问题 I am working with mono droid, using the mvvmcross framework provided by slodge. However I am having some memory issues. I am disposing bitmaps in the activities ondestroy methods and I am wondering if it is possible to help the GC collecting unused objects of viewmodels.

问题 I have an application, which uses a custom implementation of MyLocationOverlay . In the implementation I set a Bitmap property that is used when it has been specified, by an overload of Draw.

问题 The lastest update of Xamarin Studio changed how syntax highlighting is stored and exported, apparently to make it compatible with Visual Studio, and as a result my customized scheme was lost. I painstakingly reconfigured the scheme and exported it. But now when I try to 'add' the scheme into Xamarin Studio on another computer, nothing happens.

I know this subject is already here in SOF, but I can't find a solution for Xamarin.Android. It's the same for Xamarin.Uwp, no access right.
