Hi All,

Hopefully this will help demystify the build process

Notation:
 ()
  |
  + 
  |
  *

  \-> 
 ()

The file sizes are arbitrary and are based on the current configuration
options I have set for a small kernel. They are simply there to illustrate
the relative differences in file sizes.

Note that vmlinux.o is not used to generate bzImage but I've included it
for completeness

[Android] My Tip; Android Resolution Problem

Android Resolution Problem

Your App resolution wil be fixed 320x480(Portrait) if you missed the minSdkVersion.
so, you should be set it to 4(Android SDK Version 1.6) or higher.

Adds this into your AndroidManifest.xml:
Note: Change "(" to "<" and ")" to ">"
(manifest)
...
(uses-sdk android:minSdkVersion="4")(/uses-sdk)
(/manifest)

I've tested on Samsung Galaxy Tab.

[Android] Android Coverflow Widget

Android Coverflow Widget
http://www.inter-fuser.com/2010/01/android-coverflow-widget.html

Android Coverflow Widget V2
http://www.inter-fuser.com/2010/02/android-coverflow-widget-v2.html

Android Coverflow Widget V2
It's been a while now and I've been pretty busy with life, work, and other things, but at last here's a new version of the coverflow widget that I released a while back. There's not really much new functionality here, but I have cut down the amount of code needed by a lot. Gone are the CoverAbsSpinner and the CoverAdapterView classes and now we are left with just the CoverFlow class weighing in at less than 200 lines of code. Of course, you still have to instantiate it and populate it using an ImageAdapter so I'll also include the activity class for doing those tasks as well.

Background
The basic idea is that the Coverflow widget works very much like the standard Android Gallery widget, but with the addition of the rotation of the images. For more background information on the Coverflow widget see my original post here.

How to use
In your Android project create a package called com.example.coverflow, and in this place the CoverFlow class. Now all you need is an activity to instantiate the Coverflow widget in this example the activity class is called CoverflowExample. CoverFlowExample simply extends Activity and instantiates a Coverflow class in it's onCreate method. It also has an internal Class, ImageAdapter which we use as the adapter for the Coverflow widget, much as we would for a Gallery widget. It is also possible to use the Coverflow widget when it is specified in an XML layout file.

The CoverFlow and CoverflowExample classes are here:

Code explanation
The CoverflowExample Code contains some extra code for creating reflections of the images, but apart from this is a standard activity class of the kind used with the Gallery widget.

The CoverFlow class extends the Gallery widget , but now we override a few methods to allow us to transform the images before they are displayed. The most important method that we override is the getChildStaticTransformation method. Here I have to say thank you to a user called Nerdrow on the Android developers group who first showed me an example of overriding this method.  By setting setStaticTransformationsEnabled in the constructors, we are telling the parent ViewGroup of the Coverflow class to invoke getChildStaticTransformation every time one of our images in drawn. In getChildStaticTransformation we simply calculate and apply a rotation and scale to the ImageView depending on it's position relative to the centre of the Coverflow widget. We also override the onSizeChanged method. This method is called every time the widget changes size e.g. when we change the orientation of the phone from portrait to landscape. In the onSizeChanged method we just get the centre position of the coverflow widget. There are also a few parameters that we can set, mZoomMax controls the maximum zoom of the central image and mMaxRotationAngle sets the maximum rotation angle of each image.

Thanks
Lastly, I just wanted to say thanks to everyone who has commented and given me feedback on the coverflow widget. It's be really positive and great to hear that people have got it working successfully on a range of devices such as the HTC magic , Motorolla droid and Nexus 1. There's still more to do for the coverflow widget and I'll release new version as and when I make updates. If anyone has anymore suggests for cool widgets or enhancements to this Coverflow widget then please do get in touch.

Great work!

Win32-GuiTest - Perl GUI Test Utilities

Win32-GuiTest - Perl GUI Test Utilities
Source: http://search.cpan.org/~karasik/Win32-GuiTest-1.57/

SYNOPSIS
      use Win32::GuiTest qw(FindWindowLike GetWindowText
        SetForegroundWindow SendKeys);

      $Win32::GuiTest::debug = 0; # Set to "1" to enable verbose mode

      my @windows = FindWindowLike(0, "^Microsoft Excel", "^XLMAIN\$");
      for (@windows) {
          print "$_>\t'", GetWindowText($_), "'\n";
          SetForegroundWindow($_);
          SendKeys("%fn~a{TAB}b{TAB}{BS}{DOWN}");
      }

DESCRIPTION
    Most GUI test scripts I have seen/written for Win32 use some variant of
    Visual Basic (e.g. MS-VB or MS-Visual Test). The main reason is the
    availability of the SendKeys function.
...

-----
This is a great utilities. we can handling a win32 app GUI as a perl script.
This means you don't need to yourself test anymore for app test (i.e., in QA).
Just make a script then do the test. easy ?
