Android - Mime Type: null

[Ngorror]

MimeTypeMap.getFileExtensionFromUrl is case sensitive
It cannot process .JPG

suggested fix in Open.java:

  private static String getMimeType(String path) {

    String mimeType = null;
    String pathToLower = path == null ? null: path.toLowerCase();

    String extension = MimeTypeMap.getFileExtensionFromUrl(pathToLower);

P.S.
I'm building my cordova app on windows
