[kenilt]

I have got crash error when I trying to request permission. Which below:

Caused by: 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 {com.feelsfashionltd.feels.debug/com.karumi.dexter.DexterActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.Context android.view.ViewGroup.getContext()' on a null object reference at android.app.ActivityThread.deliverResults(ActivityThread.java:3988) at android.app.ActivityThread.performResumeActivity(ActivityThread.java:3301) at android.app.ActivityThread.handleResumeActivity(ActivityThread.java:3359)  at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2549)  at android.app.ActivityThread.access$900(ActivityThread.java:150)  at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1394)  at android.os.Handler.dispatchMessage(Handler.java:102)  at android.os.Looper.loop(Looper.java:168)  at android.app.ActivityThread.main(ActivityThread.java:5845)  at java.lang.reflect.Method.invoke(Native Method)  at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:797)  at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:687)  Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.Context android.view.ViewGroup.getContext()' on a null object reference at android.support.design.widget.Snackbar.<init>(Snackbar.java:180) at android.support.design.widget.Snackbar.make(Snackbar.java:209) at com.karumi.dexter.listener.multi.SnackbarOnAnyDeniedMultiplePermissionsListener.showSnackbar(SnackbarOnAnyDeniedMultiplePermissionsListener.java:63) at com.karumi.dexter.listener.multi.SnackbarOnAnyDeniedMultiplePermissionsListener.onPermissionsChecked(SnackbarOnAnyDeniedMultiplePermissionsListener.java:58) at com.karumi.dexter.listener.multi.CompositeMultiplePermissionsListener.onPermissionsChecked(CompositeMultiplePermissionsListener.java:54) at com.karumi.dexter.MultiplePermissionListenerThreadDecorator$1.run(MultiplePermissionListenerThreadDecorator.java:45) at com.karumi.dexter.MainThread.execute(MainThread.java:32) at com.karumi.dexter.MultiplePermissionListenerThreadDecorator.onPermissionsChecked(MultiplePermissionListenerThreadDecorator.java:43) at com.karumi.dexter.DexterInstance.onPermissionsChecked(DexterInstance.java:264) at com.karumi.dexter.DexterInstance.updatePermissionsAsDenied(DexterInstance.java:247) at com.karumi.dexter.DexterInstance.onPermissionRequestDenied(DexterInstance.java:148) at com.karumi.dexter.Dexter.onPermissionsRequested(Dexter.java:176) at com.karumi.dexter.DexterActivity.onRequestPermissionsResult(DexterActivity.java:54) at android.app.Activity.dispatchRequestPermissionsResult(Activity.java:6564) at android.app.Activity.dispatchActivityResult(Activity.java:6443) at android.app.ActivityThread.deliverResults(ActivityThread.java:3984) at android.app.ActivityThread.performResumeActivity(ActivityThread.java:3301)  at android.app.ActivityThread.handleResumeActivity(ActivityThread.java:3359)  at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2549)  at android.app.ActivityThread.access$900(ActivityThread.java:150)  at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1394)  at android.os.Handler.dispatchMessage(Handler.java:102)  at android.os.Looper.loop(Looper.java:168)  at android.app.ActivityThread.main(ActivityThread.java:5845)  at java.lang.reflect.Method.invoke(Native Method)  at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:797)  at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:687) 

Can you check this error and improve it?

Steps to reproduce

First I request Storage permission -> choose allow
Then I request Camera, Record Audio and Storage permission -> Deny all -> Crash

Version of the library

Hi @kenilt

Just a guess but I'm seeing you are using the utility SnackbarOnAnyDeniedMultiplePermissionsListener class. Have you initialized its rootView with a null value? To correctly show the snackbar you need to specify what will be its parent view to successfully attach itself to it.

You have an example of how to use this class in the provided sample project included in this repository, SampleActivity.java:148

Let us know if the issue persists.
Thanks for reporting!

@Serchinastico You are right. I have initialized SnackbarOnAnyDeniedMultiplePermissionsListener with a ViewGroup that have not attached to its parent successfully. I have solved it by using

view.post(new Runnable() {
        @Override
        public void run() {
            // init SnackbarOnAnyDeniedMultiplePermissionsListener here
        }
    });

Thank you!
