Uploading files in Android and IOS

Target Platforms Mobile
1

Hi,

I’m developing an app for IOS and Android which uploading files to a server through HTTP(post/put). For images, the WWW/WWWform class works well, same for videos which are quite small < 50 mb. But for larger files >50~mb i get “out of memory”- exception.

This is because when the app read the file it stores it in the RAM until it’s uploaded.

WWW localFile = new WWW("file:///" + localFileName);
 yield return localFile;
  if (localFile.error == null)
            Debug.Log("Loaded file successfully");
	else
        {
            Debug.Log("Open file error: "+localFile.error);
            yield break; // stop the coroutine here
        }

Is there any way to chunk the data or is it possible to stream it through HTTP?

I have the possibility to upload through FTP aswell, but as far as I have understand the FTP support is limited in Unity3d.

Is there a way to fix this without native extensions?

Ok, I’m using WebClient now and it works great, I can upload 100mb+ files without any problems.
