Base class for implementing a device administration component. This class provides a convenience for interpreting the raw intent actions that are sent by the system.
The callback methods, like the base
 BroadcastReceiver.onReceive()
 method, happen on the main thread of the process.  Thus long running
 operations must be done on another thread.  Note that because a receiver
 is done once returning from its receive function, such long-running operations
 should probably be done in a Service.
 
When publishing your DeviceAdmin subclass as a receiver, it must
 handle ACTION_DEVICE_ADMIN_ENABLED and require the
 Manifest.permission.BIND_DEVICE_ADMIN permission.  A typical
 manifest entry would look like:
<receiver android:name=".app.DeviceAdminSample$DeviceAdminSampleReceiver"
        android:label="@string/sample_device_admin"
        android:description="@string/sample_device_admin_description"
        android:permission="android.permission.BIND_DEVICE_ADMIN">
    <meta-data android:name="android.app.device_admin"
               android:resource="@xml/device_admin_sample" />
    <intent-filter>
        <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
    </intent-filter>
</receiver>
<receiver android:name=".app.DeviceAdminSample$DeviceAdminSampleReceiver2"
    android:label="@string/sample_device_admin2"
    android:description="@string/sample_device_admin_description2"
    android:permission="android.permission.BIND_DEVICE_ADMIN">
    <meta-data android:name="android.app.device_admin"
        android:resource="@xml/device_admin_sample" />
    <intent-filter>
        <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
    </intent-filter>
</receiver>The meta-data referenced here provides addition information specific
 to the device administrator, as parsed by the DeviceAdminInfo class.
 A typical file would be:
<device-admin xmlns:android="http://schemas.android.com/apk/res/android">
    <uses-policies>
        <limit-password />
        <watch-login />
        <reset-password />
        <force-lock />
        <wipe-data />
        <expire-password />
        <encrypted-storage />
        <disable-camera />
        <disable-keyguard-features />

ACTION_CHOOSE_PRIVATE_KEY_ALIAS
public static final String ACTION_CHOOSE_PRIVATE_KEY_ALIAS
Broadcast action: notify that some app is attempting to choose a KeyChain key.
See also:
Constant Value: "android.app.action.CHOOSE_PRIVATE_KEY_ALIAS"
ACTION_DEVICE_ADMIN_DISABLED
public static final String ACTION_DEVICE_ADMIN_DISABLED
Action sent to a device administrator when the user has disabled
 it.  Upon return, the application no longer has access to the
 protected device policy manager APIs.  You will generally
 handle this in DeviceAdminReceiver.onDisabled(Context, Intent).  Note
 that this action will be
 sent the receiver regardless of whether it is explicitly listed in
 its intent filter.
Constant Value: "android.app.action.DEVICE_ADMIN_DISABLED"
ACTION_DEVICE_ADMIN_DISABLE_REQUESTED
public static final String ACTION_DEVICE_ADMIN_DISABLE_REQUESTED
Action sent to a device administrator when the user has requested to
 disable it, but before this has actually been done.  This gives you
 a chance to supply a message to the user about the impact of
 disabling your admin, by setting the extra field
 EXTRA_DISABLE_WARNING in the result Intent.  If not set,
 no warning will be displayed.  If set, the given text will be shown
 to the user before they disable your admin.
Constant Value: "android.app.action.DEVICE_ADMIN_DISABLE_REQUESTED"
ACTION_DEVICE_ADMIN_ENABLED
public static final String ACTION_DEVICE_ADMIN_ENABLED
This is the primary action that a device administrator must implement to be
 allowed to manage a device.  This will be set to the receiver
 when the user enables it for administration.  You will generally
 handle this in DeviceAdminReceiver.onEnabled(Context, Intent).  To be
 supported, the receiver must also require the
 Manifest.permission.BIND_DEVICE_ADMIN permission so
 that other applications can not abuse it.
Constant Value: "android.app.action.DEVICE_ADMIN_ENABLED"
ACTION_LOCK_TASK_ENTERING
public static final String ACTION_LOCK_TASK_ENTERING
Action sent to a device administrator to notify that the device is entering
 lock task mode.  The extra EXTRA_LOCK_TASK_PACKAGE
 will describe the package using lock task mode.
 
