Fitur dan API

Android 16 memperkenalkan fitur dan API baru yang hebat untuk para developer. Bagian berikut merangkum fitur ini untuk membantu Anda mulai menggunakan API terkait.

Anda juga harus meninjau area tempat perubahan platform dapat memengaruhi aplikasi Anda. Untuk informasi selengkapnya, lihat halaman berikut:

• Perubahan perilaku yang memengaruhi aplikasi saat menargetkan Android 16
• Perubahan perilaku yang memengaruhi semua aplikasi terlepas dari targetSdkVersion.

Fungsi inti

Android menyertakan API baru yang memperluas kemampuan inti sistem Android.

Dua rilis Android API pada tahun 2025

• This preview is for the next major release of Android with a planned launch in Q2 of 2025. This release is similar to all of our API releases in the past, where we can have planned behavior changes that are often tied to a targetSdkVersion.
• We're planning the major release a quarter earlier (Q2 rather than Q3 in prior years) to better align with the schedule of device launches across our ecosystem, so more devices can get the major release of Android sooner. With the major release coming in Q2, you'll need to do your annual compatibility testing a few months earlier than in previous years to make sure your apps are ready.
• We plan to have another release in Q4 of 2025 which also will include new developer APIs. The Q2 major release will be the only release in 2025 to include planned behavior changes that could affect apps.

In addition to new developer APIs, the Q4 minor release will pick up feature updates, optimizations, and bug fixes; it will not include any app-impacting behavior changes.

We'll continue to have quarterly Android releases. The Q1 and Q3 updates in-between the API releases will provide incremental updates to help ensure continuous quality. We're actively working with our device partners to bring the Q2 release to as many devices as possible.

Using new APIs with major and minor releases

Guarding a code block with a check for API level is done today using the SDK_INT constant with VERSION_CODES. This will continue to be supported for major Android releases.

if (SDK_INT >= VERSION_CODES.BAKLAVA) {
  // Use APIs introduced in Android 16
}

The new SDK_INT_FULL constant can be used for API checks against both major and minor versions with the new VERSION_CODES_FULL enumeration.

if (SDK_INT_FULL >= VERSION_CODES_FULL.[MAJOR or MINOR RELEASE]) {
  // Use APIs introduced in a major or minor release
}

You can also use the Build.getMinorSdkVersion() method to get just the minor SDK version.

val minorSdkVersion = Build.getMinorSdkVersion(VERSION_CODES_FULL.BAKLAVA)

These APIs have not yet been finalized and are subject to change, so please send us feedback if you have any concerns.

Pengalaman pengguna dan UI sistem

Android 16 memberi developer dan pengguna aplikasi kontrol dan fleksibilitas yang lebih besar untuk mengonfigurasi perangkat agar sesuai dengan kebutuhan mereka.

Notifikasi yang berfokus pada progres

Android 16 memperkenalkan notifikasi yang berfokus pada progres untuk membantu pengguna melacak perjalanan awal hingga akhir yang dimulai pengguna dengan lancar.

Notification.ProgressStyle adalah gaya notifikasi baru yang memungkinkan Anda membuat notifikasi yang berfokus pada progres. Kasus penggunaan utama mencakup transportasi online, pengiriman, dan navigasi. Dalam class Notification.ProgressStyle, Anda dapat menunjukkan status dan tonggak pencapaian dalam perjalanan pengguna menggunakan titik dan segmen.

To learn more, see the Progress-centric notifications documentation page.

Notifikasi yang berfokus pada progres yang ditampilkan di layar kunci.

Notifikasi yang berfokus pada progres yang ditampilkan di panel notifikasi.

Pembaruan kembali prediktif

Android 16 adds new APIs to help you enable predictive back system animations in gesture navigation such as the back-to-home animation. Registering the onBackInvokedCallback with the new PRIORITY_SYSTEM_NAVIGATION_OBSERVER allows your app to receive the regular onBackInvoked call whenever the system handles a back navigation without impacting the normal back navigation flow.

