Delete SharedPreferences File

Question

I am allowing the user to create multiple SharedPreferences files, but I also would like the option for them to delete these files. I know I could use internal

Answer 1

If you get SharedPreferences instance via Context.getSharedPreferences("X"), then your file will be named X.xml.

It will be located at /data/data/com.your.package.name/shared_prefs/X.xml. You can just delete that file from the location. Also check /data/data/com.your.package.name/shared_prefs/X.bak file, and if it exists, delete it too.

But be aware, that SharedPreferences instance saves all data in memory. So you'll need to clear preferences first, commit changes and only then delete preferences backing file.

This should be enough to implement your design decision.
