And with the new Hangouts, you can even share your location and send animated GIFs. Now you can print photos, documents, and web pages from your phone or tablet. From apps like Quickoffice, you can open and save files on Google Drive, other cloud storage services, or your device.
And with quick access to recently used files, it's easier than ever to send the file you were just working on. Create and edit documents, spreadsheets and presentations from your phone or tablet with the newly redesigned Quickoffice. Check them out. Applications that embed web content now use Chrome to render web components accurately and quickly. Android now supports closed captioning and subtitles. If you ever lose your device, you can find or wipe it with the Android Device Manager.
The redesigned Email app has a fresh new look with nested folders, contact photos and better navigation. Your wallpaper now extends through the notification tray and system buttons. And when you change your wallpaper, you can preview just how it will look before you set it. Daytime pictures are vivid with clean shadows, and nighttime photos are sharp with less noise.
On devices with an infrared IR blaster, Android now supports applications for remote control of TVs and other nearby devices. Access your location settings from anywhere with a new tile in Quick Settings. Jump to a specific part of a song or video from your lock screen. Before printing, your app needs to generate a properly paginated PDF version of your content. If your app knows how to draw the content, it can quickly create a PDF for printing.
Most devices running Android 4. A new storage access framework makes it simple for users to browse and open documents, images, and other files across all of their their preferred document storage providers.
A standard, easy-to-use UI lets users browse files and access recents in a consistent way across apps and providers. Box and others have integrated their services into the storage access framework, giving users easy access to their documents from apps across the system. Cloud or local storage services can participate in this ecosystem by implementing a new document provider class that encapsulates their services.
The provider class includes all of the APIs needed to register the provider with the system and manage browsing, reading, and writing documents in the provider. The document provider can give users access to any remote or local data that can be represented as files — from text, photos, and wallpapers to video, audio, and more. If you build a document provider for a cloud or local service, you can deliver it to users as part of your existing Android app. After downloading and installing the app, users will have instant access to your service from any app that participates in the framework.
This can help you gain exposure and user engagement, since users will find your services more easily. You can integrate your client app one time, for all providers, without any vendor-specific code. The storage access framework and system UI for browsing make it easier for users to find and import their data from a wider range of sources. With sensor batching, Android works with the device hardware to collect and deliver sensor events efficiently in batches, rather than individually as they are detected.
This lets the device's application processor remain in a low-power idle state until batches are delivered. You can request batched events from any sensor using a standard event listener, and you can control the interval at which you receive batches. You can also request immediate delivery of events between batch cycles. Sensor batching is ideal for low-power, long-running use-cases such as fitness, location tracking, monitoring, and more.
It can make your app more efficient and it lets you track sensor events continuously — even while the screen is off and the system is asleep. Sensor batching is currently available on Nexus 5, and we're working with our chipset partners to bring it to more devices as soon as possible.
Moves and Runtastic Pedometer are using the hardware step-detector to offer long-running, low-power services. These new sensors are implemented in hardware for low power consumption.
The step detector analyzes accelerometer input to recognize when the user has taken a step, then triggers an event with each step. The step counter tracks the total number of steps since the last device reboot and triggers an event with each change in the step count. Because the logic and sensor management is built into the platform and underlying hardware, you don't need to maintain your own detection algorithms in your app.
Step detector and counter sensors are available on Nexus 5, and we're working with our chipset partners to bring them to new devices as soon as possible.
Along with the new provider and APIs, Android 4. Also, the system now allows only the default app to write message data to the provider, although other apps can read at any time. Apps that are not the user's default can still send messages — the system handles writing those messages to the provider on behalf of the app, so that users can see them in the default app.
The new provider and semantics help to improve the user's experience when multiple messaging apps are installed, and they help you to build new messaging features with fully-supported, forward-compatible APIs. A new immersive mode lets apps use every pixel on the screen to show content and capture touch events. Now your apps can use every pixel on the device screen to showcase your content and capture touch events.
It's ideal for rich visual content such as photos, videos, maps, books, and games. In the new mode, the system UI stays hidden, even while users are interacting with your app or game — you can capture touch events from anywhere across the screen, even areas that would otherwise be occupied by the system bars.
This gives you a great way to create a larger, richer, more immersive UI in your app or game and also reduce visual distraction. To make sure that users always have easy, consistent access to system UI from full-screen immersive mode, Android 4. To return to immersive mode, users can touch the screen outside of the bar bounds or wait for a short period for the bars to auto-hide.
For a consistent user experience, the new gesture also works with previous methods of hiding the status bar. Most apps structure their flows around several key UI states that expose different actions.
Many apps also use animation to help users understand their progress through those states and the actions available in each. To make it easier to create high-quality animations in your app, Android 4. The transitions framework lets you define scenes , typically view hierarchies, and transitions, which describe how to animate or transform the scenes when the user enters or exits them. You can use several predefined transition types to animate your scenes based on specific properties, such as layout bounds, or visibility.
There's also an auto-transition type that automatically fades, moves, and resizes views during a scene change. In addition, you can define custom transitions that animate the properties that matter most to your app, and you can plug in your own animation styles if needed. With the transitions framework you can also animate changes to your UI on the fly , without needing to define scenes.
For example, you can make a series of changes to a view hierarchy and then have the TransitionManager automatically run a delayed transition on those changes. Another change concerns the use of the entire display surface to hide such UI elements as on-screen buttons and the notification bar. The new Android firmware marked some interesting changes in specialized sensors. From now on, the system will be able to receive information from such sensors in batches, which will reduce the processor load of your device and group the data in certain intervals.
This will also reduce battery consumption and allow the implementation of additional sensors like the presence sensor and pedometer. In addition, Android now has built-in support for infrared ports and several Bluetooth profiles.
KitKat is also able to perform wireless printing of all kinds of documents. Android 4. The available filters are similar to those of Instagram.
Other settings are quite standard: cropping, alignment, rotation and mirroring. Now updating and installing the operating system on your smartphone or tablet has become even easier.
You can also install new apps while running the system live. Google Play Store and Aptoide App Manager are pre-installed so you can just make your choices… Read the full changelog. Load comments.
