SingleTask

The other three modes permit multiple activities to belong to the task. A "singleTask" activity will always be the root activity of the task, but it can start other activities that will be assigned to its task. Instances of "standard" and "singleTop" activities can appear anywhere in a stack.

• Whether a new instance of the class will be launched to handle a new intent. For the default "standard" mode, a new instance is created to respond to every new intent. Each instance handles just one intent. For the "singleTop" mode, an existing instance of the class is re-used to handle a new intent if it resides at the top of the activity stack of the target task. If it does not reside at the top, it is not re-used. Instead, a new instance is created for the new intent and pushed on the stack.
