title: Disabling TalkBack usage hints ("Double tap to activate, double tap and hold for long press") after each sentence
body: <p>Im using Appcelerator for Android app, </p>
  
  <p>After I set the accessibilityHint property, the Talkback completes saying this string, pauses and always says "Double tap to activate, double tap and hold for long press". How do i disable this? Tried with accessibilityLabel or accessibilityValue but no luck. </p>
  
  <p>In .xml file</p>
  
  <pre><code> &lt;Label id='lblAppName' /&gt;
  </code></pre>
  
  <p>In .tss file</p>
  
  <pre><code>"#lblAppName":{
    accessibilityHint: 'Double tap here to activate me',
    text: L('app_name'),
    top:Alloy.Globals.sizes10,        
    left:Alloy.Globals.sizes58,
    right:Alloy.Globals.sizes57   
  }
  </code></pre>
