No -tsa or -tsacert is provided and this jar is not timestamped

I'm pretty new to this C# / Xamarin thing. I just "finished" getting a hello world GCM app going. However now, I can't actually launch the application. I'm left with a warning saying:

/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets: Warning: No -tsa or -tsacert is provided and this jar is not timestamped. Without a timestamp, users may not be able to validate this jar after the signer certificate's expiration date (2044-06-21) or after any future revocation date. (Staff)

The application deploys and installs on my device but then won't launch and I can only find it in Settings -> Application Manager. But again, I can't launch it. Suggestions?

    Your launch problem must be something else. The warning is non-critical.

    Any other idea, what could cause that? I'm running the app on an Android Samsung S4

    Take a look at what logcat provides of information. It might give some more insight to what is going wrong.
