    Fragmentation is mostly FUD, there are only a few screen sizes and the OS changes are pretty minimal.

      From the Android developer blog [blogspot.com]

      Because it means everything, it actually means nothing, so the term is useless. Stories on “fragmentation” are dramatic and they drive traffic to pundits’ blogs, but they have little to do with reality. “Fragmentation” is a bogeyman, a red herring, a story you tell to frighten junior developers. Yawn.

        Just because you're paranoid doesn't mean they're not out to get you.

        I have an HTC Tattoo, the I can't use a bunch of apps I'd love to use on it, a couple others crash. Fragmentation has pretty made Symbian a platform only the nerdiest geeks code for, I'd love to see that not happen to Android too.

      You will have either fragmentation, or stagnation as the device gets older. Even something totally controlled like the iPhone. As time goes on, one of three things will happen:

      1) Apple will introduce new iPhones with features the old ones do not, and cannot, have such as higher rez screens, faster CPUs, etc. Software for these new phones will not run properly, if at all on the old ones. The phones will fragment along the lines of new and old.

      2) Apple will refuse to introduce any features that would break compatibility with older phones. They maintain total compatibility through keeping various things at one spec. This leads to stagnation of increasing proportions as time goes on, such that new iPhones are literally years behind competing products.

      3) Apple discontinues all support for older iPhones. They have the service providers remotely kill the hardware so you are required to purchase new hardware.

      There's just no way around it. If you want new devices to have new capabilities, well it will lead to fragmentation. There are plenty of things you can do to help, particularly in making sure newer devices can seamlessly run older software, but you can't have all sorts of new stuff and have everything work just like it did before.

        3b) apple makes sure to plan for a "incompatible" hardware upgrade when most of the early adopter contracts about to expire, and therefor they will be looking around for a replacement anyways.

        planned obsolescence is a "wonderful" thing.

        • For sure, but that doesn't prevent fragmentation. People will refuse to upgrade. Just how it goes. Won't be the majority I suspect, most people who get smart phones like new gadgets and get new ones often. However there will be a non-trivial amount that won't. So as I said: You get fragmentation or stagnation.

          • And that is where the non user replaceable battery comes in. You see after 2 years my Iphone 3g is running about 70% of it's battery life than when i first got it. In 6 months my phone will be almost 2.5 years old and I will be ready for the next phone anyways.

            The real question is will I find a decent android phone with a decent UI that can easily surf the web, and you know make calls, or will i have to upgrade to an Iphone HD that comes out in 6 weeks?

      Agreed on screen changes. But there's a major psychological issue with people shelling out hundreds of dollars for what they perceive as the "latest, greatest" phone, and then 6 months later being told they are stuck on version 1.6 when we've already gone through 2.0, 2.01, 2.1 and are about to see 2.2.

      If you think this isn't real, go see the thread on Engadget right now on this topic. People are angry about it. Frankly, I'd be pretty angry if my phone was still running 1.5 (apparently a third of Android phones out there are still stuck on this old-ass version as of a few weeks ago, and a third or so were still on 1.6, with another third on 2.1).

      Mind you, almost every phone has at least an *unofficial* community-produced ROM that will get them the 2.1 features and apps. Even the klunky G1 which was the first Android phone can get there - it's just not officially supported, presumably because Google, HTC and T-Mobile don't want to push down an update that replaces the SPL - I guess they think the support costs from doing that would be higher than the PR costs of not doing it.

      So yeah, the issue is a bit overdone - or rather, it's not so much fragmentation of hardware specs that's the issue - I think allowing some hardware diversity is a good thing, it encourages innovation. The real issue is lack of hardware support from manufacturers and telcos after the point of sale. Google has up-to-now done basically nothing to force guaranteed support periods and guaranteed maximum release delays on a newly released OS version. I saw nothing in the article to address this.

      *That* is the real issue that gets people riled up. *That* is what the users at Engadget are seething over. They want 2.1. They don't want to be told "we can't support 2.1 on your 8 month old handset, eat a dick" by HTC or Sprint or Verizon or whoever. Google is letting the carriers and hardware manufacturers release products, pimp them, then drop support 3 months later. They need to force some structure on customer support - I don't think every piece of hardware should be supported forever, but I think a year of official support for the latest version releases after the last date you sold the product is a minimum, and I think that a 2-3 month lag from Google's release of a new version to an officially supported ROM from the hardware vendor and carrier is a maximum. If a vendor falls outside of those parameters, every handset of their should be banned from the market, effective instantly.

