Firebase Storage “retrieves a long lived download URL” using getDownloadUrl() now deprecated

问题

This getDownloadUrl() method showed deprecated after updating to

'com.google.firebase:firebase-storage:15.0.2'

Nothing on the official site to another way to achieve the url, So there's any way to achieve the Url in non deprecated way?

/** @deprecated */
@Deprecated
@Nullable
public Uri getDownloadUrl() {
    StorageMetadata var1;
    return (var1 = this.getMetadata()) != null ? var1.getDownloadUrl() : null;
    }
}

回答1:

In the docs it says this:

The getDownloadUrl() and getDownloadUrls() methods of the StorageMetadata class are now deprecated. Use getDownloadUrl() from StorageReference instead.

So you need to use getDownloadUrl() that is inside the StorageReference

public Task<Uri> getDownloadUrl ()

Asynchronously retrieves a long lived download URL with a revokable token. This can be used to share the file with others, but can be revoked by a developer in the Firebase Console if desired.
