CTD Upon Launch

[cosmobooker]

AudioAnchor insta-crashes upon launch after 2.4.0 upgrade via F-Droid. Restarting the phone and clearing the cache don't seem to help. I don't want to do a fresh install at the risk of losing all of the progress I have as my last backup is a few weeks old.

Android 16 on a Galaxy S25 Ultra

Clearing the app data "fixed" the crashing, but now it won't show album art on the home page. I downgraded to 2.3.3 for the meantime to restore that functionality.

I also hit this.

After clearing data, the new version can't see my SD card, only the internal storage. Neither can the 2.3.3 or 2.3.2. 😬 I think I must've installed and configured AudioAnchor one or more major Android version updates ago, and Google's war on user access to the filesystem has developed not necessarily in our favor. My old configuration was probably grandfathered in.

Welp.

Clearing the app data "fixed" the crashing, but now it won't show album art on the home page.

Did you perhaps have the "Display cover image from metadata" setting enabled?

[cosmobooker]

Did you perhaps have the "Display cover image from metadata" setting enabled?

I did check that setting, but toggling didn't seem to change anything.

[flackbash]

Thanks for reporting this. Can you please check which permissions AudioAnchor was granted, and particularly whether it was granted full access to images or restricted access only? If the latter is the case, please enable full access and see if that changes anything.

1. Exported database from 2.3.3.
2. Updated to 2.4.0 again.
3. Immedate CTD on launch, as described by issue title.
4. Clear cache -- does not resolve CTD.
5. Clear data -- now launches without crashing.
6. Add /storage/emulated/0/Podcasts, "directories containing audio files".
7. Pull to refresh and relaunch several times as AA has trouble scanning entire library without crashing (also present in 2.3.3).
8. Most subdir's album art is not getting picked up, but some is. Pattern:

• folder.jpg: not shown
• folder.png: shown
• NA - $channel_name - Videos.jpg: shown

9. Rename one of the folder.jpg to xfolder.jpg. It is now shown. (This seems highly suggestive of the culprit.)

My device is Android 12. According to Google, READ_MEDIA_IMAGES and _AUDIO were introduced in 13, and that is why they appear in the Requested permission list but not the Runtime list.

Furthermore,

~$ adb shell cmd appops get --uid com.prangesoftwaresolutions.audioanchor                                                                                                              0.114s 10:44

Finally,

10. import database saved in step 1.
11. AA crashes on launch again.

So the cause of the CTD seems to be something contained within the database created by 2.3.3.

Logs from the crash:

I have again uninstalled, reinstalled version 2.3.3, disable auto-update, and imported the database backup. Rolling back is kind of a hassle, so hopefully I have collected enough information to identify the bug.

I also experience a similar issue on Android 13. Although, I have not yet tried to downgrade.
For debugging purposes, I also attach the crash log and application information (as yump did in #216 (comment)):

Also I cannot grant more permissions in Android itself:

Hopefully this helps during debugging.

I experienced CTDs, too.

In my case it was caused by AudioAnchor not having the privilege to access the folders. The exception thrown is literally an invalid argument "file does not exist" error. I should still have a few crashes logged, in case anyone wants to look at them.

Previously, you could add folders outside the obvious trees (e.g. not under Music, Audiobooks, etc) and now this has become functionally impossible.

I did something (don't remember what because I had little time to figure out the issue) and the CTDs at launch went away, now those folders can still be added to the library, but they should show up empty, same as the ones that are still in the library.

I imagine this is a deliberate change, however it does create a problematic situation on the user's end not just for the CTDs but because progress will be lost unless the user can fix the database manually.

There is a fix for the crash in 031a980 but not for the missing image.

The source of the issue: AlbumCursorAdapter.bindView() decodes each album's cover with BitmapFactory, then unconditionally caches the result:

Bitmap image = BitmapUtils.decodeSampledBitmap(path, reqSize, reqSize);
addBitmapToMemoryCache(path, image);

BitmapFactory returns null instead of throwing when it can't decode a file, and addBitmapToMemoryCache() passes that straight into LruCache.put(), which throws exactly NullPointerException: key == null || value == null when the value is null (as seen in the logs above). This should be fixed with 031a980. This fix stops the crash. However, if something really is blocking a specific cover file from being read, that album will just show no cover. No crash, but no image either.

Still open: why the decode returns null for folder.jpg specifically. My first guess was that Android's media stack treats that filename specially and silently blocks reads to it under the storage permission changes in 2.4.0. I tested that directly — a folder.jpg cover file, a fresh install, deliberately without granting "All files access" — and it decoded and displayed with no problem. So that mechanism doesn't hold up, at least not on stock Android. It's possible this is specific to your device's manufacturer (some Android skins add storage restrictions on top of stock Android) rather than a general platform behavior, or something else about that particular file that I don't know about. Samsung's One UI is known to layer extra storage restrictions on top of stock Android in places, which would fit a manufacturer-specific explanation better than a general platform one.

Confirmed that this is not a Samsung issue as I have a Google Pixel now and was able to recreate the issue. If the new commits fix the crashing, I don't mind album art missing. Here's my steps to recreate:

2.3.3 working fine > Backup > Update to 2.5.0 via Fdroid > launch and CTS with below log file.

cleared app cache and data > launched and accepted full file access prompts > restored backup > CTS with no logs

Error in AudioAnchor bc1e53ba4dd0.txt

Thanks for the update!

It would be interesting to know whether setting the all-files-access permission fixes this to rule out that it is an permission issue. In case you have time to test that :)

Otherwise I'll just leave it at the crash-fix for now and try to get back to it later.
