Android studio intel x86 emulator

История о том, как запустить эмулятор Android или сэкономить на процессоре intel

Предыстория

Я собрал года 4 назад домашний комп, который подходил всем моим запросам. На процессоре решил сэкономить — взял amd. К компу вопросов нет.

Потом занялся разработкой под Android и тут меня ждал сюрприз! Эмулятор запускался только на процессоре intel. Его можно было запустить без аппаратной виртуализации конечно, используя вот этот совет www.youtube.com/watch?v=QTbjdBPKnnw&t=127s, но кто пользовался знает, что эмулятор может запускаться очень долго. У меня с 12ГБ доходило до 10 мин. Это может конечно из-за встроенной видеокарты.

Основное рабочее место у меня было в офисе, поэтому особо переживал и тестировал дома на реальных устройствах. Но пару месяцев назад стал нужен именно эмулятор. Первой мыслью было конечно купить intel-овский процессор. Но нужно было покупать ещё материнскую плату и видеокарту. Скорее всего я бы так и поступил, если бы не наткнулся на обновлённые требования к системе. В требованиях написано, что эмулятор всё таки можно запустить на Windows 10 (с обновлениями после апреля 2018) с помощью технологии WHPX.

Теперь основная часть истории, как это сделать. Всё оказалось не так тривиально. Заранее прошу прощения за упущения, потому что не могу назвать себя знатоком ни в “железе”, ни в Windows.

Инструкция

После всех обновлений эмулятор естественно не запустился. AndroidStudio пыталась запустить эмулятор с помощью HAXM и выбрасывала ошибку “Emulator: emulator: ERROR: x86 emulation currently requires hardware acceleration!”.

Далее приведу инструкцию с ссылками упустив кучу подробностей и моих “танцев с бубном”.

Должен поддерживать для работы с аппаратной виртуализацией.

2. Обновляем Windows 10 до версии 1803 (апрель 2018):

4. Включаем в bios режим виртуализации. Он там может называеться IOMMU, а не VT.

5. Качаем обновления для bios с официального сайта. Для моего asus, например, они были здесь.

Версия Bios должна стать что-то около 3001:

7. Заходим на сайт microsoft и изучаем инструкцию для включения компонента.

8. Нужно проверить требования Hyper-V. Для этого в командной строке набираем systeminfo. Проверяем, чтобы отображались эти значения:

У меня же вместо это было сообщение:

На официальном сайте написано, что пока не будет стоять Yes-Yes-Yes-Yes система WHPX не будет работать. У меня же эмулятор запускается, при включенной низкоуровневой оболочке.

9. Далее в руководстве предлагается включить компонент hyper-v (он по умолчанию отключен):

В русском переводе наименования несколько отличаются:

Кстати, после отключения компонента “Платформа низкоуровневой оболочки Windows”, “Требования hyper-v” становятся Yes-Yes-Yes-Yes. Не понял этот момент. Если кто разбирается, напишите в комментариях.

10. Определяем, нужно ли нам всё это? Или легче было купить intel)

После этих настроек всё должно заработать:

Хочу отметить, используя технологию WHPX и процессор amd, запуск эмулятора занимает примерно столько же времени, сколько на процессоре intel. Учитывая, что остальное «железо» сравнимо по своим параметрам.

Android studio intel x86 emulator

The Android Studio 2.0 (or higher) preview includes the new Android Emulator 2.0 with improved performance and a new user interface to control device features. This page describes some of the changes compared to the emulator available with the stable version of Android Studio 1.5 and how to setup your development environment to use the Android Emulator.

For best performance with Android Emulator 2.0, your system should meet the following specifications:

Windows: Intel® processor with support for Intel® VT-x, Intel® EM64T (Intel® 64), and Execute Disable (XD) Bit functionality. AMD and Intel Atom processors do not support VT-x virtual machine acceleration.

Linux: Intel® processor with support for Intel® VT-x, Intel® EM64T (Intel® 64), and Execute Disable (XD) Bit functionality or AMD processors with support for AMD Virtualization™ (AMD-V™)

64-bit Operating Systems.

