Learn how to set up the Android Emulator to test your app on a virtual Android device.
If you don't have an Android device available to test with, we recommend using the default emulator that comes with Android Studio. If you run into any problems setting it up, follow the steps in this guide.
Download and install Android Studio.
Open the Android Studio app, click More Actions and select SDK Manager.
Open Android Studio, go to Settings > Languages & Frameworks > Android SDK. From the SDK Platforms tab, select the latest Android version (API level).
Then, click on the SDK Tools tab and make sure you have at least one version of the Android SDK Build-Tools and Android Emulator installed.
Copy or remember the path listed in the box that says Android SDK Location.
Click Apply and OK to install the Android SDK and related build tools.
If you are on macOS or Linux, add an environment variable pointing to the Android SDK location in ~/.bash_profile (or ~/.zshrc if you use Zsh). For example:
Add the following lines to your /.zprofile or ~/.zshrc (if you are using bash, then ~/.bash_profile or ~/.bashrc) config file:
Reload the path environment variables in your current shell:
# for bash
# for zsh
Finally, make sure that you can run
adb from your terminal.
Download Android Studio.
Open Android Studio Setup. Under Select components to install, select Android Studio and Android Virtual Device. Then, click Next.
In the Android Studio Setup Wizard, under Install Type, select Standard and click Next.
The Android Studio Setup Wizard will ask you to verify the settings, such as the version of Android SDK, platform-tools, and so on. Click Next after you have verified.
In the next window, accept licenses for all available components.
After the tools installation is complete, configure the
ANDROID_HOME environment variable. Go to Windows Control Panel > User Accounts > User Accounts (again) > Change my environment variables and click New to create a new
ANDROID_HOME user variable. The value of this variable will point to the path to your Android SDK:
By default, the Android SDK is installed at the following location:
To find the location of the SDK in Android Studio manually, go to Settings > Languages & Frameworks > Android SDK. See the location next to Android SDK Location.
To verify that the new environment variable is loaded, open PowerShell, and copy and paste the following command:
Get-ChildItem -Path Env:
The command will output all user environment variables. In this list, see if
ANDROID_HOME has been added.
To add platform-tools to the Path, go to Windows Control Panel > User Accounts > User Accounts (again) > Change my environment variables > Path > Edit > New and add the path to the platform-tools to the list as shown below:
By default, the platform-tools are installed at the following location:
Finally, make sure that you can run
adb from the PowerShell. For example, run the
adb --version to see which version of the
adb your system is running.
On the Android Studio main screen, click More Actions, then Virtual Device Manager in the dropdown.
Click the Create device button.
Under Select Hardware, choose the type of hardware you'd like to emulate. We recommend testing against a variety of devices, but if you're unsure where to start, the newest device in the Pixel line could be a good choice.
Select an OS version to load on the emulator (probably one of the system images in the Recommended tab), and download the image.
Change any other settings you'd like, and press Finish to create the virtual device. You can now run this device anytime by pressing the Play button in the AVD Manager window.
adb versions on your system can result in the following error:
adb server version (xx) doesn't match this client (xx); killing...
This is because the
adb version on your system is different from the
adb version on the Android SDK platform-tools.
Open the terminal and check the
adb version on the system:
And from the Android SDK platform-tool directory:
adb from Android SDK directory to
sudo cp ~/Library/Android/sdk/platform-tools/adb /usr/bin
