Hi, i am developing an android application and i need help to solve my
problem on my application.
My application is consist of 2 activity,  main.java and
CobaGesture.java.

Main,java has a start button that run startActivity(new
Intent(main.this, CobaGesture.class));
CobaGesture.java has a back button that run finish();
startActivity(new Intent(CobaGesture.this, main.class));

When the app running, i press the start button the activity changed to
CobaGesture, and when i press back button in CobaGesture the activity
back to main. But, when i press start again the app is forced close
and here's logcat of the error:

I am not getting why are you starting activity  main in your cobaGesture on back button click.
On your back button click there at cobaGesture, you will automatically be switched to your previous activity (if you haven't finished it), you don't have to do anything there.
