. In either case, when the
activity is re-launched while at the top of the activity stack instead
of a new instance of the activity being started, onNewIntent() will be
called on the existing instance with the Intent that was used to
re-launch it.
An activity will always be paused before receiving a new intent, so
you can count on Activity.onResume()
being called after this method.
Note that Activity.getIntent()
still returns the original Intent. You
can use Activity.setIntent(android.content.Intent)
to update it to this new Intent.

When activity B is launched in front of activity A, this callback will
be invoked on A. B will not be created until A's Activity.onPause()
returns,
so be sure to not do anything lengthy here.
This callback is mostly used for saving any persistent state the activity is editing, to present a "edit in place" model to the user and making sure nothing is lost if there are not enough resources to start the new activity without first killing this one. This is also a good place to do things like stop animations and other things that consume a noticeable amount of CPU in order to make the switch to the next activity as fast as possible, or to close resources that are exclusive access such as the camera.
In situations where the system needs more memory it may kill paused
processes to reclaim resources. Because of this, you should be sure
that all of your state is saved by the time you return from
this function. In general Activity.onSaveInstanceState(android.os.Bundle)
is used to save
per-instance state in the activity and this method is used to store
global persistent data (in content providers, files, etc.)
After receiving this call you will usually receive a following call
to Activity.onStop()
(after the next activity has been resumed and
displayed), however in some cases there will be a direct call back to
Activity.onResume()
without going through the stopped state.
Derived classes must call through to the super class's implementation of this method. If they do not, an exception will be thrown.

any configuration change occurs that is not selected to be reported

configuration).
At the time that this function has been called, your Resources object will have been updated to return resource values matching the new configuration.

on it, or because the system is temporarily destroying
this instance of the activity to save space. You can distinguish
between these two scenarios with the Activity.isFinishing()
method.
Note: do not count on this method being called as a place for
saving data! For example, if an activity is editing data in a content
provider, those edits should be committed in either Activity.onPause()
or
Activity.onSaveInstanceState(android.os.Bundle)
, not here. This method is usually implemented to
free resources like threads that are associated with an activity, so
that a destroyed activity does not leave such things around while the
rest of its application is still running. There are situations where
the system will simply kill the activity's hosting process without
calling this method (or any others) in it, so it should not be used to
do things that are intended to remain around after the process goes
away.
Derived classes must call through to the super class's implementation of this method. If they do not, an exception will be thrown.

Activity
If the focused view didn't want this event, this method is called.
The default implementation takes care of KeyEvent.KEYCODE_BACK
by calling Activity.onBackPressed()
, though the behavior varies based
on the application compatibility mode: for
Build.VERSION_CODES.ECLAIR
or later applications,
it will set up the dispatch to call Activity.onKeyUp(int, android.view.KeyEvent)
where the action
will be performed; for earlier applications, it will perform the
action immediately in on-down, as those versions of the platform
behaved.
Other additional default key handling may be performed
if configured with Activity.setDefaultKeyMode(int)
.

activities manage status bar notifications intelligently; specifically,
for helping activities determine the proper time to cancel a notfication.
All calls to your activity's Activity.onUserLeaveHint()
callback will
be accompanied by calls to Activity.onUserInteraction()
. This
ensures that your activity will be told of relevant user activity such
as pulling down the notification pane and touching an item there.
Note that this callback will be invoked for the touch down action that begins a touch gesture, but may not be invoked for the touch-moved and touch-up actions that follow.
