Wandrille RONCE commented on CB-12035: -------------------------------------- Same issue with Android 7.0 and Samsung Galaxy S8+. The problem occure only with Wifi. Sometimes, navigator.connection.type== none, even if Wifi is working well. > [cordova-plugin-network-information] connection info is not reliable on > Android 6 > --------------------------------------------------------------------------------- > > Key: CB-12035 > URL: https://issues.apache.org/jira/browse/CB-12035 > Project: Apache Cordova > Issue Type: Bug > Components: cordova-plugin-network-information > Affects Versions: 1.3.0 > Environment: Samsung Galaxy Edge S6 / Android 6 > useragent: "Mozilla/5.0 (Linux; Android 6.0.1; SM-G925F Build/MMB29K; wv) > AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/53.0.2785.124 > Mobile Safari/537.36" > reproduced with: > cordova-plugin-network-information@1.3.0 (latest) > cordova-plugin-network-information@1.2.0 > Reporter: jakub-g > Labels: android > > 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('http://www.example.org').then(function(res) > > {console.log(res.status)}) > Promise {[[PromiseStatus]]: "pending", [[PromiseValue]]: undefined} > 200 > Fetch complete: GET "http://www.example.org/".(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. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@cordova.apache.org For additional commands, e-mail: issues-h...@cordova.apache.org
