Register.java
activity_register.xml
Home.java
activity_home.xml
Make sure the web service is already running on the server. Also change the IP 192.168.1.8 in the URL with the IPv4 of your local system. You can find the IPv4 in windows by typing ipconfig command in command prompt.
Finally run and test the project.
