I want to lock files that is on the sdcard of android. I need to lock them so no one except my software can delete copy move or send them over bluetooth or any other way. How can I do it?

推荐答案

我想你想对文件进行加密。虽然该文件仍然可以到处移动，这将是无用的东西，但你的应用程序。人们将能够复制，移动，删除，但内容不会受到影响。

I think you want to encrypt the file. While the file can still be moved around, it will be useless to anything but your application. People will be able to copy, move, delete but the contents won't be compromised.
