我在android应用程序中有一个简单的代码,在其中使用了一个简单的jsoup代码来连接到链接并获得在线电台的标题.但是,当我单击“播放”按钮时,我的应用程序崩溃退出.这是我的onClick动作：

btnPlay.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

progressDialog.show();

Document doc = null;

try {

doc = Jsoup.connect("http://info.radiostyle.ru/inc/getinfo.php?getcurentsong=20383&mount=lezgifm").get();

String s = doc.body().text();

System.out.println(s);

lblMusicName.setText(s);

} catch (IOException e) {

e.printStackTrace();

}

new Thread(new Runnable() {

@Override

public void run() {

if (radioBtn128.isChecked())

url = "http://stream4.radiostyle.ru:8004/lezgifm";

else if (radioBtn32.isChecked())

url = "http://stream0.radiostyle.ru:8000/lezgifm";

setStream(url);

isPlaying = true;

progressDialog.dismiss();

}

}).start();

}

});

当我尝试调试时,调试器在Document doc = null point中循环.怎么了？
