• I have used the search function for open and closed issues to see if someone else has already submitted the same bug report.
• I will describe the problem with as much detail as possible.
• If the bug only to occurs with a certain podcast, I will include the URL of that podcast.

App version

2.7.1 (d5f0ef2)

Where did you get the app from

F-Droid

Android version

11 (really SailfishOS 4.5.0.18)

Device model

Sony Xperia X II

First occurred

After updating Android app supprt to Android 11 as part of the SailfishOS 4.5 update

Steps to reproduce

1. Use Android 11 or later (there were no issues on Android 10)
2. In Settings → Storage → Choose Data Folder make sure an external SD Card is selected (internal storage folder works fine) – in this case the setting was unchanged from before the system update
3. Any kind of feed or media download reports IO Error with detailed message No such file or directory

Expected behaviour

Update the feed obviously, took a really long time to figure out it wasn’t a network issue actually and where it tried to download these files to.

Current behaviour

For some reason it does detect if I manually create a directory where the feed file is supposed to be downloaded and reports this as the feed being of the wrong type as well as deleting the directory (so it obviously has write permissions to the place).

I’m starting to think it might simply not like the java.io.File.createNewFile call for some reason. It might be firmware bug, not really sure.

I’m starting to think it might simply not like the java.io.File.createNewFile call for some reason. It might be firmware bug, not really sure.

Made a test build from develop that skips that call and it still insists that it cannot open it…

And I also realized that even with a root shell I cannot run:

touch "/storage/d5c3ef56-eac1-4bd7-85cc-4c25e8ee0bd5/Android/data/de.danoeh.antennapod.debug/files/cache/feed-O1 Journale1"

… and it gives the same error code (No such file or directory) as is encountered by AntennaPod, while the same command with mkdir works fine. Guess it really is a firmware bug then. 🙁
