SDK Manager
The Android SDK separates tools, platforms, and other components into packages you can download using the SDK Manager. For example, when the SDK Tools are updated or a new version of the Android platform is released, you can use the SDK Manager to quickly download them to your environment.
You can launch the SDK Manager in one of the following ways:
- From Eclipse (with ADT), select Window >Android SDK Manager.
- From Android Studio, select Tools >Android >SDK Manager.
- On Windows, double-click the SDK Manager.exe file at the root of the Android SDK directory.
- On Mac or Linux, open a terminal and navigate to the tools/ directory in the location where the Android SDK is installed, then execute android sdk .
You can select which packages you want to download by toggling the checkboxes on the left, then click Install to install the selected packages.
Figure 1. The Android SDK Manager shows the SDK packages that are available, already installed, or for which an update is available.
There are several different packages available for the Android SDK. The table below describes most of the available packages and where they’re located in your SDK directory once you download them.
Recommended Packages
Here’s an outline of the packages required and those we recommend you use:
SDK Tools Required. Your new SDK installation already has the latest version. Make sure you keep this up to date. SDK Platform-tools Required. You must install this package when you install the SDK for the first time. SDK Platform Required.You must download at least one platform into your environment so you’re able to compile your application. In order to provide the best user experience on the latest devices, we recommend that you use the latest platform version as your build target. You’ll still be able to run your app on older versions, but you must build against the latest version in order to use new features when running on devices with the latest version of Android.
To get started, download the latest Android version, plus the lowest version you plan to support (we recommend Android 2.2 for your lowest version).
System Image Recommended. Although you might have one or more Android-powered devices on which to test your app, it’s unlikely you have a device for every version of Android your app supports. It’s a good practice to download system images for all versions of Android your app supports and test your app running on them with the Android emulator. Android Support Recommended. Includes a static library that allows you to use some of the latest Android APIs (such as fragments, plus others not included in the framework at all) on devices running a platform version as old as Android 1.6. All of the activity templates available when creating a new project with the ADT Plugin require this. For more information, read Support Library. SDK Samples Recommended. The samples give you source code that you can use to learn about Android, load as a project and run, or reuse in your own app. Note that multiple samples packages are available — one for each Android platform version. When you are choosing a samples package to download, select the one whose API Level matches the API Level of the Android platform that you plan to use.
Tip: For easy access to the SDK tools from a command line, add the location of the SDK’s tools/ and platform-tools to your PATH environment variable.
The above list is not comprehensive and you can add new sites to download additional packages from third-parties.
In some cases, an SDK package may require a specific minimum revision of another package or SDK tool. The development tools will notify you with warnings if there is dependency that you need to address. The Android SDK Manager also enforces dependencies by requiring that you download any packages that are needed by those you have selected.
Adding New Sites
By default, Available Packages displays packages available from the Android Repository and Third party Add-ons. You can add other sites that host their own Android SDK add-ons, then download the SDK add-ons from those sites.
For example, a mobile carrier or device manufacturer might offer additional API libraries that are supported by their own Android-powered devices. In order to develop using their libraries, you must install their Android SDK add-on, if it’s not already available under Third party Add-ons.
If a carrier or device manufacturer has hosted an SDK add-on repository file on their web site, follow these steps to add their site to the Android SDK Manager:
- Select Available Packages in the left panel.
- Click Add Add-on Site and enter the URL of the repository.xml file. Click OK.
Any SDK packages available from the site will now be listed under a new item named User Add-ons.
Troubleshooting
Problems connecting to the SDK repository
If you are using the Android SDK Manager to download packages and are encountering connection problems, try connecting over http, rather than https. To switch the protocol used by the Android SDK Manager, follow these steps:

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:
- Launch the .exe file you just downloaded.
- 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:
- Unzip the downloaded zip file, android-studio-ide- -mac.zip .
- Drag and drop Android Studio into the Applications folder.
- 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.
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:
- Unpack the downloaded Tar file, android-studio-ide- -linux.zip , into an appropriate location for your applications.
- 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.
- Double-click the executable ( .exe file) to start the install.
- 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.
- 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.

Install Android Development Tools
Before You Begin
This 15-minute tutorial shows you how to install Android Studio, which includes the Android SDK, and create an Android Virtual Device (AVD) on which you install an Oracle JavaScript Extension Toolkit (Oracle JET) hybrid mobile application during a later tutorial. The time to complete doesn’t include processing time as a result of your activities.
Background
The Oracle JET command-line interface invokes the Android SDK that you install with Android Studio to build an Android application package (APK) file from the source files of your hybrid mobile application. This APK file is installed on an AVD to enable you to test the hybrid mobile application.
What Do You Need?
- A computer that meets the system requirements to install Android Studio. See System requirements at https://developer.android.com/studio/
Install and Set Up Android Studio
Depending on the operating system of your computer, the Android Studio installation wizard prompts you with dialogs where you choose between standard or custom install types. Choose the options recommended by the Android Studio installation wizard as these options include the components that you require to create and install a hybrid mobile application on an AVD. They also include an Android emulator and an emulator accelerator appropriate for your computer, be that Windows, Mac, or Linux.
- Go to the Download page for Android Studio on the Android Developer’s website at https://developer.android.com/studio/ and click DOWNLOAD ANDROID STUDIO.
- Review and accept the terms and conditions in the Download Android Studio dialog that appears and click DOWNLOAD ANDROID STUDIO FOR PLATFORM where PLATFORM refers to the operating system of your machine, such as Windows, Mac, or Linux.
- Go to the Install Android Studio guide at https://developer.android.com/studio/install and follow the instructions for your operating system to install and start Android Studio.
- If you run Android Studio behind a firewall or secure network, an Android Studio First Run dialog appears which displays a button (Setup Proxy) that you click to enter the proxy server settings for your environment. This allows Android Studio to complete the download of the components for a standard install.
- In the Welcome to Android Studio dialog, select Start a new Android Studio project, and then, in the Create New Project wizard, accept the default options to progress to the final screen in the wizard and click Finish.
This enables the Android Studio toolbar with the options that you need to create an AVD. It also downloads and configures the Gradle build tool that the Android SDK invokes to build the APK file when you complete the creation of your Oracle JET hybrid mobile application.
If you run Android Studio behind a firewall or secure network, a Proxy Settings dialog appears that enables you to configure proxy settings for the Gradle build tool that Android Studio downloads and configures. Provide the proxy settings for your environment to ensure that the Gradle build tool functions correctly.
