问题 Is there a way to access Android's broadcast that the WiFi connection is currently a captive portal (requires web login)? Android seems to do have this built in. If not a broadcast receiver, is there a way to check for the result of the captive portal check? I believe it's using this class, which is hidden from the API: http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/5.L_preview/android/net/CaptivePortalTracker.java Prior to 4.2, it was probably using:
