Question

What is the best way to debug an android application?
Every once in a while the application crashes, an it says application has stopped unexpectedly, it never says why it crashes, or where in my code, what’s the bet way to find the reason for crashes, and exceptions?

Answer 1

there are several ways to do that, activate the LogCat and you will see there detailed info about what happens with your App.

or you will implement an error Handling sending the Exception info to a Toast

 try {
    ...
    your code
    ...
 } catch (IOException e) { 
     Toast.makeText(getApplicationContext(), "Exception Info " +     e.getCause(),Toast.LENGTH_LONG).show();
    e.printStackTrace();
 }
