Edit: see this comment on why the approach in this answer doesn't work:

firebaser here This answer is wrong. While it at first may appear to work (since it compiles) the result of getDownloadUrl().toString() is not a download URL, but a string representation of a Task object. For a better answer, see stackoverflow.com/a/55503926 or the sample in the Firebase documentation.

Original answer below...


In Firebase Storage API version 16.0.1, the getDownloadUrl() method using taskSnapshot object has changed. now you can use,

taskSnapshot.getMetadata().getReference().getDownloadUrl().toString()

to get download url from the firebase storage.
