Update 3/20/2014: Added notes for b54 drop.

As announced 2 weeks ago, we have started semi-regular developer drops of Java ME 8.

Developer Drop b54 was just pushed out today. As before, this is provided “as is”, with no guarantees of stability or functionality. 

To access, go to the EA #2 downloads page and look for “latest developer build”:

Note: It is recommended to use the NetBeans 8 RC1 or NetBeans 8 GA “All” bundle together with the latest Java ME SDK 8 developer build.


Change of Device Access API in the b54:

  • The Device Access API name and namespace has been changed to Device I/O (DIO) in preparation for the Java ME 8 final release. This requires that you update the package imports in your application. The latest DIO documentation can be found here.

Notes on changes for the Qualcomm IoE platform in b54:

  • The previously separate Netsetup BrewMP application has been removed and the functionality has been integrated into the Java runtime. Network setup for WiFi/3G is now done as part of the Java runtime initialization.
  • A new BrewMP application called reboot_java has been added. It is optional and can be used to trigger a soft reboot (Java reboot without board reboot).
  • Network setup, AccessPoint API, and Cellular API functionality has been improved/made more complete.

MOOC video

The free Massive Open Online Course (MOOC) “Develop Java ME 8 Embedded Applications with Raspberry Pi” will kick off March 31 (original announcement here)

Space is filling up fast (we’re capping registration numbers to allow for good student/instructor ratio). This is going to be a very cool course, and the MOOC team just released a new video describing the outline and the goals.

Announcing Java ME 8 Developer Drops

Recently, we released Early Access #2 versions of Java ME 8 and Java ME SDK 8. A lot of developers tried it out and feedback has been great. As expected (after all, this was an Early Access release) – there are still bugs and deficiencies and we have been busy fixing them … many are already taken care of.

In order to enable the developer community to follow along and benefit from the latest improvements and fixes we decided to provide semi-regular developer drops alongside the Early Access #2 release. These developer drops are planned roughly every 14 days, are based on the latest builds and have undergone basic testing. They are provided “as is”, with no guarantees of stability or functionality. This is bleeding edge ;-)

 You can access these developer builds on the same pages as the other EA #2 downloads (look for “latest developer build”):

Note: It is recommended to use the NetBeans 8 RC1 “All” bundle together with the latest Java ME SDK 8 developer build.


Please go ahead and give the latest developer builds a spin. And be sure to ask questions and provide feedback: Java ME Embedded OTN forum or

Info header kurz ENG

As in last years, Oracle will again have a big presence at Embedded World in Nuremberg, Germany

Find us in hall 5, booth 271. At the booth, you can see several demos focusing on Oracle’s Internet of Things strategy and the benefits of Java for embedded software solutions, including showcase applications by partners such as Gemalto, Freescale, Eurotech, and Hitachi.

I will be doing some sessions as well (download the full conference program here):

  • Thu, Feb 27, 9:30: A hands-on tutorial on “Desktop to Internet of Things in 12 Seconds with Java ME Embedded”
  • Thu, Feb 27, 15:30: “Trust Me, I am an M2M Device”

Java cup

So, pick up some Java while you’re at Embedded World, and not just the technology kind, but also the hot, coffee kind ;-) 

See you at Embedded World!

Android lock in

Google is moving quickly to further lock down the Android ecosystem (as already reported in part 1 and part 2). 

Yesterday, cyanogenmod was forced by Google to remove the CyanogenMod Installer from the Google Play Store, citing that it ‘encourages users to void their warranty’.  However, if you know that cyanogenmod is working with hardware manufacturers to preinstall CyanogenMod to create alternate Android devices then Googles demand appears in a very different light.

I expect the next step for Google is to start locking down side-loading as well (installing apps through alternate channels) to further tighten control.

The air for embedded Android is getting thinner.

Android lock in

A few weeks ago I blogged about an ars technica article which looked at Google’s increasing control over the Android ecosystem (“Android “open for embedded”? Must-read Ars Technica article”).

Yesterday, Vision Mobile published a related post “The Naked Android” which keenly describes the role of Google Play Services and how Google is driving towards its Android endgame of “flatten, expand, mine”. 

More food for thought if you’re considering Android for embedded.

Android lock in

Update (Nov 20): See also part 2 of this post.

A few days ago ars technica published an article “Google’s iron grip on Android: Controlling open source by any means necessary”.

If you are considering Android for embedded this article is a must-read to understand the severe ramifications of Google’s tight (and tightening) control on the Android technology and ecosystem.

Some quotes from the ars technica article:

  • “Android is open – except for all the good parts
  • “Android actually falls into two categories: the open parts from the Android Open Source Project (AOSP) … and the closed source parts, which are all the Google-branded apps”
  • “Android open source apps … turn into abandonware by moving all continuing development to a closed source model.”
  • “Joining the OHA requires a company to sign its life away and promise to not build a device that runs a competing Android fork.”
  • “Google Play Services is a closed source app owned by Google … to turn the “Android App Ecosystem” into the “Google Play Ecosystem”
  • “You’re allowed to contribute to Android and allowed to use it for little hobbies, but in nearly every area, the deck is stacked against anyone trying to use Android without Google’s blessing

Compare this with a recent Wired article “Oracle Makes Java More Relevant Than Ever”:

“Oracle has actually opened up Java even more — getting rid of some of the closed-door machinations that used to be part of the Java standards-making process. Java has been raked over the coals for security problems over the past few years, but Oracle has kept regular updates coming. And it’s working on a major upgrade to Java, due early next year.”

ME 8 webcast screenshot

Update (9/25): Some users may be experiencing problems when installing the Java ME SDK 8 EA plugins into NetBeans. Please see the updated Java ME SDK 8 EA Release Notes for a workaround.

As I blogged recently, the Java ME 8 specifications are moving full steam ahead. And today, Oracle is announcing the immediate availability of Java ME 8 Early Access.

Java ME 8 in a Nutshell:

Java ME 8 is a significant update of the Java ME platform and provides a modern, flexible, and feature-rich embedded software platform that is aligned with Java SE 8 and allows more efficient development, deployment, and management of embedded software solutions:

Java ME 8 Early Access scales down to very small target devices – the single-chip solution used on the STM32F4DISCOVERY board has 192 KB of RAM and 1 MB Flash, and costs around US $5 in volume, yet can host a complete solution of Java ME 8 EA runtime, networking and device access functionality, and Java application.

With this update, Java ME 8 is positioned to be the platform of choice for intelligent devices and the Internet of Things.

To learn more about Java ME 8:

Getting started with Java ME 8 Early Access:

Java ME 8 Early Access is available now for the following developer boards:

  • Raspberry Pi Model B (ARM11/Linux)
  • ST Microelectronics STM32F4DISCOVERY (ARM Cortex-M4)

Software development is supported by the Java ME SDK 8 Early Access, which includes a Java ME 8 runtime emulation on Windows as well (so you can get started even without a developer board).

  • Learn more and download Java ME 8 Early Access binaries and Java ME SDK 8 Early Access tools
  • Access Release Notes and step-by-step Getting Started Guides
