I have a question about that. I even managed to create a webservice by eclipse with tomcat apache , mysql etc. But I always have to use the IP of my network for it to work.
I have an application in Java that stores the data of a marked query in the database. The function of App android and make a select and fetch this data. This already works, but only on my network, I would like it to work on 3G and 4G .
Can anyone help me with what I should do?
