推荐答案

没有亲爱的，你不能检查您的应用程序要卸载。

No dear you cant check that your application is going to uninstall.

当用户卸载应用程序，起初进程被终止，那么你的apk文件和数据目录被删除，在包管理器中的记录，告诉其意图过滤你已经注册以及其他应用。

When the user uninstalls the app, at first the process is killed, then your apk file and data directory are deleted, along with the records in Package Manager that tell other apps which intent filters you've registered for.

但你可以在你的缓存目录创建文件夹，这样，当你的应用程序将被删除所有文件夹和文件将自动被删除。

But you can create your folder in your cache dir so that when your application will be deleted all folders and files automatically will be deleted.

请检查一下。 http://developer.android.com/guide/topics/data/data -storage.html

因此​​，有没有办法让你的应用程序知道它正在卸载（不修改内核）。在数据/数据​​/ your.app.package创建的所有文件被卸载时自动删除。

So there's no way for your application to know that it is being uninstalled (without modifying the kernel). All files created in the data/data/your.app.package is deleted automatically upon uninstall.

另一种方法可能是有另一个应用程序，它会检查这个应用程序是否安装或没有。如果不是，它可以做清理工作。

Another approach could be to have another application that checks whether this application is installed or not. If not, it can do the clean-up work.
