Outgoing call receiver error

Question

I have mistake my code. when I enter "1234", code is running but I enter another number e.g. "2525" stopped my application.

String phoneNumber = getResultData();
    if (phoneNumber == null) {            
        phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
    }
   if(phoneNumber.equals("1234")){ // DialedNumber checking.            
        setResultData(null);
        Intent i=new Intent(context, MainActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        i.setAction(Intent.ACTION_MAIN);
        context.startActivity(i);

    } else {
        phoneNumber = getResultData();
    }
