DANIEL GALPIN: Welcome to Now in Android,
your ongoing guide to what's new and notable in the world
of Android development.
In this episode, we'll be covering day two of Android Dev
Summit focused on form factors, the Health Services Jetpack
Beta, a ton of updates to Google Play, Android
performance, and more.
The second day of Android Dev Summit 2022
kicked off live from London with updates on Android form
factors, including large screens, wearables, cars,
and TVs.
The full YouTube playlist has more
about how your apps can take advantage of the growing
portfolio of large-screen devices,
such as tablets, desktops, and foldables,
how we're making it simpler than ever
to develop for Wear OS, best practices for TV development,
and what's new in car development.
And make sure to tune in on November 14,
at 9:00 AM PST for the final Android Dev Summit livestream,
focused on how to best leverage Android Platform innovations.
We covered the beta updates to the Health Services API,
which enables Wear OS 3 apps to take
advantage of on-device sensor data
and related algorithms corresponding to activity,
exercise, and health without having
to choose between conserving battery life
and getting high frequency data.
It introduces new data and exercise types,
the ability to listen for health events, such as fall detection,
a new organization model for data and health services
that makes the API more type-safe,
new ExerciseStates that give you more control over how
your app responds to an ending exercise, new passive listener
APIs, and more.
Google Play covered lots of big platform updates,
including expanding LiveOps and renaming it
to Promotional Content, Churned-user Custom Store
Listings, new technical quality thresholds
for user-perceived crash rates and ANRs, an improved purchase
experience, more flexibility and control
over your subscriptions, new monetization
insights, new safety initiatives and policies,
the global expansion of the Google Play Games beta on PC,
and more.
Over in Articles, Diana covered how to consider reachability--
what parts of the screen users can comfortably reach without
stretching or adjusting their grip--
when deciding where to place an app's UI elements.
The article considers hand size, device orientation,
and how best to utilize the edges and top of the screen.
In "Accurately Measure Android App Performance
With Profileable Builds," Yi covers
how to use the Profileable tag on devices running Android
10 or higher to enable profiling tools that measure timing
information without the performance overhead of a debug
build.
The blog explains when to use a release build,
a profileable release build, or a debug build.
There are so many great videos from the Form Factors
livestream.
For a quick summary, Alex presented his top three picks
from the Form Factors track in ADS '22
while the live Form Factors #AskAndroid panel answered
your questions on large screens, foldables, wearables, and TVs.
We had lots of sessions on how to handle your UI for larger
screens, including Chrome OS.
We also dove deeply into wearables,
covered improving the TV user experience,
and what's new with the Car App Library.
We also had talks that covered technologies that
spanned these form factors.
Over in Android X, the first release candidate
of Wear Composed Version 1.1 went out,
along with Car App Version 1.2, and TV Version 1.0 alpha 2.
Media Router Version 1.4 alpha 1 added SystemOutputSwit
cherDialogController.showDialog to show either the system's
output switcher dialog or the Bluetooth settings
fragment on Wear devices.
Privacy Sandbox Tools version 1.0 alpha 1
is a new Jetpack library that contains APIs
for utilizing the Privacy Sandbox functionality
while Camera Version 1.3 alpha 1 now officially includes
Camera Viewfinder, providing a base viewfinder
widget that can display the Camera 2 camera feed.
Datastore Version 1.1 alpha 1 now
can support data consistency in multi-process use cases
and has a new storage interface which
abstracts the underlying storage mechanism for Datastore
with implementations provided for Java.io and okio.
Finally, in episode 190 of Android Developers Backstage,
Tor and Chet learned some more about performance
from Carmen, an expert on everything
related to performance from the Android Platform Performance
team.
The perfect episode for you if you ever
wanted to learn more about R8, Perfetto,
baseline profiles, custom performance tracing, power
metrics, and more.
So that's it for this week with Android Dev Summit and its Form
Factors track, Health Services, Google Play updates,
Performance, and more.
