title: libgdx sendHttpRequest from android activity
body: <p>I created a simple game with the <em>libgdx</em> engine. I have a problem connecting to the server. If I make a request without the android part of my game, everything is all right. But when I try to connect from some activity, my request stops and does not enter to this method:</p>
  
  <pre><code>Gdx.net.sendHttpRequest(request, new Net.HttpResponseListener() {...}
  </code></pre>
  
  <p>If I try making a call in <code>MainActivity</code>, everything works fine. In other games with same code, everything works fine too. How can I properly connect?</p>
