API Level: 18
Android 4.3 (JELLY_BEAN_MR2) is an update to the Jelly Bean release that offers new features for users and app developers.
This document provides an introduction to the most notable new APIs. As an app developer, you should download the Android 4.3 system image and SDK platform from the SDK Manager as soon as possible. If you don't have a device running Android 4.3 on which to test your app, use the Android 4.3 system image to test your app on the Android emulator. Then build your apps against the
Android 4.3 platform to begin using the latest APIs. Update your target API level To better optimize your app for devices running Android 4.3, you should set your targetSdkVersion to "18", install it on an Android 4.3 system image, test it, then publish an update with this change. You can use APIs in Android 4.3 while also supporting older versions by adding conditions to your code that check for the system API level before executing APIs not supported by your minSdkVersion. To learn more about maintaining backward compatibility, read Supporting Different Platform Versions. Various APIs are also available in the Android Support Library that allow you to implement new features on older versions of the platform.
