Angular-file-upload only select single file with multiple set in the platform andriod

I use component angular-file-upload in html in the inoic project, I may select multiple file in the browser on PC platform like Mac OS or windowds7, but I only select single file in my andriod moble phone…
What’s happened about this case?

as far as I know, android webview doesn’t support multiple file upload for that we have to build cordova plugin
