Subject: Error in Android: No JNI_OnLoad found in /system/lib/libc.so 0x413bbd68, skipping init

Tried to connect to a normal OpenFire xmpp server using matrix Mono build. In Unity it works just fine and connects. However, when building for Android it produces the a Matrix.ExceptionEventArgs exception (in OnError method with message "getifaddrs").

The log also produces the following error before calling OnError:

D/dalvikvm(18926): No JNI_OnLoad found in /system/lib/libc.so 0x413bbd68, skipping init

This when calling xmppClient.Open()

Any thoughts?

Best Regards
Jonas Andersson

looks like unity fails when MatriX is looking up the IP address information.

You can try:

xmppClient.ResolveSrvRecords = false;
xmppClient.Hostname = "your_host_or_ip";

Thanks!

It does not however seem to do any difference. This is the code I use:

void setup () {
        xmppClient  = new XmppClient()
            {
               Password = "pass",
                Username = "user2",
                XmppDomain = "xxx.xxx.se",
                Status = "Online",
                Show = Show.chat,
                Port = 5222,
                StartTls = false,
                Hostname = "xxx.xxx.se",
            };
        xmppClient.ResolveSrvRecords = false;
 
        // Event handlers for Matrix
        xmppClient.OnBeforeSasl += xmppClient_OnBeforeSasl;
        xmppClient.OnLogin += this.xmppClient_OnLogin;
        xmppClient.OnAuthError += this.xmppClient_OnAuthError;
        xmppClient.OnError += this.xmppClient_OnError;
        
        xmppClient.OnRosterStart += this.xmppClient_OnRosterStart;
        xmppClient.OnRosterItem += this.xmppClient_OnRosterItem;
        xmppClient.OnRosterEnd += this.xmppClient_OnRosterEnd;
        xmppClient.OnReceiveXml += this.xmppClient_OnReceiveXml;
        xmppClient.OnSendXml += this.xmppClient_OnSendXml;
         
            try
            {
        Debug.Log ("Before Open");
                xmppClient.Open();
        Debug.Log ("After Open");
            }
            catch (Exception ex)
            {
                Debug.Log("During the open");
                Console.WriteLine(ex.Message);
            }
 
            // Get Online users
            xmppClient.OnPresence += this.xmppClient_OnPresence;
            xmppClient.AutoRoster = false;
        Debug.Log("OK So far");
    }

I have no idea then. The problem seems to be in Unity.

This issue occurred for me on Unity 5.3.5f1 when building and deploying to Android using Matrix XMPP.

I was able to fix this issue by setting the API Compatibility Level in the PlayerSettings to ".NET 2.0 Subset" instead of ".NET 2.0".
