I have designed a code which leads to application not responding.
I have used okhttp3.WebSocket for continuous input stream of data on which i am deciding to start an IntentService which will be fetching data from server.
I have an IntentService; in onHandleIntent i am giving an service call for fetching data from the server(roughly 3 calls).
For Service call i am using AsyncTask of android inside which my WebConnectionManger class runs on different thread.
Inside websocket i am getting details of a particular record for which i am going to fetch the details from the service call.
For 5-6 such records my application runs fine, but if records get 80-100 my application do not respond at all and i get ANR.
I am using simple plain TCP request for this.
can any on tells me what is the actual issue and how i can get rid of it?
any help is appreciated.
i am pasting the code of WebSocket, AsyncTask(rest two have same implementation), WebConnectionManger class and IntentService class.

You may want to check what is blocking the main thread for more than 6 seconds.
Usually ANR happens when main thread is blocked for some time. 6-10 seconds.
I'm trying Smack 4.2 on Android and I have a problem with the IncomingListener.
I created a class MyXMPP totaly dedicated to XMPP work.
( I just have one android activity. )
In this activity, in OnCreate(), I connected to XMPP server using my class MyXMPP and I retrieved my ChatManager in my a final value to place on an IncomingChatMessageListener().
Everything works well in the first try. But when I pause my activity and relaunch it, it's like the older listener remains. So at this moment, I receive messages in double.
If I pause again my application, it's like I have 3 listeners and so on.
I precise I have no problem whith connection to my server.
Here my code :
Android activity :
public class TestMessagingActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test_messaging);
MyXMPPP.getInstance().init("test", "test");
MyXMPPP.getInstance().connect();
final ChatManager chatManager = MyXMPPP.getInstance().getChatManager();
chatManager.addIncomingListener(new IncomingChatMessageListener() {
#Override
public void newIncomingMessage(EntityBareJid from, Message message, Chat chat) {
final AsyncTask<Message, Void, Void> mReceiveMessage = new AsyncTask<Message, Void, Void>() {
#Override
protected Void doInBackground(Message... params) {
ChatMessage chatMessage = new ChatMessage(params[0].getBody(), false);
Log.v("TAG", "index=message arrived");
Log.v("TAG", params[0].getBody());
return null;
}
#Override
protected void onPostExecute(Void res) {
}
};
mReceiveMessage.execute(message);
}
});
}
}
MyXMPP class :
public class MyXMPPP {
private static final String DOMAIN = "test.com";
private AbstractXMPPConnection connection;
private XMPPConnectionListener connectionListener = new XMPPConnectionListener();
private ChatManager chatManager;
private Presence presence;
boolean isConnected=false;
boolean chatManagerCreated=false;
private static MyXMPPP instance =null;
public synchronized static MyXMPPP getInstance() {
if(instance==null){

}

configBuilder.setUsernameAndPassword(user, password);
configBuilder.setSecurityMode(ConnectionConfiguration.SecurityMode.required);
configBuilder.setKeystoreType(null);
try {
configBuilder.setXmppDomain(DOMAIN);
} catch (XmppStringprepException e) {
e.printStackTrace();
}
connection = new XMPPTCPConnection(configBuilder.build());
connection.addConnectionListener(connectionListener);
}
public void connect() {
if (isConnected == false) {
AsyncTask<Void, Void, Boolean> connectionThread = new AsyncTask<Void, Void, Boolean>() {
#Override
protected Boolean doInBackground(Void... params) {
try {
connection.connect();
connection.login();
} catch (SmackException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (XMPPException e) {

} catch (InterruptedException e) {

}
return null;
}
};

