NO_ANIMATION

Added in API level 5
int FLAG_ACTIVITY_NO_ANIMATION

If set in an Intent passed to Context.startActivity(), this flag will prevent the system from applying an activity transition animation to go to the next activity state. This doesn't mean an animation will never run -- if another activity change happens that doesn't specify this flag before the activity started here is displayed, then that transition will be used. This flag can be put to good use when you are going to do a series of activity operations but the animation seen by the user shouldn't be driven by the first activity change but rather a later one.

Constant Value: 65536 (0x00010000)

FLAG_ACTIVITY_NO_HISTORY

Added in API level 1
int FLAG_ACTIVITY_NO_HISTORY

If set, the new activity is not kept in the history stack. As soon as the user navigates away from it, the activity is finished. This may also be set with the noHistory attribute.

If set, onActivityResult() is never invoked when the current activity starts a new activity which sets a result and finishes.

Constant Value: 1073741824 (0x40000000)

FLAG_ACTIVITY_NO_USER_ACTION

Added in API level 3
int FLAG_ACTIVITY_NO_USER_ACTION

If set, this flag will prevent the normal onUserLeaveHint() callback from occurring on the current frontmost activity before it is paused as the newly-started activity is brought to the front.

Typically, an activity can rely on that callback to indicate that an explicit user action has caused their activity to be moved out of the foreground. The callback marks an appropriate point in the activity's lifecycle for it to dismiss any notifications that it intends to display "until the user has seen them," such as a blinking LED.

If an activity is ever started via any non-user-driven events such as phone-call receipt or an alarm handler, this flag should be passed to Context.startActivity, ensuring that the pausing activity does not think the user has acknowledged its notification.

Constant Value: 262144 (0x00040000)

FLAG_ACTIVITY_PREVIOUS_IS_TOP

Added in API level 1
int FLAG_ACTIVITY_PREVIOUS_IS_TOP

If set and this intent is being used to launch a new activity from an existing one, the current activity will not be counted as the top activity for deciding whether the new intent should be delivered to the top instead of starting a new one. The previous activity will be used as the top, with the assumption being that the current activity will finish itself immediately.

Constant Value: 16777216 (0x01000000)

FLAG_ACTIVITY_REORDER_TO_FRONT

Added in API level 3
int FLAG_ACTIVITY_REORDER_TO_FRONT

If set in an Intent passed to Context.startActivity(), this flag will cause the launched activity to be brought to the front of its task's history stack if it is already running.

For example, consider a task consisting of four activities: A, B, C, D. If D calls startActivity() with an Intent that resolves to the component of activity B, then B will be brought to the front of the history stack, with this resulting order: A, C, D, B. This flag will be ignored if FLAG_ACTIVITY_CLEAR_TOP is also specified.

Constant Value: 131072 (0x00020000)

FLAG_ACTIVITY_RESET_TASK_IF_NEEDED

Added in API level 1
int FLAG_ACTIVITY_RESET_TASK_IF_NEEDED

If set, and this activity is either being started in a new task or bringing to the top an existing task, then it will be launched as the front door of the task. This will result in the application of any affinities needed to have that task in the proper state (either moving activities to or from it), or simply resetting that task to its initial state if needed.

Constant Value: 2097152 (0x00200000)

FLAG_ACTIVITY_RETAIN_IN_RECENTS

Added in API level 21
int FLAG_ACTIVITY_RETAIN_IN_RECENTS

By default a document created by FLAG_ACTIVITY_NEW_DOCUMENT will have its entry in recent tasks removed when the user closes it (with back or however else it may finish()). If you would like to instead allow the document to be kept in recents so that it can be re-launched, you can use this flag. When set and the task's activity is finished, the recents entry will remain in the interface for the user to re-launch it, like a recents entry for a top-level application.

The receiving activity can override this request with autoRemoveFromRecents or by explcitly calling Activity.finishAndRemoveTask().

Constant Value: 8192 (0x00002000)

FLAG_ACTIVITY_SINGLE_TOP

Added in API level 1
int FLAG_ACTIVITY_SINGLE_TOP

If set, the activity will not be launched if it is already running at the top of the history stack.

Constant Value: 536870912 (0x20000000)

FLAG_ACTIVITY_TASK_ON_HOME

Added in API level 11
int FLAG_ACTIVITY_TASK_ON_HOME

If set in an Intent passed to Context.startActivity(), this flag will cause a newly launching task to be placed on top of the current home activity task (if there is one). That is, pressing back from the task will always return the user to home even if that was not the last activity they saw. This can only be used in conjunction with FLAG_ACTIVITY_NEW_TASK.

