In the following section you will go over all you need to know to set up your Android device so that it can be used to run your Unreal Engine (UE) project.
1. Installing Android USB Drivers to Your Computer

Connect your Android device to your development PC via USB.
-
Your device driver software should automatically install. If not, visit Android's OEM USB Drivers page to find more driver installation links and additional information.

4. Verifying That Your Device is Connected
To verify that everything has been setup correctly and that your Android device is ready for Unreal Engine development, you can do the following:
-

If you still do not see your device after you input the adb devices command you can try the following items:
-
If the device is listed but shows Unauthorized next to the name, that indicates that you did not accept your development PC's computer's RSA key fingerprint.
-
If your device does not show up despite it being plugged in and setup, input the following commands in the following order into the Windows Command Prompt to restart the Android Debug Bridge or (ADB) service:
Property Name Description ADB kill - server This will stop the ADB service. ADB start - server This will start the ADB service. -
