Random Musings on the Android 12 Beta 2
Each time Google releases a follow-on developer preview, I rummage through
the incremental API differences report,
the release notes,
and even the release blog post,
to see if there are things that warrant more attention from
developers. I try to emphasize things that mainstream developers might use but may not
get quite as much attention, because they are buried in the JavaDocs.
Beta 2 has a bit more change in the API surface than I would expect… and yet still
does not have everything that might yet show up in Android 12.
What Google Thinks Is Important
Of the things that Google highlighted in Beta 2, few require developers to do
anything. That is nice, considering that this is Beta 2. For example, apps do not
have to change for the microphone and camera indicators to appear
or for users to be notified about apps reading from the clipboard.
There is a new
which can let you know if the device supports
microphone and camera toggles.
It cannot tell you what the state of the toggle is — you just use the microphone
and camera normally and get silent/blank output if those hardware features are toggled off.
The new Privacy Dashboard is very nice.
If you would like your app to be able to provide explanations for why you used
dangerous permissions, you can export an activity for that,
though pay attention to the docs around
What Quietly Got Documented
Somewhere along the line, without an announcement that I can remember,
AppSearch is now documented.
AppSearch boils down to a full-text search engine, with an API that developers
can use to index content and search it later. The docs specifically compare it to
SQLite’s full-text search capability.
This is certainly a nice addition. The docs point to an
It is unclear what the relationship is between these artifacts and
the Android 12 API.
What Makes Me Wonder “What Are They Waiting For?”
The view translation APIs still exist and received their own updates.
Yet, there is no sign of documentation, the way that stuff crept in for AppSearch.
And, there were some strange reversals, such as
FEATURE_TRANSLATION being removed.
In particular, there is no sign of how apps can control this translation, including
opting out, if the app developers are not in position to support users with Google-supplied
What Is New and (Potentially) Important
There is a new
described as “Required to be able to advertise to nearby Bluetooth devices”. The only
thing that I see as requiring it is
and that only needs it once your
targetSdkVersion reaches 31.
What Continues to Get Sweet, Sweet Love
RemoteViews got more changes.
From the lineup of changes, they feel targeted at app widgets, more so than for
other uses of
RemoteViews (e.g., custom notifications).
Bubbles continue their march towards usefulness:
The new “lights” API got some changes.
It is still unclear what this is all about.
What Notable Got Renamed
The “optimized” storage access from before is now “raw” storage access, as seen in
and related changes to
It still seems limited to file managers and galleries.
What Met Its Untimely(?) Demise
We can no longer ask if a job is a foreground job.
android.service.dataloader package that was added in Beta 1 got nuked in Beta 2.
BluetoothManager is deprecated,
in favor of
getAdapter() has been around since API Level 18, though, so this
change hopefully will not be a big one.
Settings.System is deprecated in favor of
What Else Caught My Eye
The “attribution tags” added in Beta 1 got a bit easier in Beta 2, as it appears
that we may be able to add them in the manifest.
We can find out if our app was granted the ability to schedule exact alarms.
There is a new
We can get and set the “effect color” for
It is unclear whether this refers to the sparkle effect that was seen in earlier
previews. If it does, and your designers hate the sparkle effect with the fiery passion
of a thousand suns, this might lead to an option to disable it within your app.
