Hi, i’ve just managed to succesfully build and run AugmentedImages project on android using custom images for tracking. I’ve used bone-stock-straight-out-of-the launcher 4.20.3 WITHOUT the arcoreimg.exe. The trick for me was to use sample images that had the same parameters as those in example, so i’ve used 4728x3264 8bit RGB jpg on compression level 9, and it worked like a charm on SGS7. When i’ve used 2k res png it failed to build, so maybe the file format is the problem in this case. Hope this helps anybody.
