 - **Proper screen-to-screen communication.** Android's API does not provide a proper way of sending complex data (e.g., some Java Object) from one activity to another activity. With fragments, however, you can use the instance of an activity as a channel of communication between its child fragments.
 
-- **Many Android classes expect fragments.** The [API for tabs on the ActionBar](http://developer.android.com/reference/android/app/ActionBar.html#newTab()) expects the tab contents to be fragments. Also, if using Google Maps API v2, the [recommended solution](https://developers.google.com/maps/documentation/android/) is [MapFragment](http://developer.android.com/reference/com/google/android/gms/maps/MapFragment.html), even though [MapView](http://developer.android.com/reference/com/google/android/gms/maps/MapView.html) exists.

-- **Easy to implement swiping transitions between screens.** If a UI screen is a fragment in your application, you can use `FragmentPagerAdapter` to contain a collection of fragments and implement smooth and interactive transitioning between them. For instance, horizontal swiping of screens.
-
-- **Intelligent behavior for "back".** The [FragmentManager](http://developer.android.com/reference/android/app/FragmentManager.html) allows you to perform transactions to change the fragments inside an activity. Hence, the FragmentManager manages the "state" of fragments. The back button/action will be handled by the FragmentManager to go back to the previous "fragments state". This is more advanced than the [activity stack](http://developer.android.com/guide/components/tasks-and-back-stack.html).
-
 - **Fragments are generic enough to not be UI-only.** You can have a [fragment without a UI](http://developer.android.com/guide/components/fragments.html#AddingWithoutUI) that works as background workers for the activity. You can take that idea further to create a [fragment to contain the logic for changing fragments](http://stackoverflow.com/questions/12363790/how-many-activities-vs-fragments/12528434#12528434), instead of having that logic in the activity.
 
 - **Even the ActionBar can be managed from within fragments.** You can choose to have one Fragment without a UI with the sole purpose of managing the ActionBar, or you can choose to have each currently visible Fragment add its own action items to the parent Activity's ActionBar.
