We are developing a small game application using Xamarin forms in visual studio 2019. When I try to install the app in android tab 6.0 while I am getting an error "The installed package is incompatible. Please manually uninstall and try again.". Please give me a solution to resolve this issue

Note: Previously I unstalled app(Settings->Apps->myapp)

This is to inform you that I just factory reset my device after I can able to deploy. Anyway thanks for the reply-SomeStudent – P.Thiyagu

Couple of things to try:

  • See if updating Xamarin will help
  • rebuild/clean solution
  • close VS -> delete the bin and obj folders in your Xamarin Android project-> relaunch

The last step is usually what I have to do when Xamarin complains about having two versions of itself installed in one of my work projects since one of our branches has a brand new .csproj design so it is incompatible with the previous one
