  Same lifecycle methods with the Activity lifecycle methods apply

  extends DialogFragment
Displays a floating dialog. Using this class to create a dialog is a good alternative to using the dialog helper methods in the Activity class, because you can incorporate a fragment dialog into the back stack of fragments managed by the activity, allowing the user to return to a dismissed fragment.

  extends ListFragment
Displays a list of items that are managed by an adapter (such as a SimpleCursorAdapter), similar to ListActivity. It provides several methods for managing a list view, such as the onListItemClick() callback to handle click events.

// Set the user interface layout for this Activity (activity_main.xml)
//Usually in the onCreate method
setContentView(R.layout.activity_main);

//R.java file have all the resources IDs provided to resources(drawables, layouts, styles etc)
//Example
R.id.edit_message //id of a layout view in the xml
