8. DYNAMIC DELIVERY
9. PREREQUESITES Android 5.0 Google Play installed and up-to-date Give your signing Keystore to Google
10. DYNAMIC DELIVERY 1. Architecture
11. Application Library implementation
12. Application Library implementation apply plugin: 'com.android.application' dependencies { implementation "com.google.zxing:core:3.4.0" } // Application class com.google.zxing.MultiFormatWriter().encode( value, BarcodeFormat.QR_CODE, 500, 500, null ) apply plugin: 'com.android.library'
13. Application Library implementation
14. Application Dynamic Feature
15. Application Dynamic Feature implementation dynamicFeature
16. Application Dynamic Feature implementation dynamicFeature apply plugin: 'com.android.dynamic-feature' dependencies { implementation project(':App') } apply plugin: 'com.android.application' android { dynamicFeatures = [":StockFeature"] }
17. apply plugin: 'com.android.dynamic-feature' dependencies { implementation project(':App') } apply plugin: 'com.android.application' android { dynamicFeatures = [":StockFeature"] } // MainActivity.kt StockEntrypoint.showActivity(context) Application MainActivity.kt Dynamic Feature (Stock Feature) StockEntrypoint.kt implementation dynamicFeature // MainActivity.kt StockEntrypoint.showActivity(context)
18. Application MainActivity.kt Dynamic Feature (Stock Feature) StockEntrypoint.kt implementation dynamicFeature apply plugin: 'com.android.dynamic-feature' dependencies { implementation project(':App') } apply plugin: 'com.android.application' android { dynamicFeatures = [":StockFeature"] } // StockActivity.ky (this.application as MyApplication) .getDaggerComponent()
19. DYNAMIC DELIVERY 2. Develop
20. CREATE YOUR 1st FEATURE
21. Delivery mode Install Time OnDemand Device dependent <dist:module dist:title="@string/module_name_stock"> <dist:delivery> <dist:install-time /> </dist:delivery> </dist:module> <dist:module dist:title="@string/module_name_stock"> <dist:delivery> <dist:on-demand /> </dist:delivery> </dist:module> <dist:module dist:title="@string/module_name_payment"> <dist:delivery> <dist:install-time> <dist:conditions> <dist:device-feature dist:name="android.hardware.nfc.hce" /> </dist:conditions> </dist:install-time> </dist:delivery> </dist:module> CREATE YOUR 1st FEATURE
22. WRITE FROM SCRATCH REFACTOR YOUR APP 1 2 Keep a single module Refactor in feature package Move your code Fix remaining errors Don’t move everything at the same time

51. o One time usage o No installation process o Accessible via - “Try now” on the Play Store - HTTP(s) links INSTANT APPS Limited access to device Secure network request only Google requirements Android 5.0
52. 2016 Google IO 2018 Google IO 2018 ADS A LONG WAY …
53. INSTANT APPS 1. Develop
54. MAKE YOUR APP INSTANT Try Now apply plugin: 'com.android.application’ 1- Inside your Android module
55. MAKE YOUR APP INSTANT Try Now apply plugin: 'com.android.application’ <dist:module dist:instant="true" /> 1- Inside your Android module 2- Declare your App as instant
56. MAKE YOUR APP INSTANT Try Now apply plugin: 'com.android.application’ <dist:module dist:instant="true" /> <meta-data android:name="default-url" android:value="{{URL}}" /> 1- Inside your Android module 2- Declare your App as instant 3- Declare the main entrypoint
57. MAKE YOUR APP INSTANT Through a link 1- Declare your deep link <intent-filter android:autoVerify="true"> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.BROWSABLE" /> <category android:name="android.intent.category.DEFAULT" /> <data android:host="sample.dfournier.me" /> <data android:pathPattern="/stock/share/.*" /> <data android:scheme="https" /> <data android:scheme="http" /> </intent-filter>
58. MAKE YOUR APP INSTANT Through a link 1- Declare your deep link 2- Authentify your app on your domain <intent-filter android:autoVerify="true"> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.BROWSABLE" /> <category android:name="android.intent.category.DEFAULT" /> <data android:host="sample.dfournier.me" /> <data android:pathPattern="/stock/share/.*" /> <data android:scheme="https" /> <data android:scheme="http" /> </intent-filter> https://{{YourDomain}}/.well-known/assetlinks.json [ { "relation": [ "delegate_permission/common.handle_all_urls" ], "target": { "namespace": "android_app", "package_name": "me.dfournier.sample", "sha256_cert_fingerprints": [ "65:7E:58:05:6B:A7:59…" ] } } ]
59. <intent-filter android:autoVerify="true"> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.BROWSABLE" /> <category android:name="android.intent.category.DEFAULT" /> <data android:host="sample.dfournier.me" /> <data android:pathPattern="/stock/share/.*" /> <data android:scheme="https" /> <data android:scheme="http" /> </intent-filter> INSTANT DYNAMIC FEATURE ?
60. <intent-filter android:autoVerify="true"> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.BROWSABLE" /> <category android:name="android.intent.category.DEFAULT" /> <data android:host="sample.dfournier.me" /> <data android:pathPattern="/stock/share/.*" /> <data android:scheme="https" /> <data android:scheme="http" /> </intent-filter> INSTANT DYNAMIC FEATURE ?
61. <dist:module dist:title="@string/module_title_subscribe"> <dist:delivery> <dist:install-time /> </dist:delivery> </dist:module> INSTANT DYNAMIC FEATURE !
62. INSTANT DYNAMIC FEATURE ! A feature cannot be instant and on-demand <dist:module dist:instant="true" dist:title="@string/module_title_subscribe"> <dist:delivery> <dist:install-time /> </dist:delivery> </dist:module>
63. INSTANT APPS 3. Explicit UX
65. INSTANT APPS UX InstantApps.getPackageManagerCompat(context).isInstantApp o Adapt the UI for Instant Experience o Suggest the installation o Persist user setting through launch / installation o The user may encounter a confirmation window o Use Google SmartLock for authentication fun showInstallPrompt( activity: Activity, postInstallIntent: Intent, requestCode: Int, referrer: String?): Boolean
66. o Get your SHA on the Play Console o Manage environment with variants and manifestPlaceholders o Declare several app on your domain o Keep track of unused resources & APK size o Extract large data into another feature module TIPS
67. INSTANT APPS 4. Test & Distribute
68. Google Play Console Android Studio TEST & DISTRIBUTE ia run [-s=<deviceSerial>] [-u=<url>] [<appArtifact>...] ia check [-i=<installableApk>] <appArtifact>...
