Android Question [Solved] RuntimePermissions.CheckAndRequest NullPointerException: Attempt to invoke virtual method WeakReference.get

[weighment]

This is a Default app with the code below in starter service called from a button click in Main, error is on line 7

B4A 12.20

side note: BLEExample project works on same device doing rp.check in B4XMainPage, but I saw that you generally need to use rp.check in a service. (new project has same error doing rp.check in Main or in a class or in starter service)

Sub checkPermissions

    Private rp As RuntimePermissions
    Dim phone As Phone
    Log(phone.SdkVersion) ' shows 29

    rp.CheckAndRequest(rp.PERMISSION_ACCESS_FINE_LOCATION)
    'Wait For B4XPage_PermissionResult (Permission As String, Result As Boolean)
    Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
    If Result = False Then
        ToastMessageShow("No permission: " & Permission, True)
        Return
    End If
    Return
    
End Sub

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: https://www.b4x.com/forum/showthread.php?p=78136
AddManifestText(

SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")

[Solved]
Just saw where rp.CheckAndRequest can only be called from an Activity. (though rp.Check can be called from a service)
Should have been obvious (...AndRequest)
Sorry for the distraction, feel free to delete
