What is the SDK extension?

It stores an executable script, which includes a list of commands and functions written in ObjectScript. If you have ObjectDevel installed on your computer you can simply double-click the OS file to open it in ObjectDevel .

To open the SDK Manager from Android Studio, click Tools > SDK Manager or click SDK Manager in the toolbar .

A software development kit (SDK) is a collection of software development tools in one installable package . They facilitate the creation of applications by having a compiler, debugger and perhaps a software framework. They are normally specific to a hardware platform and operating system combination.

The SDK Extensions module decides the extension SDK level of the device and provides APIs for apps to query the extension SDK level . This module is updatable, meaning it can receive updates to functionality outside of the normal Android release cycle.
