Any Android applications that target Android 6.0 (API level 23) or higher automatically participate in Auto Backup. This is because of the android:allowBackup attribute, which enables/disables backup. The property defaults to true in outystems-android projects as it is omitted from the AndroidManifest.xml file.

<application ...     android:allowBackup="true"> </app>

This may cause you an issues if you are trying to clear localStorage as it will automatically be restored when the app is re-installed.

If you don't want this default behavior on Android you can disable Auto Backup. Include allowBackup Android Plugin in your project.
