ftc android studio install failed update incompatable

it seems really only adb removes the application completely.Ĭheck Xamarin.Froms release version before installing/reinstalling. NB: I also tried doing a factory reset, but did not remove the application/Allow the application to redeploy to the device. So somewhere in the device(I tested on both virtual and physical devices using kit kat, lollipop and marshmallow ) there was still a ghost copy of the application looming. Running it again actually then only gave the failure response I was hoping for, to know it was truly off the device. What worked for me was manually uninstalling the app in the applications (as all the helpful people pointed out), and then also firing up adb and then running uninstall returned a successful response. (I actually ended up doing reinstall of VS and then the SDK manager, which does not solve anything) However this in itself was a red herring. Then I started the SDK manager and noticed that I now have the latest SDK (25.1) which is fine but then this issue started popping up and my solution does not build. Unfortunately somewhere along the line I also undated my SDK( to 24 thinking it needed a later version to help) and when having VS and SDK manager doing updates (via nuget or other) the android sdk folder is cleared: this solution solves that problem. So it needs to have specifically version 23.3.0 and not the latest version 23.4.0, so uninstall each of these separate components manually and then only install Xamarin.Froms targeting release 23.3.0. Then when installing Xamarin.Froms there are lots of failures because again looking at the bottom of the page: However if you look closely at the release at the bottom of the page its latest release = 23.4.0 I initially installed one of these components to test/use in my solution via nuget:

First off I like to thank all for the hints and tips thus far, the issue has creeped in for me when on VS 2015 update 3 I it took me a couple of days to solve.
