/**
 * Base class for a service that device owner/profile owners can optionally have.
 *
 * 

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. * *

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. * *

The service must be protected with the permission * {@link android.Manifest.permission#BIND_DEVICE_ADMIN}. Otherwise the system would ignore it. * *

When the owner process crashes, the service will be re-bound automatically after a * back-off. * *

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. */ public class DeviceAdminService extends Service { private final IDeviceAdminServiceImpl mImpl; public DeviceAdminService() { mImpl = new IDeviceAdminServiceImpl(); } @Override public final IBinder onBind(Intent intent) { return mImpl.asBinder(); } private class IDeviceAdminServiceImpl extends IDeviceAdminService.Stub { } // So far, we have no methods in this class. }
