Stop Dreaming Start Action Great
The Great Depression was a worldwide economic downturn starting in most places in 1929 and ending at different times in the 1930s or early 1940s for different countries.[2] It was the largest and most severe economic depression in the 20th century, and is used in the 21st century as an example of how far the world's economy can decline.[3] The Great Depression originated in the United States; historians most often use a starting date of when the stock market crashed of October 29, 1929, known as Black Tuesday.The depression had devastating effects in virtually every country, rich and poor. International trade plunged by half to two-thirds, as did personal income, tax revenue, prices and profits. Cities all around the world were hit hard, especially those dependent on heavy industry. Construction was virtually halted in many countries. Farming and rural areas suffered as crop prices fell by approximately 60 percent.[4][5][6] Facing plummeting demand with few alternate sources of jobs, areas dependent on primary sector industries such as farming, mining and logging suffered the most.[7] However, even shortly after the Wall Street Crash of 1929, optimism persisted; John D. Rockefeller said that "These are days when many are discouraged. In the 93 years of my life, depressions have come and gone. Prosperity has always returned and will again."[8]source : wikipedia

ADC 2 Updates
Since the announcement of Android Developer Challenge 2 in May, Android phones continue to be deployed in countries worldwide. Android phones are currently available in over 20 countries, with more on the way. As I've mentioned earlier, we'll be including real-world users of these phones to help review and score your submissions. It is important to remember that your apps will be reviewed by judges around the world on actual devices; thus, be sure to make it extremely easy for users/judges to access your apps with minimum setup.
Some of you have been asking for clarifications on what we mean by "open only to applications that have not been published". To be specific, applications that are available on Android Market before August 1, 2009 will not be eligible to participate in the contest. Users have already been providing comments for apps that are currently available on Android Market, so it wouldn't make sense for them to "judge" the same apps again in this contest. In addition, apps that include or that are based on open source projects are fully welcomed, as long as the application itself is not on Android Market until August 1, 2009.
If you want to find out more details about ADC 2, you can find everything at the ADC 2 page along with the Terms and Conditions. For the moment, the most important thing to know is that ADC 2 submissions will be due August 31. I can't wait to see what you all come up with this time.
Happy coding -- and good luck!

Introducing Android 1.5 NDK, Release 1
Many of you have been asking for the ability to call into native code from your Android applications. I'm glad to announce that developers can now download the Android Native Development Kit from the Android developer site.
As you know, Android applications run in the Dalvik virtual machine. The NDK allows developers to implement parts of these applications using native-code languages such as C and C++. This can provide benefits to certain kinds of applications.
The NDK provides:
- a set of tools and build files used to generate native code libraries from C and C++ sources
- a way to embed the corresponding native libraries into application packages files (.apks) that can be deployed on Android devices
- a set of native system headers and libraries that will be supported in all future releases of the Android platform, starting from Android 1.5 documentation, samples and tutorials
This release of the NDK supports the ARMv5TE machine instruction set and provides stable headers for:
- libc, the standard C library
- libm, the standard math library
- the JNI interface
- libz, the common ZLib compression library
- liblog, used to send logcat messages to the kernel
Keep in mind that using the NDK will not be relevant for all Android applications. As a developer, you will need to balance its benefits against its drawbacks, which are numerous! Your application will be more complicated, have reduced compatibility, have no access to framework APIs, and be harder to debug. That said, some applications that have self-contained, CPU-intensive operations that don't allocate much memory may still benefit from increased performance and the ability to reuse existing code. Some examples are signal processing, intensive physics simulations, and some kinds of data processing.
For any questions on the NDK, please join the Android NDK forum.
Have fun.

Activities and Tasks Design Guidelines
For our third post in the series of Android UI, we're releasing Activity and Task Design Guidelines. This section of our guidelines aims to help you understand basic concepts of activities and tasks, how they work, and how to enrich the user experience you are creating.
We've packed a lot into this section, which is targeted at designers and developers. You'll see examples that will illustrate how to use our core principles and mechanisms, such as multitasking, activity reuse, intents, and the back stack.
Additionally, we are providing some best practices around our UI patterns such as notifications. For example, we'll show you how to design a notification so that it will take the user to the screen they expect. This behavior needs to be thought out, and doesn't necessarily just happen by default.
With helpful pointers to the API's and this documentation, we look forward to building your understanding of what it means to design and develop an Android UI.
