DAVdroid 1.9.1 update crashes and causes reboot loop
The DAVdroid update 1.9.1 causes an instant system crash on installation, and system crashes on boot which causes a reboot loop. The problem can be solved by removing the application (e.g. in recovery mode, rename /data/app/at.bitfire.davdroid-#; I have a number 1 and number 2, not sure which one is the actual one, seems like it's number 1). Reinstalling DAVdroid 1.9 afterwards gives a working application.
The issue has been reported on DAVdroid: https://forums.bitfire.at/topic/1603/replicant-lineage-1-9-1-causing-instant-crash-and-bootloops
Seeing that the developer seems doubtful that the problem is on his side, and that all the participants who reported the issue mention using F-Droid, I imagine the problem might be with the F-Droid build.
- CyanogenMod 12.1 (also reported on various CM, LineageOS and Replicant builds upstream)
- F-Droid 1.0.1
