Data is not persistent about codelab-android-room-with-a-view

[DAGalpin]

This is by design to make it easier to debug. There is a comment explaining how to make the data persistent.

            // If you want to keep data through app restarts,
            // comment out the following block
            databaseWriteExecutor.execute(() -> {

for the Java version or

                // If you want to keep the data through app restarts,
                // comment out the following line.
                INSTANCE?.let { database ->
                    scope.launch(Dispatchers.IO) {
                        populateDatabase(database.wordDao())
                    }
                }

for the Kotlin one.
