Just Remove finish() from Activity.

Because when you go to second activity and finish first activity, there is no any activity and stack.

So If you click back button from second activity, application will be finish if there is no Activity in stack.

You should use this Approach.

Ex.

In Activity.java

Intent first = new Intent(Activity.this,ActivityB.class);
startAcivity(first);
// Don't use finish() here.

In ActivityB.Java

Just click on built in back button.

or If you want to use your own back button.

Use finish(); in button click event.

You can use only onBackPressed();

   public void onBackPressed() {

        super.onBackPressed();
    }

Just use finish() no need for intent as A is already in stack and when you finish B, A will come to surface 

 public void onBackPressed() {

        finish(); 

     }

No need to put an intent and start a new activity that would take you to previous activity.

Just call 'finish()'

It would go back to previous activity as Android activities are stored in the activity stack

If you have other activities that are present in between the activites say if android stack is filled with Activity A>Activity C>Activity B,If you want to go to Activity A on finish of Activityy B then you have to set an intent flag like FLAG_ACTIVITY_REORDER_TO_FRONT or FLAG_ACTIVITY_PREVIOUS_IS_TOP
