added in API level 21

                Bundle options)

Start an activity in this task. Brings the task to the foreground. If this task is not currently active (that is, its id < 0), then a new activity for the given Intent will be launched as the root of the task and the task brought to the foreground. Otherwise, if this task is currently active and the Intent does not specify an activity to launch in a new task, then a new activity for the given Intent will be launched on top of the task and the task brought to the foreground. If this task is currently active and the Intent specifies Intent.FLAG_ACTIVITY_NEW_TASK or would otherwise be launched in to a new task, then the activity not launched but this task be brought to the foreground and a new intent delivered to the top activity if appropriate.

In other words, you generally want to use an Intent here that does not specify Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_NEW_DOCUMENT, and let the system do the right thing.

Parameters
context Context

intent Intent: The Intent describing the new activity to be launched on the task.

options Bundle: Optional launch options.
