Android Design: Intentservice causing application not responding

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.

Solved: Android socket is not getting connected to the server

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);
}

Currently there is no option to save remote media stream on android.You will have to implement a media server which would save media stream and pass stream between two devices. Kurento is an open source media server which I know provides the functionality but I haven't used it

Establish DataChannel between Android app and Chrome client

So I'm badly stuck in creating a datachannel between android app client and Web App client running on Chrome.
Following is my complete code for which Audio and Video is streaming fine. But When I try to send the message using DataChannel it returns False and State as CONNECTING. I'm trying to resolve since 1 week but couldn't make it run.
EDIT: Issue resolved. Here is the final Working Code. Android Do not support RTPDataChannel anymore

Edit: There is no issue at web client as similar app in ios is working fine in similar scenario.

Stream from Android app to browser client app via socket.io-client and libjingle

So I'm trying to connect Android to Browser via webRTC via socket.io and libjingle and server is running on Node.js .
Issue I'm facing is weired.
When 1 client is at Android(native app) and other is at Ipad(native app), Everything works fine.
When 1 client is at iPad(Native app) and other is WebApp, Everyting works fine.
But When 1 Client is at Android(native app) and other is WebPage, everyting works fine except the audio and video is not streaming to that end.
Following are the two major classes i've used for the purpose:
