title: How to debug Android's built-in browser for my website?
body: <p>My website works well on Google Chrome 42 and Mozilla Firefox 47 on Android, but doesn't work with Android's built-in browser (also with Opera Mini 17), how can I know which part of <code>javascript</code> that makes my site not running correctly?</p>
  
  <p><strong>Note</strong>: I didn't ask for debugging on Google Chrome or Mozilla Firefox mobile, but for Android's built-in browser or with Opera Mini</p>
