singleTop is necessary, as with singleTask we get the whole actvity
stack nuked on every launch. Open a game into BoardActivity then
background Crosswords; when you re-launch from the launcher or hold
the home key you're back to GamesList. But with singleTop incoming
invite schemes would launch a second instance because though there was
one running it wasn't in the same task as the browser firing the url
to redir.php. The solution there is to move the scheme intent from
GamesList to DispatchNotify, which is already handling notifications.
There the addition of a second launch flag means that an existing
instance will always see the launch through its onNewIntent -- under
tests I've come up with so far, anyway.
(eventually) explanatory text. Currently more-or-less works,
including sending an email with a link that when clicked launches
Crosswords. (Still need to respond to that link on receipt, but I'm
at least pulling out the necessary fields.)
Add an Application subclass that fetches the value from a preference,
a checkbox setting in advanced prefs, and modify the static when
that's changed at runtime.
work of pinging relay on timer. That work, which can cause receiver
to exceed its timeout if there are e.g. problems resolving hostnames,
must be done in a thread and Receivers aren't supposed to have
threads. Seems to work as well as it did before and also fixes
force-restart bugs when the network is slow/unavailable.
history, and store it in the game record in the DB (new column). This
will allow to not drop chat messages that arrive in the background,
though that's not implemented yet.
the only way to have it wind up on top *and without it being a second
instance of the activity* when relaunched in response to a move-made
notification. Even passing the SINGLE_TASK flag to the relaunching
Intent doesn't accomplish this.
that information to connect and not. There seems to be no way to get
notified when a socket's underlying transport goes down (might not
even want to) so this will be the best way to have the arrows go red
when the device goes into airplane mode.
