Good to hear you got it fixed :) Tooling is one thing, but it pays to sometimes apply some old school handcoding.

I had a feeling that was why. Anyway I wrote my own implementation in C# using Mono.Data.Sqlite with my own version of the ContentValues class. It now executes in 1/4 of the time. -----Original Message----- From: monodroid-boun...@lists.ximian.com [mailto:monodroid-boun...@lists.ximian.com] On Behalf Of Jonathan Pryor Sent: Sunday, January 06, 2013 10:34 PM To: Discussions related to Mono for Android Subject: Re: [mono-android] Copying data between Dalvik and Mono... major slowdown.

The generator does not; it can change on a method-by-method basis, and the generator needs to generate code to support it. > url certainly doesn't get the same treatment. `url` isn't an array, and thus has "pass by value" semantics. For example, consider this potential Java method: public int bulkInsert(Uri url, ContentValues[] values) { url = new Url (...); values [0] = new ContentValues (...); } The caller of `bulkInsert()` will _not_ be able to see that bulkInsert() modified `url`. That is _not_ true for `values[0]`; the caller _will_ be able to see the change performed to `values[0]`, were it to be changed. - Jon _______________________________________________ Monodroid mailing list Monodroid@lists.ximian.com UNSUBSCRIBE INFORMATION: http://lists.ximian.com/mailman/listinfo/monodroid _______________________________________________ Monodroid mailing list Monodroid@lists.ximian.com UNSUBSCRIBE INFORMATION: http://lists.ximian.com/mailman/listinfo/monodroid Op dit e-mailbericht is de disclaimer van Info Support van toepassing, zie http://www.infosupport.com/disclaimer _______________________________________________ Monodroid mailing list Monodroid@lists.ximian.com UNSUBSCRIBE INFORMATION: http://lists.ximian.com/mailman/listinfo/monodroid
