Adding SDK Packages

By default, the Android SDK does not include everything you need to start developing. The SDK separates tools, platforms, and other components into packages you can download as needed using the Android SDK Manager. So before you can start, there are a few packages you should add to your Android SDK.

To start adding packages, launch the Android SDK Manager in one of the following ways:

• In Eclipse or Android Studio, click SDK Managerin the toolbar.
• If you’re not using Eclipse or Android Studio:
  • Windows: Double-click the SDK Manager.exe file at the root of the Android SDK directory.
  • Mac/Linux: Open a terminal and navigate to the tools/ directory in the location where the Android SDK was installed, then execute android sdk .

When you open the SDK Manager for the first time, several packages will be selected by default. Leave these selected, but be sure you have everything you need to get started by following these steps:

Get the latest SDK tools

As a minimum when setting up the Android SDK, you should download the latest tools and Android platform:

1. Open the Tools directory and select:
   • Android SDK Tools
   • Android SDK Platform-tools
   • Android SDK Build-tools (highest version)
2. Open the first Android X.X folder (the latest version) and select:
   • SDK Platform
   • A system image for the emulator, such as
     ARM EABI v7a System Image

Get the support library for additional APIs

The support library is required for:

It also provides these popular APIs:

The Android Support Library provides an extended set of APIs that are compatible with most versions of Android.

Open the Extras directory and select:

• Android Support Repository
• Android Support Library

Get Google Play services for even more APIs

The Google Play services APIs provide a variety of features and services for your Android apps, such as:

To develop with Google APIs, you need the Google Play services package:

Open the Extras directory and select:

• Google Repository
• Google Play services

Note: Google Play services APIs are not available on all Android-powered devices, but are available on all devices with Google Play Store. To use these APIs in the Android emulator, you must also install the the Google APIs system image from the latest Android X.X directory in the SDK Manager.

Install the packages

Once you’ve selected all the desired packages, continue to install:

1. Click Install X packages.
2. In the next window, double-click each package name on the left to accept the license agreement for each.
3. Click Install.

The download progress is shown at the bottom of the SDK Manager window. Do not exit the SDK Manager or it will cancel the download.

Build something!

With the above packages now in your Android SDK, you’re ready to build apps for Android. As new tools and other APIs become available, simply launch the SDK Manager to download the new packages for your SDK.

Here are a few options for how you should proceed:

Get started

If you’re new to Android development, learn the basics of Android apps by following the guide to Building Your First App.

Build for wearables

If you’re ready to start building apps for Android wearables, see the guide to Building Apps for Android Wear.

Use Google APIs

To start using Google APIs, such as Maps or Play Game services, see the guide to Setting Up Google Play Services.

Installing the Android SDK

Android Studio provides everything you need to start developing apps for Android, including the Android Studio IDE and the Android SDK tools.

If you didn’t download Android Studio, go download Android Studio now, or switch to the stand-alone SDK Tools install instructions.

Before you set up Android Studio, be sure you have installed JDK 6 or higher (the JRE alone is not sufficient)—JDK 7 is required when developing for Android 5.0 and higher. To check if you have JDK installed (and which version), open a terminal and type javac -version . If the JDK is not available or the version is lower than 6, go download JDK.

To set up Android Studio on Windows:

1. Launch the .exe file you just downloaded.
2. Follow the setup wizard to install Android Studio and any necessary SDK tools.

On some Windows systems, the launcher script does not find where Java is installed. If you encounter this problem, you need to set an environment variable indicating the correct location.

Select Start menu > Computer > System Properties > Advanced System Properties. Then open Advanced tab > Environment Variables and add a new system variable JAVA_HOME that points to your JDK folder, for example C:\Program Files\Java\jdk1.7.0_21 .

The individual tools and other SDK packages are saved outside the Android Studio application directory. If you need to access the tools directly, use a terminal to navigate to the location where they are installed. For example:

To set up Android Studio on Mac OSX:

1. Unzip the downloaded zip file, android-studio-ide- -mac.zip .
2. Drag and drop Android Studio into the Applications folder.
3. Open Android Studio and follow the setup wizard to install any necessary SDK tools.

