I figured it out. If you have the Activity register the BroadcastReceiver programatically (ie, not in the manifest file), the Activity can have a reference to the BroadcastReceiver. Then you can give the Activity a listener interface and register it with the BroadcastReceiver. So instead of having the BroadcastReceiver fire an Intent, it just calls the callback on the Activity. You may have to set up a Runnable and call runOnUiThread() on the Activity, but it works just fine.
