Q:

Android to Wamp Server Connection using Android Studio and PHP

I'm newbie here. I want to connect my android app to wampserver database. I found a tutorial on this link, But where should I find my serverUrl in wampserver? It should look like this: private final String serverUrl = "your path here" So where do I find "your path here"?
Here is my code:
MainActivity.java

I am using WampServer with user="root" and password=""

A:

The "path" is probably the URL to your local web server, that is:
http://your_ip/your_path_to_your_php_script
