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.

## Set up Android Studio's tools

<Step label="1">

[Download](https://developer.android.com/studio) and install Android Studio.

</Step>

<Step label="2">

Open the **Android Studio** app, click **More Actions** and then select **SDK Manager**.

</Step>

<Step label="3">

Open Android Studio, go to **Settings** &gt; **Languages & Frameworks** &gt; **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.

/>
</Step>

<Step label="4">
Copy or remember the path listed in the box that says **Android SDK Location**.

<ImageSpotlight
  alt="Android SDK location."
  src="/static/images/android-studio/sdk-location.png"
/>
</Step>

<Step label="5">

Click **Apply** and **OK** to install the Android SDK and related build tools.

</Step>

<Step label="6">

If you are on macOS or Linux, add an [environment variable](https://developer.android.com/studio/command-line/variables#envar) pointing to the Android SDK location in **~/.bash_profile** (or **~/.zshrc** if you use Zsh). For example: `export ANDROID_HOME=/your/path/here`.

Add the following lines to your **/.zprofile** or **~/.zshrc** (if you are using bash, then **~/.bash_profile** or **~/.bashrc**) config file:

<Terminal
  cmd={[
    'export ANDROID_HOME=$HOME/Library/Android/sdk',
    'export PATH=$PATH:$ANDROID_HOME/emulator',
    'export PATH=$PATH:$ANDROID_HOME/platform-tools',
  ]}
  cmdCopy="export ANDROID_HOME=$HOME/Library/Android/sdk && export PATH=$PATH:$ANDROID_HOME/emulator && export PATH=$PATH:$ANDROID_HOME/platform-tools"
/>

</Step>

<Step label="7">

Reload the path environment variables in your current shell:

<Terminal cmd={['# for bash', 'source $HOME/.bashrc', '', '# for zsh', 'source $HOME/.zshrc']} />

</Step>

<Step label="8">

Finally, make sure that you can run `adb` from your terminal.

</Step>

## Set up a virtual device

<Step label="1">
On the Android Studio main screen, click **More Actions**, then **Virtual Device Manager** in the dropdown.

<ImageSpotlight
  alt="Android Studio configure."
  src="/static/images/android-studio/virtual-device.png"
  containerStyle={{ paddingBottom: 0 }}
/>

</Step>

<Step label="2">

Click the **Create device** button.

<ImageSpotlight
  alt="Android Studio create virtual device."
  src="/static/images/android-studio/create-device.png"
  containerStyle={{ paddingBottom: 0 }}
/>

</Step>

<Step label="3">

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.

<ImageSpotlight
  alt="Android Studio create virtual device hardware selection."
  src="/static/images/android-studio/select-hardware.png"
  containerStyle={{ paddingBottom: 0 }}
/>

</Step>

<Step label="4">

Select an OS version to load on the emulator (probably one of the system images in the **Recommended** tab), and download the image.

<ImageSpotlight
  alt="Android Studio create virtual device os selection."
  src="/static/images/android-studio/select-os.png"
  containerStyle={{ paddingBottom: 0 }}
/>

</Step>

<Step label="5">

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.

</Step>

### Multiple `adb` versions

Having multiple `adb` versions on your system can result in the following error:

<Terminal cmd={["$ 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.

<Step label="1">
Open the terminal and check the `adb` version on the system:

<Terminal cmd={['$ adb version']} />
</Step>

<Step label="2">
And from the Android SDK platform-tool directory:

<Terminal cmd={[
  '$ cd ~/Library/Android/sdk/platform-tools',
  '$ ./adb version'
]} cmdCopy="cd ~/Library/Android/sdk/platform-tools && ./adb version" />
</Step>

<Step label="3">
Copy `adb` from Android SDK directory to `usr/bin` directory:

<Terminal cmd={['$ sudo cp ~/Library/Android/sdk/platform-tools/adb /usr/bin']} />
</Step>
