IL2CPP build (Unable to locate Android NDK).

Hello, guys, I’m having trouble building my game. I’m using Unity 2019.2.15f1

When I switch the Scripting Backend to MONO. The build will always be successful.
But when I switch to IL2CPP. The build will always show an error saying “Unable to locate Android NDK”.
