Context

Using the background geolocation provider to track individual users, on Android Oreo

Expected Behavior

On each call, my code runs

Actual Behavior

Crashes the App

Possible Fix

It appears the issue is to do specifically with Android Orea (SDK 27) as during debugging in Android Studio it is throwing:

android.app.RemoteServiceException: Bad notification for startForeground: java.lang.RuntimeException: invalid channel for service notification: Notification(channel=null pri=0 contentView=null vibrate=null sound=null defaults=0x0 flags=0x62 color=0x00000000 vis=PRIVATE)

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:807)

which is attached to https://stackoverflow.com/questions/47531742/startforeground-fail-after-upgrade-to-android-8-1 (albeit it is noted the code snippets are Kotlin and not java, though the principle is the same).

Steps to Reproduce

1. Run basic example on Android 8.1

FYI Oreo support has been added in 3.x branch.

@mauron85
When I add the 3.x.x branch, reinstalling the plugin and updating everything I’ve got the message:

console.warn: Native: tried calling BackgroundGeolocation.configure, but the BackgroundGeolocation plugin is
[app-scripts]             not installed.
[app-scripts] [18:53:21]  console.warn: Install the BackgroundGeolocation plugin: 'ionic cordova plugin add
