/**
|
|
* Base class for a service that device owner/profile owners can optionally have.
|
|
*
|
|
* <p>The system searches for it with an intent filter with the
|
|
* {@link DevicePolicyManager#ACTION_DEVICE_ADMIN_SERVICE} action, and tries to keep a bound
|
|
* connection as long as the hosting user is running, so that the device/profile owner is always
|
|
* considered to be in the foreground. This is useful to receive implicit broadcasts that
|
|
* can no longer be received by manifest receivers by apps targeting Android version
|
|
* {@link android.os.Build.VERSION_CODES#O}. Device/profile owners can use a runtime-registered
|
|
* broadcast receiver instead, and have a {@link DeviceAdminService} so that the process is always
|
|
* running.
|
|
*
|
|
* <p>Device/profile owners can use
|
|
* {@link android.content.pm.PackageManager#setComponentEnabledSetting(ComponentName, int, int)}
|
|
* to disable/enable its own service. For example, when a device/profile owner no longer needs
|
|
* to be in the foreground, it can (and should) disable its service.
|
|
*
|
|
* <p>The service must be protected with the permission
|
|
* {@link android.Manifest.permission#BIND_DEVICE_ADMIN}. Otherwise the system would ignore it.
|
|
*
|
|
* <p>When the owner process crashes, the service will be re-bound automatically after a
|
|
* back-off.
|
|
*
|
|
* <p>Note the process may still be killed if the system is under heavy memory pressure, in which
|
|
* case the process will be re-started later.
|
|
*
|
|
* <p>Starting from Android {@link android.os.Build.VERSION_CODES#UPSIDE_DOWN_CAKE},
|
|
* non-DPC admins can also optionally implement this service using the details
|
|
* mentioned above to ensure they receive policy update broadcasts
|
|
* (see {@link PolicyUpdateReceiver}).
