change in logic to show login screen in app

I have attached [login to view URL] login screen come when user try click on button add to cart. But I want that login window to come immediately on opening the app after splash. I want whenever user open app he should be shown login screen of android app directly earlier I was showing login screen with below code import [login to view URL]; import [login to view URL]; import [login to view URL]; import [login to view URL]; import [login to view URL]; import [login to view URL]; /** */ public class Demo extends Activity { Button btn_done; @Override protected void onCreate(@Nullable Bundle savedInstanceState) { [login to view URL](savedInstanceState); setContentView([login to view URL]); btn_done = (Button) findViewById(R.id.btn_done); [login to view URL](new [login to view URL]() { @Override public void onClick(View v) { String urlis = " [login to view URL]"; [login to view URL](getApplicationContext(), "" + [login to view URL]("#login"), Toast.LENGTH_SHORT).show(); } }); } } As there is no event in future & I want to get login screen directly on execution of the url "[login to view URL]" code changes needed in above given code. Currently it check for the event of button click. Can you please help me on this.
