I get this error while connecting to  the emulator and it alway happening so now it impossible to update the companion

here the error

 App Inventor is unable to connect to the Android emulator. Please see this web page for help in dealing with this issue
I looked throught the web page and try everything there but i still got this error

It was working before until I accidently pressed Hard Reset and now i can't update the companion for it work again

Is there anything else i could do

[Scott Ferguson]

I think you need the latest AICompanion.apk to be reinstalled on the emulator.

Try opening the web browser on the emulator and navigating to this page: http://appinventor.mit.edu/explore/ai2/setup-device-wifi.html
There under the APK file barcode click the link text 'or click this link' to try installing it.

Reply here if that works.

to install the companion to the emulator, is it  the adb -e install -r companionfile method

[Enis]

Most of the emulator connection problems we have seen are a result of not having the most current version of the App Inventor setup software, or that software having been incompletely installed.

Still, there can be many other issues that could cause the connection to the emulator to fail.  Please read and follow the document below on connection issues:

Click here for Emulator Setup and Trouble Shooting Instructions

If you still cannot get the emulator running after following that document, please post in the forum and we'll try to help you out.

i said in a previous comment that i tried everything on the page and still got the error and follow the correct installion process

uninstall

reboot

install the setup package(i already have it download)

reboot

this is the installation process i use and i think it is the proper way

any other suggestions

[Hal Abelson]

I didn't see your previous comment, but did you do a hard reset?

[unknown]

yes, i accidently hard reset when it was working and now i have the problem

[Enis]

If you did a Hard Reset, then you have the early Companion on your Emulator.  The emulator should try to update itself.  Are you getting any Companion update notices?

[Enis]

You can try the adb thing... I think you did that before, but I remember that you were having issues because it was the Win 7 Starter edition.

Do you need some instructions on the adb apk installation thing again thing again???

[unknown]

nope i don't need the instruction again, i looked question where you gave me them but it seem not to work whenever the companion not on and it never reached the companion point, it also stop updating and giving the error in the first post. 

 

[Enis]

The companion must be on the Emulator... A hard reset actually returns the Emulator to it's original install state, with the original install companion for that setup set.

What version of the Companion is showing on the Emulator???

You CAN run the Companion on the emulator... just click on it.  But after doing so, you should "Reset Connection" because the software should start that when it tries to connect.

Run it and tell me what the version is please...

[unknown]

2.15ai2zx1 is my version

[Enis]

The current one is 2.16ai2zx1.

Does the emulator want to update that?  Are you getting messages that you need to update?  You should be...

the error  come right after the companion opens so it never  update because it stop connecting to the emulator right after  the companion opens

[unknown]

i cannot conect to port 8001 anymore since today, any suggestion of programs or firewall i should check first if it using the port 

[Andrew McKinney]

If you delete the companion from the emulator I have seen this problem. Doing a hard reset should reset everything back to the factory default meaning your .appinvemtor/emulator/emulator-user-data file is deleted. If you do a rest connection from the connect menu and run the emulator again it should work. However, you will need to update the companion on the emulator by following the directions given. This should get you back and running. If you still are having problems I would reinstall the setup tools, again you will need to update the companion, but should work afterwards. If you are still having problems please post again with information on the outcome of the above solutions.

ok now the companion works but  it said the activity update is not responding so that my problem now

[Andrew McKinney]

Thank you for the update on your issue. Just to clarify I image your situation is you have done the hard rest and are now trying to update the companion and you are getting an error message (a screenshot of the emulator would be very helpful to see) this seems that you cannot connect to the download server to get the updated companion. This is downloaded and then installed into the emulator. If it is failing at install then perhaps you are running out of space on your phone. Can you free up some space and try again? If this doesn't work please attach a screenshot to help us better diagnose your issue.
