title: Unity requires Android SDK to be minimum API level 21
body: <p>So I've been trying to build a Unity 4.6.1 project in Android, but the problem is that my Android SDK is outdated. However, I believe Google discontinued support of the traditional ADT to switch to Android Studio. Android Studio doesn't have an easy to find SDK folder in version 1.0.1.  This is the error I get: "Error building Player: UnityException: Minimum platform required is Android 5.0 (API level 21)" How do I build my Unity project for Android, if the ADT doesn't have support for API level 21?</p>
