java.lang.IllegalStateException: RealRxPermission.onRequestPermissionsResult invoked but didn't find the corresponding permission request.

On some phones when requesting the WRITE_EXTERNAL_STORAGE permission i am getting:

Fatal Exception: java.lang.RuntimeException: Unable to resume activity {io.soulpicks.android.beta/com.vanniktech.rxpermission.ShadowActivity}: java.lang.RuntimeException: Failure delivering result ResultInfo{who=@android:requestPermissions:, request=42, result=-1, data=Intent { act=android.content.pm.action.REQUEST_PERMISSIONS (has extras) }} to activity {io.soulpicks.android.beta/com.vanniktech.rxpermission.ShadowActivity}: java.lang.IllegalStateException: RealRxPermission.onRequestPermissionsResult invoked but didn't find the corresponding permission request.

This is what I use to call it:

 permissionManager.request(WRITE_EXTERNAL_STORAGE)
                .subscribeOn(schedulerProvider.newThread())
                .observeOn(schedulerProvider.ui())
                .subscribeBy(onSuccess = {
                    permissionRequest.value = it
                },
                        onError = {
                            permissionRequest.value = Permission.denied(WRITE_EXTERNAL_STORAGE)
                        })
                .addTo(disposables)

Yep, fine with me! 🙌

using the ShadowActivity has its drawbacks.

I think it’s not even an issue of ShadowActivity vs. retained fragment. Using a cold Observable that triggers the permission request on subscribe and emits the result is, in my opinion, not the right abstraction. Permission results are a hot observable, since they can be emitted “before” the request.

It works for the request-in-onCreate case, but maybe the sample should be updated with that in mind.

Sure, I can have a look! Not sure when I’ll have time yet, hopefully soon.

Mind taking a crack at this?
