Oracle has just released the new Oracle ADF Mobile which allows you to build native applications that will install and run on both iOS and Android devices from the same ADF source code.
Development is done with JDeveloper and ADF and leverages Java and HTML 5 technologies, while keeping the same visual and declarative approach ADF is known for.
You can read more about the Oracle ADF Mobile release here and learn more on its OTN page here.
