Migrating to Room: How to do Full Text Search?
Not really. See this issue and this issue where this request is being tracked.
You can always work with the database directly for FTS scenarios, such as creating the table and triggers in your code snippet in the question, by calling getOpenHelper() on the RoomDatabase and using it similar to SQLiteOpenHelper. Room will ignore new tables and stuff that you create behind its back. So, if your FTS work happens to be fairly separate from the rest of your database work, you might be able to go that route.
This feature will be available in Room 2.1.0
