We called Google Maps Navigation a killer feature for Android 2.0 when Google announced it's release last month. Currently, however, there are only a few Android 2.0 phones on the market, so it only makes sense for Google to release this app for older phones as well.

Just like the Android 2.0 version, Google Maps Navigation for Android 1.6 will include voice guidance, traffic data, satellite and Street View imagery. The app will also show geographical information courtesy of the Google Maps Layers feature the company introduced earlier this year.

But did the message get through to potential phone buyers? It appears that it did...at least according to mobile analytics firm Flurry. In their latest report, the company found that the Droid is now the fastest-selling Android phone to date, beating the sales of the myTouch 3G by more than four times.

Flurry's analytics service monitors over 10,000 mobile applications on both the iPhone and Android, or approximately two out of every three iPhone and Android handsets on the market. While obviously this isn't a look at the mobile ecosystem as a whole, it's a big enough slice to form some initial conclusions about the popularity of the latest mobile device to run Android, Google's mobile operating system.

By monitoring the new Android devices on Flurry's system, the company estimated the first-week sales for the Droid handsets as compared with both the myTouch 3G and Apple's iPhone 3GS. Although the iPhone still outsold the Droid within its first week, Flurry notes that the iPhone simultaneously launched in 8 countries worldwide while the Droid only launched in the U.S.

It's also important to note that the iPhone 3GS was just the latest model of the iPhone to arrive on the market, it is not the original device. Prior to the 3GS, the iPhone had two previous versions, the second which finally allowed for 3G cellular access and GPS capabilities. This update made the iPhone 3G a hugely popular upgrade and the company sold 1 million or so units on their opening weekend. Comparing the third generation iPhone to the first version of the Droid isn't a true "apples to apples" comparison, but on the other hand, the comparison of the T-Mobile myTouch 3G and the Droid is.

According to Flurry, Droid is dramatically outselling the myTouch 3G based on first week sales. That may say something about the quality of the Droid's hardware, the impact of a good marketing campaign or perhaps even people's frustrations with the iPhone's limitations. Or maybe a little of each. Then again, Verizon has nearly triple the number of subscribers as T-Mobile, so they already have a head start.

The Growing Power of Android

In the end, while we can't take any of these numbers to the bank, what we can learn is that the Android OS is making serious headway in the smartphone market. Although no one Android phone on its own may beat the iPhone, as more and more "worthy competitors" launch on numerous hardware platforms, the Android OS's install base may eventually catch up to that of the iPhone's. 

In any event, that's what Google believes. In a recent earnings call, Google CEO Eric Schmidt proclaimed that "Android adoption is about to explode," citing 12 Android phones on 32 carriers in 26 countries. Research firm Gartner predicts that the Android OS may end up ranking second worldwide by 2012. However, if more of the Android launches prove to be as successful as it appears the Droid's may be, Android may move up the charts even faster than predicted. Of course, who ends up on top all depends on Apple's next move. If the company decides to launch their phone on more carriers, all bets are off. If that's the case, Apple's market share could double, says Morgan Stanley's Kathryn Huberty. But that doesn't necessarily mean that Android would be left far behind. "Android is "backed by the power of Google's search engine," said Huberty. "Google's other up-and-coming consumer and enterprise products should make [Android] a dominant platform."

In the Beginning

When handheld computers went mainstream, developers had only one choice: Palm Pilot. Within five years, they had Symbian and Pocket PC (later Windows Mobile) to consider also. By 2009, there were no less than eight major operating systems for smartphones: two versions of Windows Mobile, two versions for Blackberry, iPhone, Android, Symbian, and webOS, not to mention traditional feature phones running various flavors of Java.

The Impact

Developers were forced to make the tough choice of which operating system to develop for. Making it harder, customers were scattered and were requesting versions of a variety of platforms, with no one platform controlling the market, unlike the desktop world. Until a few months ago, they had only one choice: develop for each platform independently, picking and choosing which to support, each with huge costs and unknown payback.

That, however, is changing. Developers now have three ways to develop cross-platform. And while these technologies are still in their early days, they will evolve rapidly.

HTML 5 and the Mobile Web

One option is to forgo installed applications altogether and develop mobile Web applications. HTML 5, with its access to local databases, makes this possible. There are two major obstacles to this strategy right now: first, ubiquity of HTML 5-enabled browsers and, second, a willingness among customers to accept it as a standard.

While the first will be solved with time and pressure from other OS platforms, the second is a bigger problem. The customer's willingness to accept Web-based applications is a psychological change that takes years to evolve. Device owners have been trained that cell phone connections are inherently unstable. In many places the connection disappears, and until that is resolved this mental adjustment cannot begin to take hold.