Constant Value: 16384 (0x00004000)

FLAG_DEBUG_LOG_RESOLUTION

Added in API level 1
int FLAG_DEBUG_LOG_RESOLUTION

A flag you can enable for debugging: when set, log messages will be printed during the resolution of this intent to show you what has been found to create the final resolved list.

Constant Value: 8 (0x00000008)

FLAG_EXCLUDE_STOPPED_PACKAGES

Added in API level 12
int FLAG_EXCLUDE_STOPPED_PACKAGES

If set, this intent will not match any components in packages that are currently stopped. If this is not set, then the default behavior is to include such applications in the result.

Constant Value: 16 (0x00000010)

FLAG_FROM_BACKGROUND

Added in API level 1
int FLAG_FROM_BACKGROUND

Can be set by the caller to indicate that this Intent is coming from a background operation, not from direct user interaction.

Constant Value: 4 (0x00000004)

FLAG_GRANT_PERSISTABLE_URI_PERMISSION

Added in API level 19
int FLAG_GRANT_PERSISTABLE_URI_PERMISSION

When combined with FLAG_GRANT_READ_URI_PERMISSION and/or FLAG_GRANT_WRITE_URI_PERMISSION, the URI permission grant can be persisted across device reboots until explicitly revoked with revokeUriPermission(Uri, int). This flag only offers the grant for possible persisting; the receiving application must call takePersistableUriPermission(Uri, int) to actually persist.

See also:

Constant Value: 64 (0x00000040)

FLAG_GRANT_PREFIX_URI_PERMISSION

Added in API level 21
int FLAG_GRANT_PREFIX_URI_PERMISSION

When combined with FLAG_GRANT_READ_URI_PERMISSION and/or FLAG_GRANT_WRITE_URI_PERMISSION, the URI permission grant applies to any URI that is a prefix match against the original granted URI. (Without this flag, the URI must match exactly for access to be granted.) Another URI is considered a prefix match only when scheme, authority, and all path segments defined by the prefix are an exact match.

Constant Value: 128 (0x00000080)

FLAG_GRANT_READ_URI_PERMISSION

Added in API level 1
int FLAG_GRANT_READ_URI_PERMISSION

If set, the recipient of this Intent will be granted permission to perform read operations on the URI in the Intent's data and any URIs specified in its ClipData. When applying to an Intent's ClipData, all URIs as well as recursive traversals through data or other ClipData in Intent items will be granted; only the grant flags of the top-level Intent are used.

Constant Value: 1 (0x00000001)

FLAG_GRANT_WRITE_URI_PERMISSION

Added in API level 1
int FLAG_GRANT_WRITE_URI_PERMISSION

If set, the recipient of this Intent will be granted permission to perform write operations on the URI in the Intent's data and any URIs specified in its ClipData. When applying to an Intent's ClipData, all URIs as well as recursive traversals through data or other ClipData in Intent items will be granted; only the grant flags of the top-level Intent are used.

Constant Value: 2 (0x00000002)

FLAG_INCLUDE_STOPPED_PACKAGES

Added in API level 12
int FLAG_INCLUDE_STOPPED_PACKAGES

If set, this intent will always match any components in packages that are currently stopped. This is the default behavior when FLAG_EXCLUDE_STOPPED_PACKAGES is not set. If both of these flags are set, this one wins (it allows overriding of exclude for places where the framework may automatically set the exclude flag).

Constant Value: 32 (0x00000020)

FLAG_RECEIVER_FOREGROUND

Added in API level 16
int FLAG_RECEIVER_FOREGROUND

If set, when sending a broadcast the recipient is allowed to run at foreground priority, with a shorter timeout interval. During normal broadcasts the receivers are not automatically hoisted out of the background priority class.

Constant Value: 268435456 (0x10000000)

FLAG_RECEIVER_NO_ABORT

Added in API level 19
int FLAG_RECEIVER_NO_ABORT

If this is an ordered broadcast, don't allow receivers to abort the broadcast. They can still propagate results through to later receivers, but they can not prevent later receivers from seeing the broadcast.

Constant Value: 134217728 (0x08000000)

FLAG_RECEIVER_REGISTERED_ONLY

Added in API level 1
int FLAG_RECEIVER_REGISTERED_ONLY

If set, when sending a broadcast only registered receivers will be called -- no BroadcastReceiver components will be launched.

