I've noticed that Java's @deprecated annotations aren't mapped to C#'s [Obsolete] attributes in Xamarin members (classes, interfaces, methods, properties, events). For example:
android.view.View class's public void setBackgroundDrawable(android.graphics.drawable.Drawable) method is flagged with @deprecated annotation, but in corresponding C# class, there is no System.Obsolete attribute for matching. This occurs in other classes also.
public java.lang.String(byte, int) constructor is deprecated, but it isn't flagged with Obsolete attribute in Xamarin.Android's bind for this class.
We may inadvertently be using obsolete APIs.
Thanks a lot for helping me.
The problem is that our generator doesn't consistently look at the @deprecated information, and thus doesn't generate [Obsolete] when it should.
Dean: See Method.cs!Generate(), and note that it doesn't check the Deprecated property (unlike e.g. GenerateDeclaration()).
Fixed in monodroid/master/9913daff
I have checked this issue with following builds:
Microsoft Visual Studio Professional 2013
Version 12.0.21005.1 REL
Microsoft .NET Framework
Installed Version: Professional
Xamarin 18.104.22.168 (f06bad7)
Xamarin.Android 22.214.171.124 (d507ba60cc907073c9b40ebc88bab6311b748c20)
Xamarin.iOS 126.96.36.199 (8dc6ec80fb6f7c1ec874ad67ffca859cdad94282)
I have checked the definition of "setBackgroundDrawable" and few other method which is deprecated in android and observed that they are mapped with C# "Obsolete" attribute.
This issue has been fixed. Hence, I am closing this issue.
I'm very happy about this news, thanks a lot for help me. Where I can download Xamarin for Visual Studio 188.8.131.52? Or it is an internal alpha release of Xamarin.Android 5.0?
Thanks a lot :D
Has a version containing this fix been released? I've got the same problem and I don't know if I have an old version of if I have hit another case of the same bug.
@Dimitar This bug was fixed in Xamarin.Android 5.0 but is not public yet. Please look at here http://developer.xamarin.com/releases/android/xamarin.android_5/xamarin.android_5.0/
Thanks, it's not fatal, I only needed to know whether to file a new bug.
