AS3 Why isn't RTMFP android to android connecting? - actionscript-3

Question

I'm making a connection with netconnection in AS3 Flash CS6. It works fine when I test the swf from my PC to the app on my Android. But when I install the app on 2 android devices they don't connect. Why is that? If I test with my PC and the two android devices it works too. How can I make it work with only the two android devices?
Here's the code I'm using:
var nc:NetConnection;
var group:NetGroup;
nc = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS, netStatus);
nc.connect("rtmfp:");
function netStatus(event:NetStatusEvent):void{
switch(event.info.code){
// The connection attempt succeeded
case "NetConnection.Connect.Success":
setupGroup();
break;
// The NetGroup is successfully constructed and authorized to function.
case "NetGroup.Connect.Success":
break;
// A new group posting is received
case "NetGroup.Posting.Notify":
trace("notify");
break;
case "NetGroup.SendTo.Notify":
trace("notify received");
break;
// user joins?
case "NetGroup.Neighbor.Connect":
break;
}
}
// Create a group
function setupGroup():void {
// Create a new Group Specifier object
var groupspec:GroupSpecifier = new GroupSpecifier("test");
// Enable posting
groupspec.postingEnabled = true;
//groupspec.routingEnabled=true;
// Specifies whether information about group membership can be exchanged on IP multicast sockets
groupspec.ipMulticastMemberUpdatesEnabled = true;
// Causes the associated NetStream or NetGroup to join the specified IP multicast group and listen to the specified UDP port.
groupspec.addIPMulticastAddress("225.225.0.1:30000");
// Constructs a NetGroup on the specified NetConnection object and joins it to the group specified by groupspec.
group = new NetGroup(nc,groupspec.groupspecWithAuthorizations());
// Set the NET_STATUS event listener
group.addEventListener(NetStatusEvent.NET_STATUS,netStatus);
}

I suggest adding a default case statement to your switch. It may or may not shed some light on what is happening:
switch (event.info.code)
{
case "NetConnection.Connect.Success":
// etc... Not showing orig code
break;
// rest of the case statements here
// then lastly add this:
default:
trace(event.info.code);
}
