8. Understanding Key concept • How Jetpack Compose Vs View System are distributed • Compilation behavior • What’s the baseline profiler • What’s the advantage of the baseline profiler • How to generate a baseline profiler • Measure the app performance after using the baseline profiler
9. How Jetpack Compose Vs View System are distributed • Unbundle
10. How Jetpack Compose Vs View System are distributed • Unbundle • Compose can be update independently from any specific version of Androïd
11. How Jetpack Compose Vs View System are distributed • Unbundle • Compose can be update independently from any specific version of Androïd • Devices running old version of Android can easily used last compose feature
12. How Jetpack Compose Vs View System are distributed • A library need to be loaded
13. How Jetpack Compose Vs View System are distributed • A library need to be loaded • Need to be interpreted when a feature is needed
14. How Jetpack Compose Vs View System are distributed • A library need to be loaded • Need to be interpreted when a feature is needed • The view system is part of the Android system and no need to be compiled before being used
15. Compilation Behavior Android 1.0 : Interpreted only
16. Compilation Behavior • Initial Performance (After the app installation, after process cold start) : Slow Android 1.0 : Interpreted only
17. Compilation Behavior • Initial Performance (After the app installation, after process cold start) : Slow • Eventual Performance (After the runtime): Slow Android 1.0 : Interpreted only
18. Compilation Behavior • Initial Performance (After the app installation, after process cold start) : Slow • Eventual Performance (After the runtime): Slow • Disk Size (No optimization) : Small Android 1.0 : Interpreted only
19. Compilation Behavior • Initial Performance (After the app installation, after process cold start) : Slow Android 2.2 Froyo : Interpreted + JIT
20. Compilation Behavior • Initial Performance (After the app installation, after process cold start) : Slow • Eventual Performance (After the runtime) : Fast - The JIT will discover hot part and optimized them - Those optimization will disappear when the process died Android 2.2 Froyo : Interpreted + JIT
21. Compilation Behavior • Initial Performance (After the app installation, after process cold start) : Slow • Eventual Performance (After the runtime) : Fast - The JIT will discover hot part and optimized them - Those optimization will disappear when the process died • Disk Size (Optimization disappear when the process died) : Small Android 2.2 Froyo : Interpreted + JIT

38. Compilation Behavior Android 9+ : Cloud Profiles
39. Compilation Behavior Android 9+ : Cloud Profiles It depend to how often your app is used
40. Compilation Behavior Android 9+ : Cloud Profiles,
41. Compilation Behavior • Initial Performance (not compiling the all apk) : Fast Android 9+ : Cloud Profiles
42. Compilation Behavior • Initial Performance (not compiling the all apk, but can depend) : Fast • Eventual Performance (After the runtime) : Fast Android 9+ : Cloud Profiles
43. Compilation Behavior • Initial Performance (not compiling the all apk, but can depend) : Fast • Eventual Performance (After the runtime) : Fast • Disk Size (Few optimizations) : Small Android 9+ : Cloud Profiles
44. Compilation Behavior Android 9+ : Cloud Profiles,
45. Compilation Behavior Android 9+ : Cloud Profiles,
46. Baseline Profiles
47. Baseline Profiles Performance • Include a profile in APK for baseline performance benefits
48. Baseline Profiles App or Libraries • It can be included in libraries to optimize performance for all its consumers

50. Generate Baseline Profiles Jetpack Macrobenchmark Library
51. Generate Baseline Profiles Jetpack Macrobenchmark Library class BaselineProfileGenerator { @get:Rule val baselineProfileRule = BaselineProfileRule() }
52. Generate Baseline Profiles Jetpack Macrobenchmark Library class BaselineProfileGenerator { @get:Rule val baselineProfileRule = BaselineProfileRule() @Test fun generate() {} }
53. Generate Baseline Profiles Jetpack Macrobenchmark Library class BaselineProfileGenerator { @get:Rule val baselineProfileRule = BaselineProfileRule() @Test fun generate() { baselineProfileRule.collectBaselineProfile() } }
54. Generate Baseline Profiles Jetpack Macrobenchmark Library @Test fun generate() { baselineProfileRule.collectBaselineProfile( packageName = "com.example", profileBlock = { this: MacrobenchmarkScope } ) }
55. Generate Baseline Profiles Jetpack Macrobenchmark Library profileBlock = { this: MacrobenchmarkScope :/ a. Most important aspect :/ b. Thinks that worth optimisation }
56. Generate Baseline Profiles Jetpack Macrobenchmark Library profileBlock = { // Start the activity and wait until // The first frame of your activity is rendered startActivityAndWait() }
57. Generate Baseline Profiles Jetpack Macrobenchmark Library profileBlock = { // Start the activity and wait until // The first frame of your activity is rendered startActivityAndWait() device.wait(Until.hasObject(By.res("feed")), 5000) }
58. Generate Baseline Profiles Jetpack Macrobenchmark Library profileBlock = { // Start the activity and wait until // The first frame of your activity is rendered startActivityAndWait() device.wait(Until.hasObject(By.res("feed")), 5000) val feed = device.findObject(By.res("feed")) }
59. Generate Baseline Profiles Jetpack Macrobenchmark Library profileBlock = { // Start the activity and wait until // The first frame of your activity is rendered startActivityAndWait() device.wait(Until.hasObject(By.res("feed")), 5000) val feed = device.findObject(By.res("feed")) feed.fling.(Direction.DOWN) }

62. Baseline Profiles • If you are using a library with baseline profiles, it’ll be merged by the one from the application
63. Baseline Profiles • If you are using a library with baseline profiles, it’ll be merged by the one from the application • Upload it to the playstore so other applications can take advantage of it
64. Baseline Profiles • If you are using a library with baseline profiles, it’ll be merged by the one from the application • Upload it to the playstore so other applications can take advantage of it. • It can be distributed
