We are developing an Android Application (Java) that reads an image, encode the bytes in base64 to send them over HTTP (via GET) to a WebService written in VB.NET.On .NET side, they are using this :
Dim Pix As Image
Pix = Image.FromFile("C:UsersPublicPicturesSample PicturesTree.jpg")
Dim ms As New MemoryStream[code]....
How can I pass the correct string to them to correctly decode the image from Java encoding (unsigned) to .NET decoding (signed)?
