Description Emin Kokalari 2017-06-03 14:52:35 UTC
It crash when debugging , and sometimes in release mode too with this messages :

E/art     (12972): Nested signal detected - original signal being reported

F/art     (12972): art/runtime/fault_handler.cc:117] Check failed: !initialized_

tried to set Target Android to 23 that didn’t work.

tried running adb shell setprop debug.mono.env
  MONO_DEBUG=soft-breakpoints that didn’t work.

tried to compile using different Android API's Versions


    public void start()
        for (int i = 0; i < 50; i++)
            Task.Run(() => RunScanTcp());
            //Thread thread = new Thread(new ThreadStart(RunScanTcp));

    public void RunScanTcp()
        while (abort != true)
                port = port + 1;
                Log.Info("PORT SCANNER", port.ToString());

Im compiling using :
