To build and run for Android, you must install the Unity Android Build Support platform module. You also need to install the Android Software Development Kit (SDK) and the Native Development Kit (NDK) to build and run any code on your Android device. By default, Unity installs a Java Development Kit based on.Note: Unity supports Android 4.4 “KitKat” and above. See for details. Install Android Build Support and the Android SDK & NDK toolsUse the Unity Hub to install Android Build Support and the required dependencies: Android SDK & NDK tools, and OpenJDK. Add Android modulesYou can install Android Build Support, the Android SDK & NDK tools and OpenJDK when you install the Unity Editor, or add them at a later time.For information on adding the Android modules:. At install time, see.

To an existing installation, see.Note: If you’re using Unity on macOS 10.15 (Catalina) and you don’t install Android tools through the Unity Hub, your operating system’s default security settings will prevent the Android NDK binaries being executed. You must either change these security settings, or download a signed Android NDK (r16b) from the.If you are using a 2018 version of Unity, see the for information on manually installing these dependencies. Enable USB debugging on your deviceTo enable USB debugging, you must enable Developer options on your device.

To do this, find the build number in your device’s Settings menu. The location of the build number varies between devices; for stock Android, it’s usually Settings About phone Build number. For specific information on your device and Android version, refer to your hardware manufacturer.After you navigate to the build number using the instructions above, tap on the build number seven times.

A pop-up notification saying “You are now X steps away from being a developer” appears, with “X” being a number that counts down with every additional tap. On the seventh tap, Developer options are unlocked.Note: On Android versions prior to 4.2 (Jelly Bean), the Developer options are enabled by default.Go to Settings Developer options (or, if this does not work, on some devices the path is Settings System Developer options), and check the USB debugging checkbox. Android now enters debug mode when it is connected to a computer via USB.Connect your device to your computer using a USB cable. If you are developing on a Windows computer, you might need to install a device-specific USB driver.

See the manufacturer website for your device for additional information.The setup process differs for Windows and macOS and is explained in detail on the Android developer website. For more information on connecting your Android device to the SDK, refer to the section of the Android Developer documentation. Customizing the Android SDK & NDK Tools and OpenJDK installationUnity recommends that you use the Unity Hub to install Android SDK & NDK tools, to ensure that you receive the correct versions and configuration. Unity installs Android SDK & NDK Tools and OpenJDK respectively in the SDK, NDK and OpenJDK folders under /Unity/Hub/Editor/EditorVersion/Editor/Data/PlaybackEngines/AndroidPlayer/.If you have multiple versions of Unity with the same required dependencies (be sure to check for the latest) and you want to avoid duplicating the installation of Android SDK & NDK Tools and OpenJDK, you can specify a shared location in the Unity Preferences window.

.RequirementsTo use the Xamarin Android SDK Manager, you will need the following:.Visual Studio 2019 Community, Professional, or Enterprise.OR Visual Studio 2017 (Community, Professional, or Enterprise edition). VisualStudio 2017 version 15.7 or later is required.Visual Studio Tools for Xamarin version 4.10.0 or later(installed as part of the Mobile development with.NET workload).The Xamarin Android SDK Manager also requires the Java Development Kit(which is automatically installed with Xamarin.Android).

There areseveral JDK alternatives to choose from:.By default, Xamarin.Android uses,which is required if you are developing for API level 24 or greater(JDK 8 also supports API levels earlier than 24).You can continue to useif you are developing specifically for API level 23 or earlier.If you are using Visual Studio 15.8 Preview 5 or later, you can tryusingrather than JDK 8.