Android 16 additionally adds the finishAndRemoveTaskCallback() and moveTaskToBackCallback. By registering these callbacks with the OnBackInvokedDispatcher, the system can trigger specific behaviors and play corresponding ahead-of-time animations when the back gesture is invoked.

Haptik yang lebih kaya

Android telah mengekspos kontrol atas aktuator haptic sejak awal.

Android 11 menambahkan dukungan untuk efek haptik yang lebih kompleks yang dapat didukung oleh aktuator yang lebih canggih melalui VibrationEffect.Compositions dari primitif semantik yang ditentukan perangkat.

Android 16 menambahkan API haptik yang memungkinkan aplikasi menentukan kurva amplitudo dan frekuensi efek haptik sekaligus memisahkan perbedaan antara kemampuan perangkat.

Alat dan produktivitas developer

Meskipun sebagian besar upaya kami untuk meningkatkan produktivitas Anda berpusat pada alat seperti Android Studio, Jetpack Compose, dan library Android Jetpack, kami selalu mencari cara di platform untuk membantu Anda mewujudkan visi Anda.

Penanganan konten untuk wallpaper animasi

在 Android 16 中，动态壁纸框架将获得一个新的 content API，以应对由用户驱动的动态壁纸带来的挑战。目前，包含用户提供的内容的实时壁纸需要复杂的服务专用实现。Android 16 引入了 WallpaperDescription 和 WallpaperInstance。借助 WallpaperDescription，您可以识别同一服务中的动态壁纸的不同实例。例如，如果某张壁纸同时在主屏幕和锁定屏幕上显示，则这两种情况下显示的内容可能各不相同。壁纸选择器和 WallpaperManager 会使用此元数据更好地向用户呈现壁纸，从而简化创建多样化个性化动态壁纸体验的过程。

Performa dan baterai

Android 16 memperkenalkan API yang membantu mengumpulkan insight tentang aplikasi Anda.

Pembuatan profil yang dipicu sistem

ProfilingManager was added in Android 15, giving apps the ability to request profiling data collection using Perfetto on public devices in the field. However, since this profiling must be started from the app, critical flows such as startups or ANRs would be difficult or impossible for apps to capture.

To help with this, Android 16 introduces system-triggered profiling to ProfilingManager. Apps can register interest in receiving traces for certain triggers such as cold start reportFullyDrawn or ANRs, and then the system starts and stops a trace on the app's behalf. After the trace completes, the results are delivered to the app's data directory.

Komponen awal di ApplicationStartInfo

ApplicationStartInfo was added in Android 15, allowing an app to see reasons for process start, start type, start times, throttling, and other useful diagnostic data. Android 16 adds getStartComponent() to distinguish what component type triggered the start, which can be helpful for optimizing the startup flow of your app.

Introspeksi tugas yang lebih baik

JobScheduler#getPendingJobReason() API 会返回作业可能处于待处理状态的原因。不过，作业处于待处理状态的原因可能有多种。

在 Android 16 中，我们引入了一个新 API JobScheduler#getPendingJobReasons(int jobId)，该 API 会返回作业处于待处理状态的多种原因，包括开发者设置的显式约束条件和系统设置的隐式约束条件。

我们还引入了 JobScheduler#getPendingJobReasonsHistory(int jobId)，用于返回最新约束条件更改的列表。

我们建议您使用该 API 来调试作业可能无法执行的原因，尤其是在您发现某些任务的成功率降低或某些作业完成延迟存在 bug 时。例如，未能在后台更新微件，或在应用启动之前未能调用预加载作业。

这还有助于您更好地了解某些作业是否因系统定义的约束条件而无法完成，而不是因明确设置的约束条件而无法完成。

Kecepatan refresh adaptif

Adaptive refresh rate (ARR), introduced in Android 15, enables the display refresh rate on supported hardware to adapt to the content frame rate using discrete VSync steps. This reduces power consumption while eliminating the need for potentially jank-inducing mode-switching.

