登录注册android app无法连接到本地服务器（连接被拒绝）

Question

This application registers users in a database. When I click the register button, I get Connection Refused error in my logs.

My login and register localhost IP is : 127.0.0.1. I searched many websites and articles and they wrote >> you should change 127.0.0.1 to 10.0.2.2 but finally I didn't succeed. My emulator is Nox player.

    // Server user login url
public static String URL_LOGIN = "http://127.0.0.1:80/android_login_api/login.php";

// Server user register url
public static String URL_REGISTER = "http://127.0.0.1:80/android_login_api/register.php";

Answer 1

Well ! Issue can be of the port you are referring to which is 80 in your case. You can try changing the port to 8080 . In that case the Addresses may look like this:

    // Server user login url
public static String URL_LOGIN = "http://127.0.0.1:8080/android_login_api/login.php";

// Server user register url
public static String URL_REGISTER = "http://127.0.0.1:8080/android_login_api/register.php";

Or try like this :

// Server user login url
public static String URL_LOGIN = "http://10.0.2.2:8080/android_login_api/login.php";

// Server user register url
public static String URL_REGISTER = "http://10.0.2.2:8080/android_login_api/register.php";

Double check:

1. Your local host must be up and listening and you should be able to
   hit the url in browser locally (if not then something is wrong with your local server)
2. Check INTERNET permission in your Manifest
3. Port you are listening to must be open for connections.
