Cause it doesn't.

I have a service running an Asynctask to do some work.

I bind to it from an activity and call a cancel method. The service,
in turn, calls AsyncTask.cancel(true);

AyncTask.cancel returns true. Nonetheless, the thread is still running
happily and still doing the things in doInBackGround, sending
notifications along the way.

There is no sign that it attempted to kill the thread.

I am not using NDK calls or anything that I think should stop if from
taking down the thread.

What am I doing wrong? Or is this a known issue?

public final boolean cancel (boolean mayInterruptIfRunning)

Since: API Level 3
Attempts to cancel execution of this task. This attempt will fail if
the task has already completed, already been cancelled, or could not
be cancelled for some other reason. If successful, and this task has
not started when cancel is called, this task should never run. If the
task has already started, then the mayInterruptIfRunning parameter
determines whether the thread executing this task should be
interrupted in an attempt to stop the task.
Parameters
mayInterruptIfRunning   true if the thread executing this task should be
interrupted; otherwise, in-progress tasks are allowed to complete.
Returns
false if the task could not be cancelled, typically because it has
already completed normally; true otherwise
