How to prevent outgoing call in android with a service?

I wanna make a service that when it is active and the user presses the call button, whether in the OS phone app or in the contacts, it prevents outgoing call. I mean instead of running android calling service, i want my service to be run. Is there any way to do so? I am really beginner in android programming and i don't really know a lot about android services. I'll appreciate you to help me. Thanks a lot.

You have to use BroadcastReceiver for this.

in manifest you have to write

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

<receiver android:name=".OutGoingCallListener">
       <intent-filter android:priority="0">
           <action android:name="android.intent.action.NEW_OUTGOING_CALL"/>
       </intent-filter>

   </receiver>

And in class which extends from BroadcastReceiver you have to write

public class OutGoingCallListener extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    String number=intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER).toString();

       //if u want to block particular call then check number or else block all call in thid code

        setResultData(null);//Canceling call operation 
        Toast.makeText(context, "This call is not Allowed", Toast.LENGTH_LONG).show();


} }
