Exception : Type views:BorderlessEntry not found in xmlns clr-namespace:SuaveControls.MaterialForms

[JimmyPun610]

I was trying to use the MaterialEntry in Xamarin Form project. I created a custom control which inherit MatrialEntry to set the default AccentColor.

    public class MyMaterialEntry : MaterialEntry
    {
        public MyMaterialEntry()
        {
            this.AccentColor = (Color)App.Current.Resources["AccentColor"];
        }
    }

Then I use MyMaterialEntry in XAML and run the Android client. Then exception throw.

In MainActivity.cs, I added the Init before/after Forms.Init, but still no luck

        SuaveControls.MaterialForms.Android.Renderers.BorderlessEntryRenderer.Init();
            SuaveControls.MaterialForms.Android.RendererInitializer.Init();

But the control works if I directly use the MaterialEntry directly in XAML

[SuavePirate]

That's a new one. I guess I never tried inheriting from MaterialEntry either. What are your linker settings and what Xamarin.Forms version?

[JimmyPun610]

What do you mean about linker settings? For XF version, I am using the latest 3.0 version.

There is another issue about MaterialButton.

      // we need to reset the StateListAnimator to override the setting of Elevation on touch down and release.
     Control.StateListAnimator = new Animation.StateListAnimator();

In your source code of Android Renderer of Material button, above line will throw exception and crash the app on some Android device with low version, eg, Mine is 4.4.4

[SuavePirate]

If you go to your Android and iOS project settings and go to linker there is a setting there. I want to see if it is getting linked out for some reason.

Also good call on the StateListAnimator. I believe someone has already picked up working on that

[JimmyPun610]

The linker settings is none.

[GuillermoGomezSanchez]

I try to do the same but I couldn't. Is there a fix for this?

[engmsaleh]

Any update or workaround for this error?
