Xamarin.Management.Tools

Tools to track and manage your Xamarin applications

Getting Started

• Install the Xamarin.Management.Tools package

Install-Package Xamarin.Management.Tools -Version 1.0.1

SyncContextTracker

Track your application SynchroniationContext to detect deadlocks and potential deadlocks

• For Xamarin.Forms application

    public partial class App {

        protected override void OnStart() =>
            SyncContextTracker.Start(SyncContextTrackerMode.ReportPotentialDeadlocks);

        protected override void OnSleep() {
        }

        protected override void OnResume() {
        }
    }

• For Xamarin.Android (without Xamarin.Forms)

    public class MainActivity : AppCompatActivity {
        protected override void OnCreate(Bundle savedInstanceState) {
            base.OnCreate(savedInstanceState);
            SyncContextTracker.Start(SyncContextTrackerMode.ReportPotentialDeadlocks);
        }
    }

• For Xamarin.IOS (without Xamarin.Forms)

    [Register("AppDelegate")]
    public partial class AppDelegate : FormsApplicationDelegate {
        public override bool FinishedLaunching(UIApplication app, NSDictionary options) {
           SyncContextTracker.Start(SyncContextTrackerMode.ReportPotentialDeadlocks);
           base.FinishedLaunching(app, options);
        }
    }

Dalvik VM (Android)

Track the GRefs on your Android application

    [Application]
    public class MainApplication : Application {
        protected MainApplication(IntPtr javaReference, JniHandleOwnership transfer)
            : base(javaReference, transfer) { }

        public override void OnCreate() {
            base.OnCreate();

            Dalvik.SetupGlobalRefDump();
        }
    }

This will provide a log every 3 seconds, you can also configure a custom interval

    var vm = Dalvik();
    Dalvik.SetupGlobalRefDump(TimeSpan.FromSeconds(5));
    ....

    //Don't forget to discard it
    vm.Dispose();
