Receiving Sms message

I am trying to get sms from my application. I made a ReceiveSms class that extends the broadCastReceiver class. and i also override onReceive (). I added permissions and registered the receiver in the manifest. but when i send sms using DDMS my onRecieve is not called. What for? Thanks in advance. Here is my manifest and BroadCastReceiver.

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;

public class ReceiveSms extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "One Message Received", Toast.LENGTH_LONG).show();
    }

}

      

        
        
        
      

    

manifest.xml
