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 Platform Tools release notes

     Android SDK Platform-Tools is a component for the Android SDK. It includes tools that interface with the Android platform, such as adb , fastboot , and systrace . These tools are required for Android app development. They’re also needed if you want to unlock your device bootloader and flash it with a new system image.

     Although some new features in these tools are available only for recent versions of Android, the tools are backward compatible, so you need only one version of the SDK Platform-Tools.

     Downloads

     If you’re an Android developer, you should get the latest SDK Platform-Tools from Android Studio’s SDK Manager or from the sdkmanager command-line tool. This ensures the tools are saved to the right place with the rest of your Android SDK tools and easily updated.

     But if you want just these command-line tools, use the following links:

     • Download SDK Platform-Tools for Windows
     • Download SDK Platform-Tools for Mac
     • Download SDK Platform-Tools for Linux

     Although these links do not change, they always point to the most recent version of the tools.

     25.0.4 (March 16, 2017)

     • Added experimental libusb support to Linux and Mac adb

     To use the libusb backend, set the environment variable ADB_LIBUSB=true before launching a new adb server. The new adb host-features command will tell you whether or not you’re using libusb.

     To restart adb with libusb and check that it worked, use adb kill-server; ADB_LIBUSB=1 adb start-server; adb host-features . The output should include «libusb».

     In this release, the old non-libusb implementation remains the default.
