Hi I'm developing a Titanium Android module for video casting on Chromecast. I am creating menu programmatically. I'm using below code for this:

Code for menu 

protected Menu newMenuInstance(Context context) {
    try 
    {
        Class<?> menuBuilderClass = Class.forName("com.android.internal.view.menu.MenuBuilder");
        Constructor<?> constructor = menuBuilderClass.getDeclaredConstructor(Context.class);

        return (Menu) constructor.newInstance(context);
    } catch (Exception e) {
        e.printStackTrace();
    }

    return null;
}

Code for cast button: 

@Kroll.method
public void castButtonLoader(){

    Menu menu= newMenuInstance(TiApplication.getInstance());

    int menuId= TiApplication.getAppRootOrCurrentActivity().getResources().getIdentifier("main", "menu",TiApplication.getInstance().getPackageName());
    new MenuInflater(getActivity().getApplicationContext()).inflate(menuId, menu);

    MenuItem mediaRouteMenuItem;    
    mediaRouteMenuItem = menu.findItem(menuId);

    MediaRouteActionProvider mediaRouteActionProvider = (MediaRouteActionProvider) MenuItemCompat.getActionProvider(mediaRouteMenuItem);
    // Set the MediaRouteActionProvider selector for device discovery.
    mediaRouteActionProvider.setRouteSelector(mMediaRouteSelector);
}

It is returning given error:

MenuItemCompat: getActionProvider: item does not implement SupportMenuItem; returning null

Can anyone please help why this error is raising?

We are using the AppCompat library so it looks like this errors is telling you this will only accept menu items that also come from AppCompat:

android.support.v7.internal.view.menu.MenuBuilder

  • Could you please suggest what are the changes required for creating menu items from AppCompat in the given scenario. Thanks – Chandan Wadhwa Dec 14 '15 at 14:27
  • Replace "com.android.internal.view.menu.MenuBuilder" with "android.support.v7.internal.view.menu.MenuBuilder" and might need to import that class as explained in http://stackoverflow.com/questions/24809580/noclassdeffounderror-android-support-v7-internal-view-menu-menubuilder – Fokke Zandbergen Dec 16 '15 at 18:14
