I have an After Effects animation, super simple, of a square moving around (AE shape). I export the animation as a .json using Bodymovin, and add the json file using Lottie in my project. So far, so good. 

The problem starts here --> during runtime, replace that "square" with an image I have in my project as well. Because this image may change, I can't add it statically to my AE animation, so need to dynamically add it during runtime. There's almost no information on how to do this in Android?