Depending on your security settings, when you attempt to open Android Studio, you might see a warning that says the package is damaged and should be moved to the trash. If this happens, go to System Preferences > Security & Privacy and under Allow applications downloaded from, select Anywhere. Then open Android Studio again.

Follow the links to install the SDK outside of the Android Studio directories.

The individual tools and other SDK packages are saved outside the Android Studio application directory. If you need access the tools directly, use a terminal to navigate into the location where they are installed. For example:

To set up Android Studio on Linux:

1. Unpack the downloaded Tar file, android-studio-ide- -linux.zip , into an appropriate location for your applications.
2. To launch Android Studio, navigate to the android-studio/bin/ directory in a terminal and execute studio.sh .

You may want to add android-studio/bin/ to your PATH environmental variable so that you can start Android Studio from any directory.

If the SDK is not already installed, follow the setup wizard to install the SDK and any necessary SDK tools.

Note: You may also need to install the ia32-libs, lib32ncurses5-dev, and lib32stdc++6 packages. These packages are required to support 32-bit apps on a 64-bit machine.

Android Studio is now ready and loaded with the Android developer tools, but there are still a couple packages you should add to make your Android SDK complete.

The stand-alone SDK Tools package does not include a complete Android development environment. It includes only the core SDK tools, which you can access from a command line or with a plugin for your favorite IDE (if available).

If you didn’t download the SDK tools, go download the SDK now, or switch to the Android Studio install instructions.

To get started on Windows:

Your download package is an executable file that starts an installer. The installer checks your machine for required tools, such as the proper Java SE Development Kit (JDK) and installs it if necessary. The installer then saves the Android SDK Tools to a specified the location outside of the Android Studio directories.

1. Double-click the executable ( .exe file) to start the install.
2. Make a note of the name and location where you save the SDK on your system—you will need to refer to the SDK directory later when using the SDK tools from the command line.
3. Once the installation completes, the installer starts the Android SDK Manager.

To get started on Mac OSX:

Unpack the ZIP file you’ve downloaded. By default, it’s unpacked into a directory named android-sdk-mac_x86 . Move it to an appropriate location on your machine, such as a «Development» directory in your home directory.

Make a note of the name and location of the SDK directory on your system—you will need to refer to the SDK directory later when using the SDK tools from the command line.

To get started on Linux:

Unpack the .zip file you’ve downloaded. The SDK files are download separately to a user-specified directory.

Make a note of the name and location of the SDK directory on your system—you will need to refer to the SDK directory later when using the SDK tools from the command line.

Troubleshooting Ubuntu

• If you need help installing and configuring Java on your development machine, you might find these resources helpful:
  • https://help.ubuntu.com/community/Java
  • https://help.ubuntu.com/community/JavaInstallation
• Here are the steps to install Java:

  1. If you are running a 64-bit distribution on your development machine, you need to install additional packages first. For Ubuntu 13.10 (Saucy Salamander) and above, install the libncurses5:i386 , libstdc++6:i386 , and zlib1g:i386 packages using apt-get :

     For earlier versions of Ubuntu, install the ia32-libs package using apt-get :

     The Android SDK tools are now ready to begin developing apps, but there are still a couple packages you should add to make your Android SDK complete.

     Then, select which SDK bundle you want to install:

     SDK Build Tools Release Notes

     See Also

     Build Tools is a component of the Android SDK required for building Android application code. The latest version of these tools is included in the SDK starter package and installed in the /build-tools/ directory.

     You should always keep your Build Tools component updated by downloading the latest version using the Android SDK Manager. By default, the Android SDK uses the most recent downloaded version of the Build Tools. If your projects depend on older versions of the Build Tools, the SDK Manager allows you to download and maintain separate versions of the tools for use with those projects.

     To use a specific version of the Build Tools in your application project:

     1. In the root folder of your application project, find the project.properties file.
     2. Open the file and specify the Build Tools version by adding a buildtools property on a separate line:
     1. In the root folder of your application project, find the build.gradle file.
     2. Open the file and specify the Build Tools version by adding a buildToolsVersion property to the android section:
