I just upgraded Visual Studio for mac to support Android 8 / api 26. I updated the AppCompat library to 26.1 to use the new font folder in the Resources directory of my Android project. Now when I try to compile I get "Invalid resource directory name" for path "obj/Debug/res/font" APT0000.
First always check out the latest xamarin documentation about new features. https://developer.xamarin.com/guides/android/platform_features/introduction-to-oreo/
I quickly created a new xamarin android project and added two textviews with diffrent fonts:
My solution looks as the following:
I usually try to avoid capital letters in resource names as the android studio complains about it.
Main Layout:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" > <TextView android:text="Pacifico example text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:fontFamily="@font/pacifico" /> <TextView android:text="Roboto light example text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:fontFamily="@font/roboto_light" /> </LinearLayout> I think that you do not use the latest platform to build. Check that you use the latest platform (Oreo) to build the application.
For me the solution was to remove all the old Android SDK Build Tools from the SDK Manager. Now I only have for api level 26 and 27 installed and it works.
My resolution for this problem was to add the following line in the root of the project file
<PropertyGroup><AndroidSdkBuildToolsVersion>27.0.3</AndroidSdkBuildToolsVersion></PropertyGroup>