Constant Value: 1073741824 (0x40000000)

FLAG_RECEIVER_REPLACE_PENDING

Added in API level 8
int FLAG_RECEIVER_REPLACE_PENDING

If set, when sending a broadcast the new broadcast will replace any existing pending broadcast that matches it. Matching is defined by Intent.filterEquals returning true for the intents of the two broadcasts. When a match is found, the new broadcast (and receivers associated with it) will replace the existing one in the pending broadcast list, remaining at the same position in the list.

This flag is most typically used with sticky broadcasts, which only care about delivering the most recent values of the broadcast to their receivers.

Constant Value: 536870912 (0x20000000)

METADATA_DOCK_HOME

Added in API level 5
String METADATA_DOCK_HOME

Boolean that can be supplied as meta-data with a dock activity, to indicate that the dock should take over the home key when it is active.

Constant Value: "android.dock_home"

URI_ALLOW_UNSAFE

Added in API level 22
int URI_ALLOW_UNSAFE

Flag for use with toUri(int) and parseUri(String, int): allow parsing of unsafe information. In particular, the flags FLAG_GRANT_READ_URI_PERMISSION, FLAG_GRANT_WRITE_URI_PERMISSION, FLAG_GRANT_PERSISTABLE_URI_PERMISSION, and FLAG_GRANT_PREFIX_URI_PERMISSION flags can not be set, so that the generated Intent can not cause unexpected data access to happen.

If you do not trust the source of the URI being parsed, you should still do further processing to protect yourself from it. In particular, when using it to start an activity you should usually add in CATEGORY_BROWSABLE to limit the activities that can handle it.

Constant Value: 4 (0x00000004)

URI_ANDROID_APP_SCHEME

Added in API level 22
int URI_ANDROID_APP_SCHEME

Flag for use with toUri(int) and parseUri(String, int): the URI string always has the "android-app:" scheme. This is a variation of URI_INTENT_SCHEME whose format is simpler for the case of an http/https URI being delivered to a specific package name. The format is:

 android-app://{package_id}[/{scheme}[/{host}[/{path}]]][#Intent;{...}]

In this scheme, only the package_id is required. If you include a host, you must also include a scheme; including a path also requires both a host and a scheme. The final #Intent; fragment can be used without a scheme, host, or path. Note that this can not be used with intents that have a setSelector(Intent), since the base intent will always have an explicit package name.

Some examples of how this scheme maps to Intent objects:

URI Intent
android-app://com.example.app
Action: ACTION_MAIN
Package: com.example.app
android-app://com.example.app/http/example.com
Action: ACTION_VIEW
Data: http://example.com/
Package: com.example.app
android-app://com.example.app/http/example.com/foo?1234
Action: ACTION_VIEW
Data: http://example.com/foo?1234
Package: com.example.app
android-app://com.example.app/
#Intent;action=com.example.MY_ACTION;end
Action: com.example.MY_ACTION
Package: com.example.app
android-app://com.example.app/http/example.com/foo?1234
#Intent;action=com.example.MY_ACTION;end
Action: com.example.MY_ACTION
Data: http://example.com/foo?1234
Package: com.example.app
android-app://com.example.app/
#Intent;action=com.example.MY_ACTION;
i.some_int=100;S.some_str=hello;end
Action: com.example.MY_ACTION
Package: com.example.app
Extras: some_int=(int)100
some_str=(String)hello

Constant Value: 2 (0x00000002)

URI_INTENT_SCHEME

Added in API level 4
int URI_INTENT_SCHEME

Flag for use with toUri(int) and parseUri(String, int): the URI string always has the "intent:" scheme. This syntax can be used when you want to later disambiguate between URIs that are intended to describe an Intent vs. all others that should be treated as raw URIs. When used with parseUri(String, int), any other scheme will result in a generic VIEW action for that raw URI.

Constant Value: 1 (0x00000001)

Fields

CREATOR

Added in API level 1
Creator<Intent> CREATOR

Public constructors

Intent

Added in API level 1
Intent ()

Create an empty intent.

Intent

Added in API level 1
Intent (Intent o)

Copy constructor.

Parameters
o Intent

Intent

Added in API level 1
Intent (String action)

Create an intent with a given action. All other fields (data, type, class) are null. Note that the action must be in a namespace because Intents are used globally in the system -- for example the system VIEW action is android.intent.action.VIEW; an application's custom action would be something like com.google.app.myapp.CUSTOM_ACTION.

Parameters
action String: The Intent action, such as ACTION_VIEW.

Intent

Added in API level 1
Intent (String action, 
                Uri uri)

Create an intent with a given action and for a given data url. Note that the action must be in a namespace because Intents are used globally in the system -- for example the system VIEW action is android.intent.action.VIEW; an application's custom action would be something like com.google.app.myapp.CUSTOM_ACTION.

