Android 4.0 Source Code is Now Available

Google has just released Android 4.0.1 source code in AOSP. There are 3 main branches: android-4.0.1_r1: the release branch, ITL41D, that is expected to ship on Galaxy Nexus. That’s the one you want to be using to port to devices. ics-mr0: ICS development branch. It contains a few changes that aren’t in the release branch, so it might not be as stable. That’s the one you want to use if you plan to contribute to CTS. master: usual master branch, it contains all of ics-mr0 plus a few extra changes. That’s the branch that you should use if you want to contribute to the platform. The release and development branch require the “classic” host configurations (Ubuntu 10.04, or MacOS 10.6 with XCode 3). The master branch had a few tweaks to make it work better on newer systems  (Ubuntu 11.10, Mac OS 10.7 with XCode 4.2) but it’s not 100% there yet. In addition to the usual emulator targets and …

Linaro’s Android Platform – ELCE 2011

Zach Pfeffer, Linaro Android Platform team leader, describes Linaro’s work on the Android platform and future plans at Embedded Linux Conference Europe 2011. Abstract: Linaro uses components from the Android Open Source Project, member companies, community supported efforts and Linaro engineering teams to build integrated, easy-to-use and well tested Android platforms for upstream work, product baselines and hobby projects. The team currently has platforms for TIs PandaBoard, BeagleBoard and Beagle xM, ST Ericsson’s Snowball, Samsung’s Origen and Freescale’s iMX53. They recently released platforms with Android 2.3.4 built against GCC 4.6 and running the 3.0 Linux kernel. In this session Zach reviews what’s been done, the Linaro Android concept, how Linaro brings Android together and what their plans are. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011. http://www.cnx-software.com Support CNX Software – Donate via PayPal …

Build Community Android Distribution and Ensure the Quality – ELCE 2011

Jim Huang, developer and co-founder of 0xlab, explains how they built an Android distribution with Linaro at Embedded Linux Conference Europe 2011. Abstract: While developing Android distributions, 0xdroid and LEB (Linaro Evaluation Build), we learn much about the development approach to non-traditional open source software model such as Android Open Source Project. This session shares the experience how 0xlab established the community, contributes to upstream (in unusual way), and leveraged the strong efforts from Linaro. Also, 0xlab develops a serial of open source projects to ensure overall performance and quality for better user experience.
