Unity Login Listener Not Call.

[Eser Telekom]

I am using c# client of smartfoxserver .
Smartfox server v.: 1.5.3.0
Unity v. : 4.5.5f1
Android min SDK : 2.3.3

and build to android from unity. When i try to login smartfox on android OS 4.3 (Tested : Galaxy Note 3), smartfox is going to exception and never callback to Listener.DDMS result is :

11-11 16:49:45.724: I/Unity(27043): Error handling data: Object reference not set to an instance of an object at Sfs2X.Entities.SFSRoom.SetVariables (ICollection`1 roomVariables) [0x00000] in <filename unknown>:0

What is problem ? Is it bug or how can i fix ?

[Lapo]

Hi,
can you test in the Unity Editor instead and tell me if the same error appears?
Also what is the version of SmartFoxServer 2X? You have posted the client version, but not the server.

Thanks

[Eser Telekom]

Smartfox Server v : 2.9.0
Smartfox Client v. : 1.5.3.0

No problem in Unity Editor and I tested 3 android devices :

1- Android 4.1 -> No problem
2 - Android 2.3.6 -> No problem
3 - Android 4.3 -> **Can not call Login Listener**

[Lapo]

Pretty strange problem. It should either work on any device or not work on any device.

One of the problems with debugging these sort of issues is that we have no idea how Unity compiles the C# code into a native application for the device.
According to this page:
http://docs.unity3d.com/Manual/android- ... rting.html

There seem to be a way to get more details about the problem. Have you tried it?

[Eser Telekom]

Yes.Unity support team said : It ' s about Smartfox.

[Lapo]

IMHO that doesn't sound like a very specific answer
Anyways,
if the code works in the Editor and on two other devices, and you are always connecting to the same server... you see that the only variable is the target device.

So, let's blame the device?
Can you confirm that in your testing scenario the only variable is the target device/OS?

Maybe there's something else you have also changed while testing? Maybe you're logging into different zones? (unlikely it makes any difference, but stil...)

Thanks

Hey Lapo,

I confirm that we get this exception in Galaxy Note 3. I did not change anything like zones while testing. I have tested with the same apk in all other devices.
Please note that this exception occurs when smartfox dll processes! So it seems something is wrong on smartfox side for logging in operation with Galaxy Note 3 somehow.

[Lapo]

yes, it's clear that it happens in the SFS2X dll, no doubt about that.

I'll be more specific about my doubts about the Unity --> Android exporter. Similar SFS2X runtime issues have been reported for iOS and it turns out that the way in which Unity translates C# code to native ARM code causes the runtime exception.

Similarly the developers could run the app a 1000 times in the Editor or WebPlayer and get no errors at all, but as soon as they exported and run on iOS the crashes appeared.

In any case there are differences between iOS and Android for what concerns Unity exports. Under the latter they use a .Net bytecode interpreter to run the game code (and libraries), so the C# code is not really transformed, there's just a different runtime.

All this is fine and dandy but it doesn't explain what might be going on. Since you're using the same APK you shouldn't get an error only by changing device/OS.
Additionally the reported error tells us very little about what is going on.

In order to be able to investigate this further we need a reliable way to reproduce the problem.

thanks

First of all i can send more debug datas , but how ?

I tested 100 times to login via Galaxy Note 3(android 4.3)
%24 it was login to smartfox and % 76 it was not login. -> This situation is Client Side.
Important thing : I checked server side then user was login all time.(%100 No problem in server side)

Client Side sometimes getting 490 byte of login Data (Exception is occur), sometimes 3500 byte of login Data (No exception )

Debug datas of Client Side :

If you want to send more debug data you can send us zipped files to our support@... email.
Also add a reference to this discussion.

You could turn on the SmartFox.debug and capture the debug output for both a device that always works and the Galaxy Notes.
At least we could compare them and see if there's anything that could provide a clue.

Thanks
