我只是在android模拟器上做了一个基本的Webview应用程序，无法连接到我电脑上的网站。
下面是我的代码：
Android清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.emswebviewer"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="14"
    android:targetSdkVersion="19" />
<uses-permission android:name="android.permission.INTERNET"/>

主活动Java文件：

public class MainActivity extends Activity {
private WebView webView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
        System.out.println("*** My thread is now configured to allow connection");
    }
    setContentView(R.layout.activity_main);

    webView = (WebView) findViewById(R.id.webView);
    webView.loadUrl("http://10.0.2.2:8080");
}

终端（在本地主机端口8080上启动网站）：

Michaels-MacBook-Pro-5:web michael$ php -S localhost:8080
PHP 5.5.14 Development Server started at Mon Dec 22 14:08:01 2014
Listening on http://localhost:8080

httpd. conf文件（在Apache文件夹下）：

#
# This should be changed to whatever you set DocumentRoot to.
#
<Directory "/Applications/MAMP/htdocs">
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
#   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that "MultiViews" must be named *explicitly* --- "Options All"
# doesn't give it to you.
#
# The Options directive is both complicated and important.  Please see
# http://httpd.apache.org/docs/2.2/mod/core.html#options
# for more information.
#
Options All

#
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
#   Options FileInfo AuthConfig Limit
#
AllowOverride All

#
# Controls who can get stuff from this server.
#
Order allow,deny
Allow from all

我使用Mamp和AVD作为模拟器。
当我运行应用时，它在主活动页面上返回net：：ERR_CONNECTION_REFUSED。
我需要在某个地方允许外部连接吗？或者我正在尝试做的事情本质上有什么问题吗？
