cordova - Unable to load image when selected from the gallery on Android 4.4 (KitKat) using PhoneGap Camera Plugin

I'm trying to set the source of an img tag in my app based on the image chosen from the device image gallery using the PhoneGap/Cordova Camera Plugin.

It has worked previously as intended on older versions of Android (3.3) and works fine on iOS but now fails to resolve the image path on 4.4 (KitKat).

The returned path for the returned image url looks something like:

content://com.android.providers.media.documents/document/image%3A352

When I use this path to set as the image src via JavaScript, the URL cannot be resolved and therefore produces a load error. There is no issue when taking a picture with the camera, it only seems to occur when choosing an existing picture from the gallery.

I have tried encoding to base64 and also tried the method mentioned in the docs resolveLocalFileSystemURI(); but I have had no luck with these. I've also tried removing the camera plugin and rebuilding the app but no joy.

My guess is that something has changed with the way KitKat handles the gallery and PhoneGap/Camera plugin haven't been updated to accomodate for this yet.

A kind of really-very-dirty workaround works for me while this bug is fixed. Use in case of extreme necessity :)

if (imageURI.substring(0,21)=="content://com.android") {
  photo_split=imageURI.split("%3A");
  imageURI="content://media/external/images/media/"+photo_split[1];
}