Android 16 introduces hasArrSupport() and getSuggestedFrameRate(int) while restoring getSupportedRefreshRates() to make it easier for your apps to take advantage of ARR. RecyclerView 1.4 internally supports ARR when it is settling from a fling or smooth scroll, and we're continuing our work to add ARR support into more Jetpack libraries. This frame rate article covers many of the APIs you can use to set the frame rate so that your app can directly use ARR.

API ruang kosong di ADPF

The SystemHealthManager introduces the getCpuHeadroom and getGpuHeadroom APIs, designed to provide games and resource-intensive apps with estimates of available CPU and GPU resources. These methods offer a way for you to gauge how your app or game can best improve system health, particularly when used in conjunction with other Android Dynamic Performance Framework (ADPF) APIs that detect thermal throttling.

By using CpuHeadroomParams and GpuHeadroomParams on supported devices, you can customize the time window used to compute the headroom and select between average or minimum resource availability. This can help you reduce your CPU or GPU resource usage accordingly, leading to better user experiences and improved battery life.

Aksesibilitas

Android 16 menambahkan API dan fitur aksesibilitas baru yang dapat membantu Anda menghadirkan aplikasi kepada setiap pengguna.

API aksesibilitas yang ditingkatkan

Android 16 adds additional APIs to enhance UI semantics that help improve consistency for users that rely on accessibility services, such as TalkBack.

Outline text for maximum text contrast

Users with low vision often have reduced contrast sensitivity, making it challenging to distinguish objects from their backgrounds. To help these users, Android 16 introduces outline text, replacing high contrast text, which draws a larger contrasting area around text to greatly improve legibility.

Android 16 contains new AccessibilityManager APIs to let your apps check or register a listener to see if this mode is enabled. This is primarily for UI Toolkits like Compose to offer a similar visual experience. If you maintain a UI Toolkit library or your app performs custom text rendering that bypasses the android.text.Layout class then you can use this to know when outline text is enabled.

Duration added to TtsSpan

Android 16 extends TtsSpan with a TYPE_DURATION, consisting of ARG_HOURS, ARG_MINUTES, and ARG_SECONDS. This lets you directly annotate time duration, ensuring accurate and consistent text-to-speech output with services like TalkBack.

Support elements with multiple labels

Android currently allows UI elements to derive their accessibility label from another, and now offers the ability for multiple labels to be associated, a common scenario in web content. By introducing a list-based API within AccessibilityNodeInfo, Android can directly support these multi-label relationships. As part of this change, we've deprecated AccessibilityNodeInfo#setLabeledBy and #getLabeledBy in favor of #addLabeledBy, #removeLabeledBy, and #getLabeledByList.

Improved support for expandable elements

Android 16 adds accessibility APIs that allow you to convey the expanded or collapsed state of interactive elements, such as menus and expandable lists. By setting the expanded state using setExpandedState and dispatching TYPE_WINDOW_CONTENT_CHANGED AccessibilityEvents with a CONTENT_CHANGE_TYPE_EXPANDED content change type, you can ensure that screen readers like TalkBack announce state changes, providing a more intuitive and inclusive user experience.

Indeterminate ProgressBars

Android 16 adds RANGE_TYPE_INDETERMINATE, giving a way for you to expose RangeInfo for both determinate and indeterminate ProgressBar widgets, allowing services like TalkBack to more consistently provide feedback for progress indicators.

Tri-state CheckBox

The new AccessibilityNodeInfo getChecked and setChecked(int) methods in Android 16 now support a "partially checked" state in addition to "checked" and "unchecked." This replaces the deprecated boolean isChecked and setChecked(boolean).

