Getting Started Designing Mobile Applications

Have you ever thought you would like to travel when you retire and live the life of a vagabond. You would not just put wheels on your current house to make it mobile.

You would design a home that would be smaller, have just the essentials you need, could be moved easily,  be efficient and look attractive.  So you should not just convert your web applications to a mobile platform.  In the Oracle  12 (Core). Mobile UI Design Strategies training video, 10 guidelines are discussed that can make your mobile application successful for you and your customers. They are:

1.  Know your user

2. Define essential mobile tasks

3. Design for context

4. Flatten the navigation model

5. Design for the two-minutes task

6. Visual Design

7. Integrate analytics

8. Simplify search

9. Embed collaboration

10. Leverage the mobile platform


Watch the 30 min short video for a discussion on these guidelines.

MAF and Mobile ADF Support Policy

Three documents about MAF and Mobile ADF  Support policy.

1. Mobile Application Framework (MAF) Support Policy (Doc ID 1994853.1)
2. Error Correction End Dates for Mobile Application Framework (MAF) (Doc ID 1994878.1)
3. Mobile Applications Support Policy (Doc ID 1994854.1)


In the first Note, it is interesting to know that fixes will not be provided for versions superseded by a newer release within the same "major version".  Error corrections, or patches, of Oracle Mobile Application Framework are offered against the current version and the latest Minor Version of the previous Major Version.  This allows the customer to stay on a Major Version if needed, while still being able to receive patches and fixes for Mobile Application Framework.  The following illustrates the Error Correction Policy:


Example of Error Correction Policy

In the example above, the current version is 2.1.1.  The latest Minor Version of the previous Major Version is 2.0.2.   Therefore, patches can be requested and delivered against both 2.1.1 and 2.0.2 version.  As 2.1.2 exists, then no fixes for 2.1.0, 2.1.1.

In order to keep up with O/S supportability, continuously check the policy on new O/S versions and the requirement to upgrade to the newer version.  New versions of Mobile Operating System and devices are certified against the most current version of the Mobile Application Framework only.


The second note shows how different the policy is to what we are used to for JDeveloper (Doc ID 401694.1): Once a new release is available, previous releases within the same major version are no longer within the grace period. When 2.1.1 version is released then, 2.1.0 is automatically beyond the error correction date.


The third Note is related to all Oracle Mobile Applications, not specific for MAF.

Mobile application updates will be provided based on the most current release.  Updates will be provided for the current version of the mobile application if the operating system, hardware on which it is running, and the underlying technology on which the application was based, are still covered and entitled to error correction by the associated 3rd party vendor(s).

Finding "End of Support" Information for Oracle Application Development Tools

When does support end for my version of  JDeveloper,  ADF, Netbeans and etc?  It's such a simple question and frequently asked.  There is more to the answer than you might expect, and finding the full detail can be challenging.

This article will describe the navigation path through the relevant documents - all of which need to be read not only to obtain the "end of support" dates, but to also gain an understanding of Oracle Lifetime Support and Error Correction (bug fixing) policies.

The starting point is the Oracle Lifetime Support page

http://www.oracle.com/us/support/lifetime-support/index.html

This page lays out the Oracle Lifetime Support terms, definitions and benefits. Once these are understood, go to the product specific Lifetime Support documents listed on the page. The direct link to the Fusion Middleware document is:

http://www.oracle.com/us/support/library/lifetime-support-middleware-069163.pdf

This is a weighty tome (60 + pages) which contains the actual "end of support" dates. The challenge is to pick out the dates for the different Middleware products which form your chosen technology stack / solution. On page 9, there is a table labeled - "Oracle Application Development Tools". 

Screenshot of rows in Oracle Application Development tools Table on Page 9

Some tables have footnotes that contain

"... For specific dates refer to the respective sections in this document. To find a section, refer to the Table of Contents."

Therefore, be prepared to jump to different sections to find the dates which are specific to the products you have chosen for your Middleware solution.

There is one other very important footnote on some tables, to quote:

"For more-detailed information on bug fix and patch release policies, please refer to the “Error Correction Support Policy” on My Oracle Support ."

This statement leads you down the path to find "Error Correction Support" dates for given patch set version numbers. Establishing the "Error Correction Support" dates for your solution is key because it will inform your plans for patching / maintenance. 

For Some Fusion Middleware Products, you can cut to the chase and go straight to:

Error Correction Support Dates for Oracle Fusion Middleware 11g (11.1.1/11.1.2) [ID 1290894.1]

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.
