MultiplePermissionsListener REQUEST_ONGOING

[andro-jedi]

Expected behaviour

Call onPermissionsChecked with already granted permissions

Actual behaviour

when I ask for permissions it call onError(DexterError error) with REQUEST_ONGOING error
Activity was closed and opened several times using startActivityForResult setResult(OK) or CANCEL before this happened.

Steps to reproduce

 Dexter.withActivity(getActivity())
                .withPermissions(
                        Manifest.permission.CAMERA,
                        Manifest.permission.READ_EXTERNAL_STORAGE
                ).withListener(new MultiplePermissionsListener() {
            @Override
            public void onPermissionsChecked(MultiplePermissionsReport report) {
                if (report.areAllPermissionsGranted()) {
                    openCamera();
                } else {
                    requestMultiplePermissions();
                 }
                   }

            @Override
            public void onPermissionRationaleShouldBeShown(List<PermissionRequest> permissions, PermissionToken token) {
                token.continuePermissionRequest();
            }
        }).withErrorListener(new PermissionRequestErrorListener() {
            @Override
            public void onError(DexterError error) {
                int y = 0; 
            }
        }).check();

Version of the library

3.0.0

Hi @PingForward

I'm wondering, are you following the README section about screen rotations? When the requesting activity dies due to a rotation or any other reason, we have to rebind the permission listeners by calling continueRequestingPendingPermissions instead of asking for those permissions again.

Got to say though that you are not the first person having this issue so we will probably need to do a smarter checking when requesting the same permissions more than once.

Hope that link helps, let us know if you still have problems with the library.

Hi, I also have this issue with PermissionListener. My activity open and close normally, without any rotation or other reason to kill the activity unexpectly, several times later, this exception happens.

Version is 3.0.0

[andro-jedi]

@Serchinastico No rotation, regular open close.

I can confirm. Also happens with PermissionListener (not Multiple* that is). Can't reproduce consistently, but most of the times when I start a permission request and deny it and then close the app (back-button, not simple pause/resume) and come back, it says REQUEST_ONGOING. Tested with/without rationale dialog and with/without continueRequestingPendingPermissions. It only seems to start working again once I kill the app process entirely.

The reason is when we create Dexter instance, the Context in DexterInstance become null.
I have sent a pull request.

We've got the same bug. Please, review this pull request.

Fixed in the PR #108. We are about to publish a new version :) Thanks everyone for your help!

Hi guys!
This problem can still be encountered in version 4.1.0.

[pedrovgs]

@ovitrif we can't reproduce it. Could you create a sample project public on github with the code needed to reproduce it?

[ovitrif]

@pedrovgs
Unfortunately not, it is for a complete application that it happens.

I can give a few details.
I'm using the multiplePermissions listener, using dagger, so I initialize dexter in the module.
The app has language changing capabilities, and the bug was usually seen in that case.
It failed when trying to get information about location permissions.
Basically, we had a screen which asks for GPS coordinates to order a list of items based on their distance to the user.
It was very difficult to reproduce the bug, but it seemed to appear randomly and the testers (not surprisingly) saw it quite often.
I was able one time to reproduce the issue, and had the debugger attached. Not sure if it was the REQUEST_ONGOING issue, but the code did stop at doing the .check() method.
No breakpoint was hit afterwards, and I had breakpoints in both methods of the multiple permissions listener.

In the end I fixed the issue by adding an error listener, where I run the code to check the permissions manually using Android code.

Having discussed this with my colleague, we wanted initially to check the permissions manually first, and only when they are not granted would we use Dexter.

I wonder why you guys stop in case of REQUEST_ONGOING always.
I can't say I know the code very well, but so far I didn't think of an error when doing it manually.

The problem with your approach, I think, is that you do all the complex code to ensure the user is asked to grant permissions.
But most of the time, the app will have the permissions granted, and by doing things the way they are now done in dexter, is like letting a door open for errors.
Could the logic be switched around, and check permissions first, if ok just go on?

Otherwise I find dexter unreliable, since I'll always have to wrap it with my own implementation for checking permissions.

I'm not sure it is intended to be used like that, but I would find it very useful if it was always reliable and you could just do the normal check for permissions before, for example, trying to get the user location.

Guys! same problem in version 5 also. How to fix once we get this
