android permission问题

【华为云1024程序员节·向云而生】预约直播 抽14件华为电子产品礼包！>>>

我想做一个网络测试，在电脑本地搭建好了环境（通过浏览器可正常访问），然后我在android模拟器中测试访问，出现了java.net.SockException:Permission Deny (maybe missing INTERNET permission)错误，关键是，我在AndroidMainfest.xml文件中添加了INTERNET权限！好诡异的问题，求教

贴上代码

java代码：

package weather.test;

import java.io.BufferedReader;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.net.HttpURLConnection;

import java.net.URL;

import org.apache.http.HttpConnection;

import org.apache.http.HttpResponse;

import org.apache.http.client.HttpClient;

import org.apache.http.client.methods.HttpGet;

import org.apache.http.impl.client.DefaultHttpClient;

import android.app.Activity;

import android.graphics.Color;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.ListView;

import android.widget.TextView;

import android.widget.Toast;

public class WeatherActivity extends Activity {

private TextView mEditText;

private Button mButton;

private ListView mListView;

private String mUrl = "http://www.google.com/ig/api?weather=";

private OnClickListener clickListener = new View.OnClickListener() {

@Override

public void onClick(View arg0) {

// TODO Auto-generated method stub

String query = mEditText.getText().toString();

updateListView(query);

}

};

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        mEditText = (TextView) findViewById(R.id.editText);

        mButton = (Button) findViewById(R.id.button);

        mButton.setOnClickListener(clickListener);

    }

    private void updateListView(String city) {

     String xml = getXmlData(city);

     TextView textView = (TextView) findViewById(R.id.textView);

     textView.setText(xml);

    }

    private String getXmlData(String city) {

     URL url;

     String data = "the result is: ";

     HttpClient client = new DefaultHttpClient();

     HttpGet httpGet = new HttpGet("http://10.0.2.2:82/test/os.php");

     try {

     HttpResponse response = client.execute(httpGet);

     }catch(Exception e) {

     Toast.makeText(WeatherActivity.this, "error:"+e.toString(),Toast.LENGTH_LONG).show();

     }

return data;

    }

}

AndroidManifest.xml代码

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="weather.test"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="7" android:targetSdkVersion="7" />

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

    <application

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name" >

        <activity

            android:name=".WeatherActivity"

            android:label="@string/app_name" >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

    </application>

</manifest>

我是在模拟器中运行的，出现如下错误

求高手赐教
