Question

How can I make a true splash screen in Android? I don’t want timers or delays. Just a splash screen that is shown until your application has loaded.

Answer 1

Something like

public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);

    handler = new Handler();

    new AsyncTask<Void, Void, Void>() {

    @Override
    protected Void doInBackground(Void... params) {
            //Do some heavy stuff
            return null;
        } 

        @Override
        public void onPostExecute(Void result){
            handler.post(new Runnable(){
                 @Override
                 public void run(){
                     setContentView(R.layout.main);
                 }
            });
        }
   }.execute();
}
