So that has been a while.... 1 year and 1 day to be exact. Today I encountered a really weird issue in MAF. Yes, we are still using that in some projects. We are using 2.4.1 to build an app for a company that needs offline storage and sync. As MAF has this incorporated in the framework, and the customer has lots of ADF developers, the choice for MAF was made. Anyway, back to the issue. I was building a new feature and was heavily debugging the app. Next I committed my changes to GIT and pushed them to our GIT server. My stuff was working great :-) Couple of hours later I was getting complaints that people were not able to run the app that was built from the latest version in GIT.... The app started, but hung on the splash screen..... It took me a while to figure out what was happening, and only after analysing the log very carefully I found a possible cause. So I figured that the Debug mode could be the cause of the app hanging. I checked my maf.properties file, and ther...

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 ...

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...
