Write custom data as a Exif data in a JPEG image file
using ExifInterface
in Android
Would like to write/add
custom tags/exif
data in JPEG file
like name, age, etc... Right now i am able to write default values like Geo location data, attributes etc...
but can i write custom data in JPEG image using ExifInterface (Android)
Is this possible or any other alternative to maintain these short of information with image
Android's ExifInterface only lets you write exif tags that are "recognized." You can find SOME of the recognized exif tags in the link: http://developer.android.com/reference/android/media/ExifInterface.html
But the good news is, there's more exif tags that's not mentioned in the Android API. Bad news is, I still haven't found a library that lists all usable exif tags
After researching and experimenting for hours, I found that the following tag works:
"UserComment"
So the following code snippet will work:
String mString = "Your message here";
ExifInterface exif = new ExifInterface(path_of_your_jpeg_file);
exif.setAttribute("UserComment", mString);
exif.saveAttributes();
I'm still trying to find out which other exif tags are allowed, but for now, this should do the trick.
