I am creating android Keyboard seeing this tutorial. I saw similar question here and other websites but i didn't get the solution.
I am trying to implement KeyboardView into my xml. But it is showing some Rendering problems and Exceptions Here is the snapshot of my Android Studio
Do i need to implement any library or some gradle dependencies ?
