Add packages to your Android SDK. Before you can begin using the SDK for development, you will need to add the packages you want to use to your Android SDK. In the SDK Manager, you should see a list of all the available packages for download. For basic development, be sure to grab the following:
- The most recent Tools package in the Tools folder.
- The most recent version of Android (This is the first Android folder in the list).
- The Android Support Library, which can be found in the Extras Folder.
- Click Install when finished. The files will be downloaded and installed.
