将Android设备连接到在我的PC上运行的Tomcat服务器

Question

I am trying to connect with my device to the local Tomcat server by IP not with localhost. If I can work this out probably I will do it in Android too.

I know that I have to connect the device and PC to the same Wi-Fi.

I have a question: It's a problem if I connect to the internet with a proxy?

For example http://localhost:8080/create it's working on my PC when I deploy my app.

I tried to set Windows Firewall off or to create a new Rule(Inbound Rules) for port 8080 but it didn't work for me. When I tried to connect to the server from my PC using the IP(I got it from cmd -> ipconfig IPv4 ) it did't work(192.168.0.101:8080/create).

I read many post on stack about this even tried to add a new environment variable for JAVA ( JAVA_OPTS="-Djava.net.preferIPv4Stack=true" ). I did this in cmd with the command: setx _JAVA_OPTIONS -Djava.net.preferIPv4Stack=true and received SUCCESS: Specified value was saved. Even changed the server.xml in \\Tomcat 9.0\\conf. Here is my Connector:

 <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" 
               address="0.0.0.0"/>

I can access the server in the emulator with this IP: 10.0.0.2:8080/create. How I do it now for devices?? What I am missing. Can you guide me step by step how to do it?

How to fix the problem:

My tomcat is embedded so I created a file in /resources named application.properties and added: server.address=<http://192.168.0.101> and turned off Firewall.

Good luck!
