		* responsive to the broadcast, but does allow
		* the implementation to move work related to it over to another thread
		* to avoid glitching the main UI thread due to disk IO.
		*
		* <p>As a general rule, broadcast receivers are allowed to run for up to 10 seconds
		* before they system will consider them non-responsive and ANR the app. Since these usually
		* execute on the app's main thread, they are already bound by the ~5 second time limit
		* of various operations that can happen there (not to mention just avoiding UI jank), so
		* the receive limit is generally not of concern. However, once you use {@goAsync}, though
		* able to be off the main thread, the broadcast execution limit still applies, and that
		* includes the time spent between calling this method and ultimately
		* {@link PendingResult#finish() PendingResult.finish()}.</p>
		*
		* <p>If you are taking advantage of this method to have more time to execute, it is useful
		* to know that the available time can be longer in certain situations. In particular, if
		* the broadcast you are receiving is not a foreground broadcast (that is, the sender has not
		* used {@link Intent#FLAG_RECEIVER_FOREGROUND}), then more time is allowed for the receivers
		* to run, allowing them to execute for 30 seconds or even a bit more. This is something that
		* receivers should rarely take advantage of (long work should be punted to another system
		* facility such as {@link android.app.job.JobScheduler}, {@link android.app.Service}, or
		* see especially {@link android.support.v4.app.JobIntentService}), but can be useful in
		* certain rare cases where it is necessary to do some work as soon as the broadcast is
		* delivered. Keep in mind that the work you do here will block further broadcasts until
		* it completes, so taking advantage of this at all excessively can be counter-productive
		* and cause later events to be received more slowly.</p>
		*
		* @return Returns a {@link PendingResult} representing the result of
		* the active broadcast. The BroadcastRecord itself is no longer active;
		* all data and other interaction must go through {@link PendingResult}
