You can refer to this link, do like @atik sarker has said.

Or you can add try-catch to get the error message.

In your code, this line

btnanswer2.SetBackgroundColor(Android.Graphics.Color.ParseColor("0091EA"));

It will throw Java.Lang.IllegalArgumentException: Unknown color

So you need add #, please replace it with btnanswer2.SetBackgroundColor(Android.Graphics.Color.ParseColor("#0091EA"));
