Delete shared preferences using an adb command

Question

I need to delete a shared preferences file using an adb command. Is there a way to do that without uninstalling the app?

I could not find anything that did it?

Answer 1

If you want to clear all the preferences, a single command will do it:

adb shell pm clear <package name>

Answer 2

Definitely not on an unrooted phone. On normal consumer builds (user builds), only the application itself can access the app's data.

If you have root, you can access the shell via

adb shell

Then navigate to the app's data directory (/data/data/<package name>), find the file and rm it.

Alternatively, you can do it all at once with

adb shell rm /data/data/<package name>/<file name>
