My bad, Jim is right, it’s finding the library. The linker is finding the library and the logs show no problem resolving the symbols needed (as far as the original logs show). The ‘unused DT entry’ part is discussed pretty well here: https://stackoverflow.com/questions/33206409/unused-dt-entry-type-0x1d-arg
All that looks benign. I found some writeups about Android getting more picky about DT entries and paths, but again, the logs don’t seem to show a problem. That should also be post 5.1.1, so even if it was a problem the Nexus shouldn’t show it.
Any other leads?