Note: scheme and host name matching in the Android framework is case-sensitive, unlike the formal RFC. As a result, you should always ensure that you write your Uri with these elements using lower case letters, and normalize any Uris you receive from outside of Android to ensure the scheme and host is lower case.

Parameters
action String: The Intent action, such as ACTION_VIEW.
uri Uri: The Intent data URI.

Intent

Added in API level 1
Intent (Context packageContext, 
                Class<?> cls)

Create an intent for a specific component. All other fields (action, data, type, class) are null, though they can be modified later with explicit calls. This provides a convenient way to create an intent that is intended to execute a hard-coded class name, rather than relying on the system to find an appropriate class for you; see setComponent(ComponentName) for more information on the repercussions of this.

Parameters
packageContext Context: A Context of the application package implementing this class.
cls Class: The component class that is to be used for the intent.

See also:

Intent

Added in API level 1
Intent (String action, 
                Uri uri, 
                Context packageContext, 
                Class<?> cls)

Create an intent for a specific component with a specified action and data. This is equivalent to using Intent(String, android.net.Uri) to construct the Intent and then calling setClass(Context, Class) to set its class.

Note: scheme and host name matching in the Android framework is case-sensitive, unlike the formal RFC. As a result, you should always ensure that you write your Uri with these elements using lower case letters, and normalize any Uris you receive from outside of Android to ensure the scheme and host is lower case.

Parameters
action String: The Intent action, such as ACTION_VIEW.
uri Uri: The Intent data URI.
packageContext Context: A Context of the application package implementing this class.
cls Class: The component class that is to be used for the intent.

Public methods

addCategory

Added in API level 1
Intent addCategory (String category)

Add a new category to the intent. Categories provide additional detail about the action the intent performs. When resolving an intent, only activities that provide all of the requested categories will be used.

Parameters
category String: The desired category. This can be either one of the predefined Intent categories, or a custom category in your own namespace.
Returns
Intent Returns the same Intent object, for chaining multiple calls into a single statement.

See also:

addFlags

Added in API level 1
Intent addFlags (int flags)

Add additional flags to the intent (or with existing flags value).

Parameters
flags int: The new flags to set.
Returns
Intent Returns the same Intent object, for chaining multiple calls into a single statement.

See also:

clone

Added in API level 1
Object clone ()

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression:

 x.clone() != x
will be true, and that the expression:
 x.clone().getClass() == x.getClass()
will be true, but these are not absolute requirements. While it is typically the case that:
 x.clone().equals(x)
will be true, this is not an absolute requirement.

By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

The method clone for class Object performs a specific cloning operation. First, if the class of this object does not implement the interface Cloneable, then a CloneNotSupportedException is thrown. Note that all arrays are considered to implement the interface Cloneable and that the return type of the clone method of an array type T[] is T[] where T is any reference or primitive type. Otherwise, this method creates a new instance of the class of this object and initializes all its fields with exactly the contents of the corresponding fields of this object, as if by assignment; the contents of the fields are not themselves cloned. Thus, this method performs a "shallow copy" of this object, not a "deep copy" operation.

The class Object does not itself implement the interface Cloneable, so calling the clone method on an object whose class is Object will result in throwing an exception at run time.

Returns
Object a clone of this instance.

cloneFilter

Added in API level 1
Intent cloneFilter ()

Make a clone of only the parts of the Intent that are relevant for filter matching: the action, data, type, component, and categories.

createChooser

Added in API level 22
Intent createChooser (Intent target, 
                CharSequence title, 
                IntentSender sender)

Convenience function for creating a ACTION_CHOOSER Intent.

Builds a new ACTION_CHOOSER Intent that wraps the given target intent, also optionally supplying a title. If the target intent has specified FLAG_GRANT_READ_URI_PERMISSION or FLAG_GRANT_WRITE_URI_PERMISSION, then these flags will also be set in the returned chooser intent, with its ClipData set appropriately: either a direct reflection of getClipData() if that is non-null, or a new ClipData built from getData().

The caller may optionally supply an IntentSender to receive a callback when the user makes a choice. This can be useful if the calling application wants to remember the last chosen target and surface it as a more prominent or one-touch affordance elsewhere in the UI for next time.

