Forget about my issue : I was tired last night 😮
I had imported the VCF first in thunderbird because I didn’t know yet I could do it in davdroid…
So it was the sogo connector that didn’t import correctly the VCF, not davdroid. I imported the VCF directly form davdroid and it’s OK. Great job and sorry for the noise 😉
Show open-source licenses correctly
The license texts, copyright notes etc. have to be available from within the app (and the source code, of course) without relying on external Web sites (i.e. offline within the app).
Add gradle / build tools?
Change Apache HttpClient to official version (Android port).
Robohydra should be mentioned, too (it’s used for the tests).
The source code needs to be available in the app? Really?
No, but it’s used for the build process, so it should be mentioned IMHO.
