Periodic Sync sometimes fails silently with DeadObjectException

[sunkup]

Android 15. Not reliably reproducible. Just set the interval to 15 min, close ICSx5 and wait.

Seems to only occur on enqueued periodic syncs until now. Not on manual syncs.

Work [ id=d4370a48-a6cf-4f68-90a8-c81d9e28e6a3, tags={ at.bitfire.icsdroid.PeriodicSyncWorker } ] failed because it threw an exception/error

I can confirm scheduled sync stopped working for me on Android 15 (Pixel 6a). My only external calendar is an Outlook one. Manual sync works without problem.

I don't see any logs or error messages (don't know how, but willing to test if deemed useful).

Same problem here on Android 15 (Pixel 8 pro).

[sunkup]

@zenlord @MadPierrot does this work for you?

[zenlord]

Looks like it worked. I had already tried setting a different sync interval, which did not work, but now I have set it back to the initial interval and it started syncing automatically again (for me at least).

Thx!

@sunkup , on my device it works for the next sync interval, then the software stops again.
