What am I doing that is causing a crash on the framework?

You are using a KeyboardView without setting the OnKeyboardActionListener:

mKeyboardView.setOnKeyboardActionListener(new OnKeyboardActionListener() {

    @Override
    public void onKey(int primaryCode, int[] keyCodes) {
    }

    @Override
    public void swipeUp() {
    }

    @Override
    public void swipeRight() {
    }

    @Override
    public void swipeLeft() {
    }

    @Override
    public void swipeDown() {
    }

    @Override
    public void onText(CharSequence text) {
    }

    @Override
    public void onRelease(int primaryCode) {
    }

    @Override
    public void onPress(int primaryCode) {
    }

}
