Luc Bors Weblog

Yesterday ODTUG organised the ODTUG Mobile Day in Utrecht the Netherlands. The event was supported by two local user groups, OGh and OBUG, and sponsored by eProseed NL. This full-day event was dedicated to Oracle's next-generation mobile development, infrastructure, and security solutions: "Going Mobile? Where is Oracle Taking You?". All of this was presented by the world’s leading ACE Directors and ACEs, Lonneke Dikmans – Oracle ACE Director Dimitri Gielis – Oracle ACE Director Roel Hartman – Oracle ACE Director Mark Rittman – Oracle ACE Director Mia Urman – Oracle ACE Director Luc Bors – Oracle ACE and several Oracle speakers. Session abstract are published at the ODTUG website . These top experts in the field showed how to implement the latest mobile advancements from the newest technologies, such as Oracle Mobile Cloud infrastructure to building BI mobile dashboards to a deep dive into APEX security for mobile to the latest features in Ora...

One of the new features in version 2.1.1. of Oracle MAF are local notifications. These notifications originate within the MAF application and are received by the same application. They are delivered to the end user through standard mechanisms supported by the mobile device platform (for example, banner, sound) and can work when the application is either in the foreground, background or not running at all. I this post I show you an example of how to work with Local Notifications from Java. I use a simple MAF app. I will not explain how to build this app, but the source can be downloaded here. It is mainly derived from the "LocalNotificationDemo" public sample app. Introducing Local Notifications As with many framework features, MAF supports three ways to set Local Notifications. First you can use the device features datacontrol. To support declarative use of Local Notifications, the DeviceFeatures data control includes the addLocalNotification and cancelLocalNotification...

During the closing keynote at the Oracle Fusion Middleware Forum XX in Budapest my former colleague Lucas Jellema and I delivered a live development demo. It was great fun to do. During this demo I developed an Oracle MAF frontend on top of Oracle SOA Suite 12c REST-JSON services. All in all it was a good session that was exactly delivered on-time with no errors. I think the demo gods where with us. In this post I describe some of the details regarding the Oracle MAF part of this demo. To be more specific, how the MAF application is able to work with the REST-JSON Services. In a later post I will go into the details of how to user interface was built. The details of the SOA suite 12c Backend are described by Lucas at the AMIS Technology blog in the following posts: Preparing  , Implementing part - 1   and Implementing part – 2 Before I start with the details I best describe the case first. We decided to create a tablet app that can be used by flight attendants...

Mobile apps usually have the possibility to toggle the springboard by using an icon that is displayed in the header of the app. The Oracle MAF reference app, Work Better, also tries to implement this behavior. The showing of the springboard works fine, however, hiding it does not really work as expected. In this post I show you how to implement a working custom toggle springboard functionality. Default Toggle Springboard Implementation First let's take a look at how the toggle springboard functionality works out of the box. In your application configuration file you need to set the "Show Springboard Toggle Button" to true in order to enable toggle functionality. All the rest is taken care of by the framework at runtime and these setting results in the default toggle springboard icons to show up on both iOS and Android. Note that this of course also works with a custom springboard. An obsolete way to implement Custom Springboard Toggle (you might want to skip ...

Images are heavily used in Mobile apps. For instance a list that contains employees usually shows the images of these employees. This works well when you have a WIFI connection, but what if you are using slower connections ? If you look at a mobile twitter app you will see that, depending on connectivity, images are loaded instantaneously or delayed. In this post I explain how you can load the images of a List in a background process, after the other content has been loaded.

Two weeks ago I visited Oracle Open World in San Francisco. A glimpse of my activity during Oracle Open World can be found in this post. If you want to hear more, please visit the AMIS Oracle Open World Review Session at October 16th. Saturday After a one hour delay at Amsterdam Schiphol Airport the airplane with, amongst others, several AMIS employees took of for San Francisco. There we met with our colleagues who flew in earlier this week.

It has been a while since my previous post, and I have a very good reason for that. I have been busy, very busy. But now, after a long time of writing and rewriting I can finally announce that my book, Oracle Mobile Application Framework Developer Guide, is available for you to buy. Many thanks to my reviewers Chris Muir, Frank Nimphius and Joe Huang who guided and helped me all the way. If you are starting with Oracle MAF development, this book will give you a jump start. You will learn the concepts of MAF and MAF development and learn tips and tricks for MAF development. In Oracle Mobile Application Framework Developer Guide, I explain how to use this powerful framework to create multiplatform mobile apps based on a single code base. Detailed examples and ready-to-use code are provided throughout the book. A complete, step-by-step sample application highlights the robust functionality of Oracle Mobile Application Framework, including data visualization, UX pattern...

Next week the ODTUG KScope conference kicks of in New Orleans. During this conference I will present 3 sessions: June 24th: Goodbye Nightmare: Tips and Tricks for Creating Complex Layouts with Oracle ADF Faces   June 25th: ADF Mobile: Best Practices for Developing Applications with Oracle ADF Mobile  June 26th: Don't Reinvent the Wheel: Tips and Tricks for Reuse in Oracle ADF    Keep your eyes on this weblog for more information on ADF and Mobile stories of ODTUG KScope13.  

Today Oracle published the first in a series of online eLearning training materials. The ADF Academy presents free and online : Developing Applications with ADF Mobile. The main goal is to deliver technical training material to everybody that needs it. You get an online training, where you can view audio and video to learn ADF. Whenever you want to you can stop the recordings to try out everything that you learned so far, or perhaps to get a drink. Developing Applications with ADF Mobile is available here . Take to opportunity and learn to work with a great framework to develop mobile applications for iOS and Adroid. Also keep an eye on lucbors.blogspot.com for more ADF Mobile related content.

One very common pattern in Mobile Apps is the use of "pull" to refresh a list of data in an App. For one of my projects I suggested to use this pattern and I had to figure out a way to implement this in ADF Mobile. In this post I show you a way to implement this. If you are only interested in the refresh part, you might want to skip the first 5 steps. These explain in short the webservice and the basic ADF Mobile app. From step 6 on I explain how to implement the pattern. 1. The webservice For this example I use a simple webservice that returns a List of Locations. The webservice is a service enabled Application Module. I simply created Business Component (EO and VO) on the Locations table from the HR schema. I exposed the Locations view object as AllLocations, and added a method called getCurrentCount() on the Application Module Impl class.  This method simply invokes the getEstimatedRowCount() to find out the number of rows. Next I created a new Service Interface on ...
