Permissionsdispatcher: Lint showing "Useless @OnShowRationale declaration"

[silverAndroid]

---

Overview

• Describe the issue briefly

I updated the library to 3.0.1 from 2.4.0 and now I'm seeing a Lint error saying "Useless @OnShowRationale declaration". It's not stopping me from compiling my code but I'm wondering why it's showing up because when I remove it, the function is no longer being used. Maybe it's because I'm checking for 2 permissions in the same Fragment?

Expected

• What is the expected behavior?

I guess not for it to show up since it doesn't seem to be useless.

Actual

• What is the actual behavior?

Environment

• Which library version are you using?

3.0.1

• On which devices do you observe the issue?
• Note any other information that might be useful

Reproducible steps

• While it's not required, it'd be perfect to add a link to a sample project where you encounter the issue

It's happening in this class

@silverAndroid Sorry for the late. It's kinda weird so let us investigate 🙇

I see it too.
It's only show in Fragment in my project.

I have this problem:

@OnShowRationale(Manifest.permission.ACCESS_FINE_LOCATION)
void showRationaleForLocationPermission(PermissionRequest request) { }

@NeedsPermission(Manifest.permission.ACCESS_FINE_LOCATION)
void getLocationPermissionAndLaunchMarket() { }

I see this same warning for useless OnShowRationale. Using 3.1.0

@imminent, I was able to avoid the warning by swapping the order which those methods are declared.
