这是我的java代码 

HttpGet httpGet = new HttpGet("http://myip:8084/rest/loc/test/7225");
    HttpParams params = new BasicHttpParams();
    HttpConnectionParams.setStaleCheckingEnabled(params, false);
    HttpConnectionParams.setConnectionTimeout(params, 30000);
    HttpConnectionParams.setSoTimeout(params, 30000);
    HttpClient httpClient = new DefaultHttpClient(params);
    HttpResponse httpResponse = httpClient.execute(httpGet);
    InputStream inputStream = httpResponse.getEntity().getContent();
    BufferedReader bufferedReader = new BufferedReader(
            new InputStreamReader(inputStream));
    StringBuilder responseStr = new StringBuilder();
    String responseLineStr = null;
    while ((responseLineStr = bufferedReader.readLine()) != null) {
        responseStr.append(responseLineStr);
    }

这是我的清单文件权限列表 

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/>
<user-permission android:name="android.permission.INTERNET"/>
<user-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

这可能是什么原因，服务正常
谢谢

与其为模拟器提供myip，不如给10.0.2.2. 那应该行得通。

我解决了这个问题，这是一个权限问题，它真的很像一个语法问题，你们都可以在我的第一篇文章中看到它，在 Manifest 文件中 

<user-permission android:name="android.permission.INTERNET"/>

错了，应该是

<uses-permission android:name="android.permission.INTERNET"/>

感谢所有回复，并为我的错误感到抱歉
