I have Hyper-V VM set up with android. WIFI is not an option within Android, and I dont have WIFI hardware in my PC, which is wired.
Android uses my host wired internet connection.
I've installed AI Companion on the client VM, however it does nothing when I enter a 6-character code to connect to my app.

I have aistarter installed with the classic emulator, which is unreliable and very slow.

Can I configure aistarter to use my Hyper-V Android VM instead?
Or alternatively trick my VM into using the wired connection as a WIFI connection?

I'm a lecturer with a class of students using App Inventor and were having massive headaches testing with the generic emulator.

some have android mobiles, others don't.

Our resident techies have said use Hyper-V, as its already available, rather than trying to get approval for something else.
The class finishes in early June so battling with college IT to get software is off the cards.

Any advice?

Thanks in advance,

Chris Ward

Hello Al

MIT released a new  App Inventor version today, nb176 - it includes a very much improved emulator, so I think it would be good to check that out first?

The link to a Windows setup file from nb176 still presents a version 2.3.0 in its file name,
so I think only the Companion has changed, not the underlying emulator.

The Power Users group has a new windows emulator under test, at

but the release notes and testing results are in the Power Users thread.

I have attached a dead pdf print of that thread.

There are also GenyMotion setup instructions in the 
Companion and Emulator section of FAQ
(the critical steps are copying over the emulator's adb.exe onto MIT's adb.exe
 then connecting via the virtual USB menu option.)
Those instructions might work with your emulator.

@ Chris  ... the Windows emulator PU's are testing is not available to most users.  The test emulator is NOT officially released for general use.  You see it because you are testing it.  Unfortunately the test Windows emulator still has serious bugs, among them, it does not automatically update the Companion. Evan posted a 64 bit emulator version just now.  What we got was a 32 bit Companon for the test emulator...haven't tested with the 64 bit version of Companion 2.52 yet.

@ Others .... the Windows test emulator is buggy.  Please only use the aiTest standard emulator until the test emulator is officially released.  Thanks.

Hi guys,

thanks for your input.

Our techies here have just taken hyper-v off the table. I'm not allowed to enable it in our class rooms due to security concerns.

I'm now looking at implementing android studio emulators, but that`s probably another thread.

Thanks again.
