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.

Good day everyone, I would like to ask, hat is the cause of that ANR?. In my project I have service which is binded in a activity. Now when I exit in that activity the app is hang for a moment. My thought is that the service is still running though I unbind it in onStop() of the activity.
Here is my service class

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);
}
} catch (URISyntaxException e) {
e.printStackTrace();
}
if (socket == null) return;

How to wait for an activity to finish in asynctask

Flickr Sign out in Android programmatically

I am getting some issue when image is uploaded to flickr,oath token as well as user credentials get stored in the web browser cache.As a result am not being able to sign out from it.So when I go to flickr to upload my image again,it automatically uploads it rather than opening the login page.Now when I clear all the default browser cookies,then it ask for the login page.Is there any other way to sign out it automatically when I am redirected back to my application.Any kind of support will be appreciated.
Thanks in advance...

try this ,here....,FlickerHelper.java
public final class FlickrHelper {
