Answer 1

You can't do Network operations on the main thread. Checkout : http://developer.android.com/reference/android/os/AsyncTask.html

for painless background threading :)

EDIT: Since I am still getting up-votes for this answer even though it's several years old I would no longer suggest using AsyncTask. It has many known problems which are described here (http://blog.danlew.net/2014/06/21/the-hidden-pitfalls-of-asynctask/). Instead I would urge you to use Retrofit or one of the other nice http clients which handles the threading for you.
