如何解决此java.lang.UnsupportedOperationException：这在Android L中不受支持？

我是尝试在多个项目点击使用MultiChoiceModeListener项目我我已经使用AppCompat v21.0.2得到了在onCreateActionMode方法 FATAL EXCEPTION分享，L更新之前，此代码的工作完全在AppCompat v19如何解决此java.lang.UnsupportedOperationException：这在Android L中不受支持？

@Override 
public boolean onCreateActionMode(ActionMode mode, Menu menu) { 
    // TODO Auto-generated method stub 
    mActionMode = mode; 
    nr = 0; 
    MenuInflater inflater = getActivity().getMenuInflater(); 
    inflater.inflate(R.menu.contextual_menu, menu); 

    MenuItem menuItem = menu.findItem(R.id.item_menu_share); 
    mShareActionProvider = (ShareActionProvider) menuItem 
     .getActionProvider(); 
    mShareActionProvider 
     .setOnShareTargetSelectedListener(PlanetFragment.this); 

    return true; 
}

例外：

更改：

mShareActionProvider = (ShareActionProvider) menuItem.getActionProvider();

到

mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(menuItem);

这是老问题，但我会后我的解决方案，也许有人会发现它有用。

@Override 
     public boolean onCreateActionMode(ActionMode mode, Menu menu) { 
      Log.d(TAG, "onCreateActionMode"); 

      mode.getMenuInflater().inflate(R.menu.list_select_menu, menu); 
      MenuItem item = menu.findItem(R.id.menu_item_share); 
      mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(item); 
      MenuItemCompat.setActionProvider(item, mShareActionProvider); 

      return true; 
     }