Flash

Adobe recently announced its push into the mobile space, with Flash-enabled browsers for most platforms and a Flash-to-iPhone-app compiler for Apple's smartphones and handhelds. This would allow developers to write all of their apps in Flash and then deploy on multiple mobile browsers and the iPhone via a compiled application.

This still suffers from many of the same disadvantages of HTML 5, because it requires a psychological change in customers to accept running apps in the browser. In addition, Apple's hard-nosed stance against Flash in the browser will impede this movement because it will require two completely separate creation processes.

Finally, for Flash to take hold, operating system manufacturers will have to start treating Web-enabled applications the same as non-Web-enabled ones. For example, launching Web apps from the home page must become standard.

JavaScript Native Apps

A new class of applications has arisen. These are native applications that are compiled for a specific platform but that use Web technologies for the user interface. This has the most potential. The most prominent one currently is PhoneGap. Other solutions include Appcelerator and Rhomobile, which uses the Ruby on Rails Web development language.

These technologies, all open sourced, enable developers to write back-end processes in the native code and all of the user interfaces in HTML, CSS and JavaScript. This application is then compiled into a native application. It can be uploaded to app stores, distributed via downloading and installed directly to the device.

The fundamental problem with mobile development isn't the back end, though. The backbone of all of these platforms is C or Java, which is generally portable if written with that intention. The problem is user interface development, which requires deep knowledge and understanding of each mobile device. Making the UI cross-platform solves the vast majority of problems associated with this kind of development. If you had to point to where the approach falls short, it would be that cross-platform applications don't feel "native," a shortcoming that would be solved by good design and better CSS work!

Conclusion

As the smartphone market evolves, we are unlikely to see a clear winner as we did in the PC business; and because of that, developers will be forced to write for multiple platforms. But for the first time in a decade, developers have options for multiple-device development. The cost and learning curve associated with writing native apps for every platform can finally be mitigated.

While all of these technologies are early to market, the writing is clearly on the wall. After more than a decade of discussion, the combination of Flash, HTML 5 and JavaScript will make "write once, use everywhere" a reality.

Among the devices making the heaviest use of the mobile web are the iPhone and its non-smartphone counterpart, the iPod Touch. The data traffic created by these two handhelds has increased 19 times from September 2008 to this past month and now accounts for 43% of all smartphone requests worldwide. In the U.S., that percentage is even slightly higher, with iPhone traffic accounting for nearly half (48%) of all smartphone requests.

Apple devices (iPhone and iPod Touch) also claim the top two spots on both the U.S. and the worldwide charts of top handsets. However, feature phones like the RAZR v3 and Samsung's R450 are still making the top ten list as well and account for 60% of ad requests in the U.S. - a figure that's likely due to the unlimited data plans available with each of these devices.

Key Takeaway #2: Watch Out! Android is Rising Fast

Now climbing up the charts, Google's Android, the newcomer to the mobile operating system game, is beginning to have an impact on mobile web traffic as well. From August to September of 2009, the percentage of smartphone traffic generated by devices running the Android OS grew a whopping 13% over the course of the month. That's a dramatic increase in such a short period of time and gives credence to recent reports that Android is poised to become the number two smartphone in the worldwide market. While still far behind the iPhone OS in terms of traffic with only 17% of U.S. traffic and only 10% of traffic worldwide, Google's mobile OS is already beating out competitors like RIM, the maker of Blackberry devices, and Windows Mobile. It has also claimed two spots on the top 10 chart of handset models in the U.S with the HTC Dream coming in at number 3 and the HTC Magic coming in at number 10. Worldwide, the Dream is also number 3, but the Magic only makes it to spot number 15.

Key Takeaway #3: Outside of U.S., Mobile Web Strong in India, Indonesia, U.K., Philippines

When looking at the number of ad requests by country, the U.S. is still dominating with 47.3% of all requests coming from the States. The next nearest country, India, only comes in at 6.5%. Rounding out the top five are Indonesia, the U.K., and the Philippines. These numbers point to heavy mobile web use in each of these countries as compared with the rest of the world.

When grouped by larger regions, North America is number one with 49.5% of requests, most of that from the U.S., and the second largest region is Asia, accounting for 25.3% of requests. Western Europe, Africa, and Latin America follow with 9.4%, 5.3% and 5.0% respectively.

Looking at just percentage increases in traffic growth, a different picture appears. Latin America is showing a large percent increase year-over-year at 0.6%, second only to North America's 1.1%. Other regions in the top five, while still accounting for large numbers of requests, actually saw slight decreases in growth (less than 0.5%) over the past year.

