Question

After logout the user is directed to login screen in android. Now, if user clicks on back button of phone it should stay on login screen itself.

I have used following code in my application but it will close my application. It should stay on the login screen only

Intent objsignOut = new Intent(getBaseContext(),Hello.class);
objsignOut.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(objsignOut);

The actual solution is

@Override
    public void onBackPressed() {
        super.onBackPressed();
        finishAffinity();
    }

add this code in Login Activity. App closes when back button clicked in login page.
