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.
}

Reason: OP seems to call finish() of something else, but giving it a unique-name should ensure right thing's finish() is called.
