In the ch04_27 code sample on page 94, the import statement
import com.masilotti.hikingjournal.R
is marked with the arrow highlighting the code change.
At the top of page 95, the reader is shown a shortcut to create the import statement. The R is not red, and the shortcut is irrelevant since the import statement is added when the reader updates their Tab.kt file with the code changes.
It may be appropriate to leave out the import statement in code sample ch04_27 so that the shortcut directions on page 95 make sense.
