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 menambahkan API baru untuk membantu Anda mengaktifkan animasi sistem kembali prediktif dalam navigasi gestur seperti animasi kembali ke layar utama. Dengan mendaftarkan onBackInvokedCallback ke PRIORITY_SYSTEM_NAVIGATION_OBSERVER baru, aplikasi Anda dapat menerima panggilan onBackInvoked reguler setiap kali sistem menangani navigasi kembali tanpa memengaruhi alur navigasi kembali normal.

Android 16 juga menambahkan finishAndRemoveTaskCallback() dan moveTaskToBackCallback. Dengan mendaftarkan callback ini dengan OnBackInvokedDispatcher, sistem dapat memicu perilaku tertentu dan memutar animasi yang sesuai sebelumnya saat gestur kembali dipanggil.

Haptik yang lebih kaya

Android has exposed control over the haptic actuator ever since its inception.

Android 11 added support for more complex haptic effects that more advanced actuators could support through VibrationEffect.Compositions of device-defined semantic primitives.

Android 16 adds haptic APIs that let apps define the amplitude and frequency curves of a haptic effect while abstracting away differences between device capabilities.

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

Di Android 16, framework wallpaper animasi mendapatkan API konten baru untuk mengatasi tantangan wallpaper dinamis yang didorong pengguna. Saat ini, wallpaper live yang menggabungkan konten yang disediakan pengguna memerlukan penerapan khusus layanan yang kompleks. Android 16 memperkenalkan WallpaperDescription dan WallpaperInstance. WallpaperDescription memungkinkan Anda mengidentifikasi instance wallpaper animasi yang berbeda dari layanan yang sama. Misalnya, wallpaper yang memiliki instance di layar utama dan layar kunci mungkin memiliki konten unik di kedua tempat tersebut. Pemilih wallpaper dan WallpaperManager menggunakan metadata ini untuk menampilkan wallpaper dengan lebih baik kepada pengguna, sehingga menyederhanakan proses bagi Anda untuk membuat pengalaman wallpaper hidup yang beragam dan dipersonalisasi.

Performa dan baterai

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

Pembuatan profil yang dipicu sistem

ProfilingManager ditambahkan di Android 15, yang memberi aplikasi kemampuan untuk meminta pengumpulan data pembuatan profil menggunakan Perfetto di perangkat publik di lapangan. Namun, karena pembuatan profil ini harus dimulai dari aplikasi, alur penting seperti startup atau ANR akan sulit atau tidak dapat direkam oleh aplikasi.

Untuk membantu hal ini, Android 16 memperkenalkan pembuatan profil yang dipicu sistem ke ProfilingManager. Aplikasi dapat mendaftarkan minat untuk menerima rekaman aktivitas untuk pemicu tertentu seperti cold start reportFullyDrawn atau ANR, lalu sistem akan memulai dan menghentikan rekaman aktivitas atas nama aplikasi. Setelah pelacakan selesai, hasilnya akan dikirim ke direktori data aplikasi.

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 menampilkan alasan mengapa tugas mungkin tertunda. Namun, tugas mungkin tertunda karena beberapa alasan.

Di Android 16, kami memperkenalkan API JobScheduler#getPendingJobReasons(int jobId) baru, yang menampilkan beberapa alasan mengapa tugas tertunda, karena batasan eksplisit yang ditetapkan oleh developer dan batasan implisit yang ditetapkan oleh sistem.

Kami juga memperkenalkan JobScheduler#getPendingJobReasonsHistory(int jobId), yang menampilkan daftar perubahan batasan terbaru.

Sebaiknya gunakan API untuk membantu Anda men-debug alasan tugas Anda mungkin tidak dieksekusi, terutama jika Anda melihat penurunan rasio keberhasilan tugas tertentu atau memiliki bug di sekitar latensi penyelesaian tugas tertentu. Misalnya, pembaruan widget di latar belakang gagal terjadi atau tugas pengambilan data gagal dipanggil sebelum aplikasi dimulai.

Hal ini juga dapat membantu Anda lebih memahami apakah tugas tertentu tidak selesai karena batasan yang ditentukan sistem dibandingkan batasan yang ditetapkan secara eksplisit.

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 menambahkan tindakan Intent standar — ACTION_MOTION_PHOTO_CAPTURE, dan ACTION_MOTION_PHOTO_CAPTURE_SECURE — yang meminta aplikasi kamera mengambil foto gerakan dan menampilkannya.

Anda harus meneruskan EXTRA_OUTPUT tambahan untuk mengontrol tempat gambar akan ditulis, atau Uri melalui Intent.setClipData(ClipData). Jika Anda tidak menetapkan ClipData, nilai tersebut akan disalin ke sana untuk Anda saat memanggil Context.startActivity(Intent).

Peningkatan kualitas 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 includes the new RangingManager, which provides ways to determine the distance and angle on supported hardware between the local device and a remote device. RangingManager supports the usage of a variety of ranging technologies such as BLE channel sounding, BLE RSSI-based ranging, Ultra Wideband, and Wi-Fi round trip time.

Kehadiran perangkat pengelola perangkat pendamping

In Android 16, new APIs are being introduced for binding your companion app service. Service will be bound when BLE is in range and Bluetooth is connected and service will be unbound when BLE is out of range or Bluetooth is disconnected. App will receives a new 'onDevicePresenceEvent()' callback based on various of DevicePresenceEvent. More details can be found in '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 memperkenalkan dukungan untuk codec Advanced Professional Video (APV) yang dirancang untuk digunakan dalam proses perekaman dan pascaproduksi video berkualitas tinggi tingkat profesional.

Standar codec APV memiliki fitur berikut:

• Kualitas video yang tidak mengalami kompresi secara persepsi (hampir sama dengan kualitas video mentah)
• Kompleksitas rendah dan coding intra-frame-only throughput tinggi (tanpa prediksi domain piksel) untuk mendukung alur kerja pengeditan dengan lebih baik
• Dukungan untuk rentang kecepatan bit tinggi hingga beberapa Gbps untuk konten resolusi 2K, 4K, dan 8K, yang diaktifkan oleh skema coding entropi ringan
• Pemasangan ubin frame untuk konten imersif dan untuk mengaktifkan encoding dan decoding paralel
• Dukungan untuk berbagai format sampling kromatik dan kedalaman bit
• Dukungan untuk beberapa decoding dan encoding ulang tanpa penurunan kualitas visual yang parah
• Mendukung video multi-tampilan dan video tambahan seperti kedalaman, alfa, dan pratinjau
• Dukungan untuk HDR10/10+ dan metadata yang ditentukan pengguna

Implementasi referensi APV disediakan melalui project OpenAPV. Android 16 akan menerapkan dukungan untuk Profil APV 422-10 yang menyediakan sampling warna YUV 422 bersama dengan encoding 10-bit dan untuk target kecepatan bit hingga 2 Gbps.

Privasi

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

Update Health Connect

Health Connect adds ACTIVITY_INTENSITY, a data type defined according to World Health Organization guidelines around moderate and vigorous activity. Each record requires the start time, the end time, and whether the activity intensity is moderate or vigorous.

Health Connect also contains updated APIs supporting medical records. This allows apps to read and write medical records in FHIR format with explicit user consent.

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.
