Screen_Off does not work in application Level ,although it is working on Activity Level.

My Problem,when Screen goes off,it must go to Login screen,below code ,successfully go to Login screen but it cause me unregistered Receive Broadcast

Manifest Level

          <receiver android:name="com.android.libray.ScreenReciver" android:enabled="true" >
         <intent-filter>
             <action android:name="android.intent.action.SCREEN_OFF"/>
                   <action android:name="android.intent.action.SCREEN_ON"/>
             </intent-filter>
      </receiver>

  IntentFilter filter =new IntentFilter(Intent.ACTION_SCREEN_OFF);

            BroadcastReceiver mReceiver=new ScreenReciver();
                registerReceiver(mReceiver, filter);

public class ScreenReciver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
         if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
                // do whatever you need to do here

             Intent myintent = new Intent(context,TimerClockActivity.class);
                myintent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
                myintent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(myintent);
                wasScreenOn = false;
             Log.v("screenoff", "Logggoff");

            } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
                // and do whatever you need to do here

            }


    }

The SCREEN_OFF Broadcast is a protected broadcast, and you will only receive it if you register dynamically through Java code in a Service or Activity or another Receiver. Registering in the manifest doesn't work for this broadcast.
