I know this was a problem from a while ago looking at all the posts on it, but was the problem with android devices being misidentified as incompatible with Collector ever fixed? I am emulating a device with Android Studio so that might be the problem, but the emulated device meets all the requirements I think; however, I still get the incompatible message. I'm pretty sure it meets all the requirements because I can download other ArcGIS apps like Workforce, Indoors, Navigator, etc. with no issue. I can't really install it separately on my machine and then deploy it because of the emulation factor.
