I'm working through the step-by-step tutorial. I've created the "first game" successfully and run it on my PC and on my web page. Now I'm working on running it on my android phone. https://docs.godotengine.org/en/stable/getting_started/step_by_step/exporting.html

"When you run Android Studio for the first time, click on Configure -> SDK Manager and install "Android SDK Platform Tools". This installs the adb command-line tool that Godot uses to communicate with your device."

Apparently, I have to connect my phone to my PC when exporting? There are no more details about this, and I've never created a mobile app before. I'm not sure what to ask. Can you recommend a place online (or even a book) where I can better understand this process?

Connect via USB? When? Is there a way to create an .apk and download it to my phone later? Very confused. I haven't downloaded Android SDK or Open JDK yet. I want to have a better understanding of how this works first.

I have not watched either of these videos myself, but they seem to show the Godot to Android workflow:

Thank you. I'm checking it out.
