One thing that is important to understand with Exif data is that there are no required tags; each and every tag is optional — some services even specifically strip Exif data. Therefore throughout your code, you should always handle cases where there is no Exif data, either due to no data for a specific attribute or an image format that doesn't support Exif data at all (say, the ubiquitous PNGs or WebP images).

Some Notes

This is a class for reading and writing Exif tags in a JPEG file or a RAW image file. Supported formats include: JPEG, DNG, CR2, NEF, NRW, ARW, RW2, ORF and RAF.

Also, attribute mutation is supported for JPEG image files.

Adding the Library

Add the ExifInterface Support Library to your project with the following dependency:

compile "com.android.support:exifinterface:25.1.0"

But when an Exif attribute is exactly what you need to prevent a misrotated image in your app, the ExifInterface Support Library is just what you need to #BuildBetterApps

The basics are still the same: the ability to read and write Exif tags embedded within image files: now with 140 different attributes (almost 100 of them new to Android 7.1/this Support Library!) including information about the camera itself, the camera settings, orientation, and GPS coordinates.
