无法在MvxFramentActivity中解析SupportFragmentManager

Question

Following along in the N=26 presentation for fragments, I am running into a problem where the SupportFragmentManager is not able to be resolved: I have MVVMCross and all dependencies (3.5.0), MVVMCross fragment support (3.5.0), and Xamarin Support Library v4 (21.0.3.0) added from NuGet with the references showing up properly in the project.

I also find the same issues with the project at https://github.com/MvvmCross/NPlus1DaysOfMvvmCross/tree/b405eef7dddf4d65b00116e142855653eae9f06b/N-26-Fraggle

Any ideas why this may be happening?

Answer 1

Check if your target API level and minimum API level are lower than 14. If yes, probably you will need to use Support V4:

using FragmentManager = Android.Support.V4.App.FragmentManager;

I hope you will solve.
