Exif library for Android. It's based on the android [ExifInterface] 1 and on the [Jhead] 2 c library
Just add this line to your dependency group:
compile 'it.sephiroth.android.exif:library:+'
import it.sephiroth.android.library.exif2.ExifInterface;
import it.sephiroth.android.library.exif2.ExifTag;
ExifInterface exif = new ExifInterface();
exif.readExif( filename, ExifInterface.Options.OPTION_ALL );
// list of all tags found
List<ExifTag> all_tags = exif.getAllTags();
// jpeg quality
int jpeg_quality = exif.getQualityGuess()
// image size
int[] imagesize = exif.getImageSize();
// process used to create the jpeg file
short process = exif.getJpegProcess();
// gps lat-lon
double[] latlon = exif.getLatLongAsDoubles();
....
// save
exif.writeExif( src_file, dst_file );