Supplemental descriptions

When an accessibility service describes a ViewGroup, it combines content labels from its child views. If you provide a contentDescription for the ViewGroup, accessibility services assume you are also overriding the description of non-focusable child views. This can be problematic if you want to label things like a drop-down (for example, "Font Family") while preserving the current selection for accessibility (for example, "Roboto"). Android 16 adds setSupplementalDescription so you can provide text that provides information about a ViewGroup without overriding information from its children.

Required form fields

Android 16 adds setFieldRequired to AccessibilityNodeInfo so apps can tell an accessibility service that input to a form field is required. This is an important scenario for users filling out many types of forms, even things as simple as a required terms and conditions checkbox, helping users to consistently identify and quickly navigate between required fields.

Ponsel sebagai input mikrofon untuk panggilan suara dengan alat bantu dengar LEA

Android 16 adds the capability for users of LE Audio hearing aids to switch between the built-in microphones on the hearing aids and the microphone on their phone for voice calls. This can be helpful in noisy environments or other situations where the hearing aid's microphones might not perform well.

Kontrol volume sekitar untuk alat bantu dengar LEA

Android 16 adds the capability for users of LE Audio hearing aids to adjust the volume of ambient sound that is picked up by the hearing aid's microphones. This can be helpful in situations where background noise is too loud or too quiet.

Kamera

Android 16 meningkatkan dukungan untuk pengguna kamera profesional, sehingga memungkinkan eksposur otomatis hybrid bersama dengan penyesuaian suhu warna dan tint yang akurat. Indikator mode malam baru membantu aplikasi Anda mengetahui kapan harus beralih ke dan dari sesi kamera mode malam. Tindakan Intent baru mempermudah pengambilan foto bergerak, dan kami terus meningkatkan kualitas gambar UltraHDR dengan dukungan untuk encoding HEIC dan parameter baru dari draf standar ISO 21496-1.

Eksposur otomatis hybrid

Android 16 adds new hybrid auto-exposure modes to Camera2, allowing you to manually control specific aspects of exposure while letting the auto-exposure (AE) algorithm handle the rest. You can control ISO + AE, and exposure time + AE, providing greater flexibility compared to the current approach where you either have full manual control or rely entirely on auto-exposure.

fun setISOPriority() {
    // ... (Your existing code before the snippet) ...

    val availablePriorityModes = mStaticInfo.characteristics.get(
        CameraCharacteristics.CONTROL_AE_AVAILABLE_PRIORITY_MODES
    )

    // ... (Your existing code between the snippets) ...

    // Turn on AE mode to set priority mode
    reqBuilder.set(
        CaptureRequest.CONTROL_AE_MODE,
        CameraMetadata.CONTROL_AE_MODE_ON
    )
    reqBuilder.set(
        CaptureRequest.CONTROL_AE_PRIORITY_MODE,
        CameraMetadata.CONTROL_AE_PRIORITY_MODE_SENSOR_SENSITIVITY_PRIORITY
    )
    reqBuilder.set(
        CaptureRequest.SENSOR_SENSITIVITY,
        TEST_SENSITIVITY_VALUE
    )
    val request: CaptureRequest = reqBuilder.build()

    // ... (Your existing code after the snippet) ...
}

Penyesuaian tint dan color temperature yang presisi

Android 16 adds camera support for fine color temperature and tint adjustments to better support professional video recording applications. In previous Android versions, you could control white balance settings through CONTROL_AWB_MODE, which contains options limited to a preset list, such as Incandescent, Cloudy, and Twilight. The COLOR_CORRECTION_MODE_CCT enables the use of COLOR_CORRECTION_COLOR_TEMPERATURE and COLOR_CORRECTION_COLOR_TINT for precise adjustments of white balance based on the correlated color temperature.

fun setCCT() {
    // ... (Your existing code before this point) ...

    val colorTemperatureRange: Range<Int> =
        mStaticInfo.characteristics[CameraCharacteristics.COLOR_CORRECTION_COLOR_TEMPERATURE_RANGE]

