  <p>Can we use EXIF to write arbitrary metadata, i.e. other than those specified in the <a href="http://developer.android.com/reference/android/media/ExifInterface.html" rel="nofollow noreferrer">ExifInterface documentation</a> (like latitude, longitude, flash etc). If not, what could be a preferred method of writing arbitrary metadata to image files?</p>
