This is a very simple tutorial on how to use the storage file options.
Upload File
Uploads a file to an existing bucket.
B4X:
Dim UploadFile As Supabase_StorageFile = xSupabase.Storage.UploadFile("Avatar","test.png")
UploadFile.FileBody(xSupabase.Storage.ConvertFile2Binary(File.DirAssets,"test.jpg"))
Wait For (UploadFile.Execute) Complete (StorageFile As SupabaseStorageFile)
If StorageFile.Error.Success Then
Log($"File ${"test.jpg"} successfully uploaded "$)
Else
Log("Error: " & StorageFile.Error.ErrorMessage)
End IfDownloads a file.
B4X:
Dim DownloadFile As Supabase_StorageFile = xSupabase.Storage.DownloadFile("Avatar","test.png")
Wait For (DownloadFile.Execute) Complete (StorageFile As SupabaseStorageFile)
If StorageFile.Error.Success Then
Log($"File ${"test.jpg"} successfully downloaded "$)
ImageView1.SetBitmap(xSupabase.Storage.BytesToImage(StorageFile.FileBody))
Else
Log("Error: " & StorageFile.Error.ErrorMessage)
End IfReplaces an existing file at the specified path with a new one.
B4X:
Dim UpdateFile As Supabase_StorageFile = xSupabase.Storage.UpdateFile("Avatar","test.png")
UpdateFile.FileBody(xSupabase.Storage.ConvertFile2Binary(File.DirAssets,"test2.jpg"))
Wait For (UpdateFile.Execute) Complete (StorageFile As SupabaseStorageFile)
If StorageFile.Error.Success Then
Log($"File ${"test.jpg"} successfully updated "$)
Else
Log("Error: " & StorageFile.Error.ErrorMessage)

Moves an existing file to a new path in the same bucket.
FromPath - The original file path, including the current file name. For example `folder/image.png`
ToPath - The new file path, including the new file name. For example `folder/image-copy.png`
B4X:
Wait For (xSupabase.Storage.MoveFile("Avatar","public/avatar1.png", "private/avatar2.png").Execute) Complete (StorageFile As SupabaseStorageFile)
If StorageFile.Error.Success Then
Log($"Files successfully moved "$)
Else
Log("Error: " & StorageFile.Error.ErrorMessage)
End IfCopies an existing file to a new path in the same bucket.
FromPath - The original file path, including the current file name. For example `folder/image.png`
ToPath - The new file path, including the new file name. For example `folder/image-copy.png`
B4X:
Wait For (xSupabase.Storage.CopyFile("Avatar","public/avatar1.png", "private/avatar2.png").Execute) Complete (StorageFile As SupabaseStorageFile)
If StorageFile.Error.Success Then
Log($"Files successfully copied "$)
Else
Log("Error: " & StorageFile.Error.ErrorMessage)
End IfRetrieve public URL
A simple convenience function to get the URL for an asset in a public bucket. If you do not want to use this function, you can construct the public URL by concatenating the bucket URL with the path to the asset.
This function does not verify if the bucket is public. If a public URL is created for a bucket which is not public, you will not be able to download the asset.
B4X:
Log(xSupabase.Storage.GetPublicUrl("Avatar","test.png"))Create signed url to download file without requiring permissions. This URL can be valid for a set number of seconds.
B4X:
Wait For (xSupabase.Storage.CreateSignedUrl("Avatar","test.png",60).Execute) Complete (StorageFile As SupabaseStorageFile)
If StorageFile.Error.Success Then
Log(StorageFile.SignedURL)
Dim DownloadFile As Supabase_StorageFile = xSupabase.Storage.DownloadFile("Avatar")
DownloadFile.Path("test.png")
DownloadFile.SignedURL(StorageFile.SignedURL)
Wait For (DownloadFile.Execute) Complete (StorageFile As SupabaseStorageFile)
If StorageFile.Error.Success Then
Log($"File from signed URL successfully downloaded "$)
ImageView1.SetBitmap(xSupabase.Storage.BytesToImage(StorageFile.FileBody))
Else
Log("Error: " & StorageFile.Error.ErrorMessage)
End If
Else
Log("Error: " & StorageFile.Error.ErrorMessage)
End If
