Google cloud storage don't work base on users

[khmereshop]

Hello

I just try to get my users to upload their voice recorder in mp3 file or image file to upload the file into my google cloud storage. Base on this example, it does not work base on user perspective.

1. a user click on upload browse button to upload file without asking any other question
2. it does not work if a user don't have cloud storage account