The calling device admin must be the device owner or profile owner to receive this broadcast.
Constant Value: "android.app.action.LOCK_TASK_ENTERING"
ACTION_LOCK_TASK_EXITING
public static final String ACTION_LOCK_TASK_EXITING
Action sent to a device administrator to notify that the device is exiting lock task mode.
The calling device admin must be the device owner or profile owner to receive this broadcast.
Constant Value: "android.app.action.LOCK_TASK_EXITING"
ACTION_NETWORK_LOGS_AVAILABLE
public static final String ACTION_NETWORK_LOGS_AVAILABLE
Broadcast action: notify that a new batch of network logs is ready to be collected.
See also:
Constant Value: "android.app.action.NETWORK_LOGS_AVAILABLE"
ACTION_PASSWORD_CHANGED
public static final String ACTION_PASSWORD_CHANGED
Action sent to a device administrator when the user has changed the password of their device
 or profile challenge.  You can at this point check the characteristics
 of the new password with DevicePolicyManager.isActivePasswordSufficient().
 You will generally
 handle this in DeviceAdminReceiver.onPasswordChanged(Context, Intent, UserHandle).
 
The calling device admin must have requested
 DeviceAdminInfo.USES_POLICY_LIMIT_PASSWORD to receive
 this broadcast.
Constant Value: "android.app.action.ACTION_PASSWORD_CHANGED"
ACTION_PASSWORD_EXPIRING
public static final String ACTION_PASSWORD_EXPIRING
Action periodically sent to a device administrator when the device or profile challenge
 password is expiring.  You will generally
 handle this in DeviceAdminReceiver.onPasswordExpiring(Context, Intent, UserHandle).
 
The calling device admin must have requested
 DeviceAdminInfo.USES_POLICY_EXPIRE_PASSWORD to receive
 this broadcast.
Constant Value: "android.app.action.ACTION_PASSWORD_EXPIRING"
ACTION_PASSWORD_FAILED
public static final String ACTION_PASSWORD_FAILED
Action sent to a device administrator when the user has entered an incorrect device
 or profile challenge password.  You can at this point check the
 number of failed password attempts there have been with
 DevicePolicyManager.getCurrentFailedPasswordAttempts().  You will generally
 handle this in DeviceAdminReceiver.onPasswordFailed(Context, Intent, UserHandle).
 
The calling device admin must have requested
 DeviceAdminInfo.USES_POLICY_WATCH_LOGIN to receive
 this broadcast.
Constant Value: "android.app.action.ACTION_PASSWORD_FAILED"
ACTION_PASSWORD_SUCCEEDED
public static final String ACTION_PASSWORD_SUCCEEDED
Action sent to a device administrator when the user has successfully entered their device
 or profile challenge password, after failing one or more times.  You will generally
 handle this in DeviceAdminReceiver.onPasswordSucceeded(Context, Intent, UserHandle).
 
The calling device admin must have requested
 DeviceAdminInfo.USES_POLICY_WATCH_LOGIN to receive
 this broadcast.
Constant Value: "android.app.action.ACTION_PASSWORD_SUCCEEDED"
ACTION_PROFILE_PROVISIONING_COMPLETE
public static final String ACTION_PROFILE_PROVISIONING_COMPLETE
Broadcast Action: This broadcast is sent to indicate that provisioning of a managed profile or managed device has completed successfully.
The broadcast is limited to the profile that will be managed by the application that
 requested provisioning. In the device owner case the profile is the primary user.
 The broadcast will also be limited to the DeviceAdminReceiver component
 specified in the original intent or NFC bump that started the provisioning process
 (see DevicePolicyManager.ACTION_PROVISION_MANAGED_PROFILE).
 
A device admin application which listens to this intent can find out if the device was
 provisioned for the device owner or profile owner case by calling respectively
 DevicePolicyManager.isDeviceOwnerApp(String) and
 DevicePolicyManager.isProfileOwnerApp(String). You will generally handle
 this in DeviceAdminReceiver.onProfileProvisioningComplete.
 
