On the Android device I would like to write a title and caption to a meta tag(s) structure within the header space of .jpg file. The Android library is already attaching helpful GPS data to the image. However, after taking a photo I want to write/attach/edit a title and photo caption into the meta tag space of the image file. How would I do that? I do not want to reinvent the wheel here. I prefer to use industry standard xml tag structure.

Then I send these photos to my ISP and there combined with some had coding on my part and for my proof-of-concept-to-self guided by this resource at http://www.php.net/manual/en/function.e ... d-data.php I write a nifty php script to extract/present a date, description....

$GPS = exif_read_data ('images/2010/IMG_0002.1.jpg','GPS' ,0 );
echo $DateTime = $GPS['DateTime'];
echo '


';
echo $ImageDescription = $GPS['ImageDescription'];
echo '


';
......

Your thoughts, guidance and/or links are gratefully appreciated.

Best,

Use the setAttribute() method of the ExifInterface constructor? Never tried it, but it looks like the best way.
