Wireless connection is useful when you can’t perform USB debugging, such as when using a ChromeOS device, when a controller is plugged into the Android device, or when debugging VRVirtual Reality More info
See in Glossary applications and you insert the Android device into the VR Kit. For information on how to connect a ChromeOS device to Unity through ADBAn Android Debug Bridge (ADB). You can use an ADB to deploy an Android package (APK) manually after building. More info
