We can't have multiple constructPermissionsRequest within the same fragment

[SamYStudiO]

Hello,

I have 2 constructPermissionsRequest (one for location and one for external storage) from the same fragment (i don't make them using the same construct because i want to call them in the right context and so they need to be call at different time).

Problem is the second one will never gets its callbacks called once the first one has been accepted.
this is because when you call PermissionsRequesterImpl.launch ALL observers are removed.

PermissionsDispatcher/ktx/src/main/java/permissions/dispatcher/ktx/PermissionsRequesterImpl.kt

Line 38 in d7ac8bf

viewModel.removeObservers(activity)

Here is a user case >

• you construct 2 permissions
• you click a button which call the first permission and accept it, everything is fine so far
• you click again that button PermissionsRequesterImpl detect it is accepted and remove observers
• you click a second button to call 2 permissions and this time you never get notified beacause there is no more observers

Solution would be to have a unique observer for each PermissionsRequesterImpl

Environment

• core 4.9.1
• ktx 1.1.3

maybe dont need removeObservers?

PermissionsRequesterImpl

ViewModelProvider(activity).get(PermissionRequestViewModel::class.java).observe

owner is not good

Fragment.constructPermissionsRequest

owner is Fragment better use not actiity
and
i hope PermissionsRequester add function clear(inner call removeObservers)

Currently, if you implement call with multiple Fragments,
it may refer to a Fragment that has already been destroyed, resulting in a crash.
