we’ve made good progress with our new lib ical4android and are proud to announce that ICSdroid is using the latest version of it now!
New in version 0.9.9:
allow to subscribe local files via file:/// URLs (use a file manager to open .ics files with “subscribe calendar (ICSdroid)” or enter the file URL manually)
don’t allow installation on SD card (causes removal of calendars sometimes)
update libical4android (better handling of VEVENTs without UID and recurring event exceptions)
small related UI changes and bug fixes
Version 0.9.9 has already been uploaded to Play Store. The source code is available on Gitlab. Binaries should be available in F-Droid soon, too.
If you have feedback, please do not hesitate to write us :-)!
