ACTION_DOCUMENT_SETTINGS

public static final String ACTION_DOCUMENT_SETTINGS

Action of intent issued by DocumentsUI when user wishes to open/configure/manage a particular document in the provider application.

When issued, the intent will include the URI of the document as the intent data.

A provider wishing to provide support for this action should do two things.

EXTRA_ERROR

public static final String EXTRA_ERROR

Optional string included in a directory Cursor#getExtras() providing an error message that should be shown to a user. For example, a provider may wish to indicate that a network error occurred. The user may choose to retry, resulting in a new query.

Constant Value: "error"

EXTRA_EXCLUDE_SELF

public static final String EXTRA_EXCLUDE_SELF

Set this in a DocumentsUI intent to cause a package's own roots to be excluded from the roots list.

Constant Value: "android.provider.extra.EXCLUDE_SELF"

EXTRA_INFO

public static final String EXTRA_INFO

Optional string included in a directory Cursor#getExtras() providing an informational message that should be shown to a user. For example, a provider may wish to indicate that not all documents are available.

Constant Value: "info"

EXTRA_INITIAL_URI

public static final String EXTRA_INITIAL_URI

Sets the desired initial location visible to user when file chooser is shown.

Applicable to Intent with actions:

• Intent#ACTION_OPEN_DOCUMENT
• Intent#ACTION_CREATE_DOCUMENT
• Intent#ACTION_OPEN_DOCUMENT_TREE

Location should specify a document URI or a tree URI with document ID. If this URI identifies a non-directory, document navigator will attempt to use the parent of the document as the initial location.

The initial location is system specific if this extra is missing or document navigator failed to locate the desired initial location.

Constant Value: "android.provider.extra.INITIAL_URI"

EXTRA_LOADING

public static final String EXTRA_LOADING

Optional boolean flag included in a directory Cursor#getExtras() indicating that a document provider is still loading data. For example, a provider has returned some results, but is still waiting on an outstanding network request. The provider must send a content changed notification when loading is finished.

Constant Value: "loading"

buildChildDocumentsUri

public static Uri buildChildDocumentsUri (String authority, 
                String parentDocumentId)

Build URI representing the children of the target directory in a document provider. When queried, a provider will return zero or more rows with columns defined by Document.

buildChildDocumentsUriUsingTree

public static Uri buildChildDocumentsUriUsingTree (Uri treeUri, 
                String parentDocumentId)

Build URI representing the children of the target directory in a document provider. When queried, a provider will return zero or more rows with columns defined by Document.

However, instead of directly accessing the target directory, the returned URI will leverage access granted through a subtree URI, typically returned by Intent#ACTION_OPEN_DOCUMENT_TREE. The target directory must be a descendant (child, grandchild, etc) of the subtree.

This is typically used to access documents under a user-selected directory tree, since it doesn't require the user to separately confirm each new document access.

buildDocumentUri

public static Uri buildDocumentUri (String authority, 
                String documentId)

Build URI representing the target Document#COLUMN_DOCUMENT_ID in a document provider. When queried, a provider will return a single row with columns defined by Document.

buildDocumentUriUsingTree

public static Uri buildDocumentUriUsingTree (Uri treeUri, 
                String documentId)

Build URI representing the target Document#COLUMN_DOCUMENT_ID in a document provider. When queried, a provider will return a single row with columns defined by Document.

However, instead of directly accessing the target document, the returned URI will leverage access granted through a subtree URI, typically returned by Intent#ACTION_OPEN_DOCUMENT_TREE. The target document must be a descendant (child, grandchild, etc) of the subtree.

This is typically used to access documents under a user-selected directory tree, since it doesn't require the user to separately confirm each new document access.

buildRecentDocumentsUri

public static Uri buildRecentDocumentsUri (String authority, 
                String rootId)

Build URI representing the recently modified documents of a specific root in a document provider. When queried, a provider will return zero or more rows with columns defined by Document.

                String rootId)

Build URI representing the given Root#COLUMN_ROOT_ID in a document provider.

buildRootsUri

public static Uri buildRootsUri (String authority)

                String rootId, 
                String query)

Build URI representing a search for matching documents under a specific root in a document provider. When queried, a provider will return zero or more rows with columns defined by Document.

buildTreeDocumentUri

public static Uri buildTreeDocumentUri (String authority, 
                String documentId)

Build URI representing access to descendant documents of the given Document#COLUMN_DOCUMENT_ID.

copyDocument

public static Uri copyDocument (ContentResolver content, 
                Uri sourceDocumentUri, 
                Uri targetParentDocumentUri)

Copies the given document.

createDocument

public static Uri createDocument (ContentResolver content, 
                Uri parentDocumentUri, 
                String mimeType, 
                String displayName)

Create a new document with given MIME type and display name.

createWebLinkIntent

public static IntentSender createWebLinkIntent (ContentResolver content, 
                Uri uri, 
                Bundle options)

Creates an intent for obtaining a web link for the specified document.

