Answer 1

I was having the similar issue and I found out that in some versions of android (from honeycombs) it's not allowed by default to perform network operation from main thread. So you can resolve it in 2 ways. Perform operation in different thread or allow to make network operation in main thread. To do that use something like this:

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitNetwork().build();
StrictMode.setThreadPolicy(policy);
