我收到錯(cuò)誤消息java.net.SocketException：套接字失?。篍ACCES（權(quán)限被拒絕）當(dāng)我嘗試應(yīng)用以下代碼時(shí)。這是我調(diào)用的函數(shù)，并給了我這個(gè)例外。public void run() {    // TODO Auto-generated method stub    URL myurl = null;    try {        myurl = new URL("http://10.0.2.2/list.JSON");    }    catch (MalformedURLException e) {        // TODO Auto-generated catch block        e.printStackTrace();    }    try {        URLConnection myconn = myurl.openConnection();        InputStream in = new BufferedInputStream(myconn.getInputStream());        InputStreamReader reader = new InputStreamReader(in);        BufferedReader br = new BufferedReader(reader);        String line;        StringBuilder sb = new StringBuilder();        while ((line=br.readLine()) != null)        {            sb.append(line);            //Toast.makeText(getApplicationContext(), "I enter here", Toast.LENGTH_LONG).show();        }        jsoncode = sb.toString();    }    catch (IOException e) {        // TODO Auto-generated catch block        e.printStackTrace();    }    threading = true;    super.run();}這是我的清單文件：<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.apk"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk android:minSdkVersion="14" />    <permission android:name="android.permission.INTERNET"></permission>    <application        android:icon="@drawable/ic_launcher"        android:label="@string/app_name" >        <activity            android:name=".PItestActivity"            android:label="@string/app_name" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>        <activity android:name="addfriend"></activity>        <activity android:name="updateDetails"></activity>        <activity android:name="Details"></activity>    </application></manifest>我該如何解決這個(gè)問題？
