Filter "no Tag" does not work

[StefanK21]

Describe the bug
When using the "no tags" filter all images are displayed and the filter is not checked.

To Reproduce

1. Go to the dialog filter
2. Select "no tags" (german: "Ohne Tags")
3. Activate the filter by clicking okay at the top.
4. All images are displayed including all tagged images.
5. reenter the filter dialog
6. the checkbox "no tags" is deselected.

Expected behavior
Display only images without tags (in the file or in the xmp). About a year ago it works.

Smartphone (please complete the following information):

• Android version : Android 9 on MI A1
• A Photo Manager Version (i.e. 0.4.6.160304) : 0.8.3.200315

Crash Report
If you report an app crash: Can you add the crash logfile to this ticket?

When APhotoManager crashes it tries to write a crash log file in the Error Log Folder.

• [ExternalStorageDirectory]/copy/log/androFotofinder.logcat-2017....txt
  • i.e. /storage/sdcard0/copy/log/androFotofinder.logcat-20170728-135704.txt
    • crash data from 2017-07-28 13:57

For more details on Error Loging see diagnostic settings.

Thanks for taking the time to write this "error"-report.

You must invoke apm-s "menu/more/Media scanner" before finding images by tags (or by having "no tags") work as expected.

Reason: Android's build in media scanner does not support "tags" so it does not add tag-infos into "android-s media database". apm-s "menu/more/Media scanner" adds additional infos to media database (tags, rating and non-exif-infos (iptc, xmp))

Find image by "no tags" means show all images that have no "tag" info in media database which is always true if you never run apm-s-media-scann (or if you copy/move a photo outside of apm)

Does my comment fix your problem?

I've scanned the DCIM folder severel times. But the problem is still there. :-(

[StefanK21]

I have reinstalled apm, startend the media scan. Still no success.
Then I wipe the media storage "index storage", rebooted the system, waited for the new system media scan, started the APM media scan. Still no success.

yesterday my lg-android-device got updated from android-9 to android-10 and it showed exact the same symptoms that you have:

Filtering for special fields tags, latitude and rating does not work any more under android because google has changed the media api.

my be your android-9 device got partial updates from android-10.

The app is not installable (or should not be installable) on android-10 devices but keeps on running if you update the android.

Sorry to say but we both have to wait until #169 and #155.
