public class AnsTheCallReceiver extends BroadcastReceiver {

public static final String TAG = "Andros:AnsTheCall:receiver";
public selectedTabType attentFlag = selectedTabType.TYPE_INVALID;

private Intent AnsTheCallServiceIntent = null;
public String contactName = null;
public String contactEmail = "";
public int PhoneNumberCount= 0;

@Override
public void onReceive(Context context, Intent intent) {

    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
    SharedPreferences.Editor editor = prefs.edit();
    // Check phone state
    String phone_state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
    String phoneNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
    String lastPhoneNumber = null;
    Log.i(TAG,"initialised the receiver");

    if (phone_state.equals(TelephonyManager.EXTRA_STATE_RINGING) && prefs.getBoolean("appEnabled", false)) {
        int is_starred = isStarred(context, phoneNumber);
