I'd like to use RabbitMQ client from an android App.
From the server side, i use SpringBoot with spring AMQP. RabbitMQ (rabbitmq_server-3.4.3) is installed correctly and an integration test valid the server behaviour.
The difficult part is when i try to create a connection from RabbitMQ connectionFactory inside my android project.
I get this exception :
failed to connect to localhost/127.0.0.1 (port 5672):
connect failed: ECONNREFUSED (Connection refused)
In android manifest, Internet permission is set :
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
Here is my code :
public class LoadingTask extends AsyncTask<String, Integer, Integer> {
private static String replyQueue = "REPLY_QUEUE";
public interface LoadingTaskListener {
void onResourceLoaded();
}
private final ProgressBar progressBar;
private final LoadingTaskListener loadingTaskListener;
private ConnectionFactory connectionFactory;
public LoadingTask(ProgressBar progressBar, LoadingTaskListener loadingTaskListener) {
this.progressBar = progressBar;
this.loadingTaskListener = loadingTaskListener;
this.connectionFactory = new ConnectionFactory();
connectionFactory.setAutomaticRecoveryEnabled(true);
}
#Override
protected Integer doInBackground(String... params) {
try {
/*init rabbitMQ Context*/
Connection connection = connectionFactory.newConnection();
Channel channel = connection.createChannel();
channel.basicQos(1);
channel.queueDeclare(DATA_QUEUE.getName(), false, false, false, null);
AMQP.Queue.DeclareOk q = channel.queueDeclare();
channel.queueBind(q.getQueue(), "amq.fanout", "chat");
QueueingConsumer consumer = new QueueingConsumer(channel);
channel.basicConsume(replyQueue, true, consumer);
/* initiate RPC */
String corrId = java.util.UUID.randomUUID().toString();
AMQP.BasicProperties props = new AMQP.BasicProperties.Builder()
.correlationId(corrId)
.replyTo(replyQueue)
.build();
AmqpRequest request = new AmqpRequest(LIST_IMAGE);
Gson gson = new Gson();
String jsonRequest = gson.toJson(request);
channel.basicPublish(MAIN_EXCHANGE.getName(), DATA_QUEUE.getRoutingKey(), props, jsonRequest.getBytes());
String response;
while (true) {
QueueingConsumer.Delivery delivery = consumer.nextDelivery();
if (delivery.getProperties().getCorrelationId().equals(corrId)) {
response = new String(delivery.getBody());
break;
}
}
System.out.println(response);
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
// Dummy Data until i can't connect to rabbitMQ
return 1234;
}
}
Is it really possible to connect Android on RabbitMQ, or should i use a kind of http bridge ?
Could anyone provide me an exemple for both http bridge or RabbitMQ connection.
Thank you

I solved it. I was doing two mistakes
Appium Path was not correct.
Incorrect path was
builder.withAppiumJS(new File("C:\Users\Ritesh Mittal\AppData\Roaming\npm\node_modules\appium\lib\appium.js"));
corrected:
builder.withAppiumJS(new File("C:\Users\Ritesh Mittal\AppData\Roaming\npm\node_modules\appium"));
added arguments
builder.withArgument(() -> "--base-path", "/wd/");
I'm building a PJSUA2 (PJSIP 2.8) Android app and I have some issues: i.e. only on incoming call, call state remains in "PJSIP_INV_STATE_CONNECTING" and after 32 seconds the call drops.
I'm looking for the cause of the issue since several days, I googled a lot and all what I found is: in most situations this issue is related to NAT management or network issues related to NAT. In a few words: in most cases the called party does not receive the ACK after answering the call.
Finally I was able to log all SIP messages between my app and the SIP server and found that my app receives the ACK from the server, so I suppose it's not a network related issue.
I compiled PJSIP 2.8 with OpenSSL and SRTP support, but without video support (I don't need it at least at the moment). If it makes any difference, the app has a target version 28 and minimum SDK version 19.
I tried several apps on the market and they work fine enough with and without SRTP and with all signaling transports (UDP, TCP, TLS), WebRTC works fine too (tested with SipML5), so I would exclude a server misconfiguration. My app does the same (except SRTP with which I have some issues at the moment).
I tried with a SIP provider too (MessageNet) using UDP and the behaviour is always the same. I tried to use compact SIP messages and it behaves the same, with and without uri parameters, with and without STUN and or ICE and nothing changes. Mobile network and WiFi networks give the same results.
I tried to debug inside PJSIP library too, but without any success, then I tried to follow the code, to understand what I was doing wrong, but it doesn't seem to me there is something evidently wrong.
The following is the code (last version) which initializes PJSIP:

Finally, how I answer the code at the moment in a class which extends the PJSIP's Call class:
#Override

