App crashes when trying to long press after swipe refreshing

I am trying to implement the recycler-view-selection library in android, I have implemented most of it, but I am facing an issue when I am trying to refresh my screen. After refreshing my screen using SwipeRefresh, if I try to long press an item in my recycler view the app keeps crashing and I receive this error.

This how I set my onRefreshListener
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
resetTracker();
getPendingCarts();
}
});
getPendingCarts method -
public void getPendingCarts()
{
swipeRefreshLayout.setRefreshing(true);
String token = SharedPrefUtil.getInstance().getApiToken(getActivity());
Call<ResponsePendingCart> call = ApiClient.getInstance().getPendingCarts(token);
call.enqueue(new Callback<ResponsePendingCart>() {
#Override
public void onResponse(Call<ResponsePendingCart> call, Response<ResponsePendingCart> response) {
try{
ResponsePendingCart pendingCart = response.body();
if(pendingCart.getStatus() == -1)
{
HelperClass.getInstance().forceLogout(getActivity());
}
else
{
List<Order> items = pendingCart.getItems();
if(items == null || items.size()==0)
{
container_no_order.setVisibility(View.VISIBLE);
rview_ongoing.setVisibility(View.INVISIBLE);
}
else
{
container_no_order.setVisibility(View.INVISIBLE);
rview_ongoing.setVisibility(View.VISIBLE);
AppData.shopCurrency = Html.fromHtml(pendingCart.getItems().get(0).getShop().getCurrencyHtmlCode()).toString();
for (Order item : items ) {
try{
List<ShopPromotion> promotions = item.getShopPromotion();
for (ShopPromotion promotionItem: promotions) {
List<FreeDishItem> dishItem = promotionItem.getFreeDish();
if (dishItem != null) {
for (int i = 0; i < dishItem.size() && dishItem.get(i) != null; i++) {
Dish orderItemListItem = new Dish();
orderItemListItem.setTitle(dishItem.get(i).getTitle());
orderItemListItem.setQuantity(dishItem.get(i).getQuantity());
orderItemListItem.setDetails(dishItem.get(i).getDetails());
orderItemListItem.setPrice(0.00);
orderItemListItem.setIsFreeDish(1);
item.getOrderItemList().add(orderItemListItem);
}
}
}
}
catch (Exception e) {
FirebaseCrashlytics.getInstance().log(e.toString());
}
}
if(listAdapter == null)
{
listAdapter = new OngoingListAdapter(getActivity(),items);
rview_ongoing.setAdapter(listAdapter);
rview_ongoing.setLayoutManager(new LinearLayoutManager(getActivity()));
int resId = R.anim.layout_animation_from_bottom;
LayoutAnimationController animation = AnimationUtils.loadLayoutAnimation(getActivity(), resId);
rview_ongoing.setLayoutAnimation(animation);
initSelectionTracker(listAdapter,rview_ongoing);
swipeRefreshLayout.setRefreshing(false);
}
else
{
OngoingListAdapter listAdapter = new OngoingListAdapter(getActivity(),items);
rview_ongoing.setAdapter(listAdapter);
rview_ongoing.setLayoutManager(new LinearLayoutManager(getActivity()));
initSelectionTracker(listAdapter,rview_ongoing);
swipeRefreshLayout.setRefreshing(false);

}
}
swipeRefreshLayout.setRefreshing(false);
}
catch (Exception e)

FirebaseCrashlytics.getInstance().log(e.toString());
}
}
#Override
public void onFailure(Call<ResponsePendingCart> call, Throwable t) {

}
});
}
initSelectionTracker works as such -
public void initSelectionTracker(OngoingListAdapter adapter,RecyclerView recyclerView){
OngoingListItemKeyProvider keyProvider = new OngoingListItemKeyProvider(adapter);
OngoingListItemDetailsLookup itemDetailsLookup = new OngoingListItemDetailsLookup(recyclerView);
StorageStrategy<Order> storageStrategy = StorageStrategy.createParcelableStorage(Order.class);
SelectionTracker.SelectionPredicate<Order> selectionPredicate = new SelectionTracker.SelectionPredicate<Order>() {
#Override
public boolean canSetStateForKey(#NonNull Order key, boolean nextState) {
return key.getService() == 1 && tracker.getSelection().size()<2;
}
#Override
public boolean canSetStateAtPosition(int position, boolean nextState) {
return listAdapter.getItem(position).getService() == 1 && tracker.getSelection().size()<2;
}
#Override
public boolean canSelectMultiple() {
return true;
}
};
tracker = new SelectionTracker.Builder<Order>(
"my-selection-id",
recyclerView,
keyProvider,
itemDetailsLookup,
storageStrategy).withSelectionPredicate(selectionPredicate)
.build();
adapter.setTracker(tracker);
tracker.addObserver(new SelectionTracker.SelectionObserver<Order>() {
#Override
public void onSelectionChanged() {
try{
super.onSelectionChanged();
selectedItems = tracker.getSelection().size();
if(selectedItems>0){
try{
setActionBarTitle(String.format("%d Order(s) Selected",selectedItems));
Selection<Order> selections = tracker.getSelection();
for(Order selectedOrder:selections){
selectedOrders.add(selectedOrder.getTemporaryOrderId());
}
}catch (Exception e){
FirebaseCrashlytics.getInstance().log(e.toString());
}
}else{
tracker.clearSelection();
selectedOrders.clear();
setActionBarTitle("Ongoing");
}
getActivity().invalidateOptionsMenu();
}catch (Exception e){
e.printStackTrace();
}
}
});
}

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);
}
} 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();

Register a new user on ejabberd server in android

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.

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:
