eventsource-android returns empty data String from Flux server endpoint

I have successfully implemented this github library for SSE Handling in Android.
The problem
Each time i'm sending data to the stream , the onMessage function is triggered successfully. Although the provided data field of MessageEvent is empty.
My Implementation
Main.java
private SSEHandler sseHandler = new SSEHandler();
private EventSource eventSource;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startEventSource();
}
private void startEventSource() {
eventSource = new EventSource.Builder(".../ambulance/assign/receive")
.eventHandler(sseHandler)
// .headers()
.build();
eventSource.connect();
}
private void stopEventSource() {
if (eventSource != null)
eventSource.close();
sseHandler = null;
}
SSEHandler.java
public class SSEHandler implements EventSourceHandler {
public SSEHandler() {}
#Override
public void onConnect() {
Log.e("SSE Connected", "True");
}
#Override
public void onMessage(String event, MessageEvent message) {
Log.e("SSE Message", event);
Log.e("SSE Message: ", String.valueOf(message));
}
#Override
public void onComment(String comment) {
//comments only received if exposeComments turned on
Log.e("SSE Comment", comment);
}
#Override
public void onError(Throwable t) {
//ignore ssl NPE on eventSource.close()
Log.e("SSE Error", "Error");
}
#Override
public void onClosed(boolean willReconnect) {
Log.e("SSE Closed", "reconnect? " + willReconnect);
}
}
Server Side Endpoint
#RequestMapping(method = RequestMethod.GET, value = "/ambulance/assign/receive")
public Flux < MessageEvent > addReport() {
return Flux.create(sink -> {
assignProcessor.register(sink::next);
});
}
No matter what is the return type of Flux <Object> the data field
is always empty on android
POST payload & MessageEvent Object
Payload
{
"data": "test",
"lastEventId": "tester",
"origin": "my origin"
}
MessageEvent.java
public class MessageEvent {
public String data;
public String lastEventId;
public String origin;
public MessageEvent(String data, String lastEventId, String origin) {
this.data = data;
this.lastEventId = lastEventId;
this.origin = origin;
}
public MessageEvent(String data) {
this(data, null, null);
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
MessageEvent that = (MessageEvent) o;
if (data != null ? !data.equals(that.data) : that.data != null) return false;
if (lastEventId != null ? !lastEventId.equals(that.lastEventId) : that.lastEventId != null) return false;
if (origin != null ? !origin.equals(that.origin) : that.origin != null) return false;
return true;
}
#Override
public int hashCode() {
int result = data != null ? data.hashCode() : 0;
result = 31 * result + (lastEventId != null ? lastEventId.hashCode() : 0);
result = 31 * result + (origin != null ? origin.hashCode() : 0);
return result;
}
#Override
public String toString() {
return "MessageEvent{" +
"data='" + data + '\'' +
", lastEventId='" + lastEventId + '\'' +
", origin='" + origin + '\'' +
'}';
}
}
Already tried with : Flux <String> data is still empty.
Based on this EventStreamParser I assume that it should parse as data every Object in JSON format because of this function.
private void processField(String field, String value)
I even tried plain text, but didn't seem to work either...

I managed to read the Object using another java library
This one:
Maven
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>4.7.2</version>
</dependency>
Gradle
// https://mvnrepository.com/artifact/com.squareup.okhttp3/okhttp
compile group: 'com.squareup.okhttp3', name: 'okhttp', version: '4.7.2'
Buildr
# https://mvnrepository.com/artifact/com.squareup.okhttp3/okhttp
'com.squareup.okhttp3:okhttp:jar:4.7.2'
Implemented EventSource as before
public class SimpleEventHandler implements EventHandler {
#Override
public void onOpen() throws Exception {
System.out.println("onOpen");
}
#Override
public void onClosed() throws Exception {
System.out.println("onClosed");
}
#Override
public void onMessage(String event, MessageEvent messageEvent) throws Exception {
System.out.println(messageEvent.getData());
}
#Override
public void onComment(String comment) throws Exception {
System.out.println("onComment");
}
#Override
public void onError(Throwable t) {
System.out.println("onError: " + t);
}
}
Main method
public static void main(String[] args) throws InterruptedException, ExecutionException, UnknownHostException, IOException {
EventHandler eventHandler = new SimpleEventHandler();
String url = String.format("https://aedproject.herokuapp.com/api/ambulance/assign/receive");
EventSource.Builder builder = new EventSource.Builder(eventHandler, URI.create(url))
.reconnectTime(Duration.ofMillis(3000));
try (EventSource eventSource = builder.build()) {
eventSource.start();
TimeUnit.MINUTES.sleep(10);
} catch (Exception e) {
}
This time, the data filed of MessageEvent contains my whole Object!