Parameters
target Intent: The Intent that the user will be selecting an activity to perform.
title CharSequence: Optional title that will be displayed in the chooser.
sender IntentSender: Optional IntentSender to be called when a choice is made.
Returns
Intent Return a new Intent object that you can hand to Context.startActivity() and related methods.

createChooser

Added in API level 1
Intent createChooser (Intent target, 
                CharSequence title)

Convenience function for creating a ACTION_CHOOSER Intent.

Builds a new ACTION_CHOOSER Intent that wraps the given target intent, also optionally supplying a title. If the target intent has specified FLAG_GRANT_READ_URI_PERMISSION or FLAG_GRANT_WRITE_URI_PERMISSION, then these flags will also be set in the returned chooser intent, with its ClipData set appropriately: either a direct reflection of getClipData() if that is non-null, or a new ClipData built from getData().

Parameters
target Intent: The Intent that the user will be selecting an activity to perform.
title CharSequence: Optional title that will be displayed in the chooser.
Returns
Intent Return a new Intent object that you can hand to Context.startActivity() and related methods.

describeContents

Added in API level 1

fillIn

Added in API level 1
int fillIn (Intent other, 
                int flags)

Copy the contents of other in to this object, but only where fields are not defined by this object. For purposes of a field being defined, the following pieces of data in the Intent are considered to be separate fields:

In addition, you can use the FILL_IN_ACTION, FILL_IN_DATA, FILL_IN_CATEGORIES, FILL_IN_PACKAGE, FILL_IN_COMPONENT, FILL_IN_SOURCE_BOUNDS, FILL_IN_SELECTOR, and FILL_IN_CLIP_DATA to override the restriction where the corresponding field will not be replaced if it is already set.

Note: The component field will only be copied if FILL_IN_COMPONENT is explicitly specified. The selector will only be copied if FILL_IN_SELECTOR is explicitly specified.

For example, consider Intent A with {data="foo", categories="bar"} and Intent B with {action="gotit", data-type="some/thing", categories="one","two"}.

Calling A.fillIn(B, Intent.FILL_IN_DATA) will result in A now containing: {action="gotit", data-type="some/thing", categories="bar"}.

Parameters
other Intent: Another Intent whose values are to be used to fill in the current one.
flags int: Options to control which fields can be filled in.
Returns
int Returns a bit mask of FILL_IN_ACTION, FILL_IN_DATA, FILL_IN_CATEGORIES, FILL_IN_PACKAGE, FILL_IN_COMPONENT, FILL_IN_SOURCE_BOUNDS, FILL_IN_SELECTOR and {@link #FILL_IN_CLIP_DATA indicating which fields were changed.

makeMainActivity

Added in API level 11
Intent makeMainActivity (ComponentName mainActivity)

Create an intent to launch the main (root) activity of a task. This is the Intent that is started when the application's is launched from Home. For anything else that wants to launch an application in the same way, it is important that they use an Intent structured the same way, and can use this function to ensure this is the case.

The returned Intent has the given Activity component as its explicit component, ACTION_MAIN as its action, and includes the category CATEGORY_LAUNCHER. This does not have FLAG_ACTIVITY_NEW_TASK set, though typically you will want to do that through addFlags(int) on the returned Intent.

Parameters
mainActivity ComponentName: The main activity component that this Intent will launch.
Returns
Intent Returns a newly created Intent that can be used to launch the activity as a main application entry.

See also:

makeMainSelectorActivity

Added in API level 15
Intent makeMainSelectorActivity (String selectorAction, 
                String selectorCategory)

Make an Intent for the main activity of an application, without specifying a specific activity to run but giving a selector to find the activity. This results in a final Intent that is structured the same as when the application is launched from Home. For anything else that wants to launch an application in the same way, it is important that they use an Intent structured the same way, and can use this function to ensure this is the case.

The returned Intent has ACTION_MAIN as its action, and includes the category CATEGORY_LAUNCHER. This does not have FLAG_ACTIVITY_NEW_TASK set, though typically you will want to do that through addFlags(int) on the returned Intent.

Parameters
selectorAction String: The action name of the Intent's selector.

Parameters
mainActivity ComponentName: The activity component that is the root of the task; this is the activity that has been published in the application's manifest as the main launcher icon.
Returns
Intent Returns a newly created Intent that can be used to relaunch the activity's task in its root state.

normalizeMimeType

Added in API level 16
String normalizeMimeType (String type)

For example, "text/plain; charset=utf-8" becomes "text/plain". "text/x-vCard" becomes "text/x-vcard".

All MIME types received from outside Android (such as user input, or external sources like Bluetooth, NFC, or the Internet) should be normalized before they are used to create an Intent.

