Android Fragment Example

A Fragment is a piece of an application's user interface or

 behavior that can be placed in an Activity.

 Interaction with fragments is done through

 FragmentManager, which can be obtained via

 Activity.getFragmentManager() and Fragment.getFragmentManager().


The Fragment class can be used many ways to achieve a wide variety 

of results. In its core, it represents a particular operation or i-

nterface that is running within a larger Activity. A Fragment is 

closely tied to the Activity it is in, and can not be used apart

from one.Though Fragment defines  its own lifecycle, that 

lifecycle  is dependent on its activity: if the activity is 

stopped, no fragments inside of it can be started; 

when the activity is destroyed, all fragments will be destroyed.
