Install the components with the SDK Manager

Install the components with the SDK Manager

Although during the installation of Android Studio, basic SDK tools, you can install multiple components at any time, or check for updates later. To do this, click «Set«And then in»SDK Manager«With which you will enter the tool manager.

When you do this, a new window will open where it should select the programs you want to download or update. Some of the components that are recommended for updating are the following:

  • Tools for the Android SDK platform.
  • Android emulator.
  • Android SDK documentation.

In this section you can also select the APIs you want to use, which are used for users who use Android Studio to create applications. Once you’ve selected everything you need, you’ll only need to accept the licenses so that all the packages listed can be downloaded and installed.
