Настройка Android SDK

Прежде чем вы сможете запустить написанный код на Android-устройстве, нужно выполнить несколько простых действий. Это относится как к работе с Unity, так и к созданию приложений с нуля.

1. Скачать Android SDK

Зайдите на страницу Android Developer SDK. Скачайте архив с последней версией Android SDK и распакуйте его.

2. Установить Android SDK

Следуйте инструкциям на странице Installing the SDK (причём, вы можете свободно пропустить опциональные части, относящиеся к Eclipse). В шаге 4 руководства Installing the SDK убедитесь, что добавили как минимум одну Android platform (Android платформу) с уровнем API равным или выше 9 (платформа 2.3 или выше), Platform Tools и USB drivers (USB драйверы), если вы используете Windows.

3. Удостовериться, что система определяет ваше устройство

Это может быть не так просто, особенно на Windows системах, в которых драйвера часто бывают источником проблем. Также, с вашим устройством может идти дополнительная информация или особые драйверы от производителя.

Для Windows: если Andoid устройство автоматически определяется системой, вам все равно придётся обновить драйверы на те, который поставляются с Android SDK. Это делается через диспетчер устройств Windows. —>Если устройство не определяется автоматически, используйте драйверы из Android SDK или особые драйверы, предоставленные производителем. —>Дополнительную информацию можно найти здесь: USB Drivers for Windows

Для Mac: если вы разрабатываете на OSX, тогда обычно не требуется никаких дополнительных драйверов.

Важно: Не забудьте включить “Отладку по USB” на вашем устройстве. Перейдите в Настройки -> Параметры разработчика , для включения отладки по USB. Начиная с Android Jelly Bean 4.2, параметры разработчика по умолчанию скрыты. Для их включения, понажимайте несколько раз пальцем на строку в меню Настройки -> Об устройстве -> Номер сборки . После этого вам станет доступен пункт Настройки -> Параметры разработчика .

Если вы не уверены, что ваше устройство корректно установилось в системе, пожалуйста, прочтите страницу Решение проблем при разработке под Android для дополнительной информации.

4. Добавить путь до Android SDK в Unity

При первой сборке проекта под Android (или если Unity не сможет обнаружить SDK), вас попросят указать местоположение папки, в которую вы установили Android SDK (вы должны выделить корневую папку установленного SDK). Путь до Android SDK также можно изменить в редакторе, выбрав в меню Unity > Preferences и перейдя в раздел External Tools окна настроек.

Android SDK/NDK setup

Whether you’re building an Android application in Unity or programming it from scratch, you need to set up the Android Software Development Kit (SDK) before you can build and run any code on your Android device.

1. Download the Android SDK

Download the Android SDK from the Android Studio and SDK Tools download page. You can either use an Android Studio and SDK bundle, or only download the SDK command line tools.

2. Install the Android SDK

Install or unpack the Android SDK. After installing, open the Android SDK Manager and add at least one Android SDK Platform, the Platform Tools, the Build Tools, and the USB drivers if you’re using Windows.

3. Enable USB debugging on your device

To enable USB debugging, you need to enable Developer options. To do this, find the build number in your device’s Settings menu. The location of the build number varies between devices. The stock Android setting can be found by navigating to Settings > About phone > Build number. For different devices and Android versions, refer to your hardware manufacturer.

Note: On operating systems older than Android 4.2 (Jelly Bean), the Developer options aren’t hidden. Go to Settings > Developer options, then enable USB debugging.

After you have navigated 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. Go to Settings > Developer options, and check the USB debugging checkbox to enable debug mode when the device is connected to a computer via USB.

4. Connect your Android device to the SDK

Connect your Android device to your computer using a USB cable. If you are developing on a Windows computer, you need to install the appropriate USB driver for your device.

For more information on connecting your Android device to the SDK, refer to the Running Your App section of the Android Developer documentation.

