Oracle Mobile Application Framework 2.1

The new Oracle Mobile Application Framework 2.1 is now available. This new version focuses on upgrading the framework's infrastructure and includes the following new features:

Support for Java 8 - Java is the language used for business logic development on Oracle MAF, in fact Oracle MAF is the only solution out there that will run the same Java code on both iOS and Android. Now developers can leverage the latest features of the Java language - such as Lambda expressions, Collections with Generics and more - while running on a 64bit JVM that supports the Java 8 Compact2 profile.

Cordova 3 support - Cordova is used in Oracle MAF to provide access to device features. Oracle MAF 2.1 updates the Cordova version to 3.6.3 on Android and 3.7 for iOS, dramatically increasing the number of available plugins that developers can leverage.

Simpler Cordova Plugin integration - Oracle MAF leverages the plugman command line to build and incorporate plugins into Oracle MAF apps.

Xcode 6 and Android 5 support - use the latest SDKs to compile and deploy your MAF applications across multiple devices.

You can get Oracle MAF 2.1 by downloading the new Oracle MAF extension through the JDeveloper Help->Check for Updates functionality.

See Announcing Oracle Mobile Application Framework 2.1 - Now Available for more information.
