Android Studio -Firebase Storage Exception " Object does not exist at location." solve

In this days I solve this Exception hope this will help you all.
this exception occurs when we try to store images in firebase storage.
the main problem is the bucket folder. Actually, Firebase object cannot find the location so it shows this error.

here is my solution for this.
(if you have many images with the same name then you have to add random name generator )

I think this will help some of you thank you
