Answer 1

To remove specific values: SharedPreferences.Editor.remove() followed by a commit()

To remove them all SharedPreferences.Editor.clear() followed by a commit()

If you don't care about the return value and you're using this from your application's main thread, consider using apply() instead.

Answer 2

Removing all preferences:

SharedPreferences settings = context.getSharedPreferences("PreferencesName", Context.MODE_PRIVATE);
settings.edit().clear().commit();

Removing single preference:

settings.edit().remove("KeyName").commit();

Answer 4

Deleting Android Shared Preferences in one line :-)

context.getSharedPreferences("YOUR_PREFS", 0).edit().clear().commit();

Or apply for non-blocking asynchronous operation:

this.getSharedPreferences("YOUR_PREFS", 0).edit().clear().apply();

Answer 5

If it is for your testing. You can use adb commands.

adb shell pm clear <package name>

Answer 6

You can use the adb shell to do this even without a rooted phone. The only catch is that the app must be debuggable.

run-as <your package name> <command>

For example:

run-as com.asdf.blah rm /data/data/com.asdf.blah/databases/myDB.db

Alternatively, you can just do the above but without the command which will direct you to the app package root and allow you to execute more commands in the app's context.
