首先原諒的英語不好。我對android應用程序開發頗爲陌生。所以幾個星期，我嘗試通過教程學習。 This one particular tutorial是在我的「我真的需要了解這一個」名單。所以我嘗試使用免費託管遠程服務器的教程，byethost。我想使用像wamp這樣的本地服務器，但是目前我的個人筆記本電腦壞了，所以我不得不使用我的辦公室筆記本電腦。無法從Android的增值遠程服務器
問題IM面是，我不能增加價值的服務器。我只更改了Config.java中的一些代碼，並使用dbConnect.php來連接我的服務器。
dbConnect.php
<?php
/*

My Database is androiddb
you need to change the database name rest the things are default if you are using wamp or xampp server
You may need to change the host user name or password if you have changed the defaults in your server
*/
//Defining Constants
define('HOST','sql106.byethost6.com ');
define('USER','#######');
define('PASS','#######');
define('DB','######');
//Connecting to Database
$con = mysqli_connect(HOST,USER,PASS,DB) or die('Unable to Connect');
Config.Java
public class Config {
//Address of our scripts of the CRUD
public static final String URL_ADD="https://benerin.byethost6.com/simpcoding/crud/addEmp.php";
public static final String URL_GET_ALL = "https://benerin.byethost6.com/simpcoding/crud/getAllEmp.php";
public static final String URL_GET_EMP = "https://benerin.byethost6.com/simpcoding/crud/getEmp.php?id=";
public static final String URL_UPDATE_EMP = "https://benerin.byethost6.com/simpcoding/crud/updateEmp.php";
public static final String URL_DELETE_EMP = "https://benerin.byethost6.com/simpcoding/crud/deleteEmp.php?id=";
//Keys that will be used to send the request to php scripts
public static final String KEY_EMP_ID = "id";
public static final String KEY_EMP_NAME = "name";
public static final String KEY_EMP_DESG = "desg";
public static final String KEY_EMP_SAL = "salary";
//JSON Tags
public static final String TAG_JSON_ARRAY="result";
public static final String TAG_ID = "id";
public static final String TAG_NAME = "name";
public static final String TAG_DESG = "desg";
public static final String TAG_SAL = "salary";
//employee id to pass with intent
public static final String EMP_ID = "emp_id";}
在我的logcat它按添加員工按鈕

誰能告訴我什麼是錯的呢？如果我在我的學習中跳得太遠，那麼理解這一點最好的開始是什麼？
謝謝回答，我會考慮它^^。 –
