Execute python script from my java android app

I have an app in mind that will run various python scrpits. But I have a problem running python scripts from my java code.

I tried to use QPython, but I will have to start new intent to run my python code. That's not a problem but I have to close QPython intent manually to receive console output back to my app. That's not go.

Also I looked at sl4a and its fork android scripting but I didn't find any examples of how can I do such a thing from my JAVA code. Thanks.