    // Set to manual mode to enable CCT mode
    reqBuilder[CaptureRequest.CONTROL_AWB_MODE] = CameraMetadata.CONTROL_AWB_MODE_OFF
    reqBuilder[CaptureRequest.COLOR_CORRECTION_MODE] = CameraMetadata.COLOR_CORRECTION_MODE_CCT
    reqBuilder[CaptureRequest.COLOR_CORRECTION_COLOR_TEMPERATURE] = 5000
    reqBuilder[CaptureRequest.COLOR_CORRECTION_COLOR_TINT] = 30

    val request: CaptureRequest = reqBuilder.build()

    // ... (Your existing code after this point) ...
}

The following examples show how a photo would look after applying different color temperature and tint adjustments:

Deteksi adegan mode malam kamera

To help your app know when to switch to and from a night mode camera session, Android 16 adds EXTENSION_NIGHT_MODE_INDICATOR. If supported, it's available in the CaptureResult within Camera2.

This is the API we briefly mentioned as coming soon in the How Instagram enabled users to take stunning low light photos blog post. That post is a practical guide on how to implement night mode together with a case study that links higher-quality in-app night mode photos with an increase in the number of photos shared from the in-app camera.

Tindakan intent pengambilan foto motion

Android 16 adds standard Intent actions — ACTION_MOTION_PHOTO_CAPTURE, and ACTION_MOTION_PHOTO_CAPTURE_SECURE — which request that the camera application capture a motion photo and return it.

You must either pass an extra EXTRA_OUTPUT to control where the image will be written, or a Uri through Intent.setClipData(ClipData). If you don't set a ClipData, it will be copied there for you when calling Context.startActivity(Intent).

Peningkatan gambar UltraHDR

Android 16 continues our work to deliver dazzling image quality with UltraHDR images. It adds support for UltraHDR images in the HEIC file format. These images will get ImageFormat type HEIC_ULTRAHDR and will contain an embedded gainmap similar to the existing UltraHDR JPEG format. We're working on AVIF support for UltraHDR as well, so stay tuned.

In addition, Android 16 implements additional parameters in UltraHDR from the ISO 21496-1 draft standard, including the ability to get and set the colorspace that gainmap math should be applied in, as well as support for HDR encoded base images with SDR gainmaps.

Grafik

Android 16 menyertakan peningkatan grafis terbaru, seperti efek grafis kustom dengan AGSL.

Efek grafis kustom dengan AGSL

Android 16 adds RuntimeColorFilter and RuntimeXfermode, allowing you to author complex effects like Threshold, Sepia, and Hue Saturation and apply them to draw calls. Since Android 13, you've been able to use AGSL to create custom RuntimeShaders that extend Shader. The new API mirrors this, adding an AGSL-powered RuntimeColorFilter that extends ColorFilter, and a Xfermode effect that lets you implement AGSL-based custom compositing and blending between source and destination pixels.

private val thresholdEffectString = """
    uniform half threshold;

    half4 main(half4 c) {
        half luminosity = dot(c.rgb, half3(0.2126, 0.7152, 0.0722));
        half bw = step(threshold, luminosity);
        return bw.xxx1 * c.a;
    }"""

fun setCustomColorFilter(paint: Paint) {
   val filter = RuntimeColorFilter(thresholdEffectString)
   filter.setFloatUniform(0.5);
   paint.colorFilter = filter
}

Konektivitas

Android 16 mengupdate platform untuk memberi aplikasi Anda akses ke kemajuan terbaru dalam teknologi nirkabel dan komunikasi.

Pengukuran jarak dengan keamanan yang ditingkatkan

Android 16 menambahkan dukungan untuk fitur keamanan yang andal di lokasi Wi-Fi pada perangkat yang didukung dengan 802.11az Wi-Fi 6, yang memungkinkan aplikasi menggabungkan akurasi yang lebih tinggi, skalabilitas yang lebih besar, dan penjadwalan dinamis protokol dengan peningkatan keamanan termasuk enkripsi berbasis AES-256 dan perlindungan terhadap serangan MITM. Hal ini memungkinkannya digunakan dengan lebih aman dalam kasus penggunaan kedekatan, seperti membuka kunci laptop atau pintu kendaraan. 802.11az terintegrasi dengan standar Wi-Fi 6, yang memanfaatkan infrastruktur dan kemampuannya untuk adopsi yang lebih luas dan deployment yang lebih mudah.