Smartphones are Taking Over, Mobile Web Grows

While none of the data included in this report is all that surprising, it's interesting to see actual numbers put to the reported trends. We can now see the disproportionate amount of web surfing done by iPhone users, no doubt thanks to the phone's Safari web browser, a vast improvement over the browsers included in many other mobile devices on the market.

It's also worth noting how fast Android is moving up the charts right now. It could very well be the next contender to the smartphone crown, especially given the company's plans to continue spreading its OS across numerous devices worldwide. As Google CEO Eric Schmidt recently declared, "Android adoption is about to explode." Also, AdMob noted on an earlier blog entry that there are already 12 Android phones available through 32 carriers in 26 countries. By the time they release their next Mobile Metrics report, those numbers are sure to have increased.

What all this means to the consumer is that smartphones are now edging out feature phones as the devices of choice. More phones than ever come with the advanced capabilities like touchscreens, full-featured web browsers, and Wi-Fi. With features like these, more people will begin to surf the mobile web and download mobile applications. This, in turn, will drive related changes in mobile platforms, communication, e-Commerce, and more, all of which are bound to see similar upward trends over the coming months.

Lots of New Features

For now, only developers will have access to Android 2.0. Regular users won't be able to get their hands on this update until later this year.

The update features some impressive new functions, including support for synchronizing and managing multiple email accounts, an improved keyboard with a smarter dictionary and a browser that will be more like Safari on the iPhone, with support for double-tap zoom and HTML5.

Here are some of the new features that users can expect to see in Android 2.0:

Contacts and accounts

• Multiple accounts can be added to a device for email and contact synchronization, including Exchange accounts. (Handset manufacturers can choose whether to include Exchange support in their devices.)
• Developers can create sync adapters that provide synchronization with additional data sources.
• Quick Contact for Android provides instant access to a contact's information and communication modes. For example, a user can tap a contact photo and select to call, SMS, or email the person. Other applications such as Email, Messaging, and Calendar can also reveal the Quick Contact widget when you touch a contact photo or status icon.

Email

• Exchange support.
• Combined inbox to browse email from multiple accounts in one page.

Messaging

• Search functionality for all saved SMS and MMS messages.
• Auto delete the oldest messages in a conversation when a defined limit is reached.

Camera

• Built-in flash support
• Digital zoom
• Scene mode
• White balance
• Color effect
• Macro focus

Android virtual keyboard

• An improved keyboard layout makes it easier to hit the correct characters and improve typing speed.
• The framework's multi-touch support ensures that key presses aren't missed while typing rapidly with two fingers.
• A smarter dictionary learns from word usage and automatically includes contact names as suggestions.

Browser

• Refreshed UI with actionable browser URL bar enables users to directly tap the address bar for instant searches and navigation.
• Bookmarks with web page thumbnails.
• Support for double-tap zoom.
• Support for HTML5.

Calendar

• Agenda view provides infinite scrolling.
• Events indicate the attending status for each invitee.
• Invite new guests to events.

Mix-ins Add Social Networking Sites and More to Your Contacts

The AddressBook application isn't just one app - it's a combination of the core application and additional, optional apps called "mix-ins." Depending on your own personal preferences, you can download and install any of these mix-ins to integrate the social networking services of your choosing with the main AddressBook. After adding a mix-in, the app also helpfully auto-matches your phone's contacts to your friends on the social networking site you selected. The option to manually match your friends is available as well.

For the most part, this feature worked as advertised, but with Twitter there were some issues. The mix-in didn't pull in my complete friends list and when viewing the mix-in itself, contacts were listed as "null" instead of by their Twitter username. It's hard to say if this was an issue with the AddressBook itself or something that was going on with Twitter at the time, but it could point to a few kinks that need to be worked out.

Each social network has its own mix-in, but you can also find other mix-ins for social games like "AngelChess" for example. And because anyone can develop these mix-ins, the company hopes that developers will create even more to choose from in the future.

In addition, updates from your social networks will appear along with your other standard notifications in Android like new voicemails, new emails, new text messages, etc. You can finely control which networks and friend groups you receive notifications for, too, so you don't get overloaded with updates.

Similarities to Other Social Contacts Apps

At first the AddressBook application may bring to mind another mobile contacts app for iPhone - the newly launched Gist. However, although Gist's app also lets you keep tabs on what your contacts are up to through social networking integrations, Asurion's app is more of a consumer offering. There's currently no focus on integrating with CRM systems like Salesforce or even the business-focused social network LinkedIn.com.

