Horologist is a group of libraries that aim to supplement Wear OS developers with features that are commonly required by developers but not yet available.

Maintained Versions

The currently maintained branches of Horologist are.

Version	Branch	Min SDK (Wear)	Description
0.5.x	release-0.5.x	25	Wear Compose 1.3.x, Compose 1.6.x, Media3 and some betas of Androidx.
0.6.x	main	26	Wear Compose 1.4.x, Compose 1.7.x and generally latest relevant alphas of Androidx.

Maintenance branches will not delete existing APIs and they should remain stable. However the main branch will actively update to incorporate new API guidance, removing or changing APIs.

---

🎵 Media

Horologist provides the Media Toolkit: a set of libraries to build Media apps on Wear OS and a sample app that you can run to see the toolkit in action.

The toolkit includes:

• horologist-media-ui: common media UI components and screens like PlayerScreen.
• horologist-media: domain model for Media related functionality. Provides an abstraction to the UI module (horologist-media-ui) that is agnostic to the Player implementation.
• horologist-media-data: implementation of the domain module (horologist-media) using Media3.
• horologist-media3-backend: Player on top of Media3 including functionalities such as avoiding playing music on the watch speaker.
• media sample: sample app to listen to downloaded music.

Player Screen	Browse Screen	Entity Screen

📅 Composables

High quality prebuilt composables, such as Time and Date pickers.

• horologist-composables

DatePicker	TimePickerWith12HourClock	TimePicker

SegmentedProgressIndicator	SquareSegmentedProgressIndicator

📐 Compose Layout

Layout related functionality such as a Navigation Aware Scaffold.

• horologist-compose-layout

fillMaxRectangle()

🔲 Compose Material

Opinionated implementation of the components of the Wear Material Compose library , based on the specifications of Wear Material Design Kit .

• horologist-compose-material

🔊 Audio and UI

Domain model for Audio related functionality. Volume Control, Output switching. Subscribing to a Flow of changes in audio or output.

• horologist-audio
• horologist-audio-ui

VolumeScreen

🔐 Auth

Libraries to help developers to build apps following the Sign-In guidelines for Wear OS .

• horologist-auth-composables: composable screens for authentication use cases, with no dependency on the auth-data library.
• horologist-auth-ui: composable screens for authentication use cases, with integration with the auth-data library
• horologist-auth-data: implementation for Wear apps for most of the authentication methods listed in the Authentication on wearables guide.
• horologist-auth-data-phone: implementation for Mobile apps for some of the authentication methods provided by the auth-data library.

horologist's Issues

Utilities for round device padding

For example Modifier.roundDevicePadding(width = 1f). This is sometimes neccesary to add to the final item to ensure it can be scrolled high enough to be not cutoff.

See this clumsy fix https://github.com/joreilly/PeopleInSpace/pull/131/files

Similar to API at https://google.github.io/accompanist/insets/ for insets.

SingleTileLayoutRenderer doesn't expose setFreshnessIntervalMillis

Either make it an overridable param, or expose configuring the builder.

False positives by Paparazzi snapshot tests

Paparazzi snapshot tests does not fail when it should. I don't think it happens 100% of the time, but it's frequently enough.

Previously noticed in #292

Recently noticed after submitting this commit which removes all the usages of WearSnapshotHandler. So all screenshots went from circle to square. And the snapshots tests passed. We can see in the logs in CI that most of the tasks are marked as "UP-TO-DATE" when running verifyPaparazziDebug:

> Task :media-ui:testDebugUnitTest UP-TO-DATE
> Task :media-ui:verifyPaparazziDebug UP-TO-DATE

Potentially related to cashapp/paparazzi#388.

Health services utilities

Building on https://developer.android.com/training/wearables/health-services

Areas to consider

• Service implementation for correct handling of activities
• Storage of Health Data and Activity in Room DB
• Ongoing Activity template
• Mobile/Watch data layer and data syncing.

WearNavScaffold timeText is problematic

The mandatory modifier it is clumsy, we should apply the scaling externally, say in a containing box.

