I want to make a client-server android application. Specifically, they will both behave as a client and as a server as well. In simple words, I want two apps, who should be able to send data (Email address, login credentials, and anything I want to send) via the Internet. I checked for such an app on Github but unable to find one. Any leads would be really helpful. Thanks in advance

The simplest way to achieve this is using a server to store the data from both apps. Suppose you have 2 apps, the App A and the App B.

Use case
App A want to send info to App B.
Solution App A -> Server -> App B.

Use case App B want to send info to App A. Solution App B -> Server -> App A.

If you want to communicate the apps directly and the devices are in the same network you can check this: App that will communicate between devices connected on the same local network Wi-Fi

if you build a client-server system of an andriod app in any apps you are new to open android studio create a project file and the inner main file have app.java or app.kln. write code for building applications and run perfectly . that is the basic stap way to building app development.
