[android-developers] Avoiding the dreaded ANR & background work

I have been experimenting with an easy way to execute "synch" type bursts without all the hassle of Services, Loaders, Threads, etc.  I have come up with a technique that works great, but I'd like to get a consensus regarding the pattern.  I am performing sendBroadcast("synch.my.app") from the activity needing an update.  This same activity is registering a broadcast receiver registerReceiver(payload, new IntentFilter("here.is.the.json")) which is being notified from the "synch.my.app" receiver.  In other words, my broadcastreceiver is calling me back once it has the data.  Is this crazy?  I'm simply poking my json payload into the intent before sending broadcast back to activity.
