DAVdroid > 126.96.36.199-ose compatibility issue
On Android 4.0.3, the last working version of DAVdroid is 188.8.131.52-ose. I’ve tried 1.6.2-ose and 1.6.3-ose and both make android freeze when trying to sync.
v184.108.40.206 is doing the job anyway, thanks for your work.
See DAVdroid 1.6.3 release notes: Android 4.1 is required now
