I'm trying to create a custom ButtonRenderer for Xamarin.Forms. Here is a simple test I've been trying to put up together following some tutorials, but I can's seem to make it work.
Here is my .xaml page:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="TestProject.MainPage">
<ContentPage.Content>
<Button VerticalOptions="Center" HorizontalOptions="Center"></Button>
</ContentPage.Content>
</ContentPage>
And here is my custom rendered: (it is placed in the Android project)
[assembly: ExportRenderer(typeof(Xamarin.Forms.Button), typeof(CustomButtonRenderer))]
namespace TestProject.Droid.CustomRenderers
{
public class CustomButtonRenderer: ButtonRenderer
{
public CustomButtonRenderer(Context context) : base(context)
{
}
protected override void OnElementChanged(ElementChangedEventArgs<Xamarin.Forms.Button> e)
{
base.OnElementChanged(e);
Control.SetBackgroundColor(Android.Graphics.Color.Red);
}
}
}
But it never gets called and my app crashes. My logcat shows:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Java.Lang.ClassNotFoundException: Didn't find class "md5dba8ede99752acada1f5ba384c7cf839.CustomButtonRenderer" on path: DexPathList[[zip file "/data/app/com.companyname.TestProject-1/base.apk"],nativeLibraryDirectories=[/data/app/com.companyname.GN.Mobile.TestProject-1/lib/arm, /data/app/com.companyname.GN.Mobile.TestProject-1/base.apk!/lib/armeabi-v7a, /vendor/lib, /system/lib]]
Am I missing something here?
