Anything else?

I can not reproduce this on a Pixel 6 and Pixel 4 using GrapheneOS too.

According to https://developer.android.com/training/data-storage/shared/media when accessing the MediaStore and with Scoped storage enabled,

• we need granted the READ_EXTERNAL_STORAGE permission
• the files reside in one of the MediaStore.Images and MediaStore.Video collections

See

android/presentation/src/main/AndroidManifest.xml

Line 9 in 55d7f68

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

and

android/presentation/src/main/java/org/cryptomator/presentation/service/PhotoContentJob.kt

Lines 149 to 153 in 55d7f68

	builder.addTriggerContentUri(JobInfo.TriggerContentUri(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, FLAG_NOTIFY_FOR_DESCENDANTS))
	builder.addTriggerContentUri(JobInfo.TriggerContentUri(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, FLAG_NOTIFY_FOR_DESCENDANTS))
	builder.addTriggerContentUri(JobInfo.TriggerContentUri(MediaStore.Images.Media.INTERNAL_CONTENT_URI, FLAG_NOTIFY_FOR_DESCENDANTS))
	builder.addTriggerContentUri(JobInfo.TriggerContentUri(MediaStore.Video.Media.INTERNAL_CONTENT_URI, FLAG_NOTIFY_FOR_DESCENDANTS))
	builder.addTriggerContentUri(JobInfo.TriggerContentUri(MEDIA_URI, FLAG_NOTIFY_FOR_DESCENDANTS))

So I have currently no idea what the problem is here 🤔

[kokolem]

I can not reproduce on Pixel 4a with CalyxOS (Android 12). Perhaps this is a Graphene specific issue?

[NeverUsedID]

I can reproduce it on a pixel 7a with the Whatsapp Media folder. Deleting the folder does not help, as whatsapp recreates it after restart. Fast workaround would be to respect .nomedia file.
