我总结一下,ss/ssr的目的就是用来翻q的,侧重于流量混淆加密,穿透防火q是第一位,使用socket5代理。而的目的是用来加密企业数据的,安全是第一位,本意并非是翻q
对于来说安全是第一位的,而对于ss/ssr来说穿透防火q是第一位,抗干扰性强,而且对流量做了混淆,(所有流量在通过防火q的时候,基本上都被识别为普通流量,也就是说你翻q了,但是相关部门是检测不到你在翻q的。)两者的出发点和着重点就不同,ss/ssr更注重流量的混淆加密。

AdMob 是移动电话广告市场,可提供用户在移动电话网络上播放广告。2006年创建,2009年被谷歌收购。
Admob覆盖200多个国家,是美国最大的手机广告平台。
这里建议看官方文档,非常详细,几乎是傻瓜式教学。点这里进入官方文档
我这里说一下我一开始遇到的两个坑,都很简单,但是我当时没注意到
一开始我一直在纠结这个报错,后来才发现,AdRequest
后面不用加括号。也算长个记性吧
这里一共有两个id,一个id是应用级id,是加在Manifest文件中的,另外一个id是控件级id,是加在控件的属性上的。
前者是
后者是
上面是横幅广告,是谷歌官方推荐新手学的,我用的是插页式广告。我把官方文档的demo摘取下来了。在这里我把他分析一下
xml中还是官方文档当中的布局,我这里只显示MainActivity中的
布局是这样的,最上面是广告,下面有个TextView
,左下角是个Button
,右下角是个TextView
大体流程是这样:首先启动Activity
,执行生命周期函数,然后在onCreate
中进行初始化和广告对象InterstitialAd
的赋值,然后利用倒计时工具CountDownTimer
,倒计时3s后(期间右下角的TextView
会更新剩余时间,从3s开始,直到0s),左边的Button
才显示出来。点击Button
的时候,会先判断广告对象是否为null
,如果不为null
,就显示广告,如果为null
,就重新加载广告,然后倒计时3s,结束后,显示按钮。
在这里我做了个测试,就是切换到广告页面和切回MainActivity
,发现分别调用了onPause
和onResume
。所以我猜测,广告页面不是新的Activity
,切回的时候,会调用Activity
的生命周期函数onResume
执行效果如下
切回MainActivity
的时候,广告对象InterstitialAd
又为null
了。我猜测是调用广告页面的时候,即调用show
方法的时候,会对广告对象赋值为null
。