Note, that due to internal limitations, if there is already a web link intent created for the specified document but with different options, then it may be overridden.

Providers are required to show confirmation UI for all new permissions granted for the linked document.

If list of recipients is known, then it should be passed in options as Intent#EXTRA_EMAIL as a list of email addresses. Note, that this is just a hint for the provider, which can ignore the list. In either case the provider is required to show a UI for letting the user confirm any new permission grants.

Note, that the entire options bundle will be sent to the provider backing the passed uri. Make sure that you trust the provider before passing any sensitive information.

Since this API may show a UI, it cannot be called from background.

In order to obtain the Web Link use code like this:

 void onSomethingHappened() {
   IntentSender sender = DocumentsContract.createWebLinkIntent(...);
   if (sender != null) {
     startIntentSenderForResult(
         sender,
         WEB_LINK_REQUEST_CODE,
         null, 0, 0, 0, null);
   }
 }

 (...)

 void onActivityResult(int requestCode, int resultCode, Intent data) {
   if (requestCode == WEB_LINK_REQUEST_CODE && resultCode == RESULT_OK) {
     Uri weblinkUri = data.getData();
     ...
   }
 }
 

deleteDocument

public static boolean deleteDocument (ContentResolver content, 
                Uri documentUri)

Delete the given document.

ejectRoot

public static void ejectRoot (ContentResolver content, 
                Uri rootUri)

findDocumentPath

public static DocumentsContract.Path findDocumentPath (ContentResolver content, 
                Uri treeUri)

Finds the canonical path from the top of the document tree. The Path#getPath() of the return value contains the document ID of all documents along the path from the top the document tree to the requested document, both inclusive. The Path#getRootId() of the return value returns null.

getDocumentId

public static String getDocumentId (Uri documentUri)

Extract the Document#COLUMN_DOCUMENT_ID from the given URI.

getDocumentMetadata

public static Bundle getDocumentMetadata (ContentResolver content, 
                Uri documentUri)

Returns metadata associated with the document. The type of metadata returned is specific to the document type. For example the data returned for an image file will likely consist primarily or solely of EXIF metadata.

The returned Bundle will contain zero or more entries depending on the type of data supported by the document provider.

1. A DocumentsContract#METADATA_TYPES containing a String[] value. The string array identifies the type or types of metadata returned. Each value in the can be used to access a Bundle of data containing that type of data.
2. An entry each for each type of returned metadata. Each set of metadata is itself represented as a bundle and accessible via a string key naming the type of data.

Example:

     Bundle metadata = DocumentsContract.getDocumentMetadata(client, imageDocUri, tags);
     if (metadata.containsKey(DocumentsContract.METADATA_EXIF)) {
         Bundle exif = metadata.getBundle(DocumentsContract.METADATA_EXIF);
         int imageLength = exif.getInt(ExifInterface.TAG_IMAGE_LENGTH);
     }
 

getDocumentThumbnail

public static Bitmap getDocumentThumbnail (ContentResolver content, 
                Uri documentUri, 
                Point size,

getRootId

public static String getRootId (Uri rootUri)

Extract the Root#COLUMN_ROOT_ID from the given URI.

getSearchDocumentsQuery

public static String getSearchDocumentsQuery (Uri searchDocumentsUri)

public static boolean isChildDocument (ContentResolver content, 
                Uri parentDocumentUri, 
                Uri childDocumentUri)

Test if a document is descendant (child, grandchild, etc) from the given parent.

isDocumentUri

public static boolean isDocumentUri (Context context, 
                Uri uri)

Test if the given URI represents a Document backed by a DocumentsProvider.

isRootUri

moveDocument

public static Uri moveDocument (ContentResolver content, 
                Uri sourceDocumentUri, 
                Uri sourceParentDocumentUri, 
                Uri targetParentDocumentUri)

Moves the given document under a new parent.

removeDocument

public static boolean removeDocument (ContentResolver content, 
                Uri documentUri, 
                Uri parentDocumentUri)

Removes the given document from a parent directory.

In contrast to deleteDocument(ContentResolver, Uri) it requires specifying the parent. This method is especially useful if the document can be in multiple parents.

renameDocument

public static Uri renameDocument (ContentResolver content, 
                Uri documentUri, 
                String displayName)

Change the display name of an existing document.

If the underlying provider needs to create a new Document#COLUMN_DOCUMENT_ID to represent the updated display name, that new document is returned and the original document is no longer valid. Otherwise, the original document is returned.
