无法在android中获取本地服务器JSON响应java.net.ConnectException：连接被拒绝

如何解决无法在android中获取本地服务器JSON响应java.net.ConnectException：连接被拒绝

当我在模拟器中使用IP：10.0.2.2时，它会获得完美的JSON响应。

现在我想在手机上进行测试。

我的服务器正在本地计算机上运行。我找到了本地计算机IP，并给URL像新的JsonTask（）。execute（“ http://192.168.x.xxx:8080/rsi/v1”）; 但是我无法获得JSON响应。

请找到以下代码：

MainActivity.java

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
      new JsonTask().execute("http://192.168.x.xxx:8080/rsi/v1");
    //new JsonTask().execute("http://127.0.0.1:8080/rsi/v1");//device
    //new JsonTask().execute("http://10.0.2.2:8080/rsi/v1");//emulator
}

private class JsonTask extends AsyncTask<String,String,String> {

    protected void onPreExecute() {
        super.onPreExecute();

        pd = new ProgressDialog(MainActivity.this);
        pd.setMessage("Please wait");
        pd.setCancelable(false);
        pd.show();
    }
    protected String doInBackground(String... params) {
        HttpURLConnection connection = null;
        BufferedReader reader = null;
        try {
            URL url = new URL(params[0]);

            connection = (HttpURLConnection) url.openConnection();
            connection.connect();
            InputStream stream = connection.getInputStream();
            reader = new BufferedReader(new InputStreamReader(stream));
            StringBuffer buffer = new StringBuffer();
            String line = "";

            while ((line = reader.readLine()) != null) {
                buffer.append(line + "\n");
                Log.d("TAG","socket===>res==>" + line);   //here u ll get whole response...... :-)
            }
            return buffer.toString();
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (connection != null) {
                connection.disconnect();
            }
            try {
                if (reader != null) {
                    reader.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return null;
    }

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);
        if (pd.isShowing()) {
            pd.dismiss();
        }
        //txtJson.setText(result);
        Log.d("TAG","socket====>result===>" + result);

    }
}

以如下方式获取logcat：

注意：当我输入链接（http://127.0.0.1:8080/rsi/v1）时，本地计算机的Web浏览器会获得正确的响应。

请问我做错了什么。
