Estou tentando desenvolver um aplicativo no Android que bloqueia um sms recebido. Eu defini a prioridade, mas não está bloqueando as mensagens recebidas. Eu tenho usadothis.abortBroadcast() também, mas sem resultado.

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.gsm.SmsMessage;

import android.widget.Toast;

@SuppressWarnings("deprecation")
public class SmsReceiver extends BroadcastReceiver
{

@Override
public void onReceive(Context context, Intent intent) 
{
this.abortBroadcast();  

    Bundle bundle = intent.getExtras();        
    SmsMessage[] msgs = null;
    String str = "";

    if (bundle != null)
    {


        Object[] pdus = (Object[]) bundle.get("pdus");
        msgs = new SmsMessage[pdus.length];            
        for (int i=0; i<msgs.length; i++){
            msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);                
            str += "SMS from " + msgs[i].getOriginatingAddress();                     
            str += " :";
            str += msgs[i].getMessageBody().toString();
            str += "\n";        

}


}
}
}

e o arquivo de manifesto é assim