5. Configure the Android SDK path in Unity

The first time you make a Project for Android (or if Unity later fails to locate the SDK), you will be asked to locate the folder where you installed the Android SDK. Select the root folder of your SDK installation. If you wish to change the location of the Android SDK, in the menu bar go to Unity > Preferences > External Tools.

6. Download and set up the Android NDK

If you are using the IL2CPP scripting back end for Android, you need the Android Native Development Kit (NDK). It contains the toolchains (such as compiler and linker) needed to build the necessary libraries, and finally produce the output package (APK). If you are not targeting the IL2CPP back end, you can skip this step.

Download the Android NDK version required by Unity from the NDK Downloads web page, and then extract it to a directory. The first time you build a project for Android using IL2CPP, you will be asked to locate the folder where you installed the Android NDK. Select the root folder of your NDK installation. If you wish to change the location of the Android NDK, in the Unity Editor, navigate to menu: Unity > Preferences… to display the Unity Preferences dialog box. Here, click External Tools.

Android environment setup

Whether you’re building an Android application in Unity or programming it from scratch, you must set up the Android Software Development Kit (SDK) before you can build and run any code on your Android device. By default, Unity installs a Java Development Kit based on OpenJDK.

1. Download the Android SDK

You can install the Android SDK using command line tools or through Android Studio. Android Studio provides an easy to use GUI based tool but installs additional software on your computer. Using the command line tools is a smaller download and does not install additional software, but it can be more challenging to use.

1a. Install the Android SDK using the command line tools

Install or unpack the Android SDK. After installing, open the Android SDK Manager and add at least one Android SDK Platform, the Platform Tools, the Build Tools, and the USB drivers if you’re using Windows.

To install an Android platform SDK and the associated tools:

Unzip the tools folder to a location on your hard drive.

Open a command-prompt window.

Navigate to the bin folder in the location where you unzipped the tools folder:

install folder > tools > bin

Use the sdkmanager command line tool to retrieve the list of packages that you can install. The installable packages include the Platform SDKs, Build Tools, Platform tools, and other tools.

Select a version of the Platform SDK to install. Platform SDKs take the following form in the list: platforms;android-xx. The xx indicates the SDK level. The larger the number, the newer the package. Typically, you can install the latest available version. However, there might be cases where Google has released a new version of the SDK that causes errors when you build your Unity Project. In that case, you must uninstall the SDK and install an earlier version. The general format of the command for package installation is sdkmanager

. You can install the corresponding Platform Tools and Build Tools at the same time.

Example: sdkmanager “platform-tools” “platforms;android–27” “build-tools;27.0.3”

1. If you are running on Windows, install the USB device drivers:

This installs the SDK to a directory named platforms in the same directory you unzipped the tools folder to.

c: \platforms

1b. Install the SDK using Android Studio

Install Android studio from the Android developer portal. The Android developer portal provides detailed installation instructions.

Note: Android Studio provides some ease of use benefits, but it is not fully tested for compatibility with Unity installs. If you encounter errors, Unity recommends using the command line method.

When installing the Android platform SDK and other tools, you can typically install the latest available version. There might be cases in which Google has released a new version of the SDK that causes errors when you build your Unity Project. In that case, uninstall the SDK and install an earlier version.

Install the associated Platform and Build tools at the same time. If you are running on Windows, install the USB device drivers.

2. Enable USB debugging on your device

To enable USB debugging, you must first 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 in 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, then enable USB debugging. 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 the device-specific USB driver. See the manufacture 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 Running Your App section of the Android Developer documentation.

3. Configure the Android SDK path in Unity

The first time you create a Project for Android (or if Unity later fails to locate the SDK), Unity asks you to locate the folder in which you installed the Android SDK.

If you installed the SDK using the sdkmanager, you can find the folder in \platforms .

If you installed the SDK when you installed Android Studio, you can find the location in the Android Studio SDK Manager. To open the SDK Manager from Android Studio, go to Tools > Android > SDK Manager or select SDK Manager in the toolbar.

To change the location of the Android SDK, in the Unity menu bar go to Unity > Preferences > External Tools.