loadInitial method not getting called in PositionalDataSource<Item>

I'm implementing PositionalDataSource from Paging Library in Java and getting an issue that constructor of PositionalDataSource's child class is getting called but after that loadInitial method is not getting called.
public HistoryPositionalDataSource(List<CallTable> callLogs)
{
this.callLogs = callLogs;
Log.d("PaginationDataSource", "Constructor");
}
#Override
public void loadInitial(#NonNull LoadInitialParams params, #NonNull LoadInitialCallback callback) {
Log.d("PaginationDataSource", "loadInitial");
if (callLogs!=null && !callLogs.isEmpty())
{
int totalCount = computeCount();
int position = computeInitialLoadPosition(params, totalCount);
int loadSize = computeInitialLoadSize(params, position, totalCount);
callback.onResult(loadRangeInternal(position, loadSize), position, totalCount);
}
}
#Override
public void loadRange(#NonNull LoadRangeParams params, #NonNull LoadRangeCallback callback) {
callback.onResult(loadRangeInternal(params.startPosition, params.loadSize));
}
Here's my PageListConfig
private void init() {
pagedListConfig = (new PagedList.Config.Builder()).setEnablePlaceholders(true)
.setInitialLoadSizeHint(Integer.MAX_VALUE).setPageSize(Integer.MAX_VALUE).build();
Executor executor = Executors.newFixedThreadPool(3);
List<CallTable> listLogs = getCallLogs(context);
historyDataSourceFactory = new HistoryDataSourceFactory(listLogs);
LivePagedListBuilder livePagedListBuilder = new LivePagedListBuilder(historyDataSourceFactory, pagedListConfig);
pagedCallLogs = livePagedListBuilder
.setFetchExecutor(executor)
.build();
}
Factory class:
public class HistoryDataSourceFactory extends DataSource.Factory {
private static final String TAG = HistoryDataSourceFactory.class.getSimpleName();
private HistoryPositionalDataSource historyPositionalDataSource;
public HistoryDataSourceFactory(List<CallTable> callLogs)
{
if (callLogs!=null && !callLogs.isEmpty())
{
Log.d("PaginationFactory", "NotNullLogs");
historyPositionalDataSource = new HistoryPositionalDataSource(callLogs);
}
}
#Override
public DataSource create() {
return historyPositionalDataSource;
}
}
My getPagedCallLogs method:
public synchronized LiveData<PagedList<CallTable>> getPagedCallLogs() {
if (pagedCallLogs!=null && pagedCallLogs.getValue()!=null)
{
Log.d("PagingGetData", "Done");
return pagedCallLogs;
}
else
{
Log.d("PagingGetData", "Null");
return null;
}
}
Logs image is given below.

Load size and offset is set
via PagedList.Config so you don't need to calculate load range yourself.
Change your loadInitial function
#Override
public void loadInitial(#NonNull LoadInitialParams params, #NonNull LoadInitialCallback callback) {
Log.d("PaginationDataSource", "loadInitial");
if (callLogs!=null && !callLogs.isEmpty())
{
callback.onResult(loadRangeInternal(0, params.requestedLoadSize), 0);
}
}
Edit:
Try this config aswell
PagedList.Config config =
new PagedList.Config.Builder()
.setPageSize(50)
.setEnablePlaceholders(false)
.setPrefetchDistance(25)
.build();
Edit2:
Try changing extention from DataSource.Factory to DataSource.Factory<Integer, ModelClass> and PositionalDataSource to PositionalDataSource<ModelClass>

After too many struggle, I become able to resolve my issue. The issue was with my getPagedCallLog method.
I wrote:
public synchronized LiveData<PagedList<CallTable>> getPagedCallLogs() {
if (pagedCallLogs!=null && pagedCallLogs.getValue()!=null)
{
Log.d("PagingGetData", "Done");
return pagedCallLogs;
}
else
{
Log.d("PagingGetData", "Null");
return null;
}
}
I was taking Google I/O '18, in which he said that loadInitial is called by the pageList, then I realise that it wasn't getting called in my case. And it is working fine after removing pagedCallLogs.getValue()!=null which was my stupid mistake.
Now it looks like this:
public synchronized LiveData<PagedList<CallTable>> getPagedCallLogs() {
if (pagedCallLogs!=null)
{
Log.d("PagingGetData", "Done");
return pagedCallLogs;
}
else
{
Log.d("PagingGetData", "Null");
return null;
}
}

TimeoutException: Expected condition failed:waiting for util.Waiter (tried for 10 second(s) with 500 MILLISECONDS interval)

playframework-2.3 Akka-Async interaction porting?

I have some old playframework 2.2 java webservice that interacts with akka, and now I should port them to playframework 2.3.
However, async has been deprecated and even after reading the doc about the async porting (http://www.playframework.com/documentation/2.3.x/JavaAsync) I wasn't able to understand how to apply it to my case (code below):
I must make the await for a timeout/akka server reply before starting the construction of my reply (ok()), otherwise I will block the thread.
I should make the actorselection async too.
I should make the akka server reply parsing/reply construction async too
I looked around and I wasn't able to find an example of such interactions, even in typesafe templates.
How could I do that?
/* playframework 2.2 code */
public class Resolve extends Controller {
private final static String RESOLVER_ACTOR = play.Play.application().configuration().getString("actor.resolve");
#CorsRest
#VerboseRest
#RequireAuthentication
#BodyParser.Of(BodyParser.Json.class)
public static Result getJsonTree() {
JsonNode json = request().body().asJson();
ProtoBufMessages.ResolveRequest msg;
ResolveRequestInput input;
try {
input = new ResolveRequestInput(json);
} catch (rest.exceptions.MalformedInputException mie) {
return badRequest(mie.getMessage());
}
msg = ((ProtoBufMessages.ResolveRequest)input.getMessage());
ActorSelection resolver = Akka.system().actorSelection(RESOLVER_ACTOR);
Timeout tim = new Timeout(Duration.create(4, "seconds"));
Future<Object> fut = Patterns.ask(resolver, input.getMessage(), tim);
return async (
F.Promise.wrap(fut).map(
