Answer 1

Try to create a method on your Activity that will call finish(). And then, call this method from within your onResponse().

Something like:

private void killActivity() {
    finish();
}

And then, call it here:

if(Boolean.parseBoolean(Flag)) {
    Intent intent=new Intent(PhoneVerificationActivity.this,ConfirmSms.class);
    intent.putExtra("PhoneNumber", Phone);
    startActivity(intent);
    killActivity(); // Here.
}

Answer 2

Check the following in your code

1.Are you extends Activity correctly?

Public class YourActivity extends Activity{
  }

2.if you extends activity correctly, Finish() will work properly.

YourActivity.this.finish();

3.if you use Dialogs, you should dismiss the Dialog before finish the activity

Dialog.dismiss();

Hope may be its helpful.

Happy Coding :)

Answer 3

If you are transferring big data in intent result then it may not finish activity. e.g when i am putting byte array on image of big size, finish is not working, when i change image size same code works.
