Custom controls are not rendered in XAML previewer for Forms.Android platform
The custom controls are not rendered in XAML previewer for Forms.Android platform if we set the font for the custom controls which is accessed from the assets folder.
In our sample, we have written renderer for the CustomLabel in Android platform and set custom font which is accessed from the asset folder for the native view of the corresponding custom control i.e. here native view is "TextView".
We have attached the issue reproduced sample for your reference. Also, please note the custom control is rendered properly in XAML previewer for iOS platform.
This is a potential duplicate of bug 57417
Thanks so much for taking the time to file this bug, @Divakar! :)
As @Jimmy mentioned, this is caused by an issue where the Forms Previewer cannot render custom fonts. I'm marking this bug as a duplicate of that one; once that bug is resolved, this one should be as well (as they have the same underlying root problem).
