Android Question Transferring data to the server

[red30]

I have a GMS module which can work with MQTT and Web Service. I need to get data from it and store it somewhere. As I understood from the forum, I cannot run my own MQTT server. So I settled on Web Service.
I imagine it like this: on an Android or Windows device, I run a server that I can access via GET or POST to transfer data. I also wanted to be able to connect to this server using a separate application and read the data.
How can I do it better? Is it possible to create such a server using B4A or B4J?

B4A no. B4J Yes. But you need a server which is able to run B4J-Apps.

You told you cannot run your own MQTT so you used a webservice.
The webservice can not run java-apps, right?
In that case you can not run B4J apps as well.

You need a Server or a VPS to run java (B4J) Apps. On this server you even can install a MQTT-Broker.

As I understood from the forum, I can run my own MQTT, but only within the same network. I want clients to be able to connect from various devices that are not within this network ... As I understand it, in this case, I can only rent a server?
That's why I made the decision to use a web service.

and limit yourself using php or similar solutions.

I suggest to rent a VPS. There are cheap ones available. If you are ok with Linux servers it can be relatively cheap ($5 approx)

Windows VPS are more expensive. But even here you can get a small one under $10/Month.

where do you can run the MQTT? On your pc? Why you can only connect to it from within the same network?

I'm a little confused... Do you think it's better to use MQTT and rent a server?

I used this example. My phone was connected to Wi-Fi. And all PCs and phones connected to this network could work. But if I try to connect my phone via mobile internet to this server, I won't be able to do it.

you need to configure a portforwarding in your router to route the request to your local server.

Maybe your firewall is blocking something?

Regarding MQTT or not.
You can use whatever technology you are most familar with. It is up to you to use MQTT or REST (jserver).
On webhostings you are most probably limited in what you can and what not.
