Android SDK

The Android Software Development Kit is the SDK for writing Android applications.

Android depends on the JDK to compile Android applications, but once the application gets installed on Android, the Android Runtime or Dalvik (depending on the Android version) runs the application.

Android's class library (both the core Java classes and Android-specific APIs) is contained in android.jar and has lots of types spread over several namespaces (or "packages", in Java lingo).
