Android Virtual Device | AVD by Android Studio | Virtual Android | Latest Android Version | ViewSoft
The Android Emulator simulates Android devices on your computer so that you can test your application on a variety of devices and Android API levels without needing to have each physical device.
The emulator provides almost all of the capabilities of a real Android device. You can simulate incoming phone calls and text messages, specify the location of the device, simulate different network speeds, simulate rotation and other hardware sensors, access the Google Play Store, and much more.
Testing your app on the emulator is in some ways faster and easier than doing so on a physical device. For example, you can transfer data faster to the emulator than to a device connected over USB.
The emulator comes with predefined configurations for various Android phone, tablet, Wear OS, and Android TV devices.
The Android Emulator has additional requirements beyond the basic system requirements for Android Studio, which are described below:
SDK Tools 26.1.1 or higher
64-bit processor
Windows: CPU with UG (unrestricted guest) support
HAXM 6.2.1 or later (HAXM 7.2.0 or later recommended)
The use of hardware acceleration has additional requirements on Windows and Linux:
Intel processor on Windows or Linux: Intel processor with support for Intel VT-x, Intel EM64T (Intel 64), and Execute Disable (XD) Bit functionality
AMD processor on Linux: AMD processor with support for AMD Virtualization (AMD-V) and Supplemental Streaming SIMD Extensions 3 (SSSE3)
AMD processor on Windows: Android Studio 3.2 or higher and Windows 10 April 2018 release or higher for Windows Hypervisor Platform (WHPX) functionality
To work with Android 8.1 (API level 27) and higher system images, an attached webcam must have the capability to capture 720p frames.
Run an app on the Android Emulator------
You can run an app from an Android Studio project, or you can run an app that's been installed on the Android Emulator as you would run any app on a device.
To start the Android Emulator and run an app in your project:
In Android Studio, create an Android Virtual Device (AVD) that the emulator can use to install and run your app.
In the toolbar, select the AVD that you want to run your app on from the target device drop-down menu.
If you receive an error or warning message at the top of the dialog, click the link to correct the problem or to get more information.
Some errors you must fix before you can continue, such as certain Hardware Accelerated Execution Manager (Intel HAXM) errors.
For macOS, if you see a Warning: No DNS servers found error when starting the emulator, check to see whether you have an /etc/resolv.conf file. If you don't have this file, enter the following command in a terminal window:
Launch the Android Emulator without first running an app
To start the emulator:
Open the AVD Manager.
Double-click an AVD, or click Run
Run icon.
The Android Emulator loads.
While the emulator is running, you can run Android Studio projects and choose the emulator as the target device. You can also drag one or more APKs onto the emulator to install them, and then run them.
Install and add files
To install an APK file on the emulated device, drag an APK file onto the emulator screen. An APK Installer dialog appears. When the installation completes, you can view the app in your apps list.
To add a file to the emulated device, drag the file onto the emulator screen. The file is placed in the /sdcard/Download/ directory. You can view the file from Android Studio using the Device File Explorer, or find it from the device using the Downloads or Files app, depending on the device version.
