[jquick-axway]

JIRA:

• https://jira.appcelerator.org/browse/TIMOB-28057
• https://jira.appcelerator.org/browse/TIMOB-25854
• https://jira.appcelerator.org/browse/TIMOB-28140
• https://jira.appcelerator.org/browse/TIMOB-27138

Summary:

• TIMOB-28057, TIMOB-27138 Modified WebView HTML <input/> handling:
  • Only supported on Android 5.0 and higher. (This is a limitation on Google's end. The old openFileChooser() method hack does not work on Android 4.4.)
  • Added "capture" attribute support to capture photos/videos via camera.
  • Honors Android 10 "scoped storage". (Replaced usage of getExternalStoragePublicDir() with MediaStore.)
  • No longer requires WRITE_EXTERNAL_STORAGE permission.
  • Now automatically prompts user for CAMERA permission if needed.
• TIMOB-25854 Added audio/video WebRTC support to WebView.
  • Will automatically prompt for CAMERA or RECORD_AUDIO permission if needed.
• TIMOB-28140 HTML Geolocation API now prompts for ACCESS_FINE_LOCATION permission if needed.
