What that code does, is similar to using the App start block with...
Package: com.hipipal.qpyplus
Activity class: com.hipipal.qpyplus.MPyApi
Action: com.hipipal.qpyplus.action.MPyApi
Extras: { "app":"myappid", "act":"onPyApi", "flag":"onQPyExec", "param":"", "pycode":"<code goes here>" }
You should likely use the File read block to read the Python code (replacing the "<code goes here>" literal), otherwise you'll have to escape the code all the ", \n, {, etc.