The intent for this action may include the following extras:
- DevicePolicyManager.EXTRA_PROVISIONING_ADMIN_EXTRAS_BUNDLE- Constant Value: "android.app.action.PROFILE_PROVISIONING_COMPLETE" 
ACTION_SECURITY_LOGS_AVAILABLE
public static final String ACTION_SECURITY_LOGS_AVAILABLE
Broadcast action: notify that a new batch of security logs is ready to be collected.
Constant Value: "android.app.action.SECURITY_LOGS_AVAILABLE"
BUGREPORT_FAILURE_FAILED_COMPLETING
public static final int BUGREPORT_FAILURE_FAILED_COMPLETING
Bugreport completion process failed.
If this error code is received, the requesting of bugreport can be retried.
Constant Value: 0 (0x00000000)
BUGREPORT_FAILURE_FILE_NO_LONGER_AVAILABLE
public static final int BUGREPORT_FAILURE_FILE_NO_LONGER_AVAILABLE
Bugreport has been created, but is no longer available for collection.
This error likely occurs because the user of the device hasn't consented to share the bugreport for a long period after its creation.
If this error code is received, the requesting of bugreport can be retried.
Constant Value: 1 (0x00000001)
DEVICE_ADMIN_META_DATA
public static final String DEVICE_ADMIN_META_DATA
Name under which a DevicePolicy component publishes information about itself. This meta-data must reference an XML resource containing a device-admin tag.
Constant Value: "android.app.device_admin"
EXTRA_DISABLE_WARNING
public static final String EXTRA_DISABLE_WARNING
A CharSequence that can be shown to the user informing them of the impact of disabling your admin.
See also:
Constant Value: "android.app.extra.DISABLE_WARNING"
EXTRA_LOCK_TASK_PACKAGE
public static final String EXTRA_LOCK_TASK_PACKAGE
A string containing the name of the package entering lock task mode.
See also:
Constant Value: "android.app.extra.LOCK_TASK_PACKAGE"
EXTRA_TRANSFER_OWNERSHIP_ADMIN_EXTRAS_BUNDLE
public static final String EXTRA_TRANSFER_OWNERSHIP_ADMIN_EXTRAS_BUNDLE
A Parcelable extra of type PersistableBundle that
 allows a mobile device management application to pass data to the management application
 instance after owner transfer.
 
If the transfer is successful, the new owner receives the data in
 DeviceAdminReceiver.onTransferOwnershipComplete(Context, PersistableBundle).

onComplianceAcknowledgementRequired
public void onComplianceAcknowledgementRequired (Context context, Intent intent)
Called to notify a profile owner of an organization-owned device that it needs to acknowledge device compliance to allow the user to turn the profile off if needed according to the maximum profile time off policy. Default implementation acknowledges compliance immediately. DPC may prefer to override this implementation to delay acknowledgement until a successful policy sync. Until compliance is acknowledged the user is still free to turn the profile off, but the timer won't be reset, so personal apps will be suspended sooner. This callback is delivered using a foreground broadcast and should be handled quickly.

onProfileProvisioningComplete
public void onProfileProvisioningComplete (Context context, Intent intent)
Called when provisioning of a managed profile or managed device has completed successfully.
 As a prerequisite for the execution of this callback the DeviceAdminReceiver has
 to declare an intent filter for ACTION_PROFILE_PROVISIONING_COMPLETE.
 Its component must also be specified in the DevicePolicyManager.EXTRA_DEVICE_ADMIN
 of the DevicePolicyManager.ACTION_PROVISION_MANAGED_PROFILE intent that started the
 managed provisioning.
 
When provisioning of a managed profile is complete, the managed profile is hidden until
 the profile owner calls DevicePolicyManager.setProfileEnabled(ComponentName admin).
 Typically a profile owner will enable the profile when it has finished any additional setup
 such as adding an account by using the AccountManager and calling APIs to bring the
 profile into the desired state.
 
Note that provisioning completes without waiting for any server interactions, so the profile owner needs to wait for data to be available if required (e.g. Android device IDs or other data that is set as a result of server interactions).
From version Build.VERSION_CODES.O, when managed provisioning has
 completed, along with this callback the activity intent
 DevicePolicyManager.ACTION_PROVISIONING_SUCCESSFUL will also be sent to the same
 application.
 
The Intent may include any of the extras specified for
 ACTION_PROFILE_PROVISIONING_COMPLETE.
| Parameters | |
