How to validate an ENGLISH WORD entered by the user - ANDROID

I'm trying to develop a word-building game (Similar to scrabble) that takes user input and checks whether it is a valid word or not. First, I thought of using an offline dictionary database with SQLite.

But later I realised that there's a BUILT-IN Dictionary (that predicts the words that are being entered in the text fields).

Is there any way that I can use this built-in feature to validate the words entered in my app?

I'm a newbie :)
