Ionic Android Internal Shared Memory

Question

I'm using Ionic v1 with $cordovaFile and cordova email plugin to create a file and then attach it to a new email. I have a working solution for iOS on any device, but I've come across a weird issue with Android.

When attempting to attach a file created in any internal storage location on Android (dataDirectory, etc), I receive "permission denied for attachment". However, when I save the file to external storage, the attachment is successfully added.

I have published my application using external storage for Android, but unfortunately some of today's most popular devices don't have external storage.

Does anyone know a solution? I've considered workarounds, such as uploading the file to a file-hosting service, and including a download link in the email. I would use $cordovaFileTransfer, but I don't know if there would be permissions errors in internal storage. I'd like to use a true email attachment if possible. Thanks!

I think your issue is related to permission. I have implemented this for file attachment to give a permission for file attachment try it hope this help you. Try this plugin cordova.plugins.permissions

 function checkPermission() {
            var permissions = cordova.plugins.permissions;
            permissions.hasPermission(permissions.READ_EXTERNAL_STORAGE, checkPermissionCallback, null);
        }

function checkPermissionCallback(status) {
            $localStorage.StoragePermission = status.hasPermission;
            if (!status.hasPermission) {
                var permissions = cordova.plugins.permissions;
                permissions.requestPermission(permissions.READ_EXTERNAL_STORAGE, null, null);                
            }
        }
