We can't know without seeing your code. Have you tried debbuging your app? It would help if you shared the debug log aswell as the code.

Answer 2

Amar Murtaza link your code or screenshot of error, try to figure out your log report(search that error you can probably find the solution).

I think you are probably facing NullpointerExeption, if that's the case then you probably forget the Initialization process of your EditText or something.