        WearNavScaffold(
            modifier = modifier,
            startDestination = NavigationScreens.Player.route + "?page={page}",
            timeText = {
                    TimeText(modifier = it)
            },

Change implementation of SecondaryPlaceholderChip to use Chip

WHAT

Change implementation of SecondaryPlaceholderChip to use Chip instead of building everything from scratch, and pass the grey shapes as params to label, secondaryLabel, and icon.

PS: remember to remove this dependency from the module when done.

WHY

#328 (comment)

Expected outcome from this task

• Implementation of SecondaryPlaceholderChip is changed to use Chip;
• Preview for SecondaryPlaceholderChip is not affected;
• Snapshot test for SecondaryPlaceholderChip is not affected;

Tiles Image loader utils

Consider a Coil image utility for Tiles

Example https://github.com/android/wear-os-samples/blob/65b0468db06427fdd07c5697ba97afe7c4d5f082/WearTilesKotlin/app/src/main/java/com/example/wear/tiles/messaging/images.kt

WearNavScaffold doesn't work if scrollStateBuilder and AutoCenteringParams conflict

This setup doesn't work because the list can never be in the position where it should show time text.

    WearNavScaffold(
        startDestination = NavScreen.Menu.route,
        navController = navController,
        // state = navState
    ) {
        scalingLazyColumnComposable(
            route = NavScreen.Menu.route,
            scrollStateBuilder = { ScalingLazyListState(initialCenterItemIndex = 0) }
        ) {

    ScalingLazyColumn(
        modifier = modifier.scrollableColumn(focusRequester, scrollState),
        state = scrollState,
        horizontalAlignment = Alignment.CenterHorizontally,
        autoCentering = AutoCenteringParams(itemIndex = 1, itemOffset = 30),
    ) {

Changing autocentering to itemIndex to be 0 works, so this isn't a critical bug.

But also the fix to scrollStateBuilder isn't great either, as it doesn't work for 1/30, but 2,-30 does???

scrollStateBuilder = { ScalingLazyListState(initialCenterItemIndex = 2, initialCenterItemScrollOffset = -30) }

DrawScope adapter for Canvas + Bitmap

A single developer experience for drawn canvas elements. Using DrawScope as the API to make reusable canvas components.

Then render to

• compose Canvas for apps.
• native canvas for watchfaces (potentially complicated by performance considerations)
• bitmap canvas for Tiles, Glance Widgets/Tiles.
• compose canvas for development @previews - for all of the above.

https://developer.android.com/reference/kotlin/androidx/compose/ui/graphics/drawscope/DrawScope

network-selection library

Network selection library for efficient, correct and validated network selection logic in 3P apps.

Uplift the network selection logic from the media reference app.

/**
 * Implementation of app rules for network usage.  A way to implement logic such as
 * - Don't download large media items over BLE.
 * - Only use LTE for downloads if user enabled.
 * - Don't use metered LTE for logs and metrics.
 */
interface NetworkingRules {
    /**
     * Is this request considered high bandwidth and should activate LTE or Wifi.
     */
    fun isHighBandwidthRequest(requestType: RequestType): Boolean

    /**
     * Checks whether this request is allowed on the current network type.
     */
    fun checkValidRequest(
        requestType: RequestType,
        currentNetworkType: NetworkType
    ): RequestCheck

    /**
     * Returns the preferred network for a request.
     */
    fun getPreferredNetwork(
        networks: Networks,
        requestType: RequestType
    ): NetworkStatus?

class NetworkRepository(
    val connectivityManager: ConnectivityManager,
    val coroutineScope: CoroutineScope,
    val logger: NetworkStatusLogger,
) {
...
    val networkStatus: MutableStateFlow<Networks>

Add screenshot tests

The bugs, both caused by framework changes, and 1 I introduced myself show we need more test coverage here.

Add appropriate icon for SeekFowardButton

WHAT

Add appropriate icon for SeekFowardButton for when seekButtonIncrement param is SeekButtonIncrement.Unknown.

