We recommend the Genymotion emulator over the Android Studio emulator. If you run into any problems using Genymotion, follow the steps in this guide.

Genymotion and XDE/exp both bundle their own versions of the Android tools. In order for XDE or exp to communicate with Genymotion they need to share the same set of tools. You can do this by either telling XDE/exp to use Genymotion's tools, or by installing Android Studio and telling both XDE/exp and Genymotion to use the tools from Android Studio.
Choose one of these two options:

  • Install Android Studio.
  • Go to Configure -> SDK Manager.
Configure SDK
  • In SDK Manager, make sure you are in Appearance & Behaviour -> System Settings -> Android SDK. Your SDK and tools are in the box that says Android SDK Location. Remember this location!
Android SDK location
  • If you are on macOS or Linux, add the Android SDK location to your PATH using ~/.bash_profile or ~/.bash_rc.
  • On macOS, you will also need to add platform-tools to your ~/.bash_profile or ~/.bash_rc., by adding a line like export PATH=/Users/myuser/Library/Android/sdk/platform-tools:$PATH
  • Make sure that you can run adb from your terminal.
  • Open Genymotion and navigate to Settings -> ADB. Select "Use custom Android SDK tools" and update with your Android SDK location:
  • Start Genymotion

  • Find Genymotion's copy of adb. On macOS this is normally /Applications/Genymotion.app/Contents/MacOS/tools/.
  • Add the Genymotion tools directory to your path.
  • Make sure that you can run adb from your terminal.

Run npm install -g exp to install exp globally.
Then run exp path. This will save your PATH environment variable so that XDE knows where to find your Android tools.
