This document provides a glimpse of what's new for developers.
See the Android 4. Find out more about the new Jelly Bean features for users at www. Faster, Smoother, More Responsive Android 4. For a graphics performance boost, the hardware-accelerated 2D renderer now optimizes the stream of drawing commands, transforming it into a more efficient GPU format by rearranging and merging draw operations.
For multithreaded processing, the renderer can also now use multithreading across multiple CPU cores to perform certain tasks. Shapes such as circles and rounded rectangles are now write ahead logging android games at higher quality in a more efficient manner.
Optimizations for text include increased performance when using multiple fonts or complex glyph sets CJKhigher rendering quality when scaling text, and faster rendering of drop shadows. Improved window buffer allocation results in a faster image buffer allocation for your apps, reducing the time taken to start rendering when you create a window.
For highest-performance graphics, Android 4. Support is already available on Nexus 7Nexus 4, and Nexus 10 devices.
Enhanced Bluetooth Connectivity Connectivity with Bluetooth Smart devices and sensors Now you can design and build apps that interact with the latest generation of small, low-power devices and sensors that use Bluetooth Smart technology.
With the new APIs, your apps can efficiently scan for devices and services of interest. You can connect to a GATT server hosted on the device and read or write characteristics, or register a listener to receive notifications whenever those characteristics change. You can implement support for any GATT profile.
You can read or write standard characteristics or add support for custom characteristics as needed. Your app can function as either client or server and can transmit and receive data in either mode.
Support for Bluetooth Smart Ready is already available on Nexus 7 and Nexus 4 devices and will be supported in a growing number of Android-compatible devices in the months ahead. In addition to exposing playback controls on the remote devices connected over Bluetooth, apps can now transmit metadata such as track name, composer, and other types of media metadata.
Support for Restricted Profiles A tablet owner can set up one or more restricted profiles in Settings and manage them independently. With restricted profiles, tablet owners can quickly set up separate environments for each user, with the ability to manage finer-grained restrictions in the apps that are available in those environments.
Restricted profiles are ideal for friends and family, guest users, kiosks, point-of-sale devices, and more. Each restricted profile offers an isolated and secure space with its own local storage, home screens, widgets, and settings. For developers, restricted profiles offer a new way to deliver more value and control to your users.
You can implement app restrictions — content or capabilities controls that are supported by your app — and advertise them to tablet owners in the profile configuration settings. You can add app restrictions directly to the profile configuration settings using predefined boolean, select, and multi-select types.
If you want more flexibility, you can even launch your own UI from profile configuration settings to offer any type of restriction you want.
When your app runs in a profile, it can check for any restrictions configured by the owner and enforce them appropriately. For example, a media app might offer a restriction to let the owner set a maturity level for the profile.
At run time, the app could check for the maturity setting and then manage content according to the preferred maturity level.Everything you need to know to get started with Android app development.

Android uses a file system that's similar to disk-based file systems on other platforms. This page describes how to work with the Android file system to read and write files with the File APIs.. A File object works well for reading or writing large amounts of data in start-to-finish order without skipping around.
For example, it's good for image files or anything exchanged over a network. It (enableWriteAheadLogging ()) doesn't get called somewhere in greendao, so you have to call it yourself, i.e.
in your implementation of timberdesignmag.comao uses transactions though. There is also some synchronization done inside greendao, but to be sure you should use enableWriteAheadLogging (). Search the world's information, including webpages, images, videos and more.
