Droidcon Kraków 2017 - Gradle Android Recipes Explained

This talk will cover some of the more and less popular Gradle snippets and recipes that Android developers often include in their projects. We will understand exactly how and why they work, so that we can confidently modify them or expand to fit our needs.

1. Łukasz Wasylkowski Gradle Android recipes explained
2. Gradle Configuration scripts Gradle core Gradle plugins Groovy Kotlin Project Task Dependency Extension java android-application retrolambda ❤ ❤ ❤ ❤ ❤
3. Groovy
4. Groovy - parentheses def passToClosure(String param, Closure closure) { closure(param) } Groovy
5. Groovy - parentheses def passToClosure(String param, Closure closure) { closure(param) } passToClosure("param", { println it }) Groovy
6. Groovy - parentheses def passToClosure(String param, Closure closure) { closure(param) } passToClosure("param", { println it }) passToClosure("param") { println it } Groovy
7. Groovy - parentheses def passToClosure(String param, Closure closure) { closure(param) } passToClosure("param", { println it }) passToClosure("param") { println it } passToClosure "param", { println it } Groovy
8. buildscript { ext.kotlinVersion = "1.1.2-4" repositories { jcenter() maven { url 'https:!"maven.fabric.io/public' } google() } … } Groovy - parentheses
9. buildscript { ext.kotlinVersion = "1.1.2-4" repositories { jcenter() maven { url 'https:!"maven.fabric.io/public' } google() } … } buildscript Groovy - parentheses
10. buildscript { ext.kotlinVersion = "1.1.2-4" repositories { jcenter() maven { url 'https:!"maven.fabric.io/public' } google() } … } { ext.kotlinVersion = "1.1.2-4" repositories { jcenter() maven { url 'https:!"maven.fabric.io/public' } google() } … } Groovy - parentheses
11. buildscript { ext.kotlinVersion = "1.1.2-4" repositories { jcenter() maven { url 'https:!"maven.fabric.io/public' } google() } … } ext.kotlinVersion = "1.1.2-4" Groovy - parentheses
12. buildscript { ext.kotlinVersion = "1.1.2-4" repositories { jcenter() maven { url 'https:!"maven.fabric.io/public' } google() } … } repositories Groovy - parentheses
13. buildscript { ext.kotlinVersion = "1.1.2-4" repositories { jcenter() maven { url 'https:!"maven.fabric.io/public' } google() } … } { jcenter() maven { url 'https:!"maven.fabric.io/public' } google() } Groovy - parentheses
14. buildscript { ext.kotlinVersion = "1.1.2-4" repositories { jcenter() maven { url 'https:!"maven.fabric.io/public' } google() } … } jcenter() Groovy - parentheses
15. buildscript { ext.kotlinVersion = "1.1.2-4" repositories { jcenter() maven { url 'https:!"maven.fabric.io/public' } google() } … } maven Groovy - parentheses
16. buildscript { ext.kotlinVersion = "1.1.2-4" repositories { jcenter() maven { url 'https:!"maven.fabric.io/public' } google() } … } { url 'https:!"maven.fabric.io/public' } Groovy - parentheses
17. buildscript { ext.kotlinVersion = "1.1.2-4" repositories { jcenter() maven { url 'https:!"maven.fabric.io/public' } google() } … } url ‘https:!"maven.fabric.io/public' Groovy - parentheses
18. buildscript { ext.kotlinVersion = "1.1.2-4" repositories { jcenter() maven { url 'https:!"maven.fabric.io/public' } google() } … } google() Groovy - parentheses
19. Groovy - map parameters methodWithNamedParams name: "John", age: 25 methodWithNamedParams(name: "John", age: 25)
20. Groovy - map parameters methodWithNamedParams name: "John", age: 25
21. Groovy - map parameters def methodWithNamedParams(Map<String, Object> params) { println params["name"] println "Age: ${params["age"]}" } methodWithNamedParams name: "John", age: 25
22. Groovy - map parameters apply plugin: “com.android.application”
23. Groovy - map parameters apply plugin: “com.android.application” apply(plugin: “com.android.application”)
24. Groovy - map parameters apply plugin: “com.android.application” apply(plugin: “com.android.application”) apply(Map<String, ?> options)
25. Groovy - map parameters apply plugin: “com.android.application” Documentation: • from: A script to apply. • plugin: The id or implementation class of the plugin to apply. • to: The target delegate object or objects. apply(plugin: “com.android.application”) apply(Map<String, ?> options)
26. def helloWorld = { println "Hello World" } Groovy - closures helloWorld()
27. def helloWorld = { println "Hello World" } def helloWorld = { suffix !# println "Hello World$suffix" } Groovy - closures helloWorld() helloWorld("!")
28. def helloWorld = { println "Hello World" } def helloWorld = { suffix !# println "Hello World$suffix" } Groovy - closures def helloWorld = { println "Hello World$it” } helloWorld() helloWorld("!")
29. println square(5) Groovy - closures it * it return def square = { }
30. println square(5) Groovy - closures it * it def square = { }
31. println square(5) Groovy - closures it * it def transform(value, transformation) { transformation(value) } def square = { }
32. println square(5) Groovy - closures it * it def transform(value, transformation) { transformation(value) } println transform(6, square) def square = { }
33. println square(5) Groovy - closures it * it def transform(value, transformation) { transformation(value) } println transform(6, square) println transform(6, { it * it }) def square = { }
34. println square(5) Groovy - closures it * it def transform(value, transformation) { transformation(value) } println transform(6, square) println transform(6, { it * it }) def square = { } println transform(6) { it * it }
35. Groovy - delegates def printClosure = { printText “Hello" }
36. Groovy - delegates class WriterOne { def printText(str) { println "Printed in One: $str" } } class WriterTwo { def printText(str) { println "Printed in Two: $str" } } def printClosure = { printText “Hello" }
37. Groovy - delegates class WriterOne { def printText(str) { println "Printed in One: $str" } } class WriterTwo { def printText(str) { println "Printed in Two: $str" } } def printClosure = { printText “Hello" } printClosure.delegate = new WriterOne() printClosure() !" “Printed in One: Hello”
38. Groovy - delegates class WriterOne { def printText(str) { println "Printed in One: $str" } } class WriterTwo { def printText(str) { println "Printed in Two: $str" } } def printClosure = { printText “Hello" } printClosure.delegate = new WriterOne() printClosure() !" “Printed in One: Hello” printClosure.delegate = new WriterTwo() printClosure() !" "Printed in Two: Hello”
39. Groovy - multiple dispatch class Foo { def methodMissing(String name, def args) { return "$name($args) called" } }
40. Groovy - multiple dispatch class Foo { def methodMissing(String name, def args) { return "$name($args) called" } } new Foo().someUnknownMethod(42)
41. Groovy - multiple dispatch Result: someUnknownMethod([42]) called class Foo { def methodMissing(String name, def args) { return "$name($args) called" } } new Foo().someUnknownMethod(42)
42. Closure vs Action subprojects( Closure closure)
43. Closure vs Action subprojects( Closure closure) @DelegatesTo(Project.class)
44. Closure vs Action subprojects(Action<? super Project> action) subprojects( Closure closure) @DelegatesTo(Project.class)