Parameters
type String: MIME data type to normalize
Returns
String normalized MIME data type, or null if the input was null

The given XML parser should be located at the tag where parsing should start (often named "intent"), from which the basic action, data, type, and package and class name will be retrieved. The function will then parse in to any child elements, looking for tags to add categories and to attach extra data to the intent.

Parameters
resources Resources: The Resources to use when inflating resources.
parser XmlPullParser: The XML parser pointing at an "intent" tag.
attrs AttributeSet: The AttributeSet interface for retrieving extended attribute data at the current parser location.
Returns

The URI given here must not be relative -- that is, it must include the scheme and full path.

Parameters
uri String: The URI to turn into an Intent.
flags int: Additional processing flags. Either 0, URI_INTENT_SCHEME, or URI_ANDROID_APP_SCHEME.
Returns

resolveActivity

Added in API level 1
ComponentName resolveActivity (PackageManager pm)

Return the Activity component that should be used to handle this intent. The appropriate component is determined based on the information in the intent, evaluated as follows:

If getComponent() returns an explicit class, that is returned without any further consideration.

The activity must handle the CATEGORY_DEFAULT Intent category to be considered.

If getAction() is non-NULL, the activity must handle this action.

If resolveType(ContentResolver) returns non-NULL, the activity must handle this type.

If addCategory(String) has added any categories, the activity must handle ALL of the categories specified.

If getPackage() is non-NULL, only activity components in that application package will be considered.

If there are no activities that satisfy all of these conditions, a null string is returned.

If multiple activities are found to satisfy the intent, the one with the highest priority will be used. If there are multiple activities with the same priority, the system will either pick the best activity based on user preference, or resolve to a system class that will allow the user to pick an activity and forward from there.

This method is implemented simply by calling resolveActivity(Intent, int) with the "defaultOnly" parameter true.

This API is called for you as part of starting an activity from an intent. You do not normally need to call it yourself.

Parameters
pm PackageManager: The package manager with which to resolve the Intent.
Returns
ComponentName Name of the component implementing an activity that can display the intent.

See also:

resolveActivityInfo

Added in API level 1
ActivityInfo resolveActivityInfo (PackageManager pm, 
                int flags)

Resolve the Intent into an ActivityInfo describing the activity that should execute the intent. Resolution follows the same rules as described for resolveActivity(PackageManager), but you get back the completely information about the resolved activity instead of just its class name.

Parameters
pm PackageManager: The package manager with which to resolve the Intent.
flags int: Addition information to retrieve as per PackageManager.getActivityInfo().
Returns
ActivityInfo PackageManager.ActivityInfo

See also:

resolveType

Added in API level 1
String resolveType (Context context)

Return the MIME data type of this intent. If the type field is explicitly set, that is simply returned. Otherwise, if the data is set, the type of that data is returned. If neither fields are set, a null is returned.

Parameters
context Context
Returns
String The MIME type of this intent.

See also:

resolveType

Added in API level 1
String resolveType (ContentResolver resolver)

Parameters
resolver ContentResolver: A ContentResolver that can be used to determine the MIME type of the intent's data.
Returns
String The MIME type of this intent.

See also:

resolveTypeIfNeeded

Added in API level 1
String resolveTypeIfNeeded (ContentResolver resolver)

Return the MIME data type of this intent, only if it will be needed for intent resolution. This is not generally useful for application code; it is used by the frameworks for communicating with back-end system services.

Parameters
resolver ContentResolver: A ContentResolver that can be used to determine the MIME type of the intent's data.
Returns
String The MIME type of this intent, or null if it is unknown or not needed.

setAction

Intent setAction (String action)

Set the general action to be performed.

Parameters
action String: An action name, such as ACTION_VIEW. Application-specific actions should be prefixed with the vendor's package name.
Returns
Intent Returns the same Intent object, for chaining multiple calls into a single statement.

See also:

setClass

Added in API level 1
Intent setClass (Context packageContext, 
                Class<?> cls)

Convenience for calling setComponent(ComponentName) with the name returned by a Class object.

Parameters
packageContext Context: A Context of the application package implementing this class.
cls Class: The class name to set, equivalent to setClassName(context, cls.getName()).

className String: The name of a class inside of the application package that will be used as the component for this Intent.
Returns
Intent Returns the same Intent object, for chaining multiple calls into a single statement.

See also:

setClipData

Added in API level 16
void setClipData (ClipData clip)

Set a ClipData associated with this Intent. This replaces any previously set ClipData.

