messaging

I am working on a sms blocker application, in which i am using broadcast receiver and abortBroadcast() method - as many ppl have suggested here - to prevent messages from reaching inbox and alerting the user. But in my case, when I send a sms using the emulator, the SMS message won't get blocked, and reaches the inbox, also I get an error : 06-29 09:19:05.854: E/BroadcastReceiver(868): BroadcastReceiver trying to return result during a non-ordered broadcast which doesn't terminate the app in the emulator, however the application gets terminated when I test it on my phone. And yes, I have set

I am building a distributed system that consists of potentially millions of clients which all need to keep an open (preferrably HTTP) connection to wait for a command from the server (which is running somewhere else). The load of messages / commmands will not be very high, maybe one message / sec / 1000 clients which means it would be 1000 msg/sec @ 1 million clients. => it's basically about the concurrent connections. The requirements are simple too. One way messaging (server->client), only 1 client per "channel". I am pretty open in terms of technology (xmpp / websockets / comet / ...). I am

I am looking to be able to move messages between queues (manually) in Rabbit. For example: first-queue has messages ['a','b','c','d','e','f'] second-queue has messages ['x','y'] I want to be able to move for example message 'a' to second-queue from first-queue. This can be a manual operation. Both queues are on the same broker, and I do not want to send them through any exchange. Is there anyway to do this? I have been playing with rabbitmqctl but can't seem to get it to work. I am open to any other tools that would allow me to accomplish this. Eventually I am hoping to have some sort of

I have some problem with signalR, I can not send message to specific User From Hub. I want to do like this: public void Send(string userToId, string userForId, string message) { IHubContext context = GlobalHost.ConnectionManager.GetHubContext<ChatHubs>(); //userForId - it is Session["UserId"] context.Clients.User(userForId).updateMessages(message); } I have already read this topic: http://www.asp.net/signalr/overview/guide-to-the-api/mapping-users-to-connections , but It's not clear for me, because I have not this var name = Context.User.Identity.Name; I have User information in Session

I Understand that this question duplicates question at using rabbitmq to send a message not string but struct if to do this using the first way first way I have the following trace: java.io.EOFException at java.io.ObjectInputStream$PeekInputStream.readFully(ObjectInputStream.java:2304) at java.io.ObjectInputStream$BlockDataInputStream.readShort(ObjectInputStream.java:2773) at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:798) at java.io.ObjectInputStream.<init>(ObjectInputStream.java:298) at com.mdnaRabbit.worker.data.Data.fromBytes(Data.java:78) at com.mdnaRabbit.worker

I am conceptualizing an Android app that sends data from one device to another (like a picture message), but because I do not have a server, I am looking into other ways of messaging. Google Cloud Messaging (GCM) seems like a good choice, since its made for Android, and is free to use, but it still requires a server to use. Is there a way around this requirement- such as running the GCM server on the app itself? Or is there a better approach to serverless messaging on Android? I think that will be hard to do what you want effectively without a server but you can check out Parse's SDK. It is
