I am working on a project on android. I want to attach Gboard into my application because I want to use its functions. I want to use Gboard pad for writing input. I don't want from the user to download Gboard separately. I want to make it a part of application. If possible kindly let me know how.
Id say it is not possible, cannot find anything for Gboard, even virtual keyboard api is deprecated since 2011.
You might want to take a look at creating your own input methods.
