Constants

public static final int COMPONENT_ENABLED_STATE_DEFAULT

Added in API level 1

Flag for setApplicationEnabledSetting(String, int, int) and setComponentEnabledSetting(ComponentName, int, int): This component or application is in its default enabled state (as specified in its manifest).

Constant Value: 0 (0x00000000)

public static final int COMPONENT_ENABLED_STATE_DISABLED

Added in API level 1

Flag for setApplicationEnabledSetting(String, int, int) and setComponentEnabledSetting(ComponentName, int, int): This component or application has been explicitly disabled, regardless of what it has specified in its manifest.

public static final int COMPONENT_ENABLED_STATE_DISABLED_UNTIL_USED

Added in API level 18

Flag for setApplicationEnabledSetting(String, int, int) only: This application should be considered, until the point where the user actually wants to use it. This means that it will not normally show up to the user (such as in the launcher), but various parts of the user interface can use GET_DISABLED_UNTIL_USED_COMPONENTS to still see it and allow the user to select it (as for example an IME, device admin, etc). Such code, once the user has selected the app, should at that point also make it enabled. This option currently can not be used with setComponentEnabledSetting(ComponentName, int, int).

Constant Value: 4 (0x00000004)

public static final int COMPONENT_ENABLED_STATE_DISABLED_USER

Added in API level 14

Flag for setApplicationEnabledSetting(String, int, int) only: The user has explicitly disabled the application, regardless of what it has specified in its manifest.

Public Constructors

public PackageManager ()

Added in API level 1

Public Methods

public abstract void addPackageToPreferred (String packageName)

Added in API level 1

This method was deprecated in API level 7.
This function no longer does anything; it was an old approach to managing preferred activities, which has been superseded by (and conflicts with) the modern activity-based preferences.

public abstract boolean addPermission (PermissionInfo info)

Added in API level 1

Add a new dynamic permission to the system. For this to work, your package must have defined a permission tree through the <permission-tree> tag in its manifest. A package can only add permissions to trees that were defined by either its own package or another with the same user id; a permission is in a tree if it matches the name of the permission tree + ".": for example, "com.foo.bar" is a member of the permission tree "com.foo".

It is good to make your permission tree name descriptive, because you are taking possession of that entire set of permission names. Thus, it must be under a domain you control, with a suffix that will not match any normal permissions that may be declared in any applications that are part of that domain.

New permissions must be added before any .apks are installed that use those permissions. Permissions you add through this method are remembered across reboots of the device. If the given permission already exists, the info you supply here will be used to update it.

Parameters
info Description of the permission to be added.
Returns
  • Returns true if a new permission was created, false if an existing one was updated.
Throws
SecurityException if you are not allowed to add the given permission name.

public abstract boolean addPermissionAsync (PermissionInfo info)

Added in API level 8

Like addPermission(PermissionInfo) but asynchronously persists the package manager state after returning from the call, allowing it to return quicker and batch a series of adds at the expense of no guarantee the added permission will be retained if the device is rebooted before it is written.

public abstract void addPreferredActivity (IntentFilter filter, int match, ComponentName[] set, ComponentName activity)

Added in API level 1

This method was deprecated in API level 8.
This is a protected API that should not have been available to third party applications. It is the platform's responsibility for assigning preferred activities and this cannot be directly modified. Add a new preferred activity mapping to the system. This will be used to automatically select the given activity component when Context.startActivity() finds multiple matching activities and also matches the given filter.

Parameters
filter The set of intents under which this activity will be made preferred.
match The IntentFilter match category that this preference applies to.
set The set of activities that the user was picking from when this preference was made.
activity The component name of the activity that is to be preferred.

public abstract String[] canonicalToCurrentPackageNames (String[] names)

Added in API level 8

Map from a packages canonical name to the current name in use on the device.

Parameters
names Array of new names to be mapped.
Returns

public abstract int checkPermission (String permName, String pkgName)

Added in API level 1

Check whether a particular package has been granted a particular permission.

Parameters
permName The name of the permission you are checking for,
pkgName The name of the package you are checking against.
Returns
  • If the package has the permission, PERMISSION_GRANTED is returned. If it does not have the permission, PERMISSION_DENIED is returned.

public abstract int checkSignatures (int uid1, int uid2)

Added in API level 5

Like checkSignatures(String, String), but takes UIDs of the two packages to be checked. This can be useful, for example, when doing the check in an IPC, where the UID is the only identity available. It is functionally identical to determining the package associated with the UIDs and checking their signatures.

Parameters
uid1 First UID whose signature will be compared.
uid2 Second UID whose signature will be compared.
Returns

public abstract int checkSignatures (String pkg1, String pkg2)

Added in API level 1

Compare the signatures of two packages to determine if the same signature appears in both of them. If they do contain the same signature, then they are allowed special privileges when working with each other: they can share the same user-id, run instrumentation against each other, etc.

Parameters
pkg1 First package name whose signature will be compared.
pkg2 Second package name whose signature will be compared.
Returns

public abstract void clearPackagePreferredActivities (String packageName)

Added in API level 1

Remove all preferred activity mappings, previously added with addPreferredActivity(IntentFilter, int, ComponentName[], ComponentName), from the system whose activities are implemented in the given package name. An application can only clear its own package(s).

Parameters
packageName The name of the package whose preferred activity mappings are to be removed.

public abstract String[] currentToCanonicalPackageNames (String[] names)

Added in API level 8

Map from the current package names in use on the device to whatever the current canonical name of that package is.

Parameters
names Array of current names to be mapped.
Returns
  • Returns an array of the same size as the original, containing the canonical name for each package.

public abstract void extendVerificationTimeout (int id, int verificationCodeAtTimeout, long millisecondsToDelay)

Added in API level 17

Allows a package listening to the package verification broadcast to extend the default timeout for a response and declare what action to perform after the timeout occurs. The response must include the verificationCodeAtTimeout which is one of VERIFICATION_ALLOW or VERIFICATION_REJECT. This method may only be called once per package id. Additional calls will have no effect.

Parameters
id pending package identifier as passed via the EXTRA_VERIFICATION_ID Intent extra.
verificationCodeAtTimeout either VERIFICATION_ALLOW or VERIFICATION_REJECT. If verificationCodeAtTimeout is neither VERIFICATION_ALLOW or VERIFICATION_REJECT, then verificationCodeAtTimeout will default to VERIFICATION_REJECT.
millisecondsToDelay the amount of time requested for the timeout. Must be positive and less than MAXIMUM_VERIFICATION_TIMEOUT. If millisecondsToDelay is out of bounds, millisecondsToDelay will be set to the closest in bounds value; namely, 0 or MAXIMUM_VERIFICATION_TIMEOUT.
Throws
SecurityException if the caller does not have the PACKAGE_VERIFICATION_AGENT permission.
