17. Type aliases
18. Don’t expose more than you should
19. lateinit vs by lazy
20. package visibility does not exist in Kotlin • package limits visibility to enclosing folder. internal limits visibility to enclosing module. • Get comfortable with modules!
21. Why modules? • Encourages better code structure • Easier to distribute and reuse • Compiles faster • Convert to an Instant App easily THIS IS GRADLE. IT’S A BUILD SYSTEM FOR THE JVM THAT WORKS THROUGH A BEAUTIFUL DIRECTED ACYCLIC GRAPH MODEL.
22. Module types • Phone & Tablet • Android Library • Java Library • And more…
