Worklight App Splash Screen on Android

Question

I am using Worklight for an Android application,

When I try to add a splash screen

public class MyApp extends WLDroidGap {
    @Override
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       super.setIntegerProperty("splashscreen", R.drawable.splash);
       super.loadUrl(getWebMainFilePath(),2000);
    }       
}

I see the splash screen, but then, I have a black screen and the app crashes to be accurate, it shows a black screen, and when I tap on options button, it crashes

When I remove the ",2000"

public class MyApp extends WLDroidGap {
    @Override
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       super.setIntegerProperty("splashscreen", R.drawable.splash);
       super.loadUrl(getWebMainFilePath());
    }       
}

I don't see the splash screen, and the app works.

I see that someone talked about that in IBM forums

And there are many blog posts talking about splashsccreens for Android with PhoneGap here and here, but I dont see a solution in these posts to my problem

Here are the app log after the crash:

If you are on Worklight 5.0.5.x try this:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    super.loadUrl(getWebMainFilePath());  // yes, this is an extra invocation
    super.setIntegerProperty("splashscreen", R.drawable.splash);
    super.loadUrl(getWebMainFilePath(), 5000);
}

If you are on Worklight 5.0.6.x try this:

public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    super.setIntegerProperty("splashscreen", R.drawable.splash);
    super.bindBrowser(appView);
    super.loadUrl(getWebMainFilePath(), 5000);
}
