Just wanted to make sure that (1) your Android device can communicate roscore machines (eg. by ping, http etc)? (2) Is my_IP your roscore machine not your Android right? (3) No space b/w "http" and "//" ok?

Update) it's worthwhile to check NetworkSetup, although some of the checkups there might not work for Android.

Update) For (1), if 2 computers can communicate over IP, there's no way that a node on a computer connects to roscore that's running on another machine.
In general, it's worthwhile to check NetworkSetup, although some of the checkups there might not work for Android.
I'm not 100% sure if pinging in LAN succeeds in any situation, but at least http should go through. Easiest (not the most optimal though) way to check connection b/w 2 machines if roscore runs on Ubuntu might be running http server on it and access from Android. Can be done as:
On_Ubuntu$ sudo apt-get install apache2
Then on Android, open http://IP_Ubuntu.
