4. Android P
5. Android P • Developer Preview 1 ◦ Released March 7 2018 ◦ Initial preview, so not yet stable ◦ Only available by manually flashing your device, or emulator • Developer Preview 2 ◦ Most likely released at Google I/O 2018 ◦ More stable, will be available as OTA update
6. Features • Display Cutout • JobScheduler data cost • Multi-camera • Indoor Positioning • Image Decoder • HDR VP9 Video & HEIF • Neural Networks 1.1 • Notification improvements • Rotation lock • etc...
7. Display Cutout
8. Display cutout For devices like Essential Phone, or iPhone X which have a cutout in the display (for camera, etc).
9. Display cutout Tall Wide Narrow None
10. Display cutout • Clock has moved • Notifications only show on the left • Limited space (Tall only shows 4)
11. Material Design 2
12. Notifications • Images in messaging notifications
13. Notifications • Images in messaging notifications • Messaging notifications now take a Person object for sender instead of CharSequence
14. Activity transitions • Transitions have a new animation • Slide up without fadeout
15. App transitions • Transitions have a new animation • Slide in left/right
16. Gesture navigation • Accidentally leaked by Google • Looks similar to iPhone X navigation
17. Gesture navigation • Another leak?!?
18. ImageDecoder
19. ImageDecoder • More powerful than BitmapFactory • Decode into Bitmap or Drawable • setResize(width, height) • setCrop(rect) • OnHeaderDecodedListener
20. OnHeaderDecodedListener • Callback when image header decoded • Returns ImageInfo ◦ getMimeType() ◦ getSize() ◦ isAnimated()
21. OnPartialImageListener • Callback on failed decode • error: Int • Return false to not throw exception
22. PostProcessor • Called after image decoded ◦ int onPostProcess(Canvas canvas) • Can use this to apply rounded corners etc • Should return if the image is translucent ◦ UNKNOWN - This process didn’t add translucent pixels ◦ TRANSLUCENT - This process added translucent pixels ◦ OPAQUE - This process made the entire image opaque • Returning any other status code will result in IllegalArgumentException
23. ImageDecoder • Support Library?
24. ImageDecoder • Support Library? • Uses Native code, so unlikely. ◦ Can only use ImageDecoder on minSdkVersion 28
25. ImageDecoder • Support Library? • Uses Native code, so unlikely. ◦ Can only use ImageDecoder on minSdkVersion 28 •
26. Others
27. Multi-camera API • Multiple cameras at the same time • ~360 camera emulation? • ???
28. Indoor positioning API • Positioning using Wifi • Requires hardware support (IEEE 802.11mc) ◦ Both on device and access point (AP) • Can use to triangulate location indoors
29. Android Things • Finalized APIs • Looks like it will get a 1.0 release this year
30. Android Things • Finalized APIs • Looks like it will get a 1.0 release this year • 1.0 was released this morning • https://android-developers.googleblog.com/2018/05/say-hello-to-android-thing s-10.html
31. Slice • A slice is a piece of app content and actions that can be surfaced outside of the app. • Similar to RemoteView • For Google Assistant?
32. Flutter • Many sessions for it announced now, so possibly something big • ??? • Flutter Meetup Tokyo #2 (5/31)
33. Flutter • Many sessions for it announced now, so possibly something big • Flutter Beta 3 announced this morning • ??? • Flutter Meetup Tokyo #2 (5/31)
