Thanks for your report.
This has been fixed with version 1.0.1.
Please, allow sharing of added calendars. This can de offered with a share icon of three nodes connected with two vertices. At least sharing via copy paste buffer is important.
Benefit is that calendar urls which need to be reused for adding a variation of that url makes it the user easier. Calendar urls are usually not the most easiest to enter. Also sharing them with others via e-mail, Telegram, etc. would then be possible. Note that sharing with copy paste buffer only holds the url. Sharing via other ways may also hold the title of the calendar.
Thank you for the nice suggestion. We will consider adding this feature in future version!
Thanks. Sending subscription URLs has been implemented in ICSdroid 1.3.
@rfc2822 Great to find this thread. I just want to suggest: Please also make the URL copyable, because this the more direct and accessible way to get in into the clipboard.
My point was that not everyone has installed this or thinks of installing it. For me, having the URL directly copyable would have saved me several times of re-typing lengthy strings of random characters
@jondo There is also https://play.google.com/store/apps/details?id=com.rejh.sharedr (will be FOSS and on F-Droid soon). But I prefer that one can share without having to install extra apps and the Android share facility is used, where possible.
