如何在定製的Android主屏幕中添加默認的Widget？

我使用Launcher2 home screen作爲自定義主屏幕的基礎。我想用默認的Widget定製Android主屏幕。如何在定製的Android主屏幕中添加默認的Widget？

但是，當我用這個例子，我得到這個錯誤：

我已經在我的清單添加android.permission.BIND_APPWIDGET，但它仍然沒有工作，我的默認小部件仍下落不明。

有沒有人有任何想法可能是什麼問題？

android.permission.BIND_APPWIDGET不適用於系統存儲之外的應用程序。

沒有完整的堆棧跟蹤我無法確定錯誤的確切位置，但這是我所期望導致的問題。

void addAppWidget(Intent data) { 
     int appWidgetId = data.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, -1); 
     AppWidgetProviderInfo appWidget = mAppWidgetManager.getAppWidgetInfo(appWidgetId); 

     if (appWidget.configure != null) { 
      // Launch over to configure widget, if needed 
      Intent intent = new Intent(AppWidgetManager.ACTION_APPWIDGET_CONFIGURE); 
      intent.setComponent(appWidget.configure); 
      intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId); 

      startActivityForResultSafely(intent, REQUEST_CREATE_APPWIDGET); 
     } else { 
      // Otherwise just add it 
      onActivityResult(REQUEST_CREATE_APPWIDGET, Activity.RESULT_OK, data); 
     } 
}

所以我不能在我的HomeScreen應用程序中添加默認控件？ – user430926

是的你可以，你只需要在Launcher.java中修改上面的方法 – HandlerExploit

如何實現這個方法void addAppWidget（Intent data）。我在哪裏可以獲得意向數據，如果我想讓它顯示爲默認的部件，用戶不應選擇該部件。非常感謝。 – user430926
