我的一个 Android 应用程序的用户报告说，他的版本在更新后“消失了”。其他（数千名）用户都没有报告问题。
This morning I tried to open up the app but could not get anything.
I tried and tried and then physically turned my phone off and back on.
Now the icon has disappeared.
他在应用程序中存储了大量数据，因此无法删除并重新安装。
I think the problem has been caused by another apps update which happened yesterday.
I can see your icon in my apps list but it is the only one that is black and white, all the rest are in colour.
When I view the properties of your app it says:
Storage 20.00KB
Application 0.00KB
Data 20.00KB
It gives an option to clear data or uninstall.
My memory card, which I haven't removed, says I have 55mb of data left.
是什么导致了这种情况，我能做些什么来避免这种情况在未来发生在用户身上，我有什么建议可以解决他的问题吗？
