title: blank screen comes before splash
body: <p>The main problem is the splash screen appears after 2-3 seconds. Before splash screen a blank layout appears which I don't want. Otherwise it runs fine. Just want to remove the blank layout which appears before the splash page. </p>
  
  <p>MainActivity:</p>
  
  <pre><code>public class MainActivity extends Activity {
  
      private static String TAG = MainActivity.class.getName();
      private static long SLEEP_TIME = 5; // Sleep for some time
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
  
          this.requestWindowFeature(Window.FEATURE_NO_TITLE); // Removes title bar
          this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);  // Removes notification bar
  
          setContentView(R.layout.activity_main);
  
          // Start timer and launch main activity
          IntentLauncher launcher = new IntentLauncher();
          launcher.start();
      }
  
      private class IntentLauncher extends Thread {
  
          @Override
          /**
           * Sleep for some time and than start new activity.
           */
          public void run() {
              try {
                  // Sleeping
                  Thread.sleep(SLEEP_TIME*1000);
              } catch (Exception e) {
                  Log.e(TAG, e.getMessage());
              }
  
              // Start main activity
              Intent intent = new Intent(MainActivity.this, Login.class);
              MainActivity.this.startActivity(intent);
              MainActivity.this.finish();
          }