WHY

In order to match the icon displayed for SeekBackButton:

SeekBackButton	SeekForwardButton

There is no matching icon in the default material design icon lib.

Paparazzi reports not being archived in CI

After execution of this step in CI we can see in the logs like:

> Task :composables:testDebugUnitTest
See the Paparazzi report at: file:///home/runner/work/horologist/horologist/composables/build/reports/paparazzi/index.html

But the artifacts generated by CI never contain these reports, even after explicitly adding a configuration to archive them in #337.

Change the background colours of the LayoutPreview for Tiles buttons etc.

Currently the entire preview has Gray and Black

Define and use Experimental annotations

A PR like #30 is evidence that we are not stable,
and we build on Alpha software.

We need to use Experimental annotations to make this clear.

Change UI State concept of player

See #286 (comment)

given the UI layer has its own model PlayerUiState, it could be changed to attend the specific needs of the UI classes, e.g. playerUiState.loading instead of playerUiState.connected; or playerUiState.mediaDisplayStatus be either of values Loading, Playing or NotPlaying.

Use modes like playing, loading etc.

Make PlayerRepository getSeekBackIncrement nullable

See #307 (comment)

App crashes after going back from Audio output screen

Media sample app freezes and crashes after going back (swipe back without selecting any output) from Audio output screen. This only happens if the Audio output screen is launched after pushing the "play" button on the player screen. If the Audio output button is pushed instead, the issue does NOT happen.

Video:

Device: Galaxy Watch4 Classic (4W2J) - SM-R895F

Steps to reproduce

1. Make sure the watch does not have any bluetooth device connected
2. Launch app - player screen is displayed with a media
3. Push play - bluetooth settings screen is displayed
4. Swipe back

Expected result

Player screen is displayed, in an idle/paused state, and app is not frozen.

Actual result

Player screen is displayed, in an idle/paused state, but app is frozen (nothing happens when tapping on any buttons) and after few seconds the app closes (crashes).

Refactor media-ui navigation

See #300 (comment)

But also we should have a nicer API for params extraction and also building the params to navigate to.

DatePicker day position issue

Issue

The day picker is not keeping the position of the previously selected day when going to the month picker and coming back to the day picker.

Steps to reproduce

There are few ways of reproducing it, as you can see in the gif attached below, but here is one:

1. Pick Jan as month
2. Pick 31 as day
3. Pick Feb as month; day should change automatically to 28
4. Go back to day picker; do not scroll or pick another day
5. Pick Jan as month
6. Go back to day picker

Expected result

Day picker should display day 28.

Actual result

Day picker displays day in between 30 and 31.

Bluetooth settings screen does not stay open when there is a connected device

When launched from the Media sample app, the bluetooth settings screen does not stay open when there is a connected device.

cannot_open_audiooutput_screen.mp4

Devices:

• Galaxy Watch4 Classic (4W2J) - SM-R895F
• Galaxy Buds2 - SM-R177

Steps to reproduce

1. Make sure the watch has a bluetooth device connected to it
2. Launch app - player screen is displayed with a media
3. Push Audio output button

Expected result

Bluetooth settings screen is displayed.

Actual result

Bluetooth settings screen is launched and closed immediately.

In Time/Date Pickers, use the Button to step through the columns before it becomes a 'commit'

I think it would be good for the Button on the multi-picker screens to step through the pickers. For example, start on Day and offer '>', and clicking takes you to the Month (stays as a '>'), then when you click onto the Year, it changes to the Check icon and commits the choice.

Add support for WEBP or PNG with transparency to Tiles image helpers

The current conversion code for bitmaps and canvas elements to Tile ImageResources, uses RGB_565.

horologist/tiles/src/main/java/com/google/android/horologist/tiles/images/images.kt

Line 69 in 40801e6

public fun Bitmap.toImageResource(): ImageResource {

This is safe format, but requires extra work and also does not support alpha channel.

We should add a flag to support other formats including png, webp.

