1. Android 11 and the Future Aung Kyaw Paing Mobile Development Team Lead nexlabs
2. 1. Android 11 2. Android Studio 3. Modern Android Development
3. Android 11
4. 1. Built-in screen recording 2. New Media Control 3. Smart Reply 4. Conversations User-sided features
5. Developer sided Features
6. Bubbles - Started from Notification panel - OS-level support
7. <activity android:name=".bubbles.BubbleActivity" android:theme="@style/AppTheme.NoActionBar" android:label="@string/title_activity_bubble" android:allowEmbedded="true" android:resizeableActivity="true" <>
8. </ Create bubble intent val target = Intent(context, BubbleActivity<:class.java) val bubbleIntent = PendingIntent.getActivity(context, 0, target, 0 <* flags </) </ Create bubble metadata val bubbleData = Notification.BubbleMetadata.Builder(bubbleIntent, Icon.createWithResource(context, R.drawable.icon)) .setDesiredHeight(600) .build()
9. </ Create bubble intent val target = Intent(context, BubbleActivity<:class.java) val bubbleIntent = PendingIntent.getActivity(context, 0, target, 0 <* flags </) </ Create bubble metadata val bubbleData = Notification.BubbleMetadata.Builder(bubbleIntent, Icon.createWithResource(context, R.drawable.icon)) .setDesiredHeight(600) .build() </ Create notification val chatPartner = Person.Builder() .setName("Chat partner") .setImportant(true) .build()
10. </ Create bubble intent val target = <<. val bubbleIntent = <<. </ Create bubble metadata val bubbleData = <<. </ Create notification val chatPartner = <<. val builder = Notification.Builder(context, CHANNEL_ID) .setContentIntent(contentIntent) .setSmallIcon(smallIcon) .setBubbleMetadata(bubbleData) .addPerson(chatPartner)
11. Conversations - Show at the top under seperate section - Can promote to bubble - Conversation-specific actions - Mark as priority - Promote to bubble - Silence notification - Custom sounds/vibrations
12. </ Create notification val chatPartner = Person.Builder() .setName("Chat partner") .setImportant(true) .build() </ Use Person in MessageStyle val notification = Notification.Builder(context, channelId) .setStyle( Notification.MessagingStyle.Builder(person) .addMessage(<<.) <<. build() ) .build()
13. WindowInsets - Can listen to WindowInsets animations - Can show keyboard easily - Will be added to appcompat later
14. doOnLayout { </Show windowInsetsController<.show(WindowInsets.Type.ime()) </Hide windowInsetsController<.hide(WindowInsets.Type.ime()) }
15. val animationCallback = object : WindowInsetsAnimation.Callback(DISPATCH_MODE_STOP) { override fun onPrepare(animation: WindowInsetsAnimation) { </TODO } override fun onStart( animation: WindowInsetsAnimation, bounds: WindowInsetsAnimation.Bounds ): WindowInsetsAnimation.Bounds { </TODO } override fun onProgress( insets: WindowInsets, runningAnimations: List<WindowInsetsAnimation> ): WindowInsets { </TODO } override fun onEnd(animation: WindowInsetsAnimation) { </TODO } }

17. Wireless debugging Easily set up Wifi ADB through QR code or pairing code
18. Privacy Updates
19. Scoped Storage - requestLegacyExternalStorage is ignored on Android 11 - Access to all files in shared storage requires read/write file permission
20. One-Time Permission
21. Permission Auto-reset - Auto reset to decline permission after a few months
22. Don’t ask again - If user taps “Decline” more than once, it’s considered as “Don’t ask again”
23. Background Location Permission - Need to be requested separately - Have to request for Foreground Location permission first <manifest <<. > <<<- Required only when requesting background location access on Android 10 (API level 29) and higher. <<> <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" <> </manifest>
24. Tools

26. Database Inspector
27. Android Emulator Window
28. Dagger Navigation
29. Dagger Navigation
30. TFLite
31. Foldable
32. 1. Layout Inspector Live Update On/Off 2. Jetpack Compose support 3. Safe Args Support 4. Accessibility Scanner 5. Multiple Parallel Instrumentation Testing Android Studio 4.2 Preview
33. Modern Android Development
34. https://developer.android.com/modern-and roid-development
35. of Android developers prefer using Kotlin 60%
36. Jetpack
37. 1. Single-Activity Architecture 2. ViewModel+LiveData 3. Dagger 4. Constraint Layout/Jetpack Compose Modern Android Development
38. • No longer recommends multiple activities • Prefer to use Fragment and Nav Arch to structure single-activity Single Activity Architecture
39. ViewModel+LiveData • ViewModel is not MVVM
40. “The description of the class for what it does, matches View Model. That has nothing to do with MVVM. We are not telling you to use or not to use MVVM” -Yigit Boyar (droidcon NYC 2017)
41. ViewModel+LiveData • ViewModel is not MVVM • Understand how LiveData works
42. • Data Store (Protobuffer) • Room • Scoped Storage Persistence Storage
43. • Manual Injection for small project • Dagger for large project Dependency Injection
44. • Constraint Layout • Motion Layout • Jetpack Compose Layouts
