What is Android?
Developed by the Open Handset Alliance, Android brings Internet-style innovation and openness to mobile phones.
Android™ delivers a complete set of software for mobile devices: an operating system, middleware and key mobile applications. The Android Software Development Kit (SDK) is now available.
Open
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 was built to be truly open. For example, an application can 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 was designed to optimize memory and hardware resources in a mobile environment. Android is 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 are 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 can 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.

Blog Tips
Blog Project: 30 Traffic Generation Tips
First of all a big “thank you”� for every one who participated. As I said before the number of entries surprised me (and the quality as well, I will definitely apply some of those tips myself).
Now, without further delay, the 30 Traffic Generation Tips�:
1. Sridhar Katakam
Keep track of blogs and leave comments on them. A good way to keep the conversation going is to install a MyBlogLog widget and visit the blog of people visiting your site.
2. Ian Delaney
Nothing creates long-term traffic more than value. Consider writing posts with resources or explaining how things work. Useful things get linked to and they get onto del.icio.us, which is far better long-term than a digg front page.
3. Scott Townsend
Inform search engines and aggregators like Technorati (using the ping functionality) when your blog is updated, this should ensure maximum traffic coming from those sources. (check the List of Ping Services)
4. Kyle
Simplify. Pay attention to complex issues in your field of work. It may be a big long publication that is hard to wade through or a concept that is hard to grasp. Reference it and make a shorter “for dummies” version with your own lessons learned and relevant tips. When doing this, I have been surprised to find that the simplified post will appear before the more complex version in search results. Perhaps this is why it results in increased traffic; people looking for more help or clarification on the subject will land on your blog.
5. Grant Gerver
Try to be polemic. I write obsessively about all-things political from the left-wing perspective in the form of humorous, sarcastic one-liners.
6. Daniel
A simple tip that will probably boost your page views: install a translator plugin. I decided to use a paid plugin for this, but if I am not wrong there are some free ones as well. The translation is not very good, as you can imagine, but it helps to attract readers that are not fluent in English.
7. Rory
Submit articles to blog carnivals (http://blogcarnival.com) that are related to your niche. Your article almost always gets posted, and it must generate a handful of visitors, at least.
8. Ramen Junkie
Newsgroups. I always see a spike when I post a review to a newsgroup.
9. Eric Atkins
Create a new design for your website. Not only will it be more attractive to your regular readers, but you can submit it to some CSS gallery showcase sites that feature great designs. This will give you exposure on those sites while generating a lot of traffic and backlinks from those types of sites.
10. Megan Taylor
Participate in conversations on related blogs. Start conversations on your own blog. Don’t just post about a story and leave it at that, engage your audience, ask questions and call to action.
11. Guido
Comment on blogs, write useful content and make good friends on forums.
12. Brian Auer
You must be active to generate traffic. I post comments on other blogs that are related to mine, and I post my site link in my signature at the forums. Spread the word about your blog and it will certainly attract readers.
13. Shankar Ganesh
Just browse around MyBlogLog.com and you will surely get visitors to your blog. Also try to join as many communities as possible that are related to your topic.
14. Andrew Timberlake
A great tip for generating traffic is off-line by including your url in all your off-line liturature from business cards, letterheads, pamphlets, adverts through in-store signage if applicable. I even have our website on my vehicle.
15. Cory OBrien
Read lots of other blogs. Leave trackbacks. Make sure your blog is optimized for search engines. Leverage social bookmarking sites like digg (both for new ideas and for traffic).
16. Jester
Leave comments on other blogs. If you’re already reading them, it takes
just a couple of seconds to leave a message agreeing or disagreeing
with the author, you get to leave a link to your site, and you will almost
ALWAYS get traffic from your comments.
17. Goerge Manty
Post 3-5 times a day. Use ping services like pingomatic or set up wordpress to ping some of the ping services. Engage your readers. Put up polls, ask them questions, give them quizes, free tools, etc. Make them want to come back and tell their friends about you.
18. Engtech
Community. It’s one word but it is the most important one when it comes to blogging. The only “blog metric” that makes sense is the vibrant community of readers it has. Building a community around your blog will bring you increased traffic, but how do you start? The boilerplate response to building traffic is always “SEO, social networking sites, and commenting on blogs” but it can be simplified to “be part of a community”. The easiest way to seed your blog is with an already existing community. But the only way to do that is to be part of the community yourself.
19. Chris
Squidoo Lenses are a good way to generate traffic. By using a lense,
you can generate your own custom “community” of webpages, including some
of the more popular pages in your “neighborhood.” Including your own
webpage in such a list is a good way of generating traffic.
