[RK3399][Android7.1]平台连接Captive Portal wifi时自动跳转到登录界面
背景
原生sdk连接portal网络后，会在状态栏弹出“登录到Wlan网络”的通知，下来状态栏也会有此消息，但不会自动跳转到验证登录界面，下面代码就是实现自动跳转登录界面的代码
实现方法
1.刚开始在csdn找到通过浏览器实现自动跳转到登录界面，经验证确实是可以的，方法链接如下：
【定制Android系统】Android 7.1 实现连接 Captive Portal WiFi 时自动弹出登录页面
但我们的客户是不内置浏览器的，所以只能用其他方法了
2.通过查看源码frameworks/base/services/core/java/com/android/server/connectivity/NetworkMonitor.java
发现了一个更简单的方法，把点击通知栏“登录到Wlan网络”跳转到登录界面的操作(这里实际是启动了CaptivePortalLogin.apk，CaptivePortalLogin使用的是webwiew)，直接在代码里启动就好了。
补丁如下：
