title: Fatal Exception With APWidgets (Processing 3.0)
body: <p>I'm trying to use APWidgets for some basic Android buttons with Processing, but creating an APWidgetContainer throws the error:</p>
  
  <p>FATAL EXCEPTION: Animation Thread Process: processing.test.experiment, PID: 12094 java.lang.NoSuchMethodError: processing.core.PApplet.runOnUiThread</p>
  
  <p>My code is just:</p>
  
  <pre><code>import apwidgets.*;
  
  APWidgetContainer widgetContainer;
  
  void setup() {
  }
  
  void draw() { 
      widgetContainer = new APWidgetContainer(this);
  }
  </code></pre>
  
  <p>Does anyone have a solution, or know why this is happening?</p>
