Cool apps that surprise and delight mobile users, built by developers like you, will be a huge part of the Android vision. To support you in your efforts, Google has launched the Android Developer Challenge, which will provide $10 million in awards -- no strings attached -- for great mobile apps built on the Android platform.

How It Works

The award money will be distributed equally between two Android Developer Challenges:
Android Developer Challenge I: We will accept submissions from January 2 through March 3, 2008
Android Developer Challenge II: This part will launch after the first handsets built on the platform become available in the second half of 2008
In the Android Developer Challenge I, the 50 most promising entries received by March 3 will each receive a $25,000 award to fund further development. Those selected will then be eligible for even greater recognition via ten $275,000 awards and ten $100,000 awards.

Build Your Favorite Mobile Application

We welcome all types of applications but are looking to reward innovative, useful apps that make use of Android's capabilities to deliver a better mobile experience. Here are some suggested areas of focus to get you started:

  • Social networking

  • Media consumption, management, editing, or sharing, e.g., photos

  • Productivity and collaboration such as email, IM, calendar, etc.

  • Gaming

  • News and information

  • Rethinking of traditional user interfaces

  • Use of mash-up functionality

  • Use of location-based services

  • Humanitarian benefits

  • Applications in service of global economic development

  • Whatever you're excited about!

So lets gear up and come up with ideas.

A Mashup has been created for Pune GTUG. The Mashup right has following features

1. Pulling the Pune GTUG Blog
2. Pulling threads from Pune GTUG Google Group
3. Map showing GTUGS all across the world
4. A Calendar Event Listing for Pune GTUG
5. A List of Ideas against a particular Google Technology

Note- I recommend using FireFox, the mashup does not seem to be working well with IE.

In future many more things would be added, and members of Pune GTUG Google Group will also be made members to this mashup.
Very soon, I also plan to release a Google Presentation about what is a Mashup and how to create the simplest of Mashups.

Google Ajax Search and Ajax Feeds

Existing Search Paradigm
The concept of Search page and a Feeds aggregrator is not old, most of us are much aware of it. However, the fact remains internet is a growing store of information, and as each day passes more and more information is added. Being good news, this is also a bad news, because reaching the right kind of information becomes difficult.

We all have been using Google's search engine for doing our searches and narrowing down to the information we need. Also some of us would already be we aware of Google's Feed Aggregator to aggregate the feeds we are interested in.

Existing Search capabilities already available
The following has been used by many users but is not so userful for people interested in the conference.

New Scenario - Getting your visitor to right content
Having said that, now think about a scenario, in which you wish to invite number fo people to Google's Technology Conference in lets say New Jersey. A number of people who have never been to New Jersey would come the very first time. I as a organizer would have enough knowledge about New Jersey, where the Venue, and what to expect near the venue. This is a place where Google Ajax Search and Feed APIs are the most appropriate to be used.

Example- Ajax Search Blogspot

Dynamic Content
The organizer can typically put a blog for the conference. But instead of keeping the blogs static in which user can only read information, Ajax Search and Feed APIs can be used to make it more powerful and intutive to the user.

For example, search bar can be put on the right side of the blog allowing user to search right there. A Video Search bar can be provided to allow user to search for vidoes. A Map Search with a map can be shown in the right side, with some keyword (links) put below, to show nearest accomodations, coffee shop. User can click on these to get more information. User can also do he own LOCAL search to find what he/she wishes to find near the conference.
A Video Bar could be provided in the same page on the left side to may be show what happened last year in the conference.

The whole idea is to get the user access the right kind of information, painlessly. Since the conference blog has an intend, the search options provided to the users too have the same intend is to help people interested in attending the conference.

Try it out
Visit to see the Ajax search in Action, see how easy you can reach the information which you intend to reach.

Technical Capabilities of Ajax Search
The following searches are possible
1. Local Search
2. Typical Web Search
3. Video Search
4. Blog Search
5. News Search
6. Image Search
7. Book Search

Industry Leaders Announce Open Platform for Mobile Devices

Android™ will deliver a complete set of software for mobile devices: an operating system, middleware and key mobile applications. On November 12, we will release an early look at the Android Software Development Kit (SDK) to allow developers to build rich mobile applications.
Android was built from the ground-up to enable developers to create compelling mobile applications that take full advantage of all a handset has to offer. It is built to be truly open. For example, an application could call upon any of the phone's core functionality such as making calls, sending text messages, or using the camera, allowing developers to create richer and more cohesive experiences for users. Android is built on the open Linux Kernel. Furthermore, it utilizes a custom virtual machine that has been designed to optimize memory and hardware resources in a mobile environment. Android will be open source; it can be liberally extended to incorporate new cutting edge technologies as they emerge. The platform will continue to evolve as the developer community works together to build innovative mobile applications.
All applications are created equal
Android does not differentiate between the phone's core applications and third-party applications. They can all be built to have equal access to a phone's capabilities providing users with a broad spectrum of applications and services. With devices built on the Android Platform, users will be able to fully tailor the phone to their interests. They can swap out the phone's homescreen, the style of the dialer, or any of the applications. They can even instruct their phones to use their favorite photo viewing application to handle the viewing of all photos.
Breaking down application boundaries
Android breaks down the barriers to building new and innovative applications. For example, a developer can combine information from the web with data on an individual's mobile phone -- such as the user's contacts, calendar, or geographic location -- to provide a more relevant user experience. With Android, a developer could build an application that enables users to view the location of their friends and be alerted when they are in the vicinity giving them a chance to connect.
Fast & easy application development
Android provides access to a wide range of useful libraries and tools that can be used to build rich applications. For example, Android enables developers to obtain the location of the device, and allows devices to communicate with one another enabling rich peer-to-peer social applications. In addition, Android includes a full set of tools that have been built from the ground up alongside the platform providing developers with high productivity and deep insight into their applications.

Google Gadgets and Mapplets Made Easy

We all have been using Google Gadgets on iGoogle and most of us love them (atleast I do alot). I was always curious on how to build my own one day and recently I tried doing so with success. Here is a video which will make it very easy for you to get started with Google Gadgets.

Enjoy the session!!

Once you know Google Gadgets moving towards Google Mapplets (Application which run in side Google Maps) is the next step. Google Mapplets open a lot of possibilities with Google Maps, instead of Google Maps being just a navigable map, it transforms it into powerful practical applications.

Imagine being able to search the real estate on various parameters right on the map, also get the directions to that place from your places. The possibilities are limitless.

Here is another Video session which will really make it very easy to catch on Google Mapplets. I suggest you try Google Gadgets (using above video) before actually trying your hands on this.

Go ahead and Enjoy!!

Grease the Gears by Krishna

Use Google Gears & Grease Monkey for a better web experience.

Here is an example.
Now, Google Reader works with Gears and is available offline... well,
not the entire application is offline... The Search feature is gone,
when you switch to offline-mode...
is a greasemonkey script that enables you to search your data in
offline mode. Of course this search may not be as intelligent as
Google Search, but it is something.

But, this is only the beginning. What synergy can be produced by
mixing Google Gears and GreaseMonkey? GreaseMonkey provides a hook to
write 'your' own javascript code on top of the application, and Google
Gears provides a Database to store 'your' data. A SDK in your browser
to customize any website!

You can keep track of information you want as a history in the cache
and retrieve them when you visit that site again. What you want to
store - is left to your necessity & imagination!!!

If you find any interesting use, do let me know.


Hi Everyone,
To explain the concept of GreaseMonkey working along side Google Gears, I have created a ScreenCase.
Krishna, Please review the video and let me know it it requires any change.

Thanks a lot Krishna for this information.
