How to lock screen orientation on OSNow Android ?

Hi,

I'm modifying the OSNow app for Android and want an app to have only "portrait" mode.
I've tried <preference name="orientation" value="portrait" /> in res/xml/config.xml and added ..android:screenOrientation="portrait"... to AndroidManifest.xml to all my activities but none of that has an effect - app still rotating when device orientation is changed. Any other option to try or there is special option somewhere else?
Thank you.

Nick

Hi César,

Thank you very much for your reply. I've changed all SCREEN_ORIENTATION... to SCREEN_ORIENTATION_SENSOR_PORTRAIT in WebApplicationActivity.java and it worked :) 

Best regards,
Nick
