Android Training & Tutorials

The Android team just announced the launch of Android Training a collection of classes aimed at helping developers to build better Android applications. Each class explains the steps required to solve a problem, or implement a feature, with code snippets and sample code. They’ll add more materials over time, but right now developers can already learn (more) about the following topics: Designing for Multiple Screens Improving Layout Performance Managing Audio Playback Optimizing Battery Life Remembering Users Sharing Content Capturing Photos Maintaining Multiple APKs Developing for Enterprise Monetizing Your App Designing Effective Navigation There are currently 34 lessons on all those topics, and most include code samples such as the News Reader (Designing for Multiple Screens). You can get started immediately by visiting Android Training page.

Qt Labs Releases Qt 4.8.0

Qt Labs has just announced the release of Qt 4.8.0 featuring Qt Platform Abstraction, threaded OpenGL support, multithreaded HTTP and optimized file system access. Here are some of the new key features in Qt 4.8.0: Qt Platform Abstraction (QPA) QPA restructures the GUI stack to enable easier porting of Qt to different windowing systems and devices. Previously called Lighthouse. Threaded OpenGL supportEnables developers to render OpenGL from more than one thread concurrently. See Threaded OpenGL in 4.8 for more details. Multithreaded HTTP HTTP requests are now handled in a separate thread by default. This should make application guis smoother, as networking will no longer use the main event loop. Optimized file system access The file system stack received some heavy lifting under the hood. The result is better I/O performance, achieved by reducing the number of system calls performed for I/O and by better use of cached data, when available. […]

Android 4.0 Hardware Graphics Acceleration Coming to More Platforms

The Linaro Android Platform Team has just posted a weekly update to their progress. They are going to release 11.12 very soon with hardware graphics acceleration to 2 of their members development boards: ST Ericsson Nova A9500 Snowball and Samsung Exynos 4212 Origen boards. So if you have any boards or products based on those processors you should be able to get an hardware optimized version very soon. Hardware acceleration is already available on all OMAP4 platform such as Pandaboard, since this was the default Android ICS target. They also introduced support for the ARM DS-5 debugger, an Eclipse plug-in to help developer create high performance performance and low power native software by integrating a graphical debugger for code generated for the Android Native Development Kit (NDK) and a basic version of the ARM Streamline performance analysis tool. Here’s a list of this week achievements: Key Points for wider discussion […]

Build the bootloaders (U-boot & X-Loader) for Pandaboard

I’ve tried to compile u-boot and x-loader for Pandaboard by following the instructions given at http://omappedia.org/wiki/Get_started_with_ubuntu_on_omap4#Bootloaders. I did this in Ubuntu 10.04 LTS with Linaro gcc compiler. Here are the instructions for the build: Create the folders:

mkdir bootloader
cd bootloader

1 2	mkdir bootloader cd bootloader

Get u-boot and checkout the omap4_dev branch:

git clone git://git.omapzoom.org/repo/u-boot.git
cd u-boot
git checkout L24.9

git clone git://git.omapzoom.org/repo/u-boot.git

cd u-boot

git checkout L24.9

You may use a different tag. Simply run “git tag -l | grep L24” to see the list of tags. (I used the latest at the time of this post). Build u-boot for OMAP4

make ARCH=arm distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-

make ARCH=arm distclean

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-

At this point, you should get U-boot (u-boot.bin). get x-loader and checkout the omap4_dev branch:

cd ..
git clone git://git.omapzoom.org/repo/x-loader.git
cd x-loader
git checkout L24.9

cd ..

git clone git://git.omapzoom.org/repo/x-loader.git

cd x-loader

git checkout L24.9

N.B: Both u-boot and x-loader folders must be at the same directory level. build x-loader for OMAP4:

make ARCH=arm distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- ift

make ARCH=arm distclean

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- ift

The x-loader (MLO) should now be ready. Finally, you simply need to copy MLO and u-boot.bin files to the SD card.
