title: RxJava + RxAndroid WidgetObservable new API
body: <p>A few weeks ago this code worked fine with <code>RxAndroid v0.25.0</code></p>
  
  <pre><code>Observable&lt;OnTextChangeEvent&gt; usernameObservable = WidgetObservable.text(editText);
  
  usernameObservable
    .filter(e -&gt; e.text.length() &gt;= 3)
    .subscribe(e -&gt; log(e.text().toString()));
  </code></pre>
  
  <p>Since the <code>RxAndroid v1.0.0</code> release <a href="https://github.com/ReactiveX/RxAndroid/releases/tag/v1.0.0" rel="nofollow">https://github.com/ReactiveX/RxAndroid/releases/tag/v1.0.0</a></p>
  
  <p>Jake Wharton said that <strong>ViewObservable</strong> and <strong>WidgetObservable</strong>: are available here <a href="https://github.com/JakeWharton/RxBinding" rel="nofollow">https://github.com/JakeWharton/RxBinding</a> </p>
  
  <p>And although I have this imports:</p>
  
  <pre><code>compile 'io.reactivex:rxjava:1.0.14'
  compile 'io.reactivex:rxandroid:1.0.1'
  compile 'com.jakewharton.rxbinding:rxbinding:0.2.0'
  </code></pre>
  
  <p>That code doesn't work and I can't find any documentation.</p>
  
  <p>Do you have any code sample on how to do this simple thing?</p>
  
  <p>Am I missing something obvious?</p>
