Thanks, TJ. I have a copy of Avare 11.0.5 as a backup. I mostly use X tho, and would only need to load a later version if it was broken (ie, a change in maps format, etc). As long as I have the basic functions as a backup, its all I need.
Its the updates to X that I need, but again, I just need the APK for my backup tablet, so as long as nothing gets screwed up, I can use my primary. I'll probably just see if I can build an APK from github/andriod studio.
Rather ironic, I have put up with the "buy new hardware" answer from Micro$oft since the 90s, and it was the same answer from Foreflight that made me reject them out of hand, and brought me here.
