Android: Delete app associated files from external storage on Uninstall?

Question

It\'d be convenient if an application I\'m writing stored some files to external storage permanently (so they persist after the application has been exited[destroyed]), but

Answer 1

Yes, this is possible. Simply write your files to the external files directory:

File dir = getExternalFilesDir(null);

This will create a folder at /Android/data/your.package/. Note that this is not External as in sdcard, but it is publicly accessible. If a user uninstalls your app, this directory will also be removed, along with all of its contents.
