Android ComponentInfo и NullPointerException

Question

в применении иногда я получаю эту ошибку и после того, как след я не могу найти, Что причина этой ошибки:

    } 
} 

линия 223 является конец updateAndIntertDialog функции и ServiceDialog.java:105 звонит updateAndIntertDialog функция

Answer 1

ли Contentresolver нуль? Попробуйте в методе OnCreate вместо

contentResolver = ctx.getContentResolver(); 

вызов

contentResolver = this.getContentResolver(); 

или

contentResolver = getContentResolver();
