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
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>
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 />
</uses-policies>
</device-admin>

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 onDisabled(Context, Intent). Note
that this action will be
sent the receiver regardless of whether it is explicitly listed in
its intent filter.
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.
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 onEnabled(Context, Intent). To be
supported, the receiver must also require the
BIND_DEVICE_ADMIN permission so
that other applications can not abuse it.
Action sent to a device administrator to notify that the device is entering
lock task mode from an authorized package. The extra EXTRA_LOCK_TASK_PACKAGE
will describe the authorized package using lock task mode.
The calling device admin must be the device owner or profile owner to receive this broadcast.
Action sent to a device administrator to notify that the device is exiting lock task mode from an authorized package.
The calling device admin must be the device owner or profile owner to receive this broadcast.
Action sent to a device administrator when the user has changed the
password of their device. You can at this point check the characteristics
of the new password with DevicePolicyManager.isActivePasswordSufficient().
You will generally
handle this in onPasswordChanged(Context, Intent).
The calling device admin must have requested
USES_POLICY_LIMIT_PASSWORD to receive
this broadcast.
Action periodically sent to a device administrator when the device password is expiring.
The calling device admin must have requested
USES_POLICY_EXPIRE_PASSWORD to receive
this broadcast.
Action sent to a device administrator when the user has failed at
attempted to enter the 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 onPasswordFailed(Context, Intent).
The calling device admin must have requested
USES_POLICY_WATCH_LOGIN to receive
this broadcast.
Action sent to a device administrator when the user has successfully entered their password, after failing one or more times.
The calling device admin must have requested
USES_POLICY_WATCH_LOGIN to receive
this broadcast.
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
isDeviceOwnerApp(String) and
isProfileOwnerApp(String).
Input: Nothing.
Output: Nothing
Name under which a DevicePolicy component publishes information about itself. This meta-data must reference an XML resource containing a device-admin tag. XXX TO DO: describe syntax.
A CharSequence that can be shown to the user informing them of the impact of disabling your admin.
A string containing the name of the package entering lock task mode.
Retrieve the DevicePolicyManager interface for this administrator to work with the system.
Retrieve the ComponentName describing who this device administrator is, for
use in DevicePolicyManager APIs that require the administrator to
identify itself.
Called when the user has asked to disable the administrator, as a result of
receiving ACTION_DEVICE_ADMIN_DISABLE_REQUESTED, giving you
a chance to present a warning message to them. The message is returned
as the result; if null is returned (the default implementation), no
message will be displayed.

API.

Called after the administrator is first enabled, as a result of
receiving ACTION_DEVICE_ADMIN_ENABLED. At this point you
can use DevicePolicyManager to set your desired policies.
If the admin is activated by a device owner, then the intent may contain private extras that are relevant to user setup.

can use DevicePolicyManager.getCurrentFailedPasswordAttempts()
to retrieve the active password characteristics.

Called periodically when the password is about to expire or has expired. It will typically be called at these times: on device boot, once per day before the password expires, and at the time when the password expires.
If the password is not updated by the user, this method will continue to be called once per day until the password is changed or the device admin disables password expiration.
The admin will typically post a notification requesting the user to change their password
in response to this call. The actual password expiration time can be obtained by calling
getPasswordExpiration(ComponentName)
The admin should be sure to take down any notifications it posted in response to this call
when it receives onPasswordChanged(Context, Intent).

Called when provisioning of a managed profile or managed device has completed successfully.
As a prerequisit for the execution of this callback the (@link DeviceAdminReceiver} has
to declare an intent filter for ACTION_PROFILE_PROVISIONING_COMPLETE.
Its component must also be specified in the EXTRA_DEVICE_ADMIN
of the ACTION_PROVISION_MANAGED_PROFILE intent that started the
managed provisioning.
When provisioning 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).
