    Hi,
    I have one problem with my Android App in Unity 4.6.1f1.
    I have created one C# script for get data from MySQL passing from PHP, and I use WWW request and it work fine, but when I open the App in two or more devices, the first App that I have started died.

    I think that it is a problem of WWW request, because if I open my app in only one device, it works successfully (without any problem). Another thing is that when I open the app with two devices, the first one check the internet connection and say "CONNECTED" the other one say "NOT CONNECTED", and after 10/20 seconds it say "CONNECTED".

    The C# code for get data from PHP:
    Code (CSharp):
    1.  public IEnumerator GetMessage()
    2.     {  
    3.        WWW hs_get = new WWW(highscoreURL);
    4.        yield return hs_get;
    5.        if (hs_get.error != null)
    6.        {
    7.         error = true;
    8.        }
    9.        else
    10.        {
    11.            error = false;
    12.            if(hs_get.text != "")
    13.            {
    14.               // DO ALL TASKS HERE
    15.            }
    16.         }
    17.      }  
    The C# code for check connection:

    Code (CSharp):
    1. private void CheckForInternetConnection()
    2. {
    3.     while(true)
    4.     {
    5.         System.Threading.Thread.Sleep(1000);
    6.         try
    7.         {
    8.             using (WebClient client = new WebClient())
    9.                 using (System.IO.Stream stream = client.OpenRead("http://www.google.com/"))
    10.             {
    11.                 Debug.LogWarning("Online");
    12.                 connected = true;
    13.             }
    14.         }
    15.         catch
    16.         {
    17.              // NOT CONNECTED
    18.              connected = false;
    19.         }
    20.     }  
    21. }

    I have not really looked at your logcat, but it does show that the error is in the call to java.net.NetworkInterface.getNetworkInterfacesList(NetworkInterface.java:304) is causing a null pointer exception.

    But the way you're doing this does not look right (are you using multiple threads?)

    If you're not then then your call to System.Threading.Thread.Sleep(1000); will cause the update loop to pause for the entire duration (not a good thing).

    If you are using multiple threads - you can't call Unity APIs on any thread other than the update thread.

    You would want to use coroutines to do this and not sleep. Look up coroutines if you're not familiar with them.

    Thanks for reply, I use a thread for check connection because with courutine the game lag. For checking connection I do not use WWW class but I use WebClient.
    I use WWW class only for get php data and I use a Courutine for that.

    Ah, yes sorry I did not notice you were using WebClient.

    I'm just taking a punt here, but given the description of the symptoms it sounds like your PHP server is sending data to the first client to cause it to crash. I say this as I can't see any other way that a second device could effect the first device.

    I'm not sure how that can cause that crash though since getNetworkInterfaceList() should never be effected connection oriented data.

    Sorry, I'm not much help here.

    Do not worry, thanks anyway for the answer.
    I'm sure I can find a solution.
    Thanks.

    Note, a bit of googling suggests others have had similar issues on Android:

    https://github.com/square/okhttp/issues/240
    https://code.google.com/p/android/issues/detail?id=76592

    Amongst those two links there are suggestions of it being either a bug in "Alcatel onetouch's implementation of Android." which perhaps your device fits into? Or that it could be related to too many open files.

    I noticed that you recreate the WebClient instance each time (but it's in a using block so you'd expect everything would be cleaned up nicely).. Perhaps try keeping the WebClient instance and reusing it each time, that may avoid additional file handle acquisitions.

    Another long shot - when your second client connects, is any data passed to the first client? Could this data be causing it to open any files (through 3rd party SDKs or in your own code)? I'm thinking that perhaps something goes awry here and leaves no file handles left for the next call to WebClient.. (?)

    Also note there is a fix here for the Alcatel issue: https://github.com/square/okhttp/pull/243/files

    Not sure if that's useful for you though :(
