The Minecraft app, version 1.2.8 from Amazon Appstore,
crashed after starting up on my tablet device.

This problem could be something about connecting to servers
on the internet because when the app gets to the title screen,
it tries to sign in to my Xbox Live user account. Also, most of the
app crashes took place when the WiFi connection wasn't working.

After doing that, if the app is running, no similar
problems appear and the game can be played offline.

I have attached a screenshot image of some connections to
web services that Minecraft needed to make when starting up
- you can see that each URL there uses port 443 and
they are mostly from subdomains of xboxlive.com (15 items),
minecraft.net (3 items) or microsoft.com (3 items).

Please sort out this problem, thanks.
