How to get EXIF attributes that Android ExifInterface cannot find？

I am trying to read the EXIF information of images taken by a UAV (more specifically, DJI Mavic 2).

I have sucessfully get some attributes ( "GPS Altitude","GPS Longitude","GPS Latitude") by using ExifInterface.

However, I realize that ExifInterface is missing some attributes.

For example, I can't get "Relative Altitude", "Gimbal Roll Degree", "Gimbal Yaw Degree","Gimbal Pitch Degree", etc., although I can see these attributes on PC using some other software(exiftool for example).

How can I get these EXIF information?

Solution

  • I finally gave up ExifInterface and solved this by reading the raw bytes as HEX and parse the HEX into EXIF information.

    I also found a library here that should work, but didn't have a try as the issue was already solved.
