Issue
This picture is of the upload fragment made by me using android studio and when the list item is been clicked the object should be downloaded.It's Working fine and the object is been downloaded on my phone and the other phone on which I installed it. But when I shared this application to others it gives the error marked in the picture on their phones.Updating the play services is not removing the error.
Solution
After 2 days of frustration, I found out that there is a bug in firebase storage.Thus, you've to simply turn off and on your storage manually,thanks.
