Unable to create service io.flutter.plugins.geofencing.GeofencingService

[jawand]

I added this plugin into my project and when I click the Register button to add a GeoFence it throws this exception.

I am running this on Emulator Pixel 2 API 27. But I get the same error on a real device with Noguet 7.1.

Location is Mode is on High Accuracy and wifi and mobile data are enabled.

This is my AndroidManifest.xml

Any help is appreciated.

It looks like you're using another plugin that requires the presence of an Activity on Android and is trying to access it while it's being initialized. This won't work when there's no UI and the app is executing in the background, so you'll need to manually make sure that plugin doesn't get registered. Unfortunately this is a general issue with all background enabled plugins, not just this one.

for me it was keyboard_visibility 0.5.2, maybe it helps....

I have the same issue, the plugin have to manage this: https://github.com/transistorsoft/flutter_background_fetch/blob/master/android/src/main/java/com/transistorsoft/flutter/backgroundfetch/BackgroundFetchPlugin.java#L46
