android下httpd 代理设置和webview代理设置
在一些android上上设置httpd代理比较简单，可以通过wlan下长按对应的wifi链接点，出现修改网络配置，然后选择显示高级选项，在代理设置里面选择手动，然后出现界面可以设置代理服务器ip和端口。
网络有些说可以通过下面方式来设置，但这个毕竟面向开发人员
1
、adb连接上target
adb kill-server
adb connect target-ip
adb shell
2
、切换到数据库文件目录
cd /data/data/com.android.providers.settings/databases
3
、使用 sqlite3 连接这个数据文件
sqlite3 settings.db
4
、利用Insert语句往system表中插入proxy的设置
ex: INSERT INTO system VALUES(_id,
'http_proxy'
,
'IPAddress:port'
);
INSERT INTO system VALUES(
2012
,
'http_proxy'
,
'192.168.10.245:3128'
);
5
、确认修改,使用
'SELECT * FROM system'
来查看一下我们插入的配置
SELECT * FROM system;
但是一些android手机不支持，而且如果我们想通过代码中webview来强制设置代理，以便我们在开发环境可以通过绑定来在手机做调试。在android1.6之前的api中有有直接的方法来对webview设置代码，但是在之后的API中去掉了。所以只能寻求别的方法来设置代码.
下面通过webview的反射来实现

try

Object requestQueueObject = getRequestQueue(ctx);
if
(requestQueueObject !=

) {
// Create Proxy config object and set it into request Q

setDeclaredField(requestQueueObject,

f.set(obj, value);
}
private

throws
Exception {

Class c = object
instanceof
Class ? (Class) object : object.getClass();
if
(types !=

) {
Method method = c.getMethod(methodName, types);
out = method.invoke(object, params);
}
else
{
Method method = c.getMethod(methodName);
out = method.invoke(object);
}
// System.out.println(object.getClass().getName() + "." + methodName +
// "() = "+ out);
return
out;
}
}
然后在我们通过webview加载网页的activity设置如下，在oncreate方法里面通过 ProxySetting.setProxy(this.getApplicationContext(), "30.125.11.145", 7100);设置代理服务器为30.125.11.145,端口为7100，然后我们在加载loadurl(wv,"http://30.125.11.145:7100/mbrand/brand2.htm"); http://30.125.11.145:7100/mbrand/brand2.htm 这个页面后，这个页面的相关styel，image的请求都会转发到30.125.11.145,端口为7100这个代理服务器上，然后再这个代理服务器再做转发，即可实现手机端的测试环境样式和应用绑定都可以用的问题。
