android NetworkMonitor和ConnectivityService记录

一、NetworkMonitor

packages/modules/NetworkStack/src/com/android/server/connectivity/NetworkMonitor.java

网络上都叫网络可用性校验，在WIFI和数据（以太网切换中使用）

有多个状态机

方法：isCaptivePortal

11-03 12:01:17.885  2535  4681 D NetworkMonitor/100: isCaptivePortal: isSuccessful()=false isPortal()=false RedirectUrl=null isPartialConnectivity()=false Time=23029ms

类 EvaluationState下的reportEvaluationResult

----------------------------------------------------------------------------------------------------------------------

父类下的notifyNetworkTested，会将校验结果发送给ConnectivityService

private final INetworkMonitorCallbacks mCallback;
private void notifyNetworkTested(NetworkTestResultParcelable result) {mCallback.notifyNetworkTestedWithExtras(result);
}

ConnectivityService.java里有个子类NetworkMonitorCallbacks 重写了notifyNetworkTestedWithExtras

NetworkMonitorCallbacks是在registerNetworkAgent里注册的

mDeps.getNetworkStack().makeNetworkMonitor(nai.network, name, new NetworkMonitorCallbacks(nai));
