title: Why do i keep getting "connection to the server was unsuccessful. (http://localhost:12896/)"?
body: <p>I'm using meteor 1.8.1 , when compile for android i use command "meteor run android --mobile-server=<a href="http://localhost:3000" rel="nofollow noreferrer">http://localhost:3000</a> --verbose" the app compiles fine but when it launches the app on emulator 
  a modal popup comes up and says "connection to the server was unsuccessful. (<a href="http://localhost:12896/" rel="nofollow noreferrer">http://localhost:12896/</a>)"
  could there be some config I'm missing?</p>
