android什么叫服务器,android - 我的Android Apk的服务器URL是什么？ - SO中文参考 - www.soinside.com...
[我正在使用PHP JSON Volley来验证我的登录活动。目前，我正在提供localhost和IP地址来测试我的应用程序(请在下面找到我的代码)。但是，当生成APK时，应提供什么URL？请指导。public class LoginActivitywithConnection extends Activity {
private static final String TAG = "LoginActivitywithConnection";

private Button btnLinkToRegister;

private EditText inputPassword;
private ProgressDialog pDialog;

if (data != null) {
String buttonClicked = data.getString("ButtonClicked");
if (buttonClicked.equals("asha")) {

String password = inputPassword.getText().toString().trim();
// Check for empty data in the form

DefaultRetryPolicy retryPolicy = new DefaultRetryPolicy(0, -1, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
strReq.setRetryPolicy(retryPolicy);
// Adding request to request queue
AppController.getInstance().addToRequestQueue(strReq, tag_string_req);
}
常量类：public class Constants {
private static final String ROOT_URL ="http://192.168.43.6/Android/v1/";
// Server user login url
public static String URL_LOGIN = ROOT_URL+"ashaLogin.php";
}
当用户下载此apk时，服务器URL(非本地)将是什么？
