Setting Up Android SDK and NDK for Unreal

How to set up your Android development environment for Unreal 4.25 and later

Choose your operating system:




Unreal Engine 4.25 and later uses the Android Software Development Kit (SDK) distributed with Android Studio for all essential Android development components, including the Android Native Development Kit (NDK) . This page provides a walkthrough for setting up Android Studio and ensuring that Unreal Engine recognizes these components correctly, and some troubleshooting tips for managing NDK installations and earlier engine builds.

Due to an update to the Android SDK Command-line Tools in February 2023, users on Unreal Engine 4.27 through 5.1 need to edit the SetupAndroid script used in this tutorial. If you are experiencing problems with NDK setup, refer to the section on setting up Command-Line Tools for Android for more details.

Recommended Setup

You should make sure that the Unreal Editor and the Epic Games Launcher are both closed to ensure that there are no problems with either the installation of NDK components or setting your environment variables for the engine.

If you are upgrading from Unreal 4.24 or earlier, we recommend that you uninstall CodeWorks for Android and any existing NDK components, and delete the folder CodeWorks was installed to. Otherwise, Android Studio will continue to use the previous CodeWorks installation folder for SDK updates.

The default installation directory for CodeWorks is C:/NVPACK . Make sure this folder is deleted when you finish uninstalling CodeWorks.

If you need to support an earlier installation of Unreal Engine while also maintaining an installation of Unreal 4.25 or later, refer to the sections on Manually Targeting SDK Paths and Android NDK Compatibility below.

1. Installing Android Studio

Before setting up the required SDK and NDK components on your computer, you need to install Android Studio .

Refer to Android Development Requirements for information about which Android Studio and NDK versions are compatible with your current version of Unreal Engine.

  1. Navigate to the Android Studio Archive in your web browser. Scroll down to Android Studio 4.0 , click to unfold the dropdown, and download the appropriate installer or zip file for your operating system.

    Click image for full size.

  6. In the Verify Settings dialog, check to make sure that you are using the default SDK path. Click Finish to finalize your setup and begin downloading components.

    Click image for full size.

    If you do not use the default SDK path, it is possible for SetupAndroid.bat to fail during a later step, as it will be unable to locate needed files.

  7. When components are finished downloading, click Finish again to end setup.

3. Set up Command-Line Tools for Android

Unreal Engine's Android SDK setup depends on Command-Line Tools for Android version 8.0 . Before moving on to finalize the installation, you need to make sure this version is installed and that UE's SetupAndroid script is targeting it correctly.

Originally, the SetupAndroid script targeted the Latest version, which referred to 8.0 . Due to an update in February 2023, Latest now refers to 9.0 , and you will need to re-target 8.0 manually if you are using a version of Unreal Engine that depends on it. This is required for UE 4.27, 5.0, and 5.1. The steps below take this into account and will walk you through fixing the SetupAndroid script.

  1. In the Welcome to Android Studio dialog, you will see a prompt in the lower-right corner asking to update your Android Studio to the latest version. Hover over it and dismiss it without updating. This will reveal the Configure and Get Help dropdowns.

  2. Open the Configure dropdown and click SDK Manager .

  3. In the Android SDK system settings, click the SDK Tools tab. This will display a list of optional components.

    Click image for full size.

  4. Check the box for Android SDK Command-line Tools version 8.0 . Click Apply to download and install this component.

  5. Click OK to dismiss the window and close the welcome dialog.

  6. Navigate to your Unreal Engine install directory -- for example, C:/Program Files/Epic Games/UE_4.27 .

  7. Open Engine/Extras/Android .

  8. Inside this directory, locate the SetupAndroid script appropriate for your operating system. SetupAndroid.bat is for Windows, SetupAndroid.command is for Mac, and is for Linux.

    Click image for full size.

  9. Open your operating system's SetupAndroid script in a text editor. Edit it as follows:

    • In SetupAndroid.bat , change any instance of set SDKMANAGER= to read: set SDKMANAGER=%STUDIO_SDK_PATH%\cmdline-tools\8.0\bin\sdkmanager.bat

    • In SetupAndroid.command or , change any instance of SDKMANAGERPATH= to read: SDKMANAGERPATH="$STUDIO_SDK_PATH/cmdline-tools/8.0/bin"

    Save the script and close your text editor.

