I am self learner of android programming. i am using android fragments with REST API's and WEB Services. every thing is working fine till now. i am facing a issue when user click on back press of HARDWARE. i am getting confused in it.. when i am using back-stack then the issue is it will take me back but the title or fragments activity not changed as i am doing dynamically.
second thing.. some times its take me in correct way but event data of that activity also not loading..
Please help me.. if any sample stuff provide me in this then it would be a great thing for me.
