Flags

Flags of various sorts. Many instruct the Android system how to launch an activity (for example, which task the activity should belong to) and how to treat it after it's launched (for example, whether it belongs in the list of recent activities). All these flags are defined in the Intent class.

The Android system and the applications that come with the platform employ Intent objects both to send out system-originated broadcasts and to activate system-defined components. To see how to structure an intent to activate a system component, consult the list of intents in the reference.
