kieSession object is null when trying to call rule jar from an andriod application

[Ranjan Das]

Hi Everyone ,

I have created a rule  jar from workbench , wrapped it in a maven java project ( this project has the code to create the kie session and execute the rules.)

Then i have create a mobile app and trying to execute the rules from my app, I am able to call the wrapper jar but getting null pointer exception in the 2nd line  (basically kiecontainer object is null)

KieContainer con = ks.getKieClasspathContainer();

kSession = contnrExceptionLD.newKieSession();

To build my mobile app i had to exclude the below else the project was not getting build:

exclude MEA-INF/kie.cong

exclude module: 'xpp3_min' 

if i dont exclude ,getting build error of "More than one file was found with OS independent path META/kie.conf"

Note : I am able to call the wrapper rule jar from any java project (rules are getting fired) but not from android app.Need help on the same

Thanks In Advance