API pengukuran jarak generik

Android 16 menyertakan RangingManager baru, yang menyediakan cara untuk menentukan jarak dan sudut pada hardware yang didukung antara perangkat lokal dan perangkat jarak jauh. RangingManager mendukung penggunaan berbagai teknologi pengukuran jarak seperti sounding saluran BLE, pengukuran jarak berbasis RSSI BLE, Ultra Wideband, dan waktu perjalanan bolak-balik Wi-Fi.

Kehadiran perangkat pengelola perangkat pendamping

Di Android 16, API baru diperkenalkan untuk mengikat layanan aplikasi pendamping Anda. Layanan akan terikat saat BLE berada dalam jangkauan dan Bluetooth terhubung dan layanan akan dibatalkan ikatannya saat BLE berada di luar jangkauan atau Bluetooth terputus. Aplikasi akan menerima callback 'onDevicePresenceEvent()' baru berdasarkan berbagai DevicePresenceEvent. Detail selengkapnya dapat ditemukan di 'startObservingDevicePresence(ObservingDevicePresenceRequest)'.

Media

Android 16 menyertakan berbagai fitur yang meningkatkan pengalaman media.

Peningkatan pemilih foto

The photo picker provides a safe, built-in way for users to grant your app access to selected images and videos from both local and cloud storage, instead of their entire media library. Using a combination of Modular System Components through Google System Updates and Google Play services, it's supported back to Android 4.4 (API level 19). Integration requires just a few lines of code with the associated Android Jetpack library.

Android 16 includes the following improvements to the photo picker:

• Embedded photo picker: New APIs that enable apps to embed the photo picker into their view hierarchy. This allows it to feel like a more integrated part of the app while still leveraging the process isolation that allows users to select media without the app needing overly broad permissions. To maximize compatibility across platform versions and simplify your integration, you'll want to use the forthcoming Android Jetpack library if you want to integrate the embedded photo picker.
• Cloud search in photo picker: New APIs that enable searching from the cloud media provider for the Android photo picker. Search functionality in the photo picker is coming soon.

Video Profesional Lanjutan

Android 16 introduces support for the Advanced Professional Video (APV) codec which is designed to be used for professional level high quality video recording and post production.

The APV codec standard has the following features:

• Perceptually lossless video quality (close to raw video quality)
• Low complexity and high throughput intra-frame-only coding (without pixel domain prediction) to better support editing workflows
• Support for high bit-rate range up to a few Gbps for 2K, 4K and 8K resolution content, enabled by a lightweight entropy coding scheme
• Frame tiling for immersive content and for enabling parallel encoding and decoding
• Support for various chroma sampling formats and bit-depths
• Support for multiple decoding and re-encoding without severe visual quality degradation
• Support multi-view video and auxiliary video like depth, alpha, and preview
• Support for HDR10/10+ and user-defined metadata

A reference implementation of APV is provided through the OpenAPV project. Android 16 will implement support for the APV 422-10 Profile that provides YUV 422 color sampling along with 10-bit encoding and for target bitrates of up to 2Gbps.

Privasi

Android 16 menyertakan berbagai fitur yang membantu developer aplikasi melindungi privasi pengguna.

