The following exercise demonstrates the usage of implicit intents to trigger activities in your Android system.

intent.estdataandtype When this happens, they should be returned as the getClipData part of the result Androld. For example, from a component of your application you can trigger another component in the Android system, which manages photos, even if this component is not part of your application.
Registering for intents via intent filters Intents are used to signal to the Android system that a certain event has occurred. For example, consider a task consisting of four activities: Note that the packages in this list do not receive this broadcast.
MakeText this, errorMessage, ToastLength. Allow to start the learning activity Allow to start this activity from the UserOverviewActivity via the Practice text view. For example, when used on a contacts entry it will view the entry; when used on a mailto: If a replacement extra has the same key as an extra already present in the intent it will overwrite the extra from the intent.

When a profile goes into quiet mode, all apps in the profile are killed and the profile user is stopped. This should only be used to determine when intent.setdstaandtype wallpaper has changed to show the new wallpaper to the user.