Another great feature in the AddressBook app is "Smart Contacts." These are location-based business listings which provide quick access to maps, addresses, store hours, phone numbers and more. With these unique contacts added to your address book, you're able to find that company's nearest location with just a few taps. This feature somewhat resembles the "RingPages" feature in the upcoming iPhone app CallSpark. Those, too, are location-aware business listings which can be added to the main contact application.

Business Plan: App to be Free, Affiliate Model in the Future

For now, the company isn't as focused on their business model as they are on just increasing the adoption and the app's user base. However, they do say that the AddressBook app will remain a free download and will never include in-app ads. Instead, the company may eventually be able to generate revenue by sending traffic to the businesses included in the Smart Contacts section. Though the details of this affiliate model still need to be sketched out, it's clear that the company's goals don't involve having app owners pay for its services.

Update: The company now reports that the Twitter bug described above has been fixed.

On his blog, Freitas writes, "We have successfully ported the native C Tor app to Android and built an Android application bundle that installs, runs and provides the glue needed to make it useful to end users.... secure, anonymous access to the web via Tor on Android is now a reality."

However, the developers who are currently preparing anonymous mobile browsing for its premiere are seeking volunteers for the app and for preparing the privacy-focused Android browser, Shadow. Interested parties should contact Freitas.

In response to the mobile devs, HTC has previously stated it was waiting for its own developers to provide the source before releasing it publicly. As late as last week, HTC representatives had emailed developers saying, "At the moment we do not know when the kernel source for the Hero will be released," and "We are still pushing our developers to provide us with the source code and for the links to be added." Since the Android kernel is licensed under the GPL, this delay was creating both dissatisfaction and controversy in the community.

Or something along those lines. GPL non-compliance and hints of internal process and delivery issues don't mode well for the mobile manufacturer. After unfavorable coverage of the company's "foot-dragging" on Slashdot and long threads of modev complaints, we do hope that HTC's future Android projects will be more swiftly opened.

The Hero, as a device, is significant in itself, hence the enhanced perception of cruelty in HTC's not releasing its source code sooner. It's created huge waves in geek circles, beating out the iPhone for Gadget of the Year at the prestigious T3 awards and generating enough gadget-geek slavering to power a small city.

So, will the gadget geeks and modevs have to push for open sourcing every time a cool, Android-powered device is released? Where was the major malfunction that led to these delays? Were the HTC engineers thrown under the bus to allow leadership to save face, or do the HTC powers that be simply need to get their engineering team under control? Let us know your thoughts in the comments.

In January, 20 million people were accessing Facebook on their mobile phones. By September, that number had more than tripled to a whopping 65 million mobile users. As the company continues to upgrade the mobile user experience, the rate of content generation appears poised for unlimited growth. To test the redesigned mobile site visit touch.facebook.com.

In the mobile market, Fennec goes up against Opera Mobile and Skyfire, which are available on a wide variety of platforms. The most important competitor, however, is probably Safari, though Apple only makes its browser available on its own phones. Safari may not be available on a large number of different phones, but it has set the bar pretty high when it comes to the user experience that users now expect from a mobile browser. With the Awesome bar and Weave bookmark synchronization, Firefox, however, will offer a number of features that Safari doesn't currently offer. Fennec will also offer support for plugins.

Om Malik looked at an early version of Fennec on the Nokia N900 and thinks that the browser "is perhaps its single biggest standout feature" on the device.

Mozilla on the iPhone

Earlier last week, a number of rumors about a Mozilla app for the iPhone also started to make the rounds, though it remains unclear what this app would look like. Apple, after all, isn't likely to allow a full Firefox-based browser on the iPhone.

The dual-screen concept is definitely interesting and somewhat reminiscent of the rumored Barnes & Noble-branded eReader that is scheduled to be announced tomorrow. For now, Spring Design's press release remains quiet about any content partnerships. Even though the company says that the device will be able to connect to 3G, EVDO/CDMA and GSM networks, Spring Design doesn't appear to be ready to announce any partnerships there either.

Multimedia Books

Maybe the most interesting aspect of the device is that the company plans to give developers and publishers the ability to enhance the text that appears in the eInk screen with multimedia content on the LCD screen. This could open up a lot of new avenues for publishers, but at the same time, we have to wonder how many publishers would be willing to develop new content for this device. Creating an eBook version of a manuscript is easy, but adding additional content to this text could quickly become a costly undertaking.

Color Us Skeptical

Given how vague the details are, we remain skeptical about this device until we get more details. For now, all we know is that it will run Android, feature two screens and have an SD card slot, and that users will be able to cache Web content on the device and then display it on the eInk screen.

