我的android应用程序无法与我的PHP文件建立连接

Question

我在我的WAMP服务器中创建了一个只播放音频的php文件，现在我正在尝试将我的Android应用程序与我的php文件连接，但显然我的response = httpclient.execute(request)为空。 有什么办法可以得到答复吗？我正在创建一个音频流应用程序顺便说一句。 和平。

MainActivity.java

MediaPlayer playMusic;

//To connect PHP files 
HttpClient httpclient;
HttpGet request;
HttpResponse response;
String url;
