在这里，当我在屏幕上释放 longpress 时，我制作了我自己的主屏幕启动器，而不是我有一个选择选项的对话框，如小部件和快捷方式等。所以当我选择小部件时，我得到了另一个对话框，如内置应用程序小部件。当我选择任何小部件进行加载时，我遇到了问题
我引用 Android 2.3 源代码实现了整个代码。
在这段代码中，我有自己的内容提供者。当我使用 insert 对象从另一个类访问它的覆盖方法 ContentResolver 所以当我运行这个程序时，它给我错误就像下面提到的一样，我通过这个代码使用了这个
代码 :
这里的通知值是假的。
Uri result = cr.insert(notify ? LauncherSettings.Favorites.CONTENT_URI :
LauncherSettings.Favorites.CONTENT_URI_NO_NOTIFICATION, values);
