App regularly stopped during Android backups

Question

App regularly stopped during Android backups

Opened this issue 3 months ago · 1 comments

Problem

One solution is to deactivate Android backups.

However, we wanted to provide you with the Android logs as you might be able to derive possible improvements for the app:

Interesting Log Lines

The key issue seems to be that the backup quota is exceeded:

10-05 14:21:20.491 13837 13850 I Backup  : [FullBackupSession] Package com.kelvin.sensorapp failed pre-flight size check at 8890231808 bytes

10-05 14:21:20.499  1730 16118 I PFTBT   : Transport suggested backoff=0
10-05 14:21:20.499  1730 16118 I PFTBT   : Transport quota exceeded for package: com.kelvin.sensorapp

In our use case, all data is transferred to a REST endpoint (so actually no backup needed) but obviously still kept on the device.

Shortly after, the app crashes:

10-05 14:21:20.582  1730  2681 I WindowManager: WIN DEATH: Window{cd82622 u0 com.kelvin.sensorapp/com.kelvin.sensorapp.MainActivity}

Hope that input helps you.

(As already mentioned, our current solution is to turn off Android backups completely.)

Thanks, it would seem like just turning off the backups completely is the most sensible thing to do for now. I will look into this further in due course.
