How do I launch a QPython Script from MIT App Inventor Activity Starter and exit cleanly?

Question

I have made a simple training app with MIT App Inventor 2. The app logs to a logfile, and I've made a small QPython script to analyze the log and display stats.

I'd like to use the Activity Starter to launch my Python script, but I haven't been able to figure out the correct set of Action, ActivityClass, ActivityPackage and Extra[x] to make it work. I've run adb on my Android phone to find the correct strings but I get a "601 No corresponding activity was found" when I try.

Here's the adb output grepped for "qpyplus" while running the script:

I've read the docs and tried to decipher the logs and populate the tags. I've also found an old answer from 2010 to the same sort of question, but it seems that QPython has moved on since then because the recipe doesn't correspond to my logcat (and also doesn't work). Please see screenshot of both options (I'm a rookie here so I'm not allowed to embed images).

screenshot of two options that don't work Does anybody know how I should format the Activity Starter for this script to run?

Update!
Taifun has put me on the right track, I think. I've followed his advice and re-compiled the .apk with new permissions and installed it so that it will be allowed to run a shell script. My problem now is that QPython seems to completely ignore my asking it to run a script on startup. The terminal opens okay, but my script doesn't run. If I run the command manually, it runs just fine.

Any thoughts?

My new config that almost works.

action="com.hipipal.qpyplus.action.MPyApi"
classname="com.hipipal.qpyplus.MPyApi"
packagename="com.hipipal.qpyplus"
extras={"app" : "appid", "act" : "onPyApi", "flag" : "onQPyExec", "param" : "", "pycode" : "print 'selam'\nprint 'naber'"}

This is working fine :)
