Foreground service class code for calling the shutDown broadcast receiver.
public class SmsForegroundService extends Service{
private BroadcastReceiver receiver;
public static class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// do something
Log.d(TAG, "onReceive: "+intent.getAction());
if (intent.getAction().equals(Intent.ACTION_SHUTDOWN)) {
Log.d(TAG, "onReceive: ScreenOff");
}
}
// constructor
public MyReceiver(){
}
}
@Override
public void onCreate() {
super.onCreate();
Log.d(TAG, "onCreate: ");
IntentFilter filter = new IntentFilter(Intent.ACTION_SHUTDOWN);
receiver = new MyReceiver();
this.registerReceiver(receiver,filter);
}
@Override
public void onDestroy() {
Log.d(TAG, "onDestroy: service destroyed");
super.onDestroy();
this.unregisterReceiver(receiver);
}
//
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.d(TAG ,"service running");
final String CHANNEL_ID = "foreground Service ID";
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(
CHANNEL_ID,
CHANNEL_ID,
NotificationManager.IMPORTANCE_HIGH
);
getSystemService(NotificationManager.class).createNotificationChannel(channel);
Notification.Builder notification = new Notification.Builder(this,CHANNEL_ID)
.setContentText("Service is running")
.setContentTitle("Service is enabled")
.setSmallIcon(R.drawable.ic_launcher_background);
startForeground(1001, notification.build());
}
return super.onStartCommand(intent, flags, startId);
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
Log.d(TAG, "onBind: ");
return null;
}
}
AndroidManifest file, here I added only the permission for Foreground services, I think there is no other permission is required for action_shutdown in manifest for versions greater than Oreo.

MainActivity I have called the service class inside on Create method MainActivity class.
public class MainActivity extends AppCompatActivity {
@RequiresApi(api = Build.VERSION_CODES.O)
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(!foregroundServiceRunning())
{
Intent serviceIntent = new Intent(this, SmsForegroundService.class);
ContextCompat.startForegroundService(this,serviceIntent);
}
}
public boolean foregroundServiceRunning(){
ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
for(ActivityManager.RunningServiceInfo serviceInfo: activityManager.getRunningServices(Integer.MAX_VALUE)){
if(SmsForegroundService.class.getName().equals(serviceInfo.service.getClassName())){
return true;
}
}
return false;
}
}
