1. A Brain-Friendly Guide Android App Dev Tools Head First MOPCON shakalaca
2. Hello ! I’m Shaka • CTO @ SmarTapper Co., Ltd. • Consultant @ SleepNOVA, Inc. http:/ /about.me/shakalaca
3. Today’s topic • Genymotion (101 session) • w/ demo • Gradle (201 session) • w/ sample scripts • Android Studio (201 session)
4. Genymotion
5. Myth :
   App development on Android is FREE (or cheaper) than iOS
6. Really ? • Don’t have to buy a Mac
 ... you’ll buy one eventually (look at me) • There’s an emulator
 ... you really use it ? • Android phone is way cheaper than iPhone !
 ... you mean those in the next page ?
7. http://goo.gl/tt8Rp
8. There’s no such thing as free lunch ..
9. Problems with emulator • No play services (sort of) • No camera • “telnet localhost 5554” doesn’t make sense • f5g really slow in arm based emulator
10. Survival guide ! • Intel x86 Emulator Accelerator • Snapshot or Host GPU
11. Buy real phone(s) ! • For platform/screen specific issues • Nexus is enough ... • ... I’m not sure
12. Developers’ pain https://www.youtube.com/watch?v=cOUK0JZvbwI
13. It’s a bird.. It’s a plane.. It’s Genymotion ! http:/ /www.genymotion.com
14. Is it the one ? • Android x86 emulator based on AndroVM open source project • http:/ /androvm.org/ • (In some case) faster than SDK emulator • Multi-platform • IDE plugins
15. Good for .. • Test applications • Fast & cable free • Screencast • Use your favorite software (for me: QuickTime for OS X)
16. And gamers love it .. https://www.google.com.tw/search?q=神魔之塔+genymotion
17. Features (HW) • Camera • GPS • Battery • Speaker / Microphone • Rotation • Physical keys
18. Features (SW) • API 16 & 17, 18 in preview • Play store (service) • Root access • OpenGL • Virtual keys • Full screen (F11)

21. Demo time !
22. Tips !
23. Control • Buttons • Rotation: ctrl + F11 • Full screen: F11 • Gestures • Zoom: ctrl + mouse left/right • Tile: ctrl + mouse up/down • Rotate: ctrl + shift + mouse left/right
24. Launch from CLI • VBoxManage list vms • "Galaxy Nexus - 4.2.2 - with Google Apps - API 17 - 720x1280" {fbbd7f3e-188d-4a9b-8cdc-5b70c1554f5b} • player --vm-name <VM name/id> • /Application/Genymotion.app/Contents/MacOS/player --vm-name "Galaxy Nexus - 4.2.2 - with Google Apps - API 17 - 720x1280"
25. genyshell • Example: Setup gps to somewhere in Taipei • Content of file “gps_loc” • gps setstatus enabled • gps setlatitude 25.03 • gps setlongitude 121.54 • Command to apply configurations • genyshell -f gps_loc
26. Change resolution • Dummy way: Set in menu before launch • Geek way: Set through adb • adb shell am display-size 800x480 • adb shell am display-density 240 • adb shell am display-size reset • For 4.3+ • adb shell wm size 800x480 • adb shell wm density 240
27. Use my scripts :p • adb root • https:/ /gist.github.com/shakalaca/6716635 • screenshot • https:/ /gist.github.com/shakalaca/6822570 • migration tool • https:/ /github.com/shakalaca/ GenymotionVMMigrationTool
28. Gradle enabled android project
29. What is gradle ? Gradle is build automation evolved. Gradle can automate the building, testing, publishing, deployment and more of software packages or other types of projects such as generated static websites, generated documentation or indeed anything else. ! Gradle combines the power and flexibility of Ant with the dependency management and conventions of Maven into a more effective way to build. Powered by a Groovy DSL and packed with innovation, Gradle provides a declarative way to describe all kinds of builds through sensible defaults. Gradle is quickly becoming the build system of choice for many open source projects, leading edge enterprises and legacy automation challenges. - http:/ /www.gradle.org/
30. .. short version An open source build system that combines the power of Ant & Maven but easy to use
31. Why (google wants to change the build system to) gradle ? • My guess.. • Simplify and unify project dependency management in IDE & CLI • Think about Eclipse & ant (ci server) • Android Studio is coming ! BETA
32. Should I use it ? • For small project • Easy to convert • For large project • Worth trying if it can simplify the configurations (dependency) • For project with variants • Time for better management tool
