Android SDK is a collection of tools and libraries that allow developers to create Android applications. To use the SDK, you must first agree to the license agreement. The license agreement is a set of terms and conditions that govern your use of the SDK. To accept the license agreement, open the Android SDK Manager on your computer. If you have not installed the Android SDK yet, you can download it from Google Play. In the left pane, click Installed Packages. In the right pane, under Android SDK Platform-tools, click Licenses. Click Agree and then click Install to install the license agreement. When you accept the license agreement, you are agreeing to follow all of its terms and conditions. The most important part of this agreement is that you must not distribute any applications that use the Android SDK without first obtaining a valid license from Google. You can find more information about licensing in Google’s Terms of Service for Developers website . ..
