Followed this. I ran it on my avd and it says, “The license key specified is invalid.” Okay I literally copy and pasted the license key from my email into the method. OKAY ALSO IF I PASTE CODE I CANNOT CLICK TO THE BOTTOM OF THE CODE AND CONTINUE TYPING. I AM STUCK IN THE CODE EDITOR.

Hi @Jesse Hu, I am having someone look at it right now for you. I’ll respond shortly. Thanks for your patience.
Are you using your engine trial license key instead of the Gocoder SDK key? The Engine Developer key usually starts with EDEV4 and that is not the one to insert there. Can you try your SDK license key?
I replaced it with the SDK license key and now it crashes.
The only thing to do at this point is open a support ticket and have us run full tests on your log files to find the issue. I’m sorry I wasn’t able to resolve it for you here in the forums. We just need to take a closer look at everything and the engineers only do that through tickets. Thanks for your communication with me.
