android NetworkMonitor记录

是否能上网的状态

上网url地址的设置：

NetworkMonitor.java

  makeCaptivePortalHttpsUrls

    config_captive_portal_https_urls

    DEFAULT_CAPTIVE_PORTAL_HTTPS_URLS

http准备监测

isCaptivePortal

        sendHttpAndHttpsParallelWithFallbackProbes 

                httpsProbe.start();
                httpProbe.start();

                isConclusiveResult(httpsResult, capportApiUrl) （也不知道为啥不是http）

        isCaptivePortal : isSuccessful()=(最后的日志)           

因为httpsUrls和http都有，所以调用sendHttpAndHttpsParallelWithFallbackProbes

05-20 19:38:33.611  1575  2888 I NetworkMonitor: isCaptivePortal, pacUrl = null
05-20 19:38:33.612  1575  2888 I NetworkMonitor: isCaptivePortal, httpsUrls = [Ljava.net.URL;@63b8da0 httpUrls = [Ljava.net.URL;@6423d59
05-20 19:38:33.612  1575  2888 I NetworkMonitor: isCaptivePortal, httpsUrls and httpUrls, sendHttpAndHttpsParallelWithFallbackProbes

探测开始是在 ProbingState类里的

enter 方法里，isCaptivePortal调用完成后，拿到CaptivePortalProbeResult结果后，发送

CMD_PROBE_COMPLETE消息

private class ProbingState extends State {public void enter() {mThread = new Thread(() -> sendMessage(obtainMessage(CMD_PROBE_COMPLETE, token, 0,isCaptivePortal(deps))));mThread.start();}public boolean processMessage(Message message) {switch (message.what) {case CMD_PROBE_COMPLETE:final CaptivePortalProbeResult probeResult =(CaptivePortalProbeResult) message.obj;if (probeResult.isSuccessful()) {//正常会走到这儿Log.i(TAG, "ProbingState, processMessage, CMD_PROBE_COMPLETE, isSuccessful");transitionTo(mEvaluatingPrivateDnsState);} else if (probeResult.isPortal()) {mEvaluationState.reportEvaluationResult(                                                NETWORK_VALIDATION_RESULT_INVALID,probeResult.redirectUrl);mLastPortalProbeResult = probeResult;transitionTo(mCaptivePortalState);}else {//最后匹配到这儿，就是连接不成功了Log.i(TAG, "ProbingState, processMessage, CMD_PROBE_COMPLETE,else NETWORK_VALIDATION_FAILED ");mEvaluationState.reportEvaluationResult(NETWORK_VALIDATION_RESULT_INVALID,null /* redirectUrl */);transitionTo(mWaitingForNextProbeState);}}
}