33. Will it blow up my projects ? It’s 2013 now, you should have SCM … right ?
34. How gradle works ? • Lifecycle • Initialization • Configuration • Execution • Build scripts • build.gradle • settings.gradle (optional) • gradle.properties (optional) http://www.gradle.org/docs/current/userguide/build_lifecycle.html
35. Command • gradle <task name> • tasks • clean • assemble • assembleRelease • assembleDebug • aR / asD
36. Android integration • gradle android plugin • http:/ /tools.android.com/tech-docs/new- build-system/ • output • <project>/build/apk/
37. Step by step tutorial • Basic • Dependency • Sign / Proguard • Variant
39. Eclipse project
41. Dependencies • compile files(‘libs/android-support-v4.jar’) • compile fileTree(dir: ‘libs’, include: ‘*.jar’) • compile ‘com.android.support:support- v4:18.0.0’
42. Android packages ! • com.android.support:support-v4:18.0.0 • com.android.support:appcompat-v7:18.0.0 • com.android.support:gridlayout-v7:18.0.0 • com.android.support:support-v7-mediarouter:18.0.0 • com.android.support:support-v13:18.0.0 • com.google.android.gms:play-services:3.2.65
43. defaultConfig • versionCode • versionName • minSdkVersion • targetSdkVersion • packageName • signingConfig • proguardFile • proguardFiles • testPackageName • testInstrumentation Runner
44. Happy building • Put build.gradle in project directory • Build: gradle assemble • build/apk/ • Install: gradle installDebug or gradle installRelease
45. Step by step tutorial • Basic • Dependency • Sign / Proguard • Variant
46. Project structure
47. app
48. include library project
49. ActionBarSherlock
50. Happy building • Put build.gradle & settings.gradle in app project directory • Put build.gradle in library project directory • Build: gradle assemble • build/apk/
51. settings.gradle • Used in multi-project hierarchy • Define projects to be used in build
52. settings.gradle
53. er.. no direct way ?
56. Known issue • Library project is always “release” build • define your own debug flags.. • <application /> in AndroidManifest.xml
57. Step by step tutorial • Basic • Dependency • Sign / Proguard • Variant
59. Build types • default 2 types: debug & release • for debugging & signing
60. Build types • debuggable • jniDebugBuild • renderscriptDebugBuild • renderscriptOptimLevel • packageNameSuffix • versionNameSuffix • signingConfig • zipAlign • runProguard • proguardFile • proguardFiles
61. Tips • Save your gradle.properties in ~/.gradle/ • .. If you work alone
63. Step by step tutorial • Basic • Dependency • Sign / Proguard • Variant
64. Build variant • Creating different versions of same application • free/paid • multi-apk • Build Variant = Build Type + Product Flavor
65. Product flavor • Defines a customised version of application build by the project • Free / Paid • Amazon / Play Store / blah store • Same type as defaultConfig
67. Build • gradle assemblePaid • gradle aPD / gradle aPR • gradle assembleFree • gradle aFD / gradle aFR
69. One more thing..
70. gradle wrapper • Setup gradle automatically • $ANDROID_HOME/tools/templates/gradle/ wrapper/ • for gradle 1.7+ • execute “gradle wrapper”
72. Compatible with older version of gradle • change gradleVersion • run ‘./gradlew wrapper’
73. Summary • Simple android project • Sign release key • Run proguard • Build variants • Wrapper
74. All samples are here http:/ /github.com/shakalaca/ learning_gradle_android
75. Maven repository
76. Why & How ? • Time is money • Use aar instead of re-compiling everything • aar: Binary distribution of an Android Library Project • http:/ /tools.android.com/tech-docs/new- build-system/aar-format
77. Project layout
78. root-build.gradle
79. library/build.gradle
80. project/build.gradle • archivesBaseName • version
81. app/build.gradle
82. How • deploy library • ./gradlew deploy • use local repository • ./gradlew as -PuseRepo
84. Performance boost • in ~/.gradle/gradle.properties • org.gradle.daemon=true • org.gradle.parallel=true (be careful) • stop the daemon • gradle --stop
85. Refresh cache • --refresh-dependencies • stay up-to-date (?) http://www.gradle.org/docs/current/userguide/ dependency_management.html#sec:cache_command_line_options

88. Q & A
89. Bonus !
91. Remove jars in output apk
92. Remove jars in certain build type
93. Launch after install
94. Move out and rename output apk files • android.applicationVariant.all { variant ->
 variant.assemble.doLast { do_the_magic } 
 } • variant.zipAlign • true: extra variant.outputFile • false: variant.packageApplication.outputFile • https:/ /gist.github.com/shakalaca/6422811
