Just checked cordova-diagnostic-plugin@4 and the error still occures.

Seems that the Android APIs have changed since API 26, as stated here:

there's no way on Android API 26 to listen to implicit broadcasts like <action android:name="android.location.PROVIDERS_CHANGED" /> if the app is killed or isn't currently running in background.

Since the plugin currently uses implicit broadcast filters I'll need to rewrite it to register broadcast receivers at runtime. Thanks Google...

[iwan-uschka]

Thanks for taking care of this one. And yeah, thanks google...

Only now did I spot the Broadcast Limitations section in the Android 8.0 documentation.

Anyway, I'm working on this now so hope to push out a patch version some time today.

@dpa99c I have noticed an odd behaviour registerLocationStateChangeHandler() for Android across all devices in v5.0.0. We are using Ionic4 with [email protected].

1. The above page requires location permission and the modal is presented to the user. The app is listening to registerLocationStateChangeHandler() so that a map can be rendered in this page.

2. After allowing permission registerLocationStateChangeHandler() dosent seem to have fired so we still have the open setting button.

3. Opening Setting and allowing location.

4. Relaunching the application after the settings change works fine.

I tried to debug this. It seems registerLocationStateChangeHandler() dosent receive any state change when allowing permission from the modal popup but it receives state change when allowing it from settings.

Sorry if this is the wrong place to mention this issue. It looked like it had to do with registerLocationStateChangeHandler().

@EdwinRozario I do have the same problem now with android devices, did you find a solution for it?
