Release 4.2 provides declarative support for building mobile Web applications. Mobile pages use jQuery Mobile to render content on the vast majority of mobile devices. Each application can include both desktop and mobile user interfaces.
Another new theme introduced, Theme 25, incorporates reponsive design principles. Reponsive design automatically adjusts to the screen dimensions. Such themes work well on desktop, tablet and mobile devices.
Release 4.2 now includes HTML5 charts. Charts can now be rendered as either HTML5 or Flash, where Flash charts have automatic fallback to HTML5 when Flash is not detected.
New item types have been introduced including Slider, HTML5 Date Picker, and Yes/No Flip Toggle Switch. Incorporating such HTML5 attributes as sub-types for Email, Phone, and URL together with Placeholders will allow you to improve your end user experience.
A new "mobile-friendly" calendar template has been introduced along with a new List View calendar option.
Release 4.2 includes a suite of business productivity applications, easily installed with only a few clicks. These solutions can be readily used as production applications to improve business processes and are fully supported by Oracle. Packaged Applications also include a collection of sample applications which demonstrate some of the major features of Oracle Application Express.
RESTful Services in Release 4.2 provides stateless access to data and logic, through the use of SQL and PL/SQL. RESTful Services are accessed through the use of Uniform Resource Identifiers (URIs), defined within Oracle Application Express. Data can be easily served in JSON or CSV format, or additional formats by choosing PL/SQL as the source.
* This feature requires APEX Listener 2.0 or later.
