how to use the finish() method in android [closed]

Question

I am a new beginner in android, so please tell me how to finish an activity in Android. I have already done one project. In this project, the previous activity was also working. So please tell me how to finish that activity when the next activity starts briefly.

Thanks in advance

Answer 1

After I start the activity, I call the finish() method:

Intent i=new Intent(mainclass.this,nextclass.class);
startActivity(i);
finish();

Then the previous activity(mainclass) is finished.
