Error when copying database from solutions file if you did Ch. 9 Challenge

I copied the database files to my emulator and upon starting the app, I received the following runtime error

 Caused by: java.lang.IllegalStateException: Room cannot verify the data integrity. Looks like you've changed schema but forgot to update the version number. You can simply fix this by increasing the version number.

Upon inspection of the generated Java code and the existing database schema, the provided database file does not contain a column for the requiresPolice field that was added from the Chapter 9 challenge.

If you’re working through the book, then make sure you undo this challenge when using the prepopulated database file. I think one of the best features of this book is carrying the challenges through since to continue patching the additions you need to have a strong understanding of the topics presented in each chapter. I realize this is temporary since at this point we don’t have the features yet to popualte the database, it’s just unfortunate to need to undo a prior step.
