Сбой приложения для Android после добавления CheckBox

Question

Я создаю приложение блокировки вызовов, и когда я добавляю флажок или переключатель в свой макет, приложение начинает сбой.

Код для деятельности.

public void onCreate(Bundle savedInstanceState) { 
    //final EditText edittext = (EditText) findViewById(R.id.edittext); 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    edit=(EditText)findViewById(R.id.editText); 
    check=(CheckBox)findViewById(R.id.checkBox); 

    textview=(TextView)findViewById(R.id.textView); 
    String Number=edit.getText().toString(); 
    String checked="0"; 
    if(check.isChecked()) 
    checked="1"; 
    else 
    checked="0"; 

    Intent intent = new Intent(PrefActivity.this, PhoneReceiver.class); 
    intent.putExtra("check", checked); 
    intent.putExtra("CELL", Number); 
    PendingIntent sender= PendingIntent.getBroadcast(
      Activity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 



} 


public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    return true; 
} 

}

Answer 1

выглядит как строка кода вызывает исключение:

if(incomingNumber.contentEquals(num)) { 

incomingNumber является нулевым, и нуль не имеет метод contentEquals, поэтому он бросает исключение.

Поэтому перед отправкой необходимо передать строковое значение для ключа TelephonyManager.EXTRA_INCOMING_NUMBER.

Существует еще одна проблема в коде:

if(check=="1") 

должен измениться if("1". contentEquals(check))
