Constants

public static final int FLAG_ALLOW_BACKUP

Added in API level 8

Value for flags: set to false if the application does not wish to permit any OS-driven backups of its data; true otherwise.

Comes from the android:allowBackup attribute of the <application> tag.

Constant Value: 32768 (0x00008000)

public static final int FLAG_ALLOW_CLEAR_USER_DATA

Added in API level 1

Value for flags: default value for the corresponding ActivityInfo flag. Comes from android:allowClearUserData of the <application> tag.

Constant Value: 64 (0x00000040)

public static final int FLAG_ALLOW_TASK_REPARENTING

Added in API level 1

Value for flags: default value for the corresponding ActivityInfo flag. Comes from android:allowTaskReparenting of the <application> tag.

Constant Value: 32 (0x00000020)

public static final int FLAG_DEBUGGABLE

Added in API level 1

Value for flags: set to true if this application would like to allow debugging of its code, even when installed on a non-development system. Comes from android:debuggable of the <application> tag.

Constant Value: 2 (0x00000002)

public static final int FLAG_EXTERNAL_STORAGE

Added in API level 8

Value for flags: Set to true if the application is currently installed on external/removable/unprotected storage. Such applications may not be available if their storage is not currently mounted. When the storage it is on is not available, it will look like the application has been uninstalled (its .apk is no longer available) but its persistent data is not removed.

Constant Value: 262144 (0x00040000)

public static final int FLAG_FACTORY_TEST

Added in API level 1

Value for flags: set to true if this application holds the FACTORY_TEST permission and the device is running in factory test mode.

Constant Value: 16 (0x00000010)

public static final int FLAG_HAS_CODE

Added in API level 1

Value for flags: set to true if this application has code associated with it. Comes from android:hasCode of the <application> tag.

Constant Value: 4 (0x00000004)

public static final int FLAG_INSTALLED

Added in API level 17

Value for flags: true if the application is currently installed for the calling user.

Constant Value: 8388608 (0x00800000)

public static final int FLAG_IS_DATA_ONLY

Added in API level 17

Value for flags: true if the application only has its data installed; the application package itself does not currently exist on the device.

Constant Value: 16777216 (0x01000000)

public static final int FLAG_KILL_AFTER_RESTORE

Added in API level 8

Value for flags: set to false if the application must be kept in memory following a full-system restore operation; true otherwise. Ordinarily, during a full system restore operation each application is shut down following execution of its agent's onRestore() method. Setting this attribute to false prevents this. Most applications will not need to set this attribute.

If android:allowBackup is set to false or no android:backupAgent is specified, this flag will be ignored.

Comes from the android:killAfterRestore attribute of the <application> tag.

Constant Value: 65536 (0x00010000)

public static final int FLAG_LARGE_HEAP

Added in API level 11

Value for flags: true when the application has requested a large heap for its processes. Corresponds to android:largeHeap.

Constant Value: 1048576 (0x00100000)

public static final int FLAG_PERSISTENT

Added in API level 1

Value for flags: set to true if this application is persistent. Comes from android:persistent of the <application> tag.

Constant Value: 8 (0x00000008)

public static final int FLAG_RESIZEABLE_FOR_SCREENS

Added in API level 4

Value for flags: true when the application knows how to adjust its UI for different screen sizes. Corresponds to android:resizeable.

Constant Value: 4096 (0x00001000)

public static final int FLAG_RESTORE_ANY_VERSION

Added in API level 8

Value for flags: Set to true if the application's backup agent claims to be able to handle restore data even "from the future," i.e. from versions of the application with a versionCode greater than the one currently installed on the device. Use with caution! By default this attribute is false and the Backup Manager will ensure that data from "future" versions of the application are never supplied during a restore operation.

If android:allowBackup is set to false or no android:backupAgent is specified, this flag will be ignored.

Comes from the android:restoreAnyVersion attribute of the <application> tag.

Constant Value: 131072 (0x00020000)

public static final int FLAG_STOPPED

Added in API level 12

Value for flags: true if this application's package is in the stopped state.

Constant Value: 2097152 (0x00200000)
