Our usage

• We are using the work manager to schedule google backup for WhatsApp (only on android 12 and above).
• The worker is scheduled with WorkManager.beginUniqueWork(), policy is REPLACE.
• The OneTimeWorkRequest has the following constraints:
  • requiresBatterNotLow() set to true
  • Network is set to unmetered (for most users) and to not roaming of others
  • Backoff strategy is linear with 300 seconds initial delay
• Work Manager Lib version: 2.8.1

Signal is collected by counting WorkerFactory.createWorker, for the same workerClassName. And having logs in the worker itself.

Problem

We see situations when the work manager starts our worker and cancels it and restarts it again in a short period of time (anecdotal data show cases where the worker was started 1k (and more) times in an hour.

Devices/Android versions reproduced on:

mostly different Samsung devices (but this is #1 manufacturer and we see on other devices too so no reasons to believe it is manufacturer specific issue). Android versions: 12/13/14

Here is a small snippet of the logs we have for such problems (will be happy to provide more logs and add more details and collect new logs when it will be clear what else is important for debugging the problem)
