rmartin94 opened a new issue #99: Network status not reliable URL: https://github.com/apache/cordova-plugin-network-information/issues/99 # Bug Report ## Problem ### What is expected to happen? I would expect this plugin always to reflect the true network status of a mobile device, being notified when the status changes with its proper value ### What does actually happen? In general it works fine, but at some point I get stuck with a notification indicating that there's no network connection while the mobile device actual does have a connection. It's hard to reproduce, most time it works fine but on some occasions it doesn't. I subscribe to both onConnect and onDisconnect events. This provides a really bad user experience since there are many web services that are not being called depending on the network status (some others are cached locally since I try to provide offline support and then sync to the server when connection is back online), like the login web service. I'm not sure if I should rely entirely on this plugin anymore or if I'm doing something wrong. Does anyone had this behavior? I've seen it mostly on Android devices. ## Information <!-- Include all relevant information that might help understand and reproduce the problem --> I subscribe to the provided events by the plugin on a service I use across the application, and when they are fired I check the network type just in case.... but to double check I set a timeout of 2 seconds and then re-check the current network type. Only then I change the status based on the type. If by some reason a subsequent event is fired I clear the timeout to prevent this with messing with the current network status from the last fired event ### Command or Code <!-- What command or code is needed to reproduce the problem? --> ``` public online: boolean; private notify; constructor(private _pf: Platform, private _nw: Network) { this.initNetwork(); } public initNetwork(){ this._pf.ready().then(() => { if (this._pf.is('cordova')) { this._nw.onDisconnect().subscribe(() => { console.log('now type... ', this._nw.type); this.clearNetworkNotification(); this.notify = setTimeout(() => { console.log('just to be sure.. ', this._nw.type); if (this._nw.type.toLowerCase() === 'none') { console.log('we are offline!'); this.online = false; } }, 2000); }); this._nw.onConnect().subscribe(() => { console.log('now type... ', this._nw.type); this.clearNetworkNotification(); this.notify = setTimeout(() => { console.log('just to be sure.. ', this._nw.type); if (this._nw.type.toLowerCase() !== 'none') { console.log('we are online!'); this.online = true; } }, 2000); }); } }); } private clearNetworkNotification() { if (this.notify) { clearTimeout(this.notify); this.notify = undefined; } } public getNetworkStatus(){ return this.online; } ``` ### Environment, Platform, Device <!-- In what environment, on what platform or on which device are you experiencing the issue? --> I'm building an Ionic 4 application in Angular 7 with cordova ### Version information <!-- What are relevant versions you are using?
