推荐答案

如果您创建的任何文件夹上的设备的外部存储......有没有办法让你当用户卸载你的应用程序调用code。有些事情是自动删除（数据库，任何写入内部存储容量），而不是文件夹上的外部存储。

If you created any folders on a device's external storage... there is no way for you to call code when the user uninstalls your app. Certain things are removed automatically (databases, anything written to Internal Storage), but not folders on external storage.

编辑 - 正如史蒂芬，如果你的目标API级别8或更高版本，可以使用Context.getExternalFilesDir（）为您的外部文件，这些将在卸载删除

EDIT - As pointed out by Stephan, if you are targeting API Level 8 or higher, you can use Context.getExternalFilesDir() for your external files and those will be removed on uninstall.
