Android notification of screen off/on

Question

I'm looking to see if there's a system notification I can listen for to see when the screen turns off/on. Any thoughts? Something similar to when the network connects/disconnects.

Easiest way is to put this in your MyApplication.onCreate() method:

IntentFilter intentFilter = new IntentFilter(Intent.ACTION_SCREEN_ON);
intentFilter.addAction(Intent.ACTION_SCREEN_OFF);
registerReceiver(new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
            Log.d(TAG, Intent.ACTION_SCREEN_OFF);
        } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
            Log.d(TAG, Intent.ACTION_SCREEN_ON);
        }
    }
}, intentFilter);
