What is the correct way to receive data from a server?

Question

Ok so to explain I have server in Java that receives data from a C++ program that I have no control over. So the data is transferred over TCP/IP and the Java server just receives it. The volume of incoming data is huge and it comes at a very fast rate, just imagine a terminal printing loads of lines really fast.. I don't need to get all of it, just as much as I can would be great..

Now I need to send that data to an android device and display it. I have no idea what is the best approach to so this.

I am currently pinging the server from my android device every 50ms using an executor. Then I use a handler to display the data. I have already posted a question with code here: related question.

Obviously the android app will need to ping it while the app is running so I can't avoid the while(true) scenario.

I have read about 100000000 ways to do concurrency in Android, and I do not know what to choose for this.

I tried simple Threads, they were to hard to manage.
I am now running a ExecutorService
I also read about ScheduledExecutorService, but they need a time duration right ? My app can be running for 5 hours or 5 minutes or 5 years.
I read about HandlerThreads too, but I am not sure they are ideal for this scenario.

Any help would be great.

It really seems as though you want to be writing a Service in Android. Within that service there are many options, but if you are constantly waiting for data on the mobile device, then a ServerSocket can be left open to receive data as it comes across until you close it. — Jay Snayder, Jun 27 '18 at 11:51
@JaySnayder like I am doing now right ? ExecutorService ? I already have a Socket setup and open, and an InputStreamReader to do all the receiving — Trt Trt, Jun 27 '18 at 12:01
@KarmelinaMichael Is socket.io able to receive such a big amount of data ? — Trt Trt, Jun 27 '18 at 12:04
This question is off-topic here, because of causes opinion based answers. @Jure is right, try there — Marc Estrada, Jun 27 '18 at 12:23
@MarcEstrada is it opinion based ? there must be 1 correct answer.. — Trt Trt, Jun 27 '18 at 12:26
When a title starts with "What is the best way" this is now opinion based, since there are a lot of solutions to one problem and best or worst, there are opinion based answers — Marc Estrada, Jun 27 '18 at 12:30
