I've moved from CalDAV/CardDAV to latest DAVdroid on my Android Samsung Ggalaxy S4. Open Tasks was already installed. But when opening the DAVdroid app, a warning appears saying OpenTasks is not installed. Options OK, Ignore and Install. When I choose "Install", Google Play Store will be opened with OpenTasks and options "Uninstall" and "open". Seems to be DAVdroid does not recognize OpenTasks on my phone.
Sharing debug info doesn't even work ("file not supported" or empty clipboard). I discoverd two warnings: "org.dmfs.permission.READ_TASKS permission denied" and "org.dmfs.permission.WRITE_TASKS permission denied". Does anybody have an idea, whats going wrong here?
Thanks in advance.
