well passing info between fragments on same activity, easiest method calling function in acitivity 1st , passing info second.

kind of on first fragment.

((activityclass) getactivity()).functonwithvaraiblestopasstosecond(variables); 

in activity class

pubic void functonwithvaraiblestopasstosecond(variables) {      secondfragment.funcitontoacceptvariables(varaibles); }
