The Android Software Development Kit (SDK) is a crucial part of Android development for beginners to come to grips with.

Android development starts with the Android SDK - a collection of tools needed to build any kind of Android app. Discover what's included and how to use it.

Previously, you'd have to download Android Studio or the SDK to get these, which are a 400MB-1.6GB download. Even the smaller command line tools download is still 200-300MB.

By default, all of the SDK platforms, samples, and APIs will be selected for install. This can take quite a while to download, as several versions of Android are currently available.
