Answer 1

You can always do it programmatically as suggested by the other answers over here. But for development purpose, I find this Plugin very helpful as it speeds up my development significantly.

PLUGIN: ADB Idea

It provides you with features to Clear App Data and Revoke Permission from your Android Studio itself, just with click of a button.

Answer 2

To clear all SharedPreferences centrally from any class:

public static SharedPreferences.Editor getEditor(Context context) {
    return getPreferences(context).edit();
}

And then from any class: (commit returns a Boolean where you can check whether your Preferences cleared or not)

Navigation.getEditor(this).clear().commit();

Or you can use apply; it returns void

Navigation.getEditor(this).clear().apply();

Answer 3

You can use preferences.edit().remove("key").commit() to delete saved values from shared preferences.

Answer 4

In the class definitions:

private static final String PREFERENCES = "shared_prefs";

private static final SharedPreferences sharedPreferences  = getApplicationContext().getSharedPreferences(PREFERENCES, MODE_PRIVATE);

Inside the class:

public static void deleteAllSharedPrefs(){
    sharedPreferences.edit().clear().commit();
}

Answer 5

Just did this this morning. From a command prompt:

adb shell
cd /data/data/YOUR_PACKAGE_NAME/shared_prefs
rm * // to remove all shared preference files
rm YOUR_PREFS_NAME.xml // to remove a specific shared preference file

NOTE: This requires a rooted device such as the stock Android virtual devices, a Genymotion device, or an actual rooted handset/tablet, etc.

Answer 6

• To remove a particular value,

SharedPreferences.Editor remove(String key) followed by a commit() or a apply()

• To remove all the values,

  SharedPreferences.Editor clear() followed by a commit() or a apply()
