Looks like the vk documentation doesn't show how to enable the vk on a touch device and doesn't specify which platforns is supported in?

can u confirm whether the following documentation is correct?

Some examples are simply incorrect, for example setting a string property in Example 30-1 Setting Email Layout for the Virtual Keyboard
results in an exception:
