Call Control Example Issue on Emulator
I am testing call control example given on: http://prasanta-paul.blogspot.com/2010/09/call-control-in-android.html on emultaor.
Code is as below:
package com.example.callblock;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.os.RemoteException;
import android.telephony.TelephonyManager;
import android.widget.Toast;
import com.android.internal.telephony.ITelephony;
public class CallBlock extends BroadcastReceiver{
String[] blockedNumbers = {"5556"};
String incommingNumber;
Context context;
String incomingNumber;
ITelephony telephonyService;
public void onReceive(Context context, Intent intent) {
//Log.v(TAG, "Incoming Call BroadCast received...");
// Log.v(TAG, "Intent: ["+ intent.getAction() +"]");
Bundle b = intent.getExtras();
incommingNumber = b.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
Toast.makeText(context, "Phone no:"+incomingNumber, Toast.LENGTH_LONG).show();
// Additional Step
// Check whether this number matches with your defined Block List
// If yes, Reject the Call
if(incommingNumber.equals(blockedNumbers[0])){
try {
telephonyService.endCall();
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
When i tried to run this example ie make call from one emulator(5556) to the second emulator(5554). It shows Phoneno:null.
I am unable to understand the reaso开发者_JAVA技巧n for this.
