Explaining the software upgrade process and its improvements for Android™ 4.3

Yesterday was a big day for all Android fans, as Google released the source code for Android 4.3. This means that manufacturers now are getting busy preparing software upgrades. From Sony’s side, you can already read about some of our software upgrade plans on the Sony Xperia News room blog. Software upgrades are an important asset for a device, and we are continuously working to improve the process and lead times. Learn more about how the process works, and what improvements you will see going forward in the full post. Read more after the jump!

Explaining the software upgrade process and its improvements for Android™ 4.3

Jelly Bean available for custom ROM developers [alpha ROM]

A while ago, the Sony Xperia™ News room shared an update on our plans to upgrade certain Xperia™ devices to Jelly Bean. Since then we have received quite a few requests from the Android™ developer community to release an earlier version of the Jelly Bean (JB) software for the developers. This way, advanced developers could try it out and evaluate it, in a similar way to how we did it last year with the ICS alpha release. Please note that there are several limitations to this alpha software, for instance the UI look and feel is not updated to final Sony Jelly Bean software. Read more after the jump!

Sony release binaries to support JBQ’s Vanilla Android Xperia™ S project [download]

Sony opens up the Dynamic Android Sensor HAL (DASH) – developers can contribute [open source]

We are now releasing a sensor framework, referred to as DASH (Dynamic Android Sensor HAL), as an open source GitHub project. This actually means that we are the first manufacturer to release such a sensor framework. By making this open source, we hope that custom ROM developers will gain a lot from using it, and we also hope to see the community of developers help us improve the framework by contributing back (which we’ve already seen from CyanogenMod team). In this article, Oskar Anderö, a Sony Mobile software engineer, explains how DASH works, and how developers can contribute.

Stepping up our open source activities

As part of our continuing efforts towards openness and knowledge sharing, we are now stepping up our open source activities. For a long time, we have been one of the major contributors to the Android Open Source Project. We’ve also been active in the open developer community where we most notably published an ICS alpha release a couple of months ago. And now, we’re excited to release a couple of new open source projects that are available on our GitHub. As you can see below, we have just now released two very interesting projects as open source: the analysis tool ChkBugReport, and our WebGL implementation for Android™ 4.0.

This way, we would like to continue to be transparent, share our knowledge, and get external developer contributions to make the tools even better. On our GitHub, you can also find our Web SDK  project we published a while back, and a project called DrmLicenseService, which we will tell more about soon. Stay tuned for more information about open source projects going forward!

Thanks for the feedback!

Last week we made an Ice Cream Sandwich alpha ROM available for unlocked Xperia™ phones. The response we got was overwhelming, and we want to say a big thank you for all your great feedback and the huge interest shown! We will look through all the comments we received in the survey, on the blog post and on the video, and incorporate the input into our planning of future software and product releases. We have now also made the open source archive for the Ice Cream Sandwich alpha ROM available. In addition, the sensor HAL will also be available as open source soon.
