There's code on all platforms to force user to have dict prior to
opening a game or responding to an invitation. "Empty" dict play hasn't
made sense in a long time.
We've decided that on upgrade users shouldn't be surprised by a busy
board and unaware of how to fix it. So keep it the way it's been and let
the curious discover the new ability. Also, simplify code.
Create new class that owns the alert. Let it decide whether to post,
remove, etc. Seems to work, but I've removed some of the "reinvite"
options I'm not sure were helpful anyway. To be considered...
It's simpler this way, and I'm tired of stuff not happening because the
OS chooses not to schedule e.g. an invitation send for minutes. Goal's
to be running BluetoothServerSocket.accept() as much as possible when
there are active BT games in play OR when the game's in the foreground.
If that's happening, sent invitations and moves will be received when
users expect. When there's no traffic and app isn't being brought to
foreground, backoff will ensure I don't try to run accept() too often.
FWIW, BTLE seems to offer a better way to do this (to have an app be
responsive to incoming invitations when it hasn't run in the foreground
in a while), but it requires users to accept FINE_LOCATION
permission. I'm hoping I can make this work to avoid asking for that
permission.
The last change meant the test whether to show the words under the
pen-down cell would pass when it shouldn't because a drag to an occupied
location didn't register as movement. Change so movement counts to stop
the timer even if it wouldn't change the drag-target's location.
Rather than have a tile revert to its original location if it's dropped
where it can't be (on an occupied tile or outside the board), put it in
the last place it could have been. Do that by only updating cur when
it's to a legal location, and then relocating to cur when drag ends.
Not at all tested, but now the game's timestamp is kept and passed in to
where it can be used to determine, e.g., which of two Bluetooth device
names to keep for a given opponent.
Got as far as having gtk client display list of previously harvested
known players to be invited. Their addresses, or at least mqtt ids are
saved. Next is to actually invite one.
