Account migration works in most cases, though while testing I managed to
get it to fail in some rare occasions. This commit adds a check to
verify the number of contacts we thought we migrated is equal to the
number of contacts we have after migration.
If the check fails, it presents the user with a notification that opens
the relevant FAQ entry on the EteSync website.
Before this commit it was only used to override the api endpoint,
not it's also used to override the weburl. This is needed since we now
load the etesync website inside the app and not in an external web
browser.
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