}
}

return connection;
}
public void createChatManager()
{
if(chatManagerCreated==false)
{
chatManager=ChatManager.getInstanceFor(connection);
chatManagerCreated=true;
Log.v("TAG", "index=chat manager created");
}
}
public ChatManager getChatManager()
{
return chatManager;
}
public void sendMessage(String message, EntityBareJid jid)
{
if(chatManagerCreated==true)
{
Chat chat = chatManager.chatWith(jid);
try {
chat.send(message);
} catch (SmackException.NotConnectedException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
public boolean getIsConnected(){
return isConnected;
}
public class XMPPConnectionListener implements ConnectionListener{
#Override
public void connected(XMPPConnection connection) {
}
#Override
public void authenticated(XMPPConnection connection, boolean resumed) {
isConnected=true;
createChatManager();
presence = new Presence(Presence.Type.available, "Online", 24, Presence.Mode.available);
try {
connection.sendStanza(presence);
} catch (SmackException.NotConnectedException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
#Override
public void connectionClosed() {
isConnected=false;
}
#Override
public void connectionClosedOnError(Exception e) {
isConnected=false;
}
#Override
public void reconnectionSuccessful() {
}
#Override
public void reconnectingIn(int seconds) {
}
#Override
public void reconnectionFailed(Exception e) {
}
}
}
Is this problem normal ?
When I put the listener to on the chatManager in the XMPP class, I don't have this problem. But I would like to do work in my activity / in my view, so having the listener here seems to be better.
I need some advice.
Thank you.
Nico.
Here I have a query related to connection between android socket and server. I'm following https://socket.io/blog/native-socket-io-and-android/ and found that it is working fine, so I replaced my local server URL with the URL in the tutorial. But here I'm always getting a connection failed or disconnection error. Here is my application class for further clarification.
public class ChatApplication extends Application {
private Socket mSocket;
{
try {
IO.Options options = new IO.Options();
options.forceNew = true;
options.reconnection = true;
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put("uid", 1);
jsonObject.put("usid", 6847);
options.query = jsonObject.toString();
} catch (JSONException e) {
e.printStackTrace();
}
Log.e("JSON", jsonObject.toString());
Log.e("OPTIONS", options.toString());
mSocket = IO.socket(Constants.CHAT_SERVER_URL, options);
} catch (URISyntaxException e) {
throw new RuntimeException(e);
}
}
public Socket getSocket() {
return mSocket;
}
}

I'm using CHAT_SERVER_URL = "http://192.168.1.14:3000/" to make connection with server but it's not working for me. It works fine when we try to make a web connection through emulator or computer system. Can anyone please give me an idea if I'm doing anything wrong.
Thanks.
After debugging at the server end too, I got to know how to hit my server to make a connection and I got that we don't require IO.Options and Options.query in every case and now it is working fine completely. So for more clarification I'm posting an answer here:
//connect to server
public void startRunning() {
try {
if (baseUrl != null) {
socket = IO.socket("http://" + baseUrl + ":3000?uid=" + userId + "&usid=" + userSessionId);
}
} catch (URISyntaxException e) {
e.printStackTrace();
}
if (socket == null) return;
socket
.on(Socket.EVENT_CONNECT, CONNECTED)
.on(Socket.EVENT_DISCONNECT, DISCONNECTED)
.on("chat-message", CHAT_MESSAGE)
.on("chats-active", CHATS_ACTIVE)
.on("chat-logout", LOGOUT)
.on("messages-read", MESSAGE_READ)
.on("chat-login", CHAT_LOGIN);
socket.connect();
}
I am facing the problem to create a new user on ejabberd server but sign in is working fine. i used the github repository (https://github.com/dilicode/LetsChat) for register the new user and chat between two and more users. I search on intenet, i found some way to register those are:
1.add
%% In-band registration
{access, register, [{allow, all}]}.
in access rules in ejabberd server and
2. also add
{mod_register, [
{access_from, register},
...
] ...
it in access rules of ejabberd server.

This is the code through which i am calling connection instance
connection=((Authenticate)getApplication()).getConnection();
Listener function
public void listenChat(String name){
ChatManager manager = ChatManager.getInstanceFor(connection);
manager.addChatListener(new ChatManagerListener() {
#Override
public void chatCreated(final Chat chat, boolean createdLocally) {
System.out.println("Created chat");
chat.addMessageListener(new ChatMessageListener() {
#Override
public void processMessage(final Chat chat, final org.jivesoftware.smack.packet.Message message) {
//This is called twice
}
}
});
}
});
}
I am a beginner in android and as well in xmpp.Please tell me where i am wrong how can i resolve it
You have to fix createdLocally usage in chatCreated method.
Just add the listener if is not createdLocally like this:
public void chatCreated(Chat chat, boolean createdLocally)
{
if (!createdLocally)
{
chat.addMessageListener(new ChatMessageListener()...);
}
}