4. Download and set up the Android NDK

If you are using the IL2CPP scripting backend for Android, you need the Android Native Development Kit (NDK). It contains the toolchains (such as compiler and linker) needed to build the necessary libraries and produce the output package (APK). If you are not targeting the IL2CPP backend, you can skip this step.

Download Android NDK version r16b (64-bit) from the NDK Downloads web page. Extract the android-ndk-r16b folder to a directory on your computer and note the location.

The first time you build a Project for Android using IL2CPP, Unity asks you to locate the folder in which you installed the Android NDK. Select the root folder of your NDK installation. To change the location of the Android NDK, in the Unity Editor, navigate to the menu: Unity > Preferences to display the Unity Preferences dialog box. Here, click External Tools.

Using an alternate Java Development Kit

Unity recommends that you use the JDK installed with the Android build tools, to ensure that you receive the correct version and configuration.

If you have manually installed the JDK and do not want to duplicate the installation, you can specify the location in the Unity Preferences window. To do this, go to Preferences > External tools and enter the directory path in the JDK field:

Preferences for Android external tools

Warning: The Android tools do not support JDK 9 or later; an alternate JDK must be version 8. Unity does not officially support versions of the JDK other than the one embedded in the Android Build Tools.

To change the JDK that Unity uses to build Android apps:

Open the Project.

In the left navigation column, select External Tools.

Uncheck JDK Installed with Unity (recommended).

In the JDK field enter the path to the JDK or use the Browse button to locate it.

Android SDK Setup

Whether you’re building an Android application in Unity or programming it from scratch, you need to set up the Android SDK (software development kit) before you can build and run any code on your Android device.

1. Download the Android SDK

On your PC, go to the Android Developer SDK website. Download and unpack the latest Android SDK.

2. Install the Android SDK

Follow the instructions in Installing the SDK. You can skip the optional sections relating to Eclipse. In step 4 of Installing the SDK, be sure to add at least one Android platform with API level equal to or higher than 9 (Platform 2.3 or greater), the Platform Tools, and the USB drivers if you’re using Windows.

3. Enable USB debugging on your device

USB debugging is a useful way to debug while connecting your Android device to the SDK, so get this set up before moving on to the next step.

To enable USB debugging, you first need to enable Developer options. To do this, navigate your phone to the “Build number” portion in your device’s Settings. Finding it can be different depending on the device:

• Stock Android: Settings >About phone >Build number
• Samsung Galaxy S5: Settings >About device >Build number
• LG G3: Settings >About phone >Software information >Build number
• HTC One (M8): Settings >About >Software information >More >Build number

Note: On operating systems older than version 4.2 (Jelly Bean), the Developer options aren’t hidden. Go to Settings > Developer options, then enable USB debugging.

Navigate to Build number using the instructions above. Tap on the build number 7 times. A small pop-up notification appears saying “you are now X steps away from being a developer” with a number that counts down with every additional tap. On the 7th tap, Developer options are unlocked. Go to Settings > Developer options, and check the USB debugging checkbox to enable debug mode when the device is connected to a computer via USB.

4. Connect your Android device to the SDK

This can be tricky, especially under Windows-based systems where drivers tend to be a problem. Your device may come with additional information or specific drivers from the manufacturer.

• Windows: If the Android device is automatically recognized by the system you still might need to update the drivers with the ones that came with the Android SDK. You can do this through the Windows Device Manager. If the device is not recognized automatically, use the drivers from the Android SDK, or any specific drivers provided by the manufacturer. Find further information regarding USB Drivers for Windows on the Android Developer page.
• Mac: If you’re developing on macOS, you usually don’t need any additional drivers.

If you are unsure whether your device is properly installed on your system, please read the Android development troubleshooting page for details.

5. Add the Android SDK path to Unity

The first time you build a project for Android (or if Unity later fails to locate the SDK), you will be asked to locate the folder where you installed the Android SDK. Select the root folder of the SDK installation. If you wish to change the location of the Android SDK, in the menu bar go to Unity > Preferences, then click External Tools.
