Title Body

I was just wondering if it is possible to register a broadcast receiver that detects Screen ON/OFF in the application manifest. The reason why I don't like the programmable method is that it requires the app to be running in order to detect such a thing, while: "Applications with Broadcast Receivers registered in the manifest don’t have to be running when the Intent is broadcast for the receivers to execute" (source: Professional Android 2 Application Development book) My app is actually a lockscreen app which by using the programmable way needs to be running all the time :S Is there a way around it? I'm trying the following in the manifest: <receiver android:name=".MyBroadCastReciever"> <intent-filter> <action android:name="android.intent.action.SCREEN_OFF"/> <action android:name="android.intent.action.SCREEN_ON"/> </intent-filter> </receiver> and simple MyBroadCastReciever class: public class MyBroadCastReciever extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) { Log.i("Check","Screen went OFF"); Toast.makeText(context, "screen OFF",Toast.LENGTH_LONG).show(); } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) { Log.i("Check","Screen went ON"); Toast.makeText(context, "screen ON",Toast.LENGTH_LONG).show(); } } }
