title: Android: Save image to gallery from web screen
body: <p>I have a simple Android app which is just a collection of webviews. Normally in the default Android browser or Chrome, the user can long press on an image and save it to their phone.</p>
  
  <p>In the webview, the user doesnt have an option for long-pressing, but I'd like to be able to offer the same functionality for saving images to their phone.</p>
  
  <p>Is this possible through javascript or jquery, or any other method?</p>
  
  <p>Thanks.</p>
