This just started happening today in our PCL on Android building from Visual Studio on a Mac with OS High Sierra. My co-worker building the same project on his Windows 10 machine has no problems at all. I just got a fresh pull from the repository too. No changes added.
This is the full error (I get it twice):
Error APT0000: 1: error: Error: No resource found that matches the given name: attr 'android:keyboardNavigationCluster'. (APT0000) (Project.Android)
Here is what I find of it online:
There is nothing on this. I don't know how to fix this. It prevents me from building for Android. Please help.
