Where can AndroidObservable.fromBroadcast be found now?
<p>Before 1.0.0 there was <code>AndroidObservable</code> class with <code>fromBroadcast</code> method in  <a href="https://github.com/ReactiveX/RxAndroid/">RxAndroid</a> which would be used to subscribe for broadcast in reactive way. It was mentioned in <a href="http://blog.danlew.net/2014/10/08/grokking-rxjava-part-4/">Grokking RxJava</a>:</p>

<blockquote>
  <p>I also like <code>AndroidObservable.fromBroadcast()</code>, which allows you to create an <code>Observable</code> that works like a <code>BroadcastReceiver</code>. Here's a way to be notified whenever network connectivity changes:</p>

<pre><code>IntentFilter filter = new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION);
AndroidObservable.fromBroadcast(context, filter)
                 .subscribe(intent -&gt; handleConnectivityChange(intent));
</code></pre>

<p>After 1.0.0, RxAndroid dropped a lot of functionality and splitted into RxAndroid itself which now has only threading stuff, <a href="https://github.com/trello/RxLifecycle">RxLifecycle</a> and <a href="https://github.com/JakeWharton/RxBinding">RxBindings</a>.</p>

<p>None of them seem to contain <code>AndroidObservable</code> with <code>fromBroadcast</code> or <code>fromSharedPreferenceChange</code>.</p>

<p>Is it implemented in some actual and supported library?</p>
