Android: Save file permanently (even after clear data / uninstall)

Question

I would like to know if there is a way to store a small amount of data permanently.
By permanently I mean I want the data to persist even if user clears app data / unins

Answer 1

Environment.getDataDirectory() is at least one directory where you can save files. It's on the internal storage (/data).

One case I use it is to define whether a service is running; I create a .lock file in there and always check whether it exists or not.
