Android Android App

I wanted to develop an application on top of the dictionary, that is, an application that uses the dictionary as part of it. Is any dictionary application available on the market available for this purpose? An application that falls under the GPL is preferred. uses a local database instead of using a network connection.

If not, is there any database of dictionaries on the market, at the top of which a dictionary application can be developed, which can then be used for this purpose?

I hope I get it.

Thanks in advance.
