I had a question about using Android Studio with an external hard drive on Windows 10. If I copy a full android project from my computer to the hard drive can I access the project from the hard drive if I delete the file from the computer itself (With hard drive still plugged in)?
For My experience never delete original project you will needed at some point.
Yes you can access the project from the hard drive In Android Studio by Clicking File > Open select your drive and look for your file.
You will always able to see the project location it is Running from.
