1. adapter.notifyDataSetChanged is not working for all fragments adapter . 2. Issue in setOffscreenPageLimit.

**1.** adapter.notifyDataSetChanged() is not working for the active fragments which are viewing. Except the active fragments other fragments dataSet are changed. So there is problem in notifyDataSetChanged() .

**2.** We can even setOffScreenPageLimit to 1 because default is two.

// YOUR CODE
public void setOffscreenPageLimit(int limit) {
super.setOffscreenPageLimit(2);
}