This probably involves removing hard coded format when flag is set

setFormat(ResourceBuilders.IMAGE_FORMAT_RGB_565)

and use, or other conversion code.

    val bytes = ByteArrayOutputStream().apply {
        compress(Bitmap.CompressFormat.PNG, 100, this)
    }.toByteArray()

We can assume Coil for our conversion code if it helps, and to start with avoiding conversions, but to be confirmed.

A later change might be also this code path https://github.com/google/horologist/blob/2f15272f92291bcdbdacd66b1042e42802c45cb7/tiles/src/main/java/com/google/android/horologist/tiles/canvas/canvas.kt

Make Seconds optional in TimePickers

Add Id to ImageResource mapper

fun idToImageResource(id: Int) = ImageResource.Builder()
       .setAndroidResourceByResId(
               AndroidImageResourceByResId.Builder()
                       .setResourceId(id)
                       .build()
       )

I'm using it for a component audit (in combination with LayoutPreview) but presumably it's handy for the tile renderer too.

Audio output chip on VolumeScreen is not displayed with full width

The audio output chip on the VolumeScreen is displayed with full width on the screenshot at the page: https://google.github.io/horologist/audio-ui/

However, the chip does not seem to be taking the full width available of the screen:

physical watch	android studio preview

PS: I also checked the preview with d29eed9 (before project was updated to wear compose beta02) and the result is the same.

Media title is being trimmed

On the Media sample app, the media title is being trimmed on the left side:

Devices:

• Galaxy Watch4 Classic (4W2J) - SM-R895F
• Emulator - Wear OS Large Round API 30

The issue become apparent on the PlayerScreen preview once the title length is increased:

Resolve on screen content with translations

See #286 (comment)

nit: I see the benefit of the library providing default content descriptions to the icons it displays (which can be overridden to provide translations) but I feel that displaying a text on the screen in a specific language by default is more invasive and would rather require this as parameter to the component - I might be biased and maybe I should not see any difference in between these two scenarios

StandardChip placeholder icon color not changing when disabled

StandardChip placeholder icon should have an alpha applied in order to change the color when on disabled state.

Compare:

Our implementation relies on Chip from androidx.wear.compose.material which seems to implement this functionality. From the kdoc:

In order to correctly render when the Chip is not enabled the icon must set its alpha value to [LocalContentAlpha].

However, our implementation uses Coil's rememberAsyncImagePainter to display a placeholder, which receives a Painter type as placeholder, and might not work well with that alpha applied in Chip.

Expected outcome from this task

• PrimaryChip preview for disabled state displays placeholder icon with correct alpha applied
• SecondaryChip preview for disabled state displays placeholder icon with correct alpha applied
• Other previews for PrimaryChip and SecondaryChip are not affected
• PrimaryChip snapshot test for disabled state displays placeholder icon with correct alpha applied
• SecondaryChip snapshot test for disabled state displays placeholder icon with correct alpha applied
• Other snapshot tests for PrimaryChip and SecondaryChip are not affected

Complete WearNavScaffold functionality

• Review APIs
• Screenshot tests
• Theming, customising (date range, error states)

Photos Picker

Look if we can build upon https://google.github.io/modernstorage/

And provide photos pickers for

• Remote / API catalogs?
• Local storage
• Paired Mobile (with Helper?)

Do not run tests with LargeTest annotation in CI

WHAT

Do not run tests with LargeTest annotation in CI.

WHY

It was the intention of #304

However, it looks like they are still running as this recent PR failed with:

com.google.android.horologist.mediasample.playback.PlaybackNotificationTest > testCausesNotification[test(AVD) - 9] FAILED 
	expected to be true
	at com.google.android.horologist.mediasample.playback.PlaybackNotificationTest$testCausesNotification$1$1.invokeSuspend(PlaybackNotificationTest.kt:63)
Tests on test(AVD) - 9 failed: There was 1 failure(s).

And the test that failed is annotated with LargeTest.

Update plugin versions to use catalog also

id "com.diffplug.spotless" version "5.9.0"

should be

alias(libs.plugins.spotless) apply false

Currency Picker

Implement a picker for Currency amounts.
