Android上的Worklight App Splash Screen

我正在将Worklight用于Android应用程序,

当我尝试添加启动画面时

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

我看到了启动画面,但是,我有一个黑屏,应用程序崩溃了
准确地说,它显示黑屏,当我点击选项按钮时,它会崩溃

当我删除“,2000”

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

我没有看到启动画面,应用程序正常工作.

我看到有人talked about that in IBM forums

有很多博客文章都在谈论Android的带有PhoneGap的splashsccreens
here和here,但我没有在这些帖子中看到我的问题的解决方案

以下是崩溃后的应用程序日志：

解决方法:

如果您使用的是Worklight 5.0.5.x,请尝试以下操作：

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);
}

如果您使用的是Worklight 5.0.6.x,请尝试以下操作：

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