Android issue - resolveDirectoryUrl FileError {code: 1, message: "NOT_FOUND_ERR"}

[josuej3834]

I have used ionic3-image-cache for cache image from firebase database.
But there is an issue when run the app on android, it gives me some errors.

• resolveDirectoryUrl FileError
• Create directory fail FileError {code: 12, message: "PATH_EXISTS_ERR"}

I have used diagnostic plugin for the permission of external storage like this.
this.diagnostic.requestExternalStorageAuthorization().then(() => {
//User gave permission
}).catch(error => {
//Handle error
});

but still same error,
If someone has the issue like this, please help me.
Thanks.