New Features

The most valuable updates to the Android Emulator are the speed improvements. When running with Android Studio 2.0 or higher on an x86 machine, response time is faster than the previous Android Emulator and you can transfer files from your machine faster than a physical Android device.

The latest Android Emulator supports new multi-finger touch inputs, including pinch zoom and two finger rotate gestures. Holding down Alt or Option reveals two finger points. Moving the mouse moves one finger and the second finger is mirrored across an anchor point. Clicking the left mouse button enables pinch-zoom gestures and clicking the right mouse button enables two-finger rotate gestures (such as to tilt the perspective when viewing a map).

The panel on the right side of the emulator lets you perform common tasks, such as rotate the screen, capture screenshots, and zoom in on the display.

To install apps, you can drag and drop an APK right on the emulator. You can also drag and drop other file types and they’ll be saved to the /sdcard/Download/ directory.

At the bottom of the toolbar on the right is an ellipsis button that opens the Extended Controls window. In here you’ll find various controls that invoke device events and mock device sensors.

Keyboard shortcuts are available for most actions and are listed in the Help panel, listed on the left.

Get Android Emulator 2.0

The new Android Emulator is available with Android Studio 2.0 or higher, which is available in both the Stable, Beta and Canary channels .

Once you make sure you have the appropriate emulator system image and other tools:

Open the SDK Manager from Android Studio.

Click the SDK Platforms tab, and select the check box for a recent version such as the Android 6.0 (Marshmallow) . By default, this includes the x86 system image that you need for the emulator. You can see and modify the files to download by clicking Show Package Details at the bottom-right.

Click the SDK Tools tab, then select the check boxes for the following:

Android SDK Tools ( 25.0.0 or higher to get the new emulator)

Android SDK Platform-Tools (23.1.0 or higher to get the fast ADB)

Intel x86 Emulator Accelerator (HAXM installer) (rev 6.0.1 or higher to get CPU acceleration)

Click OK to check for updates.

Create new Android Virtual Device (AVD)

To take advantage of the new Android Emulator and adb speeds, you need to create new AVDs. In this example below, we are creating a Nexus 5x AVD.

Open the AVD Manager from Android Studio.

Click Create Virtual Device .

Select the defaults for Nexus 5x .

Select a system image, such as Marshmallow — API 23 — x86 .

Select Show Advanced Settings .

Select the Multi-Core CPU check box. The number of cores available depends on the number of cores available on your development machine.

Run your new Android Virtual Device by click on the green Play button.

You should see the Android Emulator now start up.

Troubleshooting

Check Intel x86 Emulator Accelerator Installation

If you selected the defaults during the Android Studio installation you should be ready to go. If you created a custom Android Studio installation or run into issues, read the troubleshooting guide below. If your Intel x86 Emulator Accelerator is out of date, Android Studio will automatically inform you and suggest a quick fix to update, as shown in the following screenshot in the AVD Manager.

Installing CPU Accelerator (HAXM)

If you skipped the initial setup of Android Studio, you should make sure the CPU acceleration is installed.

You can manually install Intel x86 Emulator Accelerator by opening intelhaxm-android.exe (on Windows) or intelHAXM_6.0.1.dmg (on Mac) from /sdk/extras/intel/Hardware_Accelerated_Execution_Mangager , as shown below:

Installing HAXM in Windows

Installing HAXM in OS X

For Linux, the Android emulator uses Kernel-based Virtual Machine (KVM). If you are using Ubuntu, you can run check your KVM system compatibility by running the following on the command line:

$egrep –c ‘(vmx|svm)’ /proc/cpuinfo

on the command line to check for for a return value of greater than 1

To check if you have KVM installed by running the following on the command line:

If KVM is missing or to ensure you have the latest KVM installed, run the following on the command line:

$sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils ia32-libs-multiarch

The linux commands look like the following on Ubuntu:

Known Issues
