trying to add marshmallow permissions using "Permissions Dispatcher"

Question

I'm trying to use the plugin Permissions Dispatcher(https://github.com/hotchemi/PermissionsDispatcher) to handle Marshmallow runtime permissions in a GPSTracker class which I want to call in a fragment, but I'm still getting the error "Call requires permission that may be rejected by user: Code should explicitly check to see if permission is available..." I think I need to add something to MainActivity but I can't figure out what.

GPSTracker.java

I'm a developer of PermissionsDispatcher. It seems you don't follow the usage of the library. I recommend to look at sample code. You have to use generated class by annotation processing. https://github.com/hotchemi/PermissionsDispatcher/tree/master/sample

hey Shintaro nice Library but please help us by providing code for location permissions ACCESS_FINE_LOCATION. We are facing a lot of problem in doing this. – Manav Patadia Mar 20 '16 at 07:48
There is nothing special. Could u check below code? https://github.com/konifar/droidkaigi2016/blob/a92ae2dc943e97243d9eea5b00f66382e8fc86e9/app/src/main/java/io/github/droidkaigi/confsched/fragment/MapFragment.java#L115 – Shintaro Katafuchi Mar 21 '16 at 17:39
@ShintaroKatafuchi I am trying to add ACCESS_BACKGROUND_LOCATION and ACCESS_COARSE_LOCATION for support background scanning on Android 10 devices but it's not working. How could I add these both permission on my method where I start background location scanning?I think there is no way to add more than one permission on single method but how could I achieve this? Currently it's just showing two options and not all three with "Always allow". You help is appreciated. – Prashant.J Apr 16 '20 at 06:32
