As the user selects a word already entered, the keyboard displays suggestions that the user can choose from, to replace the selection.

Additionally, support for the platform's SIP and internet calling features on specific devices is determined by their manufacturers and associated carriers. An NFC Reader application lets the user read and interact with near-field communication NFC tags.

For more information about specifying the API level your app requires, read Supporting Different Platform Versions. Developers Design Download games android 2.3 Distribute Play Console.

Download games android 2.3 can mix multiple audio effects in a local track or apply effects globally, across multiple tracks. The platform now offers built-in support for the VP8 open video compression format and the WebM open container format.

For example, a game application could use readings from a gyroscope and accelerometer on the device to recognize complex user gestures and motions, such as tilt, spin, thrust, and slice. The platform provides a software implementation of Khronos OpenSL ESa standard API that gives applications access to powerful audio controls and effects from native code. Applications can use the API to manage audio devices download games android 2.3 control audio input, output, and processing directly from native code.

Starting from Android 2. A new audio effects API lets developers easily create rich audio environments by adding equalization, bass boost, headphone virtualization widened soundstageand reverb to audio download games android 2.3 and sounds.

Pressing on a word enters a free-selection mode — the user can adjust the selection area as needed by dragging a set of bounding arrows to new positions, then copy the bounded area by pressing anywhere in the selection area. For text entry, the user can slide-press to enter a cursor mode, then reposition the cursor easily and accurately by dragging the cursor arrow. With both the selection and cursor modes, no use of a trackball is needed. The Android system takes a more active role in managing apps that are keeping the device awake for too long or that are consuming CPU while running in the background.

By managing such apps — closing them if appropriate — the system helps ensure best possible performance and maximum battery life.

There is no longer a limit on the size of compressed. Additionally, applications can access a native Storage Manager API to work directly with OBB files downloaded and managed by the system. Note that although platform support for OBB is available in Android 2. Robust native development environment. The Android NDK r5 or higher provides a complete set of tools, toolchains, and libraries for developing applications that use the rich native environment offered by the Android 2.
