Hi TIMAI2
yes SM-T05 (Galaxy Tab A7) and android 12
On a chinese tablet KEP android 10 it works! Any suggestions ?
Temporarily use the companion app on those devices which work or test using the apk file while the MIT App Inventor team hopefully will look into this issue soon

I have the same problem (getting the out-of-bounds message when trying to run latest version of companion). Running Android 13 on Samsung S20. Everything was working fine yesterday morning with older version of companion (2.70?). Accidently deleted it off my phone. Reloaded companion from Google Play. Gotten the error ever since. Any way to get access to older versions of companion to try?
I don't get this error, but I can't connect to the companion because the extension jar file isn't being sent, and neither are resources like images. Oddly enough, everything works fine on my locally compiled server.
The problem seems to be in Companion itself. When I use Companion compiled locally, this error does not occur.
Once my locally compiled Companion has downloaded the resources and jar files to ASD, then connecting to Companion installed from GooglePlay works fine. So the problem is in downloading resources from the server to ASD.
Maybe the new Companion after the ListView hot fix will fix the situation.

We don't apply any patches in production that would affect the extension loading path. I'm going to run some tests and see if I can reproduce it.

I think this error may simply be due to lack of resources in the ASD Companion.
The first attempt to connect after installing Companion ended with an error. Another attempt and the connection was problem-free. Something is not stable.
In my case there were 3 error symptoms:
- error: java.lang.StringIndexOutOfBoundsException
- error: Unable to load file...../classes.jar
- and a problem that after updating the extension with new methods, these methods were not available in companion, i.e. the classes.jar file did not update in asd but the connection to companion was successful.

What happens if you try a project without extensions ? (as previously suggested)
What happens if you try a project with no extensions but also with some media assets ?
Without extensions it work in all my tablets and android versions

Thank you, we are getting somewhere.
Should we create a new topic, e.g. Companion Extension Issues: nb199 and 2.73u and move all the topics there ?