Log.d(TAG, "Answering call...");
CallOpParam prm = new CallOpParam(true);
prm.setStatusCode(pjsip_status_code.PJSIP_SC_OK);
prm.getOpt().setAudioCount(1);
prm.getOpt().setVideoCount(0);
try {
this.answer(prm);
} catch (Exception e) {
e.printStackTrace();
}
}
I also tried with new CallOpParam(); with just the status code and nothing else, but nothing changes.
One note: I created the IdUri as sip:username#127.0.0.1 because without the host the resulting contact was and I thought that the missing user part may be the cause of the issue or part of it.
The following is the trace of the app <-> my Asterisk server communication during call (linked because of content length exceed).
https://gist.github.com/ivano85/a212ddc9a808f3cd991234725c2bdb45
The ServerIp is an internet public IP, while the MyIp[5.XXX.XXX.XXX] is my phone's public IP.
As you can see from the log, my app sends a 100 Trying, then a 180 Ringing when the phone rings, then the user answers and the app sends a 200 OK. The server replies with a ACK message (I would say it's not a NAT issue, because PJSIP receives the ACK). I see the same from Asterisk.
After this I would expect the call goes from PJSIP_INV_STATE_CONNECTING to PJSIP_INV_STATE_CONFIRMED, but it does not happen, so PJSIP continues to send a 200 OK and receive the ACK every about 2 seconds, until the call times out after 32 seconds and PJSIP disconnects the call (sending a BYE).
I'm starting to think that PJSIP just ignores ACK messages and just has a wrong behaviour. Please help me to understand what is happening here. I would appreciate it so much!
Obviously let me know if you think that more details are needed.
I have an app connected with Azure backend. I created a login and some api calls 2 months ago. They worked fine until a few days ago and then it starts to fail "sometimes".

I followed THIS tutorial to set up a .NET Backend for my Android app to implement Signal R. I set up a SignalR Self-Hosted backend.
Here's my Backend Code in a Console Project:

string url = "http://localhost:8080";
using (WebApp.Start(url))
{
Console.WriteLine("Server running on {0}", url);
Console.ReadLine();
}
}

public void SendMessage(string name, string message)
{
MessageReceived(name, message);
}
}
public class CustomType
{
public string Name;
public int Id;
}
}
My Android Code:

Platform.loadPlatformComponent(new AndroidPlatformComponent());
// Change to the IP address and matching port of your SignalR server.
String host = "http://192.168.1.5:8080/";
HubConnection connection = new HubConnection( host );
HubProxy hub = connection.createHubProxy( "MessageHub" );
ClientTransport transport = new ServerSentEventsTransport(connection.getLogger());

isConnected failed: ECONNREFUSED (Connection refused)
Is my code correct and have I followed the guide properly? It's a very straight forward guide but this issue comes up. Can someone help out?
EDIT:
This is a very similar Question, in fact it describes the same issue. However it didn't do me any good. If you notice my android code, I've already made those changes proposed in that question. Still didn't rectify the issue.

I had similar issue a few days ago and this Github issue helped:
https://github.com/SignalR/java-client/issues/63
Basically what I did was modify the WebsocketTransport.java in the signalr-client-sdk project. Replace:
uri = new URI(url);
with
uri = new URI(url.replace("http://", "ws://"));
around line 86 in the source code.
I can now connect and send message and recieve raw data but cannot subscribe to events...
Hope this helps you get passed your problem.
In My Android application I get xmpp connection initially using server_nm and 5222 port on login and done single chat message send and receive,but at time of file transfer, How I configure connection with proxy_server and 7777 port which use for file transfer?
public class XmppManager {

If you still want to transfer files via smack directly, you basically have too options, as far as I understand the API.
1.
First you can use In Band transmission, that is enabled via
FileTransferNegotiator.IBB_ONLY = true;
This sends your file as base64 encoded message, the same way you are sending a normal message packet.
The second option is to use a streaming proxy. This one is way faster since it does not need to encode / decode the file to base64 but transmitts the data directly. Both devices connnect to the proxy server and share data on this.
To configure a streaming proxy you have to configure it on the server side and add the Providers to your client side connection (this should be done automatically on the latest asmack library).
I configured such a setup using the ejabberd service and mod_proxy65 Mod_proxy65
add to your /etc/ejabberd/ejabberd.yml, your ip adress and host should match the service you are using.
host: "proxy1.example.org"
name: "File Transfer Proxy"
ip: "200.150.100.1"
port: 7777
Then allow the firewall to communicate on this port, and you should be good to go.
However, I figured out, that the file transfer only is functional, if both clients are in the presence "available" if any of them is in another state, the sender receives "service- unavailabe" errors.
Don't rely on XMPP file transfer using aSmack/Smack as it is buly. Instead you can create a plugin which will upload files to the server and after successfully uploading the files send the absolute url of the file to the recipient so that he/she can download the file from there.
Hope this works !