The ClipData in an intent is not used for Intent matching or other such operations. Semantically it is like extras, used to transmit additional data with the Intent. The main feature of using this over the extras for data is that FLAG_GRANT_READ_URI_PERMISSION and FLAG_GRANT_WRITE_URI_PERMISSION will operate on any URI items included in the clip data. This is useful, in particular, if you want to transmit an Intent containing multiple content: URIs for which the recipient may not have global permission to access the content provider.

If the ClipData contains items that are themselves Intents, any grant flags in those Intents will be ignored. Only the top-level flags of the main Intent are respected, and will be applied to all Uri or Intent items in the clip (or sub-items of the clip).

The MIME type, label, and icon in the ClipData object are not directly used by Intent. Applications should generally rely on the MIME type of the Intent itself, not what it may find in the ClipData. A common practice is to construct a ClipData for use with an Intent with a MIME type of "*/*".

Parameters
clip ClipData: The new clip to set. May be null to clear the current clip.

setComponent

Added in API level 1
Intent setComponent (ComponentName component)

(Usually optional) Explicitly set the component to handle the intent. If left with the default value of null, the system will determine the appropriate class to use based on the other fields (action, data, type, categories) in the Intent. If this class is defined, the specified class will always be used regardless of the other fields. You should only set this value when you know you absolutely want a specific class to be used; otherwise it is better to let the system find the appropriate class so that you will respect the installed applications and user preferences.

Parameters
component ComponentName: The name of the application component to handle the intent, or null to let the system find one for you.
Returns
Intent Returns the same Intent object, for chaining multiple calls into a single statement.

See also:

setData

Added in API level 1
Intent setData (Uri data)

Set the data this intent is operating on. This method automatically clears any type that was previously set by setType(String) or setTypeAndNormalize(String).

Note: scheme matching in the Android framework is case-sensitive, unlike the formal RFC. As a result, you should always write your Uri with a lower case scheme, or use normalizeScheme() or setDataAndNormalize(Uri) to ensure that the scheme is converted to lower case.

Parameters
data Uri: The Uri of the data this intent is now targeting.
Returns
Intent Returns the same Intent object, for chaining multiple calls into a single statement.

See also:

setDataAndNormalize

Added in API level 16
Intent setDataAndNormalize (Uri data)

Normalize and set the data this intent is operating on.

This method automatically clears any type that was previously set (for example, by setType(String)).

The data Uri is normalized using normalizeScheme() before it is set, so really this is just a convenience method for

 setData(data.normalize())
 

Parameters
data Uri: The Uri of the data this intent is now targeting.
Returns
Intent Returns the same Intent object, for chaining multiple calls into a single statement.

See also:

setDataAndType

Added in API level 1
Intent setDataAndType (Uri data, 
                String type)

(Usually optional) Set the data for the intent along with an explicit MIME data type. This method should very rarely be used -- it allows you to override the MIME type that would ordinarily be inferred from the data with your own type given here.

Note: MIME type and Uri scheme matching in the Android framework is case-sensitive, unlike the formal RFC definitions. As a result, you should always write these elements with lower case letters, or use normalizeMimeType(String) or normalizeScheme() or setDataAndTypeAndNormalize(Uri, String) to ensure that they are converted to lower case.

Parameters
data Uri: The Uri of the data this intent is now targeting.
type String: The MIME type of the data being handled by this intent.
Returns
Intent Returns the same Intent object, for chaining multiple calls into a single statement.

See also:

setDataAndTypeAndNormalize

Added in API level 16
Intent setDataAndTypeAndNormalize (Uri data, 
                String type)

(Usually optional) Normalize and set both the data Uri and an explicit MIME data type. This method should very rarely be used -- it allows you to override the MIME type that would ordinarily be inferred from the data with your own type given here.

The data Uri and the MIME type are normalize using normalizeScheme() and normalizeMimeType(String) before they are set, so really this is just a convenience method for

 setDataAndType(data.normalize(), Intent.normalizeMimeType(type))
 

Parameters
data Uri: The Uri of the data this intent is now targeting.
type String: The MIME type of the data being handled by this intent.
Returns
Intent Returns the same Intent object, for chaining multiple calls into a single statement.

See also:

setExtrasClassLoader

Added in API level 1
void setExtrasClassLoader (ClassLoader loader)

Sets the ClassLoader that will be used when unmarshalling any Parcelable values from the extras of this Intent.

Parameters
loader ClassLoader: a ClassLoader, or null to use the default loader at the time of unmarshalling.

setFlags

Added in API level 1
Intent setFlags (int flags)

Set special flags controlling how this intent is handled. Most values here depend on the type of component being executed by the Intent, specifically the FLAG_ACTIVITY_* flags are all for use with Context.startActivity() and the FLAG_RECEIVER_* flags are all for use with Context.sendBroadcast().

