The SDK platform along with the platform and build utilities can be selected or deselected for installation from the Android SDK manager. Users can also take advantage of an emulator and all the libraries required for building tools optimized for Android. Samples projects complete with source code and tutorials can be used by first-time Android developers to get a better idea of how everything works. Build, compile, test and debug Android apps using this SDK It can also be used with the sdkmanager command-line utility as well as with the help of Eclipse and Java Development Kit (JDK).

The software development kit is part of Android Studio and the SDK tools package. Released by Google, Android SDK provides developers with all the necessary tools, components and libraries for creating, compiling, testing and debugging mobile applications compatible with the Android operating system.
