+### Android FileProvider Setup
+
+On Android, you must add a FileProvider definition and specify available files, which is documented [here](https://developer.android.com/reference/androidx/core/content/FileProvider#ProviderDefinition) or have a look at the demo app (AndroidManifest.xml and file_paths.xml).
