Android权限仅在第二次运行时打开

Question

首次安装应用程序时，权限不会运行，但是当您关闭应用程序并再次打开时，权限将打开。

这是代码：

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            // only for gingerbread and newer versions

            Dexter.withActivity(getActivity())
                    .withPermissions(
                            Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE,
                            Manifest.permission.CAMERA, Manifest.permission.CALL_PHONE
                    )
                    .withListener(new MultiplePermissionsListener() {
                        @Override
                        public void onPermissionsChecked(MultiplePermissionsReport report) {
                            // check if all permissions are granted
                            if (report.areAllPermissionsGranted()) {
                                // do you work now

                            }

                            // check for permanent denial of any permission
                            if (report.isAnyPermissionPermanentlyDenied()) {
                                // permission is denied permenantly, navigate user to app settings
                            }
                        }

                        @Override
                        public void onPermissionRationaleShouldBeShown(List<PermissionRequest> permissions, PermissionToken token) {
                            token.continuePermissionRequest();
                        }
                    })
                    .onSameThread()
                    .check();
        }
