I am creating an Android keyboard by seeing this tutorial. I saw a similar question here and other sites, but I did not get a solution.
I am trying to embed KeyboardView in my xml . But it shows some rendering problems and exceptions . Here is a snapshot of my Android Studio
Do I need to implement any library or some gradle dependencies ?
