i don't think related problem, starting activity twice in activity main

mctx.startactivity(i); ((activity)mctx).startactivityforresult(i, 2); 

the first time without expecting result, second 1 expecting it. normally, start activity once. , same 'issue' have twice in activity infyrouteplanner now, problem, have checked this thread? hope helps
