Debug android project with eclipse

By Pierre Lacave on Wednesday, December 16 2009, 14:44

Developing android application is fairly easy if you know java, but as it use a android virtual machine to run your application, debugs are somehow not clearly appearing.

The good news is Android Plugin for Eclipse also has excellent integration with the Eclipse debugger.

you can test by yourself by adding a NullPointerException into your code. If you run your application again, you'll eventually see this:

To find out more about the error, set a breakpoint in your source code on the line Object o = null; (double-click on the marker bar next to the source code line).

Then select Run > Debug History > Hello, Android from the menu to enter debug mode.

Your app will restart in the emulator, but this time it will suspend when it reaches the breakpoint you set.

You can then step through the code in Eclipse's Debug Perspective, just as you would for any other application.

Linux Kernel Update 2.6.31

By Pierre Lacave on Saturday, September 12 2009, 11:37

Linux 2.6.31 kernel released on 9 September, 2009

Among all the changes, a few changes deserve to be noticed here :

USB 3 support

Thanks to Intel, Linux now support USB 3 and xHCI.
No xHCI hardware hit the mass market yet.
Linux is still a step ahead !

CUSE

The awaited extension of the famous FUSE.
With this new "virtual device" File system,
we will be able to link application in different layers,
a good example case i read on the net would be
to "proxying" OSS audio from OSS apps through the ALSA userspace layer.

ATI kernel mode

For those having problem with your old ATI GPU,
this new release should fix quite a lot of freeze in X.

Better memomy management under pressure.

Benchmark showed a drop of 50% of memory major Fault
when using a graphical desktop !
