MIT App Inventor Issue (using Companion)

Gopa_Samal · March 4, 2021, 3:00pm

Hello,

I wanted to test my app in companion but, it didn't start processing and not connecting. And I have tried Emulator and USB connection also.
How do I test it?

Did you follow the advice

Gopa_Samal · March 4, 2021, 3:08pm

@SteveJG I have followed all of these advices before making the 1st app with App Inventor.

SteveJG · March 4, 2021, 3:23pm

You realize we cannot see what you have done Gopa.

I expect you missed a step.

Did you install the App Inventor Companion App on your device?

Did you ever see this Screen

Do you have a Project loaded?

Gopa_Samal · March 4, 2021, 3:26pm

I have installed the app. And the right hand side screen opens in the app. I have tried the both options
"Scan QR Code" & "connect with code".

...and what happens? What do you see after you Scan QR Code?

Gopa_Samal · March 4, 2021, 4:02pm

After that it shows Processing and stuck at 20%.

The same thing happens to me.
Stop in 20 Establishing secure connection in Chrome. it works for me with Firefox.

I had the same issue. I changed to chrome and just works fine.

Gopa_Samal · March 4, 2021, 4:07pm

It worked in Firefox

SteveJG · March 4, 2021, 4:09pm

This appears to be an issue involving latency in your ISP. Check the Use Legacy check box on your Companion screen before you use the QR Code and Chrome will work without getting stuck at 20%

@jis there seems to be an issue w.r.t. Chrome affecting multiple users (including me).

Gopa_Samal · March 4, 2021, 4:11pm

Yes it worked in chrome with the true value in Use Legacy

SteveJG · March 4, 2021, 4:13pm

Thanks for letting us know. Glad Chrome and Companion are working for you now. MIT will be informed there is a new issue w.r.t. using Chrome.

Juan_Antonio · March 4, 2021, 4:19pm

Now it works. The error was given to me in Chrome with the Companion App Inventor and Kodular.

i have some problem
can tell me how to fix it
the progerss still stop at 20%

SteveJG · March 5, 2021, 2:58pm

If you are using Chrome @terry23462016 you can try this advice:

What happens if you Check Use Legacy on your Companion before pressing QR Code?

terry23462016 · March 5, 2021, 4:30pm

i try to use aiStarter , it can work
but if i use nox or bluestack even i check use legacy , it still not work

SteveJG · March 5, 2021, 4:43pm

If you use Companion with a real android, can you live develop using Chrome if you check the Use Legacy box? This is the problem other users are having.

You say you are having issues accessing nox and Bluestack emulators which I think are accessed using Companion.

Good the basic emulator works . Regarding nox or bluestack, sorry, I can not help you with these third party emulators.
Perhaps @ABG will have some ideas and post here his thoughts.

Same problem with Brave browser.
Ok with Chrome
