Android 11 - Scoped Storage

Overview:

Android 11 (API level 30) further enhances the platform, giving better protection to app and user data on external storage.

This release introduces several enhancements, such as raw file path access, batch edit operations for media, and an updated UI for the Storage Access Framework.

Changes:

On Android 11, apps with the read external storage permission are able to access files with file paths in the scoped storage environment. On Android 10 devices, this is not available to apps in the scoped storage environment unless they have opted out by setting the android:requestLegacyExternalStorage manifest attribute.

Android 11 allows you to use APIs other than the MediaStore API to access media files from shared storage using direct file paths. These APIs include the following:

• The File API.
• Native libraries, such as fopen().

Proposed Actions:

• Check if Qt Android accesses files with filepaths outside
• Check our usage of MediaStore API. Do we save or load resources using MediaStore? Should we?
• How we proccess file system URI´s (content uris, direct file, etc)
• Follow this: https://developer.android.com/training/data-storage/use-cases#access-file-paths
• Check android manifest flags and API target.
