1. For an app to print it creates a PrintDocumentAdapter implementation
which is passed to the print dialog activity. If the activity that
created the adapter is destroyed then the adapter, which may rely on
the activity state, may be in an invalid state. For example, an app
creates an adapter and calls print resuting in the app activity and
the print dialog activity being stacked. Now the user rotates the
device which triggers the recreating of the activity stack (assume the
app does not handle rotation). The recreated print dialog activity
receives the intent that originally created it with containing the
adapter that was constructed in the context of the old, now destroyed,
app activity instance.
To handle this we are limiting an app to be able to print only from
and activity and when this activity is destroyed we mark the adapter
as invalid which will result in hiding the print dialog activity. Note
that if the app process is killed we already handle this in the print
dialog activiy by registering a death recipient on the adapter binder.
2. In the PrintManager.PrintDocumentAdapterDelegate some of the state is
accessed only on the main thread and some from miltiple threads. The
code was trying to avoid locking for state that is not accessed by
multiple threads but this is error prone and the benefit does not
justify the complexity and added fragility. Now grabbing a lock all
the time.
3. The PrintJobConfigActivity waits for it to bind to the print spooler
service before instantiating its print controller and editor. However,
these can be accessed by invoking some of the activity cycle callbacks.
This change is adding null checks for the case where the activity
callbacks are called before the binding to the spooler is completed.

When the app spends more than half a second responding to a touch
event, the input dispatch eventually decides to stop sending it
events until it catches up. (This is when the ANR clock starts.)
However, due to a bug in the timing logic, if the app eventually
does respond again we would resume delivery but only send one
event at a time until the queue was completely drained again.
This meant it could take a long time to catch up and process all
events.
The problem is that we were comparing the current time with the
waiting event time. So when events became older than half a second,
we would simply stop streaming and end up serialized.
This change fixes the timing logic such that the streaming timeout
is based on the delivery time of the waiting event rather than
the event time itself. Now we only stop streaming when it has
been over half a second since the waiting event was delivered
so we resume streaming immediately as soon as some waiting
events are handled.
