i’m using the plugin Background-Geolocation https://github.com/mauron85/cordova-plugin-background-geolocation, https://ionicframework.com/docs/native/background-geolocation,
it worked correctly, but in operating systems android version 9 no, when using the app with android 9 devices the app is closed and indicates the following error “invalid channel for service notification startForeground”
how can I solve that?
I need help urgently please 
I have the same problem, and i solved on this way:
-
Remove
@ionic-native/background-geolocation -
Install this version
"cordova-plugin-mauron85-background-geolocation": "^3.0.1". -
Remove background imports
-
Remove declaration on constructor
-
Add
declare var window; -
Add variable
backgroundGeolocation: any; -
On constructor add this:
this.platform.ready().then(() => { this.backgroundGeolocation = (<any>window).BackgroundGeolocation; }); -
And to watch coords changes:
this.backgroundGeolocation.configure({yourConfig})
this.backgroundGeolocation.on('location', (location) => {}, (err)=>{})
I hope this solve your problem to.

This happen becauseyou are using an old version of this “mauron” plugin. you should use
“@mauron85/cordova-plugin-background-geolocation”: “^3.1.0”,
