title: Android AsyncTask example and explanation
body: <p>I want to use an <code>AsyncTask</code> in my app, but I am having trouble finding a code snippet with a simple explanation of how things work. I just want something to help me get back up to speed quickly without having to wade through <a href="http://developer.android.com/reference/android/os/AsyncTask.html" rel="noreferrer">the documentation</a> or lots of Q&amp;As again.</p>
