我想在android手机上读去服气端的数据 服务器是用servlet做的 在浏览器里能正常读到servlet的反馈信息 一到手机上就不行 下面是我android代码：
HttpClient client=new DefaultHttpClient();
String url="http://127.0.0.1:9090/MusicPlayer/getMusicName?pageSize=2";
HttpGet get=new HttpGet(url);
try {
HttpResponse response=client.execute(get);
HttpEntity entity=response.getEntity();
BufferedReader reader=new BufferedReader(new InputStreamReader(entity.getContent()));
StringBuffer buffer=new StringBuffer();
String line=null;
while((line=reader.readLine())!=null){
buffer.append(line+"\n");
}
reader.close();
try {
StringBuffer b2=new StringBuffer();
JSONArray ja=new JSONArray(buffer.toString());
for(int i=0;i<ja.length();i++){
JSONObject jb=ja.getJSONObject(i);
b2.append(ja.getString(i));
}
//tv.setText(b2.toString());
Log.w("result", b2.toString());
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (ClientProtocolException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
下面是异常信息：
