Android studio downloading components

Install and configure the NDK and CMake

To compile and debug native code for your app, you need the following components:

• The Android Native Development Kit (NDK): a set of tools that allows you to use C and C++ code with Android.
• CMake: an external build tool that works alongside Gradle to build your native library. You do not need this component if you only plan to use ndk-build.
• LLDB: the debugger Android Studio uses to debug native code. By default, LLDB will be installed alongside Android Studio.

This page describes how to install these components automatically, or by using Android Studio or the sdkmanager tool to download and install them manually.

Install NDK and CMake automatically

Android Gradle Plugin 4.2.0+ can automatically install the required NDK and CMake the first time you build your project if their licenses have been accepted in advance. If you’ve already read and agree to the license terms, then you can pre-accept the licenses in scripts with the following command:

Install the NDK and CMake

When you install the NDK, Android Studio selects the latest available NDK. For most projects, installing this default version of the NDK is sufficient. If your project needs one or more specific versions of the NDK, though, you can download and configure specific versions. Doing so helps you ensure reproducible builds across projects that each depend on a specific version of the NDK. Android Studio installs all versions of the NDK in the android-sdk /ndk/ directory.

To install CMake and the default NDK in Android Studio, do the following:

With a project open, click Tools > SDK Manager.

Click the SDK Tools tab.

Select the NDK (Side by side) and CMake checkboxes.

Figure 1: The SDK Tools window showing the NDK (Side by side) option

Click OK.

A dialog box tells you how much space the NDK package consumes on disk.

Click OK.

When the installation is complete, click Finish.

Your project automatically syncs the build file and performs a build. Resolve any errors that occur.

Configure a specific version of CMake

The SDK Manager includes the 3.6.0 forked version of CMake and version 3.10.2. Projects that don’t set a specific CMake version are built with CMake 3.10.2. To set the CMake version, add the following to your module’s build.gradle file:

Groovy

Kotlin

If you want to use a CMake version that is not included by the SDK Manager, follow these steps:

1. Download and install CMake from the official CMake website.
2. Specify the CMake version you want Gradle to use in your module’s build.gradle file.

Either add the path to the CMake installation to your PATH environment variable or include it in your project’s local.properties file, as shown. If Gradle is unable to find the version of CMake you specified in your build.gradle file, you get a build error.

If you don’t already have the Ninja build system installed on your workstation, go to the official Ninja website, and download and install the latest version of Ninja available for your OS. Make sure to also add the path to the Ninja installation to your PATH environment variable.

Install a specific version of the NDK

To install a specific version of the NDK, do the following:

With a project open, click Tools > SDK Manager.

Click the SDK Tools tab.

Select the Show Package Details checkbox.

Select the NDK (Side by side) checkbox and the checkboxes below it that correspond to the NDK versions you want to install. Android Studio installs all versions of the NDK in the android-sdk /ndk/ directory.

Figure 2: The SDK Tools window showing the NDK (Side by side) options

Click OK.

A dialog box tells you how much space the NDK package(s) consumes.

Click OK.

When the installation is complete, click Finish.

Your project automatically syncs the build file and performs a build. Resolve any errors that occur.

Configure each module with the version of the NDK you want it to use. When using Android Studio 3.6 or higher, if you do not specify the version, the Android Gradle plugin chooses a version that it is known to be compatible with.

Configure specific versions of the NDK in your project

You may need to configure the version of the NDK in your project if one of the following is true:

Your project is inherited and you need to use specific versions of the NDK and the Android Gradle plugin (AGP). For more information, see Configure the NDK for the Android Gradle plugin.

You have multiple versions of the NDK installed and you want to use a specific one. In this case, specify the version using the android.ndkVersion property in the module’s build.gradle file, as shown in the following code sample.

Groovy

Kotlin

Default NDK version per AGP version

Before release, each AGP version is thoroughly tested with the latest stable NDK release at that time. For AGP version 3.6 and above, that NDK version will be used to build your projects if you do NOT specify an NDK version in the build.gradle file. The default NDK version is documented inside the AGP release notes. The current default NDK versions are listed in the following table:

Android Studio/Gradle Plugin Version
7.0	4.2	4.1	4.0	3.6	3.5	3.4
Default NDK version specified for the version of AGP	21.4.7075529	21.4.7075529	21.1.6352462	21.0.6113669	20.0.5594570	No default specified

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.
