Uploading files in Android and IOS

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.

Code (csharp):

1.  
2. WWW localFile = new WWW("file:///" + localFileName);
3.  yield return localFile;
4.   if (localFile.error == null)
5.             Debug.Log("Loaded file successfully");
6.     else
7.         {
8.             Debug.Log("Open file error: "+localFile.error);
9.             yield break; // stop the coroutine here
10.         }
11.  

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.

 

Bump!

 

hi , did you solved the issue ? im having same issue here

 

Same problem here :/ I can't send large files on android.

Code (CSharp):

1. E/dalvikvm-heap(19330): Out of memory on a 23393512-byte allocation.
2. I/dalvikvm(19330): "Thread-1299" prio=5 tid=21 RUNNABLE
3. I/dalvikvm(19330):   | group="main" sCount=0 dsCount=0 obj=0x42f4b640 self=0x789ccb48
4. I/dalvikvm(19330):   | sysTid=20271 nice=0 sched=0/0 cgrp=apps handle=2106730800
5. I/dalvikvm(19330):   | state=R schedstat=( 131573429 29466518 173 ) utm=7 stm=6 core=2

8. I/dalvikvm(19330):   at com.android.okhttp.internal.http.RetryableOutputStream.write(RetryableOutputStream.java:64)
9. I/dalvikvm(19330):   at com.unity3d.player.WWW.runSafe((null):-1)
10. I/dalvikvm(19330):   at com.unity3d.player.WWW.run((null):-1)

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.