Update Health Connect

Health Connect 添加了 ACTIVITY_INTENSITY，这是一种根据世界卫生组织关于中等强度和剧烈强度活动的指南定义的数据类型。每个记录都需要提供开始时间、结束时间以及活动强度（中等或剧烈）。

Health Connect 还包含支持医疗记录的更新版 API。这样一来，应用便可在征得用户明确同意的情况下，读取和写入 FHIR 格式的医疗记录。

Privacy Sandbox di Android

Android 16 incorporates the latest version of the Privacy Sandbox on Android, part of our ongoing work to develop technologies where users know their privacy is protected. Our website has more about the Privacy Sandbox on Android developer beta program to help you get started. Check out the SDK Runtime which allows SDKs to run in a dedicated runtime environment separate from the app they are serving, providing stronger safeguards around user data collection and sharing.

Keamanan

Android 16 menyertakan fitur yang membantu Anda meningkatkan keamanan aplikasi dan melindungi data aplikasi Anda.

API berbagi kunci

Android 16 adds APIs that support sharing access to Android Keystore keys with other apps. The new KeyStoreManager class supports granting and revoking access to keys by app uid, and includes an API for apps to access shared keys.

Faktor bentuk perangkat

Android 16 memberikan dukungan bagi aplikasi Anda untuk mendapatkan manfaat maksimal dari faktor bentuk Android.

Framework kualitas gambar dan audio standar untuk TV

The new MediaQuality package in Android 16 exposes a set of standardized APIs for access to audio and picture profiles and hardware-related settings. This allows streaming apps to query profiles and apply them to media dynamically:

• Movies mastered with a wider dynamic range require greater color accuracy to see subtle details in shadows and adjust to ambient light, so a profile that prefers color accuracy over brightness may be appropriate.
• Live sporting events are often mastered with a narrow dynamic range, but are often watched in daylight, so a profile that preferences brightness over color accuracy can give better results.
• Fully interactive content wants minimal processing to reduce latency, and wants higher frame rates, which is why many TV's ship with a game profile.

The API allows apps to switch between profiles and users to enjoy tuning supported TVs to best suit their content.

Internasionalisasi

Android 16 menambahkan fitur dan kemampuan yang melengkapi pengalaman pengguna saat perangkat digunakan dalam bahasa yang berbeda.

Teks vertikal

Android 16 adds low-level support for rendering and measuring text vertically to provide foundational vertical writing support for library developers. This is particularly useful for languages like Japanese that commonly use vertical writing systems. A new flag, VERTICAL_TEXT_FLAG, has been added to the Paint class. When this flag is set using Paint.setFlags, Paint's text measurement APIs will report vertical advances instead of horizontal advances, and Canvas will draw text vertically.

val text = "「春は、曙。」"
Box(
    Modifier.padding(innerPadding).background(Color.White).fillMaxSize().drawWithContent {
        drawIntoCanvas { canvas ->
            val paint = Paint().apply { textSize = 64.sp.toPx() }
            // Draw text vertically
            paint.flags = paint.flags or VERTICAL_TEXT_FLAG
            val height = paint.measureText(text)
            canvas.nativeCanvas.drawText(
                text,
                0,
                text.length,
                size.width / 2,
                (size.height - height) / 2,
                paint
            )
        }
    }
) {}

Penyesuaian sistem pengukuran

Pengguna kini dapat menyesuaikan sistem pengukuran mereka di preferensi regional dalam Setelan. Preferensi pengguna disertakan sebagai bagian dari kode lokalitas, sehingga Anda dapat mendaftarkan BroadcastReceiver di ACTION_LOCALE_CHANGED untuk menangani perubahan konfigurasi lokalitas saat preferensi regional berubah.

Menggunakan formator dapat membantu mencocokkan pengalaman lokal. Misalnya, "0,5 in" dalam bahasa Inggris (Amerika Serikat), adalah "12,7 mm" untuk pengguna yang telah menyetel ponsel ke bahasa Inggris (Denmark) atau yang menggunakan ponsel dalam bahasa Inggris (Amerika Serikat) dengan sistem metrik sebagai preferensi sistem pengukuran.

Untuk menemukan setelan ini, buka aplikasi Setelan, lalu buka Sistem > Bahasa & wilayah.
