Android L x86 64-bit Developer Preview Emulator Image Released

Several weeks ago Linaro posted instructions to run Android L ARM 64-bit in QEMU which takes some efforts to setup, and at the time lacked OpenGL support (not sure about the status now). Google has now releases their own 64-bit Android L preview image for the x86 emulator, and hopefully they’ll release a 64-bit ARM image and NDK sometimes in the near future, as 64-bit mobile devices are expected for Q1 2015. That means developers can now test the 64-bit version of their apps build for x86 using Google emulator. Java only apps should most probably work without issues, but apps relying on native code (C/C++/assembler) will certainly require a little bit more work.  The latest Android NDK (r10b) support 64-bit code, and apps can be built with x86_64 build target, or using APP_ABI=all64 in 64-bit support increases addressable memory space, provides a larger number of registers, and new instruction sets. To install the image, simply go to SDK Manager […]

Linaro 14.09 Release with Kernel 3.17 and Android 4.4.4

Linaro 14.09 has just been released with Linux kernel 3.17-rc4 (baseline), Linux 3.10.54 & 3.14.19 (LSK), and Android 4.4.2 & 4.4.4. Linaro has kept working on their member boards such as IFC6410 (Qualcomm), D01 (Huawei/Hisilicon), Ardnale (Samsung), and Juno (ARM). They’ve also announced they’ll change the tools to build GCC by using cbuild2 instead of cbuild1 for next release, and they’ve enabled a build with gcov (for code coverage analysis) which may mean they’ll work on reducing the kernel size by getting rid off unused code. I’ve also noticed the Arndale and Arndale Octa Ubuntu images are now based on Linux LSK with Mali GPU support since last month. Here are the highlights of this release: Linux Linaro 3.17-rc4-2014.09 GATOR version 5.19 updated topic from Qualcomm LT (ifc6410 board support) and HiSilicon LT updated Versatile Express ARM64 support (FVP Base and Foundation models, Juno) from ARM LT. updated Versatile Express patches from ARM LT updated LLVM topic (follows the community […]

Linaro 13.08 Release With Linux Kernel 3.11 and Android 4.3

Linaro 13.08 has been released with Linux Kernel 3.11-rc6 (stating), Kernel 3.10.9 (LSK – beta), and Android 4.3. This month is the first release based on Android 4.3, which was only pushed to AOSP at the end of last month. I can also see work on new SoCs/hardware this month with Texas Instruments Keystone II ARM Cortex A15+DSP SoC and Fujitsu AA9 board (Which processor?, I could not find out). A lot of work also appears to have gone in OpenEmbedded, further optimizations have gone into NEON optimized AES encryption in OpenSSL, and more. It’s also the first time I can see a Ubuntu Raring engineering build image for HighBank (Calxeda Energycore). Here are the highlights of this release: Android Engineering Android stack was tuned to achieve 100% CTS pass result on Android 4.3 Analyzing the UEFI EDK II boot loader for Android completed, implementation of fastboot application and USB drivers in progress. Builds and Baselines Linaro Stable Kernel (beta) […]

Collabora and Fluendo Release GStreamer SDK for Android

Collabora and Fluendo have recently announced the availability of GStreamer’s Software Development Kit for Android, which allows developers to create multimedia playback applications for Android smartphones and tablets using Gstreamer and the Android NDK.. The GStreamer SDK for Android targets Android 2.3.1 Gingerbread or higher (API Level 9 or greater). However, due to some of the restrictions of previous versions of Android, some features such as hardware acceleration are only available on Android 4.1 Jelly Bean (API Level 16 up). Normally, you’d need the GStreamer SDK which can be installed on Linux (Ubuntu, Fedora and Debian), Windows (XP/Vista/7/8) and Mac OS X (10.6 to 10.8). But for developing Android applications using Gstreamer, you don’t. What you do need first is a typical Android development environment with the latest Android SDK, the latest Android NDK, and optionally, but recommended, the Eclipse IDE with Android ADT and NDK plugins. Once everything is setup correctly, and you have made sure you can build […]

Android NDK Revision 8 Adds MIPS Architecture Support

Google has just released Android Native Development Kit Revision 8, the Android SDK that allows developers to reuse C/C++ code. This version adds support for MIPS architecture and fixes a few bugs. Here’s the changelog of the new features and most important bug fixes: Added support for the MIPS ABI, which allows you to generate machine code that runs on compatible MIPS-based Android devices. Major features for MIPS include MIPS-specific toolchains, system headers, libraries and debugging support. For more details regarding MIPS support, see docs/CPU-MIPS.htmlin the NDK package. Fixed a typo in GAbi++ implementation. Fixed an issue in which fails to copy libsupc++.*. You can download Android NDK version 8 to develop native apps for MIPS or take advantage of the new bug fixes. Previously, MIPS provided the Android NDK on their own website, but this version might be phased out, as MIPS support is now part of  the official Android NDK. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in […]

MIPS Releases Android NDK 7m

MIPS has just announced the release of the Android Native Development Kit version 7. It has the same APIs as the Android NDK revision 7 released in November 2011 (for Android 4.0), but adds support for MIPS architecture and the MIPS ABI . The NDK is available for Windows, Linux and MacOS. The NDK allows developers to use C/C++ code either to reuse existing C/C++ code or to improve the performance over code developed with Java. Note that MIPS states that “using native code does not result in an automatic performance increase, but always increases application complexity. If you have not run into any limitations using the Android framework APIs, you probably do not need the NDK.” The NDK can be downloaded for: Windows Linux Mac You’ll also have to download the Android MIPS SDK, if you want to use the NDK. Strangely, the Mac SDK is not available for download yet, although the NDK is. Instruction to install the […]
