title: "Share Image" button for Android App
body: <p>Lets say I have an Android html5 app with a picture generated with Javascript by passing a canvas to base64 and then appending it to DOM. I want to add some buttons to my app in order to share that image in, at least, Twitter and Facebook.</p>
  
  <p>I've already seen how to trigger the "Intent" dialog with Java too. Is there any way to do that with Javascript?</p>
  
  <p>Thanks.</p>
