下面是我的代碼

public class DownloadTask extends AsyncTask<String , Void, Void>
{
@Override
protected Void doInBackground(String... url) {
String playlistFetchUrl = url[0];
try {
String data = downloadUrl(playlistFetchUrl);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
}
private String downloadUrl(String StrUrl) throws IOException{
HttpURLConnection urlConnection = null;
InputStream isStream = null ;
String data = "";
try {
URL url = new URL(StrUrl);
// Creating an http connection to communicate with url
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.connect();
isStream = urlConnection.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(isStream));
StringBuffer sb = new StringBuffer();
String line = "";
while((line = br.readLine()) != null){
sb.append(line);
}
data = sb.toString();
br.close();
} catch (MalformedURLException e) {
e.printStackTrace();
}
catch(IOException e){
e.printStackTrace();
}
catch(Exception e){
e.printStackTrace();
}
finally{
isStream.close();
urlConnection.disconnect();
}
return data ;
}
and logcat is：
