This class provides a low-level EXIF parsing API. Given a JPEG format InputStream, the caller can request which IFD's to read via parse with given options.

Below is an example of getting EXIF data from IFD 0 and EXIF IFD using the parser.

void parse() {
    ExifParser parser = ExifParser.parse(mImageInputStream,
            ExifParser.OPTION_IFD_0 | ExifParser.OPTIONS_IFD_EXIF);
    int event = parser.next();
    while (event != ExifParser.EVENT_END) {
        switch (event) {
            case ExifParser.EVENT_START_OF_IFD:
                break;
            case ExifParser.EVENT_NEW_TAG:
                ExifTag tag = parser.getTag();
                if (!tag.hasValue()) {
                    parser.registerForTagValue(tag);
                } else {
                    processTag(tag);
                }
                break;
            case ExifParser.EVENT_VALUE_OF_REGISTERED_TAG:
                tag = parser.getTag();
                if (tag.getDataType() != ExifTag.TYPE_UNDEFINED) {
                    processTag(tag);
                }
                break;
        }
        event = parser.next();
    }
}

void processTag(ExifTag tag) {
    // process the tag as you like.
}
