android.intent.action.SCREEN_ON doesn't work as a receiver intent filter
I'm trying to get a BroadcastReceiver invoked when the screen is turned on. In my AndroidManifest.xml I have specified :
<receiver android:name="IntentReceiver">
<intent-filter>
<action android:name="android.intent.action.SCREEN_ON"></action>
</intent-filter>
</receiver>
However it seems the receiver is never invoked (breakpoints don't fire, log statements ignored). I've swapped out SCREEN_ON for BOOT_COMPLETED for a test, and this does get invoked.
This is in a 1.6 (SDK level 4) project.
A Google Code Search revealed this, I download开发者_如何转开发ed the project and synced it, converted it to work with latest tools, but it too is not able to intercept that event.

Is this perhaps no longer supported?
Previously I have been able to intercept this event successfully with a call to Context.registerReceiver() like so
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// ...
}
}, new IntentFilter(Intent.ACTION_SCREEN_ON));
However this was performed by a long-living Service. Following sage advice from CommonsWare I have elected to try to remove the long-living Service and use different techniques. But I still need to detect the screen off and on events.

Actually, I believe my advice was more of a light blue... :-)

There are certain events that Android does not want to start up new processes for, so the device does not get too slow from all sorts of stuff all having to run at once. ACTION_SCREEN_ON
is one of those. See this previous question for light blue advice on that topic.
So, you need to ask yourself, "Self, do I really need to get control on those events?". The core Android team would like it if your answer was "no".
This is the best example I've found http://androidexample.com/Screen_Wake_Sleep_Event_Listner_Service_-_Android_Example/index.php?view=article_discription&aid=91&aaid=115
Actullay i was faceing this issue but i resolve it succeessfully
1) start service from your main activity
Intent i = new Intent(MainActivity.this, UpdateService.class);
startService(i);
2) register reciver in service class.
@Override
public void onCreate() {
super.onCreate();
// REGISTER RECEIVER THAT HANDLES SCREEN ON AND SCREEN OFF LOGIC
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
BroadcastReceiver mReceiver = new ScreenReciever();
registerReceiver(mReceiver, filter);
}
3) Done
