    Hi,

    This is my very very first attempt on Unity with Android - so I'm uncertain if I do something stupidly wrong or if this is a real bugger.

    The issue I run into is, that I attempt to call a server via WWW class that is (knowingly) now responding on a port. I get a Connection refused (as expected) - but instead of continuing running the game, the build simply crashes.

    If I change the port, so that its actually connecting to a live host (but still a resource that doesnt exist) I get a FileNotFound - and a crash.

    I'm running a development build, so it should have forced internet access.

    Here is the code snippet:
    Code (csharp):
    1.  
    2.     private IEnumerator CheckVersionCoroutine() {
    3.         string url = "http://XXXX:8081/";
    4.        
    5.         string wwwArgs = "?";
    6.         wwwArgs += "cmd=" + "verCheck";
    7.         wwwArgs += "&ver=" + GameVersion.Version;
    8.                
    9.         WWW wwwReq = new WWW(url + wwwArgs);
    10.        
    11.         yield return wwwReq;
    12.         if (wwwReq.error != null) {
    13.             Logging.Log(LogLevel.INFO, "Error checking version: "+wwwReq.error);
    14.             yield break;
    15.         }
    16.  
    17. etc.etc.
    18.  
    19.  

    Here is the logcat dump:

    Any clues?

    Commenting out the version check successfully continues operating the build.

    A few lines further on we also grab (via WWW) a file containing news ticker test - works perfectly fine too.

    So seems like a bug?!

    Seems definitely like an android bug. Never seen it on iOS, web or standalone where we had unreachable webservice etc often enough to have hit this for sure

    Sooo true - I have too many of these. And sometimes I must also admit to not reporting at all when I have things like this where the repro case is either too complicated to do or doesnt trigger the bug :-(

    Baaaaaad me
