PermissionsManager.getInstance().requestPermissionsIfNecessaryForResult is not working properly

I am trying to do:

PermissionsManager.getInstance().requestPermissionsIfNecessaryForResult(getActivity(),
                            new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, new PermissionsResultAction() {

                                @Override
                                public void onGranted() {
                                    Intent taskPicturesStarter = new Intent(getActivity(), TaskPicturesActivity.class);
                                    taskPicturesStarter.putExtra(ActivityHelper.KEY_TASK_MODEL, mTaskModel);
                                    startActivityForResult(taskPicturesStarter, DATE_TIME_PICKER_ACTIVITY_CODE);
                                }

                                @Override
                                public void onDenied(String permission) {
                                    Toast.makeText(getActivity(),
                                            "Sorry, we need the Storage Permission to do that",
                                            Toast.LENGTH_SHORT).show();
                                }
                            });

But onGranted or onDenied method are not executing.

In the fragment i have also included:

@Override
    public void onRequestPermissionsResult(int requestCode,
                                           @NonNull String[] permissions,
                                           @NonNull int[] grantResults) {
        PermissionsManager.getInstance().notifyPermissionsChange(permissions, grantResults);
    }

I have also tried reinstalling the app but still same problem.

@Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { PermissionsManager.getInstance().notifyPermissionsChange(permissions, grantResults); } I use this code ,and onGranted/onDenied can be called in my Activity.

需要在每一个请求权限（单个或所有）的地方都重写下面这个方法，才可以正确回调。 @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { PermissionsManager.getInstance().notifyPermissionsChange(permissions, grantResults); }
