Android mobile to mobile communication offline mode
<p>General question.  Im looking at writing an Android app that communication wise is a lot like say a chess game.  Player one opens his chess app, sends his "move" to as second player.  Second player may be powered off or what ever (i.e. he's offline) so it's not a live exchange.  Player 2 eventually goes online and receives the player 1 "move".  Now without using GCM which requires a Third party server, is there a way of doing mobile to mobile communication exchanges.  I was thinking of using just emails with attachments.  But perhaps there is a better way.</p>
