CancelAutoFocus and nuget problem

[guilherme-mantovani]

When I try to scan a barcode in older cellphones there's an error with the camera AutoFocus. I've dowloaded the application and fixed this problem adding a simple try in the file master/Rb.Forms.Barcode.Droid/Camera/CameraConfigurator.cs line 75. e.g. try{ camera.CancelAutoFocus(); } catch (Exception e){ this.Debug(e.Message); } That solves the problem.

Another error is occuring in the last version of the nuget package. When the package is installed the nuget manager corrupts. I've fixed it too changing the nuspec to the folowing (I don't know where the error was).