    Make sure to edit every line that defines the SDKMANAGER or SDKMANAGERPATH variable, otherwise the Android NDK setup will fail.

4. Finalize the Android Studio Installation on Your OS

After completing all of the above steps, you need to finalize your installation to make sure your environment is fully set up before proceeding. Each operating system requires a different step to finalize installation.

Operating System

Required Action


Restart your computer.


Close your terminal window and reopen it.


Either close your terminal window and reopen it, or log out and log back in.

5. Setting Up Android NDK

With the necessary Android SDK components installed, you can use the SetupAndroid script to download and install the appropriate version of Android NDK.

  1. Navigate to your Unreal Engine 4 install directory -- for example, C:/Program Files/Epic Games/UE_4.27 .

  2. Open Engine/Extras/Android .

  3. Inside this directory, run the SetupAndroid script appropriate for your operating system. SetupAndroid.bat is for Windows, SetupAndroid.command is for Mac, and is for Linux.

    Click image for full size.

  4. You will be prompted to accept the Android SDK license agreement. Type Y and press Enter to accept.

    Click image for full size.

  5. When the installation completes, press any key to dismiss the command prompt.

  6. Restart your computer for all changes to take effect.

This script will download and install the required version of Android NDK for you in your Android home directory. The install directory for NDK should be C:/Users/[Username]/AppData/Local/Android/SDK/ndk/ , where "username" is your login name for your computer. You should see a folder containing the required NDK version.

In the event that you receive an error stating that repositories.cfg cannot be loaded, navigate to the folder where it is expected (usually C:/Users/[Username].android/repositories ) and create an empty repositories.cfg file. Android setup should then proceed normally.

If you receive an error stating that a package called lldb;3.1 could not be loaded, open the SetupAndroid script with a text editor, and locate the line of code that reads:

call "%SDKMANAGER%" "platform-tools" "platforms;android-28" "build-tools;28.0.3" "lldb;3.1" "cmake;" "ndk;21.1.6352462"

Remove the entry in this list for lldb;3.1 , but leave the others. This will enable setup to run normally. This issue is addressed in Unreal Engine 4.25.1 and later.

Manually Targeting SDK Paths

If you followed the above how-to sections without encountering problems, Unreal Engine will automatically associate the SDK paths for the Android SDK, the current Android NDK version, and the Java Development Kit (JDK). However, if you are using an earlier version of the Unreal Engine alongside Android Studio, you may need to manually target your SDK paths to be compatible. This is most likely to be the case if you have an installation of Unreal Engine alongside an earlier version that used CodeWorks.

Do not install CodeWorks and Android Studio at the same time, otherwise you will receive errors. If you need to support an earlier version of Unreal Engine alongside 4.25 or later, use the Android Studio setup in this document, then follow the instructions in this section to target the path for the version of Android Studio you need.

You can find the SDK paths by opening Edit > Project Settings , navigating to the Platforms > Android > Android SDK section.

Android Studio Setup

When these fields are left blank, they fall back on a set of default paths used by the installation process in the previous sections. If you have multiple installations of these components, or have installed them in non-standard directories, you can manually provide their paths here. Alternatively, you can open DefaultEngine.ini and provide them under the [/Script/AndroidPlatformEditor.AndroidSDKSettings] section.

SDKPath = (Path="C:\Filepath")
NDKPath = (Path="C:\Filepath")
JDKPath = (Path="C:\Filepath")

If the entries for SDKPath , NDKPath , and JDKPath do not exist in your DefaultEngine.ini, they will use the default path to the Android home directory.

Android SDK and NDK Compatibility

The following table shows which NDK and Android Studio versions are required or compatible with different versions of Unreal Engine.

Unreal Engine Version

Required Android Studio Version

Compatible NDK Versions

4.26.2 - 4.27
