With this change we no can launch external urls. For all I know this
doesn't work without this trick (an intent in the middle).
I also applied a transparent theme to the activity to avoid seeing the
launched activity briefly before opening external urls.
This is based on my experience working on "Share To Clipboard".
I was trying to avoid it, and keep it as davdroid both for attribution,
and making it easy to cherry-pick fixes from DAVdroid.
However, it seems to be causing clashes with the davdroid app, although
every piece of documentation claims otherwise.[1]
At least it seems like cherry-picks can still be achieved using:
git cherry-pick -s recursive -X find-renames=30 COMMIT
