Android Question Unable to Download a File using Firebase Storage

[beelze69]

Hi,

I am using Firebase Storage to download a file from Firebase Console.

I modified the example FirebaseStorageExample provided by Erel on link

https://www.b4x.com/android/forum/threads/firebasestorage-simple-file-storage-backend.68350/

Suitably.

My aim: To download a file sampleFBFile.jpg in the public folder under Firebase Storage to my
Dir.InternalCache.


The Rules in the Firebase Storage console is

service firebase.storage {
match /b/beelzetestproject.appspot.com/o {
match /{allPaths=**} {
allow read;
allow write: if request.auth != null;}


I have downloaded the constructed google-services.json file in mobile application folder.

The application compiles properly.

But when I run the example I get the message 'Unfortunately B4A.example has stopped'.

The log dump is :

<LOG DUMP>
connection failed.

The supplied bucketname does not match the storage bucket of the current instance.

beelzetestproject.appspot.com

So you are using gs://beelzetestproject.appspot.com while initializing the storage?

My code:

Where is the starter code for the Storage?

Hi !

My starter page is as below:

Sub Process_Globals
    Public auth As FirebaseAuth
    Public storage As FirebaseStorage
    Private bucket As String = "gs://beelzetestproject.appspot.com"
End Sub

Sub Service_Create
    auth.Initialize("auth")
    storage.Initialize("storage", bucket)
End Sub

Private Sub Auth_SignedIn (User As FirebaseUser)
    Log($"Signed in: ${User}"$)
    CallSub(Main, "SignedIn")
End Sub


Sub Service_Start (StartingIntent As Intent)

End Sub

Sub Application_Error (Error As Exception, StackTrace As String) As Boolean
    Return True
End Sub

Sub Service_Destroy

End Sub

Can you upload the project?