See the Tasks and Back Stack documentation for important information on how some of these options impact the behavior of your application.

Parameters
flags int: The desired flags.
Returns
Intent Returns the same Intent object, for chaining multiple calls into a single statement.

See also:

setPackage

Added in API level 4
Intent setPackage (String packageName)

(Usually optional) Set an explicit application package name that limits the components this Intent will resolve to. If left to the default value of null, all components in all applications will considered. If non-null, the Intent can only match the components in the given application package.

Parameters
packageName String: The name of the application package to handle the intent, or null to allow any application package.
Returns
Intent Returns the same Intent object, for chaining multiple calls into a single statement.

See also:

setSelector

Added in API level 15
void setSelector (Intent selector)

Set a selector for this Intent. This is a modification to the kinds of things the Intent will match. If the selector is set, it will be used when trying to find entities that can handle the Intent, instead of the main contents of the Intent. This allows you build an Intent containing a generic protocol while targeting it more specifically.

An example of where this may be used is with things like CATEGORY_APP_BROWSER. This category allows you to build an Intent that will launch the Browser application. However, the correct main entry point of an application is actually ACTION_MAIN CATEGORY_LAUNCHER with setComponent(ComponentName) used to specify the actual Activity to launch. If you launch the browser with something different, undesired behavior may happen if the user has previously or later launches it the normal way, since they do not match. Instead, you can build an Intent with the MAIN action (but no ComponentName yet specified) and set a selector with ACTION_MAIN and CATEGORY_APP_BROWSER to point it specifically to the browser activity.

Setting a selector does not impact the behavior of filterEquals(Intent) and filterHashCode(). This is part of the desired behavior of a selector -- it does not impact the base meaning of the Intent, just what kinds of things will be matched against it when determining who can handle it.

You can not use both a selector and setPackage(String) on the same base Intent.

Parameters
selector Intent: The desired selector Intent; set to null to not use a special selector.

setSourceBounds

Added in API level 7
void setSourceBounds (Rect r)

Set the bounds of the sender of this intent, in screen coordinates. This can be used as a hint to the receiver for animations and the like. Null means that there is no source bounds.

Parameters
r Rect

setType

Added in API level 1
Intent setType (String type)

Set an explicit MIME data type.

This is used to create intents that only specify a type and not data, for example to indicate the type of data to return.

This method automatically clears any data that was previously set (for example by setData(Uri)).

Note: MIME type matching in the Android framework is case-sensitive, unlike formal RFC MIME types. As a result, you should always write your MIME types with lower case letters, or use normalizeMimeType(String) or setTypeAndNormalize(String) to ensure that it is converted to lower case.

Parameters
type String: The MIME type of the data being handled by this intent.
Returns
Intent Returns the same Intent object, for chaining multiple calls into a single statement.

See also:

setTypeAndNormalize

Added in API level 16
Intent setTypeAndNormalize (String type)

Normalize and set an explicit MIME data type.

This is used to create intents that only specify a type and not data, for example to indicate the type of data to return.

This method automatically clears any data that was previously set (for example by setData(Uri)).

The MIME type is normalized using normalizeMimeType(String) before it is set, so really this is just a convenience method for

 setType(Intent.normalizeMimeType(type))
 

Parameters
type String: The MIME type of the data being handled by this intent.
Returns
Intent Returns the same Intent object, for chaining multiple calls into a single statement.

See also:

toString

Added in API level 1
String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Returns
String a string representation of the object.

toURI

Added in API level 1
String toURI ()

This method was deprecated in API level 4.
Use toUri(int) instead.

Call toUri(int) with 0 flags.

Returns
String

toUri

Added in API level 4
String toUri (int flags)

Convert this Intent into a String holding a URI representation of it. The returned URI string has been properly URI encoded, so it can be used with Uri.parse(String). The URI contains the Intent's data as the base URI, with an additional fragment describing the action, categories, type, flags, package, component, and extras.

You can convert the returned string back to an Intent with getIntent(String).

Parameters
flags int: Additional operating flags. Either 0, URI_INTENT_SCHEME, or URI_ANDROID_APP_SCHEME.
Returns
String Returns a URI encoding URI string describing the entire contents of the Intent.

writeToParcel

Added in API level 1
void writeToParcel (Parcel out, 
                int flags)

Flatten this object in to a Parcel.

Parameters
out Parcel: The Parcel in which the object should be written.
flags int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
