[OS X] Unable to select location of Android SDK in Unity browse dialog

I’m attempting to compile for Android but when I attempt to browse to the root folder of the Android SDK, it isn’t selectable because it has the .app extension and isn’t recognized as a folder. Someone else had the same problem (Android Studio on Mac OS - Accessing SDK through "Android Studio.app" - Unity Engine - Unity Discussions) but none of the answers worked.

People using OS X (Yosemite) and Android Studio: How do you set the location of the SDK in Unity?

Thank you!

Answer: [OS X] Remember to install the Android SDK via the SDK Manager, not Android Studio. - Web Resources - Unity Discussions
