Is it possible to programmatically delete all sharedPreferences of an Android application, without knowing the file names? I mean all files, not all keys of a given file.
I'm running unit tests with instrumentation for several applications, and i need to clear every file the an app may create under /data/data/app.package.name/shared_prefs
folder.
For example an app may create these files under shared_prefs:
appname.xml
app.package.name_preferences.xml
app.package.name_tips.xml
while for another app i could have:
app.package.name_prefs.xml
app.package.name_foo.xml
Note: Using pm clear YOUR_APP_PACKAGE
the app crashes.
Thanks
To remove all prefs of the application you can use:
After that you have to
commit()
the removal.So it would look like that in full code:
