i ve got this error , i realise that this error comes from the bitmap wich load the song cover bitmap
this is how i create the cover bitmap
B4X: 
If MP.Cover = Null Then
ImgCover.Visible = False
Else
            Dim In As InputStream
            In.InitializeFromBytesArray(MP.Cover,0,MP.Cover.Length)
            Dim bmp As Bitmap
            bmp.Initialize2(In)
            ImgCover.Bitmap = CreateScaledBitmap(bmp,ImgCover.Width,ImgCover.Height)
            ImgCover.Visible = True
            In.Close
           
End If

what is the best way to create the bitmap and maintain the memory happy? tnx

Dim out As OutputStream = File.OpenOutput(File.DirDefaultExternal,Main.pathimages&filename, False)
File.Copy2(job.GetInputStream, out)
out.Close '<------- very important
