Does your receiver handle the JSON update (i.e. it goes out to the server,
retrieves the updated json from the server and notifies the registered
activities)?
If so, this is not correct. BroadcastReceivers should never ever do long
running tasks.
Instead, your BroadcastReceiver should receive the "synch.my.app" request.
It then would start a Service (preferrably a wakefull IntentService) that
does the actual work (since IntentServices can run for longer times). The
IntentService then sends a "here.is.the.json" broadcast back, when it's
done, to the registered activities.
BTW: Instead of sending back "here.is.the.json" broadcasts, your calling
Activity could add a ResultReceiver to the Intent. The BroadcastReceiver
will send the Intent including this ResultReceiver to the IntentService.
And when the IntentService is done, the IntentService could just call
'send(resultCode, resultData)' to update the calling Activity of the final
result.
