Google Android wins in mobile developer survey; looks bad for Flash, Windows

I've been reading a new survey of mobile developers from VisionMobile. Around 400 developers were surveyed, and the platforms covered were iPhone, Android, Symbian, BlackBerry, Java ME, Windows Phone, Flash, and the mobile Web.

The topic is significant. Companies everywhere are crying out for mobile apps, especially for Apple iPhone but increasingly for Google Android as well. The device+cloud computing model is today's big trend, and support for mobile devices in some form or other is becoming necessary for a wide range of applications and web sites.

The first notable fact is the extent to which iPhone and Android dominate. This chart on page 10 tells the story: there is little relationship between the device installed base and the number of available apps. Windows Phone, for example, has 75 million devices out there but only 13,500 apps; iPhone has 60 million devices and 225,000 apps.

 The reason is that Apple has created a viable ecosystem for development, as well as a superb mobile platform. Much as I dislike the locked-down nature of that platform, and its Apple tax, I acknowledge and admire what has been achieved.

Android has just 20 million devices but 72,000 apps. I'd guess that the quality of those apps is not as high on average, but it's still clear that iPhone now has competition.

If this paper is to be believed, Android will even pass iPhone. Android is identified as the most popular among developers, with around 60% using it versus 50% on iPhone. Why?

We believe that Android's lead in developer mindshare ahead of Apple's iOS is down to two factors: first the $99 fee developers have to pay in order to deploy their applications, an entry barrier which reduces the innovation from developing countries. Secondly, the very effective use of open source licensing as a marketing technique to attract developers to Google's Android.

Another factor is that Android apparently offers the best developer experience. In an appendix, the survey tests iOS, Android, Symbian and Java ME for coding, debugging, device emulation and support resources. Novices could create a simple app more quickly on Android. The coding effort was less; building 9 simple apps took nearly 3000 lines of code on Symbian, versus just under 1500 lines on iPhone and a little over 1000 lines on Android. Debugging is faster on Android. The survey comes up with the following claim:

Using the above data, we can say that when developing common applications, each hour of work for a given Android developer, irrespective of level of experience, equals 1 hour and 10 minutes for a Symbian developer, 1 hour and 20 minutes for a Java ME developer and approximately 1 hour and 30 minutes for an iPhone developer.

Contentious, no doubt, and a lot will depend on what sort of app is being developed. Still, a good result for Android.

Both iPhone and Android seem safe bets, but what about other platforms? Adobe Flash is an interesting one:

Our research further indicates that Flash developer mindshare seems to be in decline, despite Flash's installed handset base of more than 1.3B devices. Adobe's string of execution failures has meant that the installed base for Flash Lite is extremely fragmented, breaking the write-once-show-anywhere story for media brands who are Adobe's key customers. At the same time, Flash, the much-touted replacement for Flash Lite, was more than 18 months late, while Flash Lite shipments have stagnated, dropping from 43 percent to 15 percent of handsets sold from 1H09 to 2H09. This leaves Adobe with a rapidly shrinking window of opportunity, primarily on Android handsets, while having been banned from Apple's growing empire, and slowly seeing the adoption of HTML5, yet another replacement threat for Flash.

That's overly negative in my view. In favour of Flash is that it runs on the Web and desktop as well as on mobile, and will run across a number of mobile platforms. Even so, the research shows the pressure on Adobe to deliver mobile Flash, which will not be in the hands of the public until Android 1.2 "froyo" is availble on devices; and the Apple problem will not go away.

Symbian is in trouble too; in fact, since Nokia is now moving to MeeGo for smartphones, it now has little interest for developers. Some observers think Nokia should go to Android instead.

Java ME? Windows?

The vast majority of Java ME respondents have lost faith in the write-once-runanywhere vision. Moreover, anecdotal developer testimonials suggest that half of Windows Phone MVP developers (valued for their commitment to the platform) carry an iPhone, and would think twice before re-investing in Windows Phone.

That strikes me as accurate. Predicting the future is hard though. Google Android came from nowhere; it is possible that a couple of years from now different patterns will have emerged.

For now though, it's iPhone and Android all the way.