We also can't help but look at the device and think that it would be rather unwieldy to use. It is definitely exciting to see that somebody is using Android to develop an eReader, but this device seems to forgo usability for novelty. While we are all looking forward to color eInk displays, this device looks like an odd chimera that is meant to bridge the gap between these two generations. In the long run, this concept probably doesn't have much of a future.

Last month, Sprint also announced that it will offer Android devices in the near future, leaving AT&T as the only major wireless company in the US that doesn't offer an Android handset - though AT&T, of course, still holds the exclusive rights to the iPhone.

Taking on Apple

There can be no doubt that this partnership is aimed directly at Apple. Just a few days ago, Verizon launched a new advertising campaign that highlights the company's 3G network and spoofs Apple's "there's an app for that" campaign. While Verizon was always known for the quality of its network, though, it was never known for offering cutting-edge handsets - something that could now change.

During a teleconference after the announcement, both Verizon and Google stressed the fact that they want the phones to remain open. Apple, of course, makes no such promises and has regularly landed in hot water when it didn't allow certain apps like the Google Voice app into its store.

Big News for Android Developers

Android developers will surely be happy about this announcement. Verizon, after all, will bring millions of new customers to the Android platform and given that the company has no plans to make any changes to the Android Market, this will open up a large new market for Android apps. In this morning's teleconference, Verizon also noted that it will pre-load devices with applications from Google as well as third-party developers.

According to Best Buy chief marketing officer Barry Judge, the new applications, which also include several Facebook apps that will appear on the company's branded page, take advantage of the company's "Remix API," (application programming interface). This allows third-party developers to access Best Buy's inventory data, pricing, and product images for use in their web or mobile applications.

Next month, the first of several Google-created Best Buy applications will launch. The new app will allow consumers to do product searches and then will provide them with the location and directions to their nearest Best Buy store. It will even direct the user to the exact location of the product within the store itself. Phones sold in Best Buy will include the app pre-loaded onto the handsets prior to purchase. Also coming are applications designed specifically for Android, Google's mobile operating system, but there's no word yet as to what those apps will be. Best Buy currently carries two models of Android phones, the G1 and the myTouch 3G.

Other Plans: Websites, Gadget Deals, and Facebook Apps

In addition, the company is launching a dedicated website for Best Buy Mobile in October, is lining up exclusive deals to sell highly anticipated gadgets like Nokia's first netbook, the Booklet 3G, and is launching a series of Facebook applications.

The revamped Facebook page, which the company said will attract anywhere from 3 to 4 million fans, will offer several apps designed to help holiday shoppers find gifts. One, the "Hint Hacker," allows visitors to send gift hints to their family and friends about what products they're interested in. Another, called the "Holiday Morning Simulator," is a goofy Christmas card where Best Buy Blue Shirt employees sing holiday tunes, also addresses gift-purchasing questions. A third is a Facebook Secret Santa app. These, too, will be revealed in the coming weeks.

What's most interesting about Waze is how it uses the power of the crowd to build its map database. Just by driving along with the application open, users are contributing data to Waze. Although this does make the service somewhat dependent on building critical mass in order to be successful, the company is confident they can do so. That's because Waze originally launched in Israel and in less than a year's time, they already have 91% of the country mapped. Here in the U.S., that process will obviously take longer, but Waze believes they'll have at least one metropolitan area completed in the next three months - the San Francisco Bay area, of course.

Since the application is designed to provide traffic alerts, one of its features allows users to contribute additional information like whether that's a speed trap ahead or just a fender bender slowing things down. Users can upload photos, too, so other Waze drivers can actually see what's causing the problem. This feature is a little disconcerting, though, since it does require the driver to interact with the phone while behind the wheel. However, Waze encourages the use of these features only when stopped, or even better, by having a passenger enter this info instead. (At least they disabled typing while the car is in motion. Whew!)

Also new to Waze is turn-by-turn directions, now available for free within the application. That feature alone should encourage more users to give it a shot, especially those who haven't purchased their own standalone GPS-based navigation device yet.

Early adopters can download the free mobile application from the company's homepage here. Just remember: this service only arrived in the U.S. this May so at this point, it may be more about helping build the map data than it is about using what's already there.

For services that already offer support for geotagged information, including FriendFeed, for example, Pixelpipe will just use those services' native APIs to pass the information along. Pixelpipe already offered this feature when users uploaded geotagged media files, but now, the service will also enable this function for text-based status updates.

We know that Twitter will soon enable its geolocation API, which will hopefully enable a whole range of new services, so for Twitter users, this is really just a stop-gap measure and there are already a few other services out there that offer similar features for Twitter. For now, however, if you want to send text-based status updates to multiple services, this is the most convenient way to include geolocation information with your status updates.
