Android出现java.net.SocketException: Permission denied的问题

1. 在AndroidMainfest.xml中加入以下
<uses-permission android:name="android.permission.INTERNET"/>
2. AndroidMainfest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="android.test"
      android:versionCode="1"
      android:versionName="1.0">
	<uses-sdk android:minSdkVersion="7"></uses-sdk> 
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".Main"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
