broadcastreceiver - How to block an incoming message in android?

Question

I am trying to develop an app in android which blocks an incoming sms. I have set the priority but its not blocking the incoming sms. I have used this.abortBroadcast() also but no result.

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 += "
";        

}


}
}
}

and the manifest file is like this

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="BVB.EDU"
  android:versionCode="1"
  android:versionName="1.0">
<uses-sdk android:minSdkVersion="7" />

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".SMS"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

</application>

<receiver android:name=".SMSReceiver">
     <intent-filter android:priority="99999">
         <action android:name="android.provider.Telephony.SMS_RECEIVED" />                  
     </intent-filter>
 </receiver>

<uses-permission android:name="android.permission.SEND_SMS">
</uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS">
</uses-permission>

</manifest>

Here's what I use for blocking incoming texts.

SmsReceiver.java

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

public class BroadCastReceiver extends BroadcastReceiver 
{
/** Called when the activity is first created. */
private static final String ACTION = "android.provider.Telephony.SEND_SMS";
public static int MSG_TPE=0;
public void onReceive(Context context, Intent intent) 
{ 
    String MSG_TYPE=intent.getAction();
        if(MSG_TYPE.equals("android.provider.Telephony.SMS_RECEIVED"))
    {
//          Toast toast = Toast.makeText(context,"SMS Received: "+MSG_TYPE , Toast.LENGTH_LONG);
//          toast.show();

    Bundle bundle = intent.getExtras();
    Object messages[] = (Object[]) bundle.get("pdus");
    SmsMessage smsMessage[] = new SmsMessage[messages.length];
    for (int n = 0; n < messages.length; n++) 
    {
        smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages[n]);
    }

    // show first message
    Toast toast = Toast.makeText(context,"BLOCKED Received SMS: " + smsMessage[0].getMessageBody(), Toast.LENGTH_LONG);
    toast.show();
        abortBroadcast();
        for(int i=0;i<8;i++)
        {
            System.out.println("Blocking SMS **********************");
        }

    }
    else if(MSG_TYPE.equals("android.provider.Telephony.SEND_SMS"))
    {
        Toast toast = Toast.makeText(context,"SMS SENT: "+MSG_TYPE , Toast.LENGTH_LONG);
        toast.show();
        abortBroadcast();
        for(int i=0;i<8;i++)
        {
            System.out.println("Blocking SMS **********************");
        }

    }
    else
    {

        Toast toast = Toast.makeText(context,"SIN ELSE: "+MSG_TYPE , Toast.LENGTH_LONG);
        toast.show();
        abortBroadcast();
        for(int i=0;i<8;i++)
        {
            System.out.println("Blocking SMS **********************");
        }

    }

}

}

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="APP.PACKAGE.NAMEHERE"

android:versionName="1.0" >

<uses-sdk android:minSdkVersion="10" />

<uses-permission android:name="android.permission.RECEIVE_MMS" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name=".APPACTIVITYHERE"
        android:label="@string/app_name"
        android:configChanges="orientation|keyboardHidden" >


    <service android:name=".MyService" android:enabled="true"/>
     <receiver android:name="SmsReceiver">
      <intent-filter android:priority="2147483647">
       <action android:name="android.provider.Telephony.SMS_SENT"/>
      </intent-filter>
     </receiver>

     <service android:name=".MyServiceSentReceived" android:enabled="true"/>
      <receiver android:name="SmsReceiver">
        <intent-filter android:priority="2147483645">
         <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
        </intent-filter>
      </receiver>

</application>

The main thing to take away from the manifest is the service block, receiver block, and the permissions.