20. Splork
I’ve had good success writing articles and submitting them to EzineArticles. Articles that have been written from well-researched keyword phrases and accepted by EzineArticles tend to rank very high in Google for that search term. Placing anchor text in the footer of those articles so the reader can visit my relevant website has always increased my site traffic.
21. Jen Gordon
I came upon some unexpected traffic when my blog popped up on some css design portals like www.cssmania.com and www.webcreme.com. If you can put some time into the concept behind and design for your blog, I’d recommend submitting your site to a design portal not only for
additional traffic but to build an additional community around your site.
22. Kat
I’ve recently gotten involved with several “MySpace-like” community sites that focus on my target audience. I share my thoughts in their forums, post intros to my real blog on their system blog and I’ve even created a group for my specific niche. It’s been very, very successful for me.
23. Inspirationbit
Well, obviously everyone knows that social bookmarking sites like Digg, del.icio.us, etc. bring lots of traffic. But I’m now submitting some of my articles to blogg-buzz.com (a digg like site for bloggers), and I always get not a bad traffic from there.
24. Mark Alves
Participate in Yahoo Answers and LinkedIn Answers where you can demonstrate your expertise, get associated with relevant keywords and put your URL out there.
25. Tillerman
Be the first to write a post about the ‘Top Ten Blogs’ in your niche. The post will rank highly in any general search for blogs in your niche and other bloggers in your niche write about the post and link to it.
26. Nick
Participating in forums is a great way to get loyal readers. Either link baiting people in your signature or posting great advice and tips will give you high quality traffic, which will result in return visitors.
27. Brandon Wood
A simple trick I’ve used to increase traffic to my blog is participate in group writing projects. In fact, that’s what I’m doing right now.
28. Alan Thomas
Don’t forget your archives. I just posted a roundup of all interviews I did over the past seven months. One of them generated a new link and a big traffic spike from a group of users that look like they will be loyal readers now.
29. KWiz
Write something controversial. I don’t think it’s good to write something controversial just for the purpose of getting traffic necessarily (especially if it’s only for that purpose and you’re being disingenuous), but it works.
30. Dennis Coughlin
Find the best blogs on your niche and contact the authors. Introduce yourself and send a link of your blog. This might help them to discover your blog, read it and possibly link to it.

PHP If...Else Statements
Conditional statements are used to perform different actions based on different conditions.
Conditional Statements
Very often when you write code, you want to perform different actions for different decisions.
You can use conditional statements in your code to do this.
In PHP we have the following conditional statements:
* if statement - use this statement to execute some code only if a specified condition is true
* if...else statement - use this statement to execute some code if a condition is true and another code if the condition is false
* if...elseif....else statement - use this statement to select one of several blocks of code to be executed
* switch statement - use this statement to select one of many blocks of code to be executed
The if Statement
Use the if statement to execute some code only if a specified condition is true.
Syntax
if (condition) code to be executed if condition is true;
The following example will output "Have a nice weekend!" if the current day is Friday:
<html>
<body>
<?php
$d=date("D");
if ($d=="Fri") echo "Have a nice weekend!";
?>
</body>
</html>
Notice that there is no ..else.. in this syntax. You tell the browser to execute some code only if the specified condition is true.
The if...else Statement
Use the if....else statement to execute some code if a condition is true and another code if a condition is false.
Syntax
if (condition)
code to be executed if condition is true;
else
code to be executed if condition is false;
Example
The following example will output "Have a nice weekend!" if the current day is Friday, otherwise it will output "Have a nice day!":
<html>
<body>
<?php
$d=date("D");
if ($d=="Fri")
echo "Have a nice weekend!";
else
echo "Have a nice day!";
?>
</body>
</html>
If more than one line should be executed if a condition is true/false, the lines should be enclosed within curly braces:
<html>
<body>
<?php
$d=date("D");
if ($d=="Fri")
{
echo "Hello!<br />";
echo "Have a nice weekend!";
echo "See you on Monday!";
}
?>
</body>
</html>
The if...elseif....else Statement
Use the if....elseif...else statement to select one of several blocks of code to be executed.
Syntax
if (condition)
code to be executed if condition is true;
elseif (condition)
code to be executed if condition is true;
else
code to be executed if condition is false;
Example
The following example will output "Have a nice weekend!" if the current day is Friday, and "Have a nice Sunday!" if the current day is Sunday. Otherwise it will output "Have a nice day!":
<html>
<body>
<?php
$d=date("D");
if ($d=="Fri")
echo "Have a nice weekend!";
elseif ($d=="Sun")
echo "Have a nice Sunday!";
else
echo "Have a nice day!";
?>
