An alternative to Build and Run is to just build the APK Android app file and then sideload it to the Android device.
For this, you can use a USB cable and either of the following:
- The Android File Transfer app: https://www.android.com/filetransfer/T.
- The command-line Android Debug Bridge (ADB). You can find a good ADB tutorial here: https://androidcommunity.com/how-to-getting-adb-on-your-pc-without-installing-full-android-sdk-20180307/.
Once you've transferred the APK file to the Quest/Android device, you can install and run the app.
