Change "Exif" Data Between OnPictureTaken And Write()?

Solution 1:

The standard way of writing exif data in Android is by using the ExifInterface which sadly only works on files that have already been written to disk.

If you wish to do the exif write without using a library, then you would have to do it after your FileOutputStream is finished writing the file.

If you don't mind using a library, Sanselan (http://commons.apache.org/proper/commons-imaging/) might have the ability to do it to a byte[] array, but the documentation is pretty limited.
