As part of Android 9 Google is modernizing the foundations of Android and the apps that run on it, as part of Google’s deep, sustained investments in security, performance, and stability. The API offers several advantages over BitmapFactory, including support for exact scaling, single-step decoding to hardware memory, support for post-processing in decode, and decoding of animated images. In line with that, if your app targets a platform earlier than Android 4.
Google also added APIs for display-based flash support and access to OIS timestamps for app-level image stabilization and special effects. JobScheduler then manages work according to the network status.Knowing the distance to 3 or more APs, you can calculate the device position with an accuracy of 1 to 2 metres. With platform support on Android 9 devices, it&China wholesale two color injection molding machine39;s easy to send and utilize HEIF images from your backend server.Android 9 adds built-in support for HDR VP9 Profile 2, so you can now deliver HDR-enabled movies to your users on HDR-capable devices. With this accuracy you can support use-cases like in-building navigation; fine-grained location-based services such as disambiguated voice control (e. This lets you ensure a great experience for Android 9 users while you work on enhancing your app with Android 9 APIs and targeting.Google has added HEIF (heic) image encoding to the platform.11mc Wi-Fi protocol -- also known as Wi-Fi Round-Trip-Time (RTT). For example, you can improve the sound of someone who speaks quietly in a loud, distant or otherwise acoustically challenging environment. Jobs can now declare their estimated data size, signal prefetching, and specify detailed network requirements—carriers can report networks as being congested or unmetered. HEIF is a popular format for photos that improves compression to save on storage and network data. For example, when a network is congested, JobScheduler might defer large network requests. On supported devices, apps can use the OMAPI API to access secure elements (SE) to enable smart-card payments and other secure services.
The device doesn't need to connect to the APs to use RTT, and to maintain privacy, only the phone is able to determine the distance, not the APs. 'Turn on this light'); and location-based information (e.An ImageDecoder API gives you an easier way to decode images to bitmaps or drawables. A hardware abstraction layer (HAL) provides the underlying API for enumerating the variety of Secure Elements (eSE, UICC, and others) available. You can get all of the latest Kotlin performance improvements just by keeping Android Studio's Kotlin plugin up-to-date.Android 9 lets you build indoor positioning features into your apps through platform support for the IEEE 802.g. Google has expanded ART's use of execution profiles to optimize apps and reduce the in-memory footprint of compiled app code.Google also says to watch for uses of non-SDK interfaces in your app.The Dynamics Processing API lets you use a new audio effect to isolate specific frequencies and lower loud or increase soft sounds to enhance the acoustic quality of your app. Once you've made sure that your app is compatible with this data format for sharing and display, give HEIF a try as an image storage format in your app.After you've made any necessary updates, Google recommends publishing to Google Play right away, without changing the app's platform targeting. And devices that participated in the Beta program from Sony Mobile, Xiaomi, HMD Global, Oppo, Vivo, OnePlus, and Essential, as well as all qualifying Android One devices, will receive this update by the end of this fall.Android # 9 adds an implementation of the GlobalPlatform Open Mobile API to Android. Google has made a commitment to Kotlin in Android and continues to expand support including optimizing the performance of Kotlin code.g. You can create a bitmap or drawable from a byte buffer, file, or URI. Google expects these to correlate closely with reductions in system DEX memory usage and faster startup times for your apps.Other improvements in camera include new Session parameters that help to reduce delays during initial capture and Surface sharing that lets camera clients handle various use-cases without the need to stop and start camera streaming. Google is also working with a number of other partners to launch or upgrade devices to Android 9 this year.Google is also releasing an update to the Android 9 - API 28 SDK, which contains nullability annotations in some of the most frequently used APIs. Android 9 restricts access to selected non-SDK interfaces, so you should reduce your reliance on them. In Android 9, you'll see the first results of this work--we've improved several compiler optimizations, especially those that target loops, to extract better performance.
As you work through the flows, make sure your app runs and looks great, and that it handles the Android 9 behaviour changes properly.With Android 9 coming to Pixel users, and to other devices in the months ahead, it's important to test your app for compatibility as soon as possible. 'Are there special offers for this product?').Starting today, an over-the-air update to Android 9 will begin rolling out to Pixel phones.(Source). ART now uses profile information for an on-device rewriting of DEX files, with reductions up to 11% across a range of popular apps. Google is also continuing to work in partnership with JetBrains to optimize Kotlin's generated code.Google Play will require all app updates to target Android Oreo (targetSdkVersion 26 or higher) by November 2018. Just install your current app from Google Play on a device or emulator running Android 9.Kotlin is a first-class language on Android. The API gives you access to a multi-stage, multi-band dynamics processing effect that includes a pre-equalizer, a multi-band compressor, a post-equalizer and a linked limiter.JobScheduler is Android's central service to help you manage scheduled tasks or work across Doze, App Standby, and Background Limits. On Android 9 devices with hardware support, location permission, and location enabled, your apps can use RTT APIs to measure the distance to nearby Wi-Fi Access Points (APs). When unmetered, it can run prefetch jobs to improve the user experience, such as prefetching headlines. In Android 9, JobScheduler handles network-related jobs better for the user, coordinating with network status signals provided separately by carriers. You can do a jpeg-to-heic conversion using ImageDecoder or BitmapFactory to obtain a bitmap from jpeg, and you can use HeifWriter in the AndroidX library to write HEIF still images from YUV byte buffer, Surface, or Bitmap.Android 9 brings performance and efficiency improvements to all apps through the ART runtime.2 (API level 17), users installing it will see a warning dialogue after that day
