.NET for Android(旧:Xamarin.Android)でVulkanを動かすのにSurfaceViewのANativeWindowを取得する必要がある。.NETだとANativeWindow_fromSurfaceをP/Invokeで簡単に呼び出せるのが便利。
[DllImport("android", CallingConvention = CallingConvention.Cdecl)]
public static extern IntPtr ANativeWindow_fromSurface(IntPtr env, IntPtr surface);
public static IntPtr GetANativeWindowFromSurfaceView(SurfaceView surfaceView) {
Surface surface = surfaceView.Holder.Surface;
IntPtr surfacePtr = JNIEnv.ToLocalJniHandle(surface);
IntPtr aNativeWindow = ANativeWindow_fromSurface(JNIEnv.Handle, surfacePtr);
return aNativeWindow;
}
