[android help] Unable to instantiate fragment make sure class name exists, is public, and has an empty constructor that is public

Unable to instantiate fragment make sure class name exists, is public, and has an empty constructor that is public

I am using the Fragment and When I change the orientation of the device. If initially its portrait and when i change it to landscape then my application crash. I added the logcat here. I have gone through many links but could not find the right answer.

Please help me to solve this issue.

Thanks
