ERROR 1103!!

[Trerut3]

Hi. 
I am using an android tablet and I have used it before to test my app and it has always come up with error 1103 and let me test my app. However, I tried to test it again today and it says error 1103 and then doesn't let me into the app I'm testing.

Hi, 

Are you experiencing this error with the Companion app or a compiled apk of your own? Are other apps having this problem? Other tablets/phones?

If you are seeing this error in the Companion, it likely means that your tablet cannot communicate with our "rendezvous" server located at rendezvous.appinventor.mit.edu. Something on your network is likely blocking the needed request.

This is on the companion app on an android tablet. I can't test it on any other devices because I have none.

probably because I'm using a school network for testing. ugh

Libraries, schools, hospitals and other public places block access to certain ports for apps like App Inventor as a security issue.  If you attempt to use App Inventor for live developments in these environments there are a few potential ways to develop.

I think you can:

1) Use the emulator http://appinventor.mit.edu/explore/ai2/setup-emulator.html  This may or may not work on your school net work that has the required ports blocked.

2) Use the USB option  http://appinventor.mit.edu/explore/ai2/setup-device-usb.html This may or may not work on your school net work that has the required ports blocked by school's IT security. If the method works, you will actually be able to use live development on your tablet.

3) and certain you can develop 'in the blind'.  Here is an solution to develop  (but not test live development), not perfect but it works:

*  Develop using the Designer small parts of a Project

*  Create an aia file

*  Build the Project   Build app (save apk to my computer)

*  Send the apk to a device by eMail attachment of the apk file

*  Click on the attachment when received on the device to install the app. Then test the app and cross your fingers.

This is called 'programming in the blind' and it has its pitfalls but does work.
