не в состоянии startactivity componentinfo

Question

У меня возникла ошибка, когда я нажал кнопку формы mainactivity, она перейдет к активности, но вместо этого она сработает ..... я никогда не сталкивался с этой ошибкой, прежде чем вы могли бы помочь мне.

Приложение прекращено.

здесь является Java, где ошибка происходит из

Answer 1

Кажется, что вы пропустили Компоновка тег. Используйте раскладку:

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.navigation_front); //<---here 
     ........ 
     ......... 

И выравнивать код правильно:

Answer 2

попробовать это:

Заменить это:

setContentView(navigation_front); 

С:

setContentView(R.layout.navigation_front); 

Здесь Вы забыли добавить R.layout ..Thats почему вы получаете ошибки ResourceNotFound

Надеется, что это помогает .. (:
