Mobile 2.0 Europe-Priya Prakash presents Nokia's vision on 'Beyond Free'

BARCELONA -Priya Prakash (formerly at Flirtomatic) presented Nokia's vision on what she see's as the customer's perception on what is (or should be) free on mobile. One of the insights included the fact that customers can perceive greater value from a mobile proposition purely by the fact they have to pay for it. More insights are in the presentation here.

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.

Mobile 2.0 Europe-roundup

BARCELONA -Mobile 2.0 Europe has come and gone again this year, attracting once again some of the finest mobile minds and entrepreneurs to Barcelona.

The (now 2-day) European showcase of mobile startups and trends in mobile this year gave everyone some extra food for thought with Tom Raftery on Mobile Sustainability and Regine Debatty on Mobile Culture.

Tom gave a thought-provoking presentation on why most telcos are not doing enough about achieving sustainability (with some squirming in the front seat from Carlos Domingo of Telefonica but pleased faces from Vodafone, with Tom's thumbs-up of their corporate web policy on green issues).

Regine offered a visually pleasing interlude of examples of not-for-profit mobile art and culture, with examples of giant SMS mobile screen projections (SMS Guerilla Projector) on the backs of innocent pedestrians (check out www.we-make-money-not-art.com) .

The panel on 'Beyond Free' managed to top last year's after lunch panel (on the role of Mobile Operators in fostering innovation) in terms of provocative debate, fuelled by some diverging points of view between Inma Martinez (Moderator) and Ian Ginn (seasoned web/mobile entrepreneur).

The conclusion from the panel, if there was one, is that mobile startups are still seen as an (un)necessary evil by most VC's but are treated as misunderstood children because they don't fit in the VC's risk/return equations.

You can find all the links to the presentations on the official event site here. A big round of applause to Rudy,Carles and the rest of the Mobile 2.0 Committee for organising (and pulling off) yet another great mobile event in Barcelona.

I will post some of my videos of the presentations by Ted Morgan of Skyhook Wireless and Priya Prakash of Nokia, starting with this one below:
