import android.util.Log;

public class GucOutgoingCallReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
        Bundle bundle = intent.getExtras();
        if (null == bundle)
            return;
        // String
        // outgoingNumber=intent.getStringExtra(Intent.ACTION_NEW_OUTGOING_CALL);
        String phoneNubmer = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);

        startActivity(dialIntent);
        
//        TelephonyManager tm = (TelephonyManager) this.getSystemService(TELEPHONY_SERVICE);
//        PhoneStateListener phoneListener=new PhoneStateListener();
//        //phoneListener.onCallStateChanged(state, incomingNumber)
//        tm.listen(phoneListener, phoneListener.LISTEN_CALL_STATE);
