Subject [jira] [Commented] (CB-12035) [cordova-plugin-network-information] connection info is not reliable on Android 6
Date Tue, 06 Nov 2018 14:51:00 GMT


ASF GitHub Bot commented on CB-12035:

terpro commented on issue #74: [WIP] CB-12035 (android) Fix bug [cordova-plugin-network-information]
connection info is not reliable on Android 6
   @PieterVanPoyer The changes you made originally fixed the issue for Android 6+ devices,
but broke anything below 6. Is it possible to just add an API level/Android version check
and use the old or new code based on that?

> I've noticed that information exposed by the plugin is not reliable. It happens often
that I'm connected to the internet via WiFi, and the plugin says that there's no connection.
> It's not easy to reproduce it on-demand, but I reproduced it many times recently. It
happens most often when in the morning, I open the Cordova app that was running in background
throughout the night.
> Then, when I connect to Chrome Dev Tools, I can do a repl session like this:
> {code}
> > navigator.connection.type
> "none"
> > window.fetch('').then(function(res) {console.log(res.status)})
> Promise {[[PromiseStatus]]: "pending", [[PromiseValue]]: undefined}
> 200
> Fetch complete: GET "".(anonymous function)
> > navigator.connection.type
> "none"
> {code}
> So, the plugin thinks I'm offline, yet any HTTP calls done within the app without checking
if I'm offline or online, are successful (either from the app or devtools).
> When I disable WiFi and reenable it, after a few seconds the plugin updates its state
and then it tells that connection type is "wifi".
> There are several possibilities here:
> - either system (or device driver) gives us incorrect information, or
> - cordova plugin is caching data and/or not listening properly to all the events and/or
incorrectly processing it
> and most probably the issue manifests itself when the device is asleep for many hours
(but I'm not sure about this).
> Note that I also noticed another issue, that sometimes the Chrome network stack thinks
I'm offline (when I do an HTTP call, it fails immediately and I see network errors in devtools
console) - and then I restart the Cordova app, and everything's fine, all HTTP calls are ok
- but this is unrelated to this ticket, and perhaps a bug in Chrome.
> This ticket seems to be most likely a bug in the plugin, because as I said before, doing
HTTP call succeeds despite the plugin telling me that I'm offline.
