Android how to access the location data in a jpg

Question

I'm making an Android app that includes a feature to show images on a map.

How can I extract the location data from a .jpg file (if there is location data)?

Many thanks, Todd.

There is nice tutorial how to access exif data (that includes GPS info you need) from jpg that can help you:

The corresponding class is described in official docs:
