Launch controls
on stopped applications
Starting from Android 3.1, the system's package manager keeps
track of applications that are in a stopped state and provides a
means of controlling their launch from background processes and
other applications.
Note that an application's stopped state is not the same as an
Activity's stopped state. The system manages those two stopped
states separately.
The platform defines two new intent flags that let a sender
specify whether the Intent should be allowed to activate components
in stopped application.
When neither or both of these flags is defined in an intent, the
default behavior is to include filters of stopped applications in
the list of potential targets.
Note that the system adds to all broadcast
intents. It does this to prevent broadcasts from background
services from inadvertently or unnecessarily launching components
of stoppped applications. A background service or application can
override this behavior by adding the
Applications are in a stopped state when they are first
installed but are not yet launched and when they are manually
stopped by the user (in Manage Applications).
