I doubt that this will work, as I doubt that the myGIApp finalizer will ever be invoked. The Application instance is a singleton that is alive for as long as the process lives, and when Android exits the process Android doesn't give the GC a chance to run (why should it?), and even if it did give the Dalvik GC a chance to run it's highly unlikely that Mono's GC would get a chance to run, and if Mono's GC doesn't run (AND find that Dalvik is no longer referencing the Java-side Application instance!), then Mono's GC won't execute the finalizer.

In short, I think it's a safe bet that the Application finalizer will never run, period.

Finally, as a point of style, you should never provide a finalizer for Java.Lang.Object subclasses. You should instead override Java.Lang.Object.Dispose(bool):
