开发的android应用程序无法连接到phpmyadmin

概述我正在用 eclipse开发一个应用程序.我试图将用户键入的数据存储到phpmyadmin中的数据库中.不幸的是,在用户点击提交按钮后,没有响应,数据也没有存储在我的数据库中. 这是我的java文件： import java.util.ArrayList;import java.util.List;import org.apache.http.NameValuePair;import or 我正在用 eclipse开发一个应用程序.我试图将用户键入的数据存储到phpmyadmin中的数据库中.不幸的是,在用户点击提交按钮后,没有响应,数据也没有存储在我的数据库中.

这是我的java文件：

我的PHP文件：

@H_301_13@<?PHP$response = array();require_once __DIR__ . '/db_connect.PHP';$db = new DB_CONNECT();if (isset($_GET['name']) && isset($_GET['username']) && isset($_GET['email']) && isset($_GET['password'])) {$name = $_GET['name'];$username = $_GET['username'];$email = $_GET['email'];$password = $_GET['password'];// MysqL inserting a new row$result = MysqL_query("INSERT INTO register(name,username,email,password) VALUES('$name','$username','$email','$password')");// check if row inserted or notif ($result) { // successfully inserted into database $response["success"] = 1; $response["message"] = "You are successfully registered to MEMS."; // echoing JsON response echo Json_encode($response);} else { // Failed to insert row $response["success"] = 0; $response["message"] = "Oops! An error occurred."; // echoing JsON response echo Json_encode($response);}} else {// required fIEld is missing$response["success"] = 0;$response["message"] = "required fIEld(s) is missing";// echoing JsON responseecho Json_encode($response);}?>

日志猫如下：

@H_301_13@11-25 10:37:46.772: I/Choreographer(638): Skipped 30 frames! The application may be doing too much work on its main thread.解决方法 首先,遵循Java命名约定并保持方法名称以小写字母开头.

其次,您必须获取networkonmainthreadException,因为您正在UI线程上执行阻止网络 *** 作.你做到了,你会度过一段美好的时光.

将所有网络代码放在异步任务中,或至少放在一个单独的线程中.
