这是我的android代码，使用task1连接到我的数据库。任何人都可以帮我解决我的问题。感谢大家。它也适用于localhost。 ：）

每当我在我的机器人上键入正确的登录信息时，它总是以我的else语句结束，但是当我使用http://carkila.esy.es/index.php登录我的网络时，它正在工作。

答案 0 :(得分：0)
您正在将请求发送到错误的页面。您的index.php不是负责处理POST数据的人，authenticate.php。
所以，改变你的代码：
task1.execute("http://carkila.esy.es/index.php");
为：
task1.execute("http://carkila.esy.es/authenticate.php");
