Since you’ve refrained from giving us a stack trace, I’m giving this answer with a bit of guessing.

My guess is you’re getting a NetworkOnMainThreadException. This exception occurs on Android 3.0 and above, when you try to use the network on the main UI thread. This also explains why you don’t see the exception on Gingerbread.

To fix this, move all networking code into a Thread or an AsyncTask.
