+ | ===== How to access data stored outside of the application folder in Android 11 and above? ===== | ||
+ | \\ | ||
+ | Starting with Android 11, drastic changes have been made by Google regarding how applications can access data stored outside of the application specific folders: except for file managers (and a few other specific cases), applications are only able to access media files from the shared storage spaces (internal device and removable SD card). It means that all your file-based maps and placemarks saved outside of the application specific folders are no more accessible. | ||
