Switching Between Tasks

This scenario shows how the user can switch between two tasks. In this example, the user writes a text message, attaches a picture, but before they are done they glance at their calendar. They then return to where they left off, attaching the picture and sending the message.

1. Start first task. You want to send a text message and attach a photo. You would choose:

Home > Messaging > New message > MENU > Attach > Pictures. This last step launches the picture gallery for picking a photo. Notice that picture gallery is an activity in a separate application.

Home > Messaging > New message > MENU > Attach > Pictures. This last step launches the picture gallery for picking a photo. Notice that picture gallery is an activity in a separate application.

Messaging Task

At this point, before you have picked a picture, you decide to stop and glance at your calendar, which is a separate task. Because the current activity has no button to go directly to the Calendar, you need to start from Home.

2. Start second task. You choose Home > Calendar to look at a calendar event. Calendar launches from Home as a new task because the application launcher creates a new task for each application it launches.

3. Switch to first task and complete it. When done looking at the Calendar, you can return to attaching the picture by starting the root activity again for that task: choose Home > Messaging, which takes you not to Messaging, but directly to the Picture gallery, where you left off. You can then pick a photo, which is added to the message, you send the message and you're done with the first task.
