delete your app build folder , make project and run it again. — Hemant Parmar

i have no idea if FButton.java is your class or it belongs to any library - you know it better — pskink

The problem comes with the library itself, If you check attrs.xml:

<attr name="buttonColor" format="color" />

As you can see the buttonColor only accepts color value, NOT color reference, and the view is trying to convert reference value you pass in xml to color and it throws an exception, So you can only use color for this attribute ( like this: #000000) Or fork the project and modify attrs.xml like this:

<attr name="buttonColor" format="color|reference" />

fbutton:shadowColor has to be changed too

Try to remove cornerRadius property it's causes the problem may be it's library issues

fbutton:cornerRadius="10dp"

Remove it's all buttons and it's work well
