1. What's new in AGP 3.0
7. https://blog.gradle.org/incremental-compiler-avoidance Compiler avoidance
8. Dependencies and modules
12. // build.gradle (app) compile project(':A') compile project(':B') // build.gradle (A) compile project(':C') // build.gradle (B) compile project(':D') // ...
14. fun foo(): Bar { return Bar() }
15. fun foo(): Bar { println("Executing foo") return Bar() }
17. fun foo(): Bar { println("Executing foo") return Bar() }
18. fun foo(parameter: Boolean): Bar { // ... }
20. // build.gradle (app) implementation project(':A') implementation project(':B') // build.gradle (A) implementation project(':C') // build.gradle (B) implementation project(':D') // ...
21. fun foo(parameter: Boolean): Bar { // ... }
23. Multi module projects may build faster!
24. data class Bar(val value: Int = 0)
25. fun someFunInD() = Bar() data class Bar(val value: Int = 0)
26. data class Bar(val value: Int = 0) fun someFunInD() = Bar() Leaked Interface
27. // build.gradle (D) api project(':E')
28. // build.gradle (D) api project(':E')
29. Migrating Libraries compile -> implementation Modules compile -> implementation On demand compile -> api Declaring dependencies
31. Flavors
32. //build.gradle productFlavors { production { dimension "minSdkVersion" } development { dimension "minSdkVersion" minSdkVersion 21 Flavor dimensions
33. Dexing
34. //gradle.properties android.enableD8 = true android.enableD8.desugaring = true Dexing with D8
35. Resources
36. //gradle.properties android.enableAapt2 = true AAPT2