      That's the stick they need to support their customers. If Google doesn't man up and do this, I'm afraid it will do a significant amount of harm to the rapidly developing Android market.

        Android Market makes sure your app is only visible to those devices where it will run correctly, by filtering your app from devices which don't have the features you listed.

        I've seen this a lot with friends who have different android phones. Friend A with HTC: "Hey try this really cool app". Friend B with Motorola: "What App? I can't find it anywhere in the market place." My understanding is that the app doesn't even show up if their phone is not compatible, it's invisible. I guess they don't want a bunch of apps that when you bring up the page says, "Sorry your phone is not compatible".

        I also know from the QA side of the house that you can have the same phone hardware with 2 different OSs depending on the carrier. Usually we don't have major problems, but there can be glitches and bugs that are introduced. And then there is the speed of the upgrades. With the iPhone we looked at one major update per year. When we started working with Android last year it was 1.5 (which had been our for a while on the G1) and 1.6. Then suddenly it was 2.0, then 2.1, now 2.2 all the last 9 months or so. Apple has generally release a new OS every year with a minor .1 release shortly there after. Same with blackberry.

          Would you rather Google had named their Android updates in smaller numbers?

          Or are you saying that Google should slow down the rate of improvements to the OS because you can't keep up?

          If it's the second, then I advise you to target a release which offers you the features you need and stick to it. Android's backward compatibility works amazingly well.

        • I run a 1.6 Android phone. I heard that Google Earth was out and searched it. No such app.

          Neat trick, keeping me from installing something that wouldn't work on my phone, but I'd prefer "This app is not compatible with your device" and removing the 'install' option perhaps.

          At any rate, a minor user interface change.

      • Thats why I'm going for a N900 rather than a Android or iPhone.

      I am personally very hesitant to look at any android device due to the fragmentation. Hell, you have 1.6 devices being released alongside 2.1 devices. If this isn't fragmentation then what is?

      As has been posted, read some comments from users about how pissed they are that their 1.6 device won't run certain apps or is lacking features that could be implemented by a 2.x release but their carrier won't deploy any updates.

      While the fragmentation can't be squarely put at Google's feet, there's a shared responsibility between the hardware manufacturers, the carriers and Google to ensure that this doesn't happen. Unfortunately this hasn't happened and Android is headed squarely toward a cluster fuck.

        The stories just say that fragmentation is killing Android, but they provide no evidence. They are making the claims, here. I have found no evidence that there's a fragmentation problem. There are apps that don't work for all devices, but iPhone OS has that issue, too, and it's only going to get worse.

          Agreed, however the killing of the platform has started in minor ways, unless there's collaboration between carrier/manufacturer/Google it will end up as a platform that users don't want a bar of.

          Let's face it, we're not talking about techies who can handle that some apps don't work, we're talking about users. They don't know the difference between a 1.6 & 2.1 device, they just see a phone with Android across the box. If it doesn't work they'll never buy another Android phone.

          Sometimes it is difficult to step back and ask "What would a user do in this situation?". It's something that the IT industry seems to forget, that the users are what matters for a consumer device.

        • Got to agree with you. The "fragmentation" issue is a non starter, and is a good way to spot a pundit or expert that has no experience with Android other than molesting a phone at a cell phone booth in the mall.

        • The main problem with all the fragmentation, as I see it, is the uncertainty. Waiting for an update when your carrier/manufacturer etc. is unwilling to give any information as to when, or whether at all, an update is coming, is pretty crappy.

The fragmentation issue is a non starter, except with people who have no clue that Android apps run in a virtual machine, and are nearly totally insulated from the underlying hardware. Most of the whining about screen sizes comes from developers who want to use photoshop slicedowns as GUIs instead of using Android's GUI.

          • Yes, but even applications running under virtual machines use APIs, and Google spits out a new API every 3 months. Phones in general will NOT be upgraded to support the new APIs (it's an exception when they are), and developers have to either resort to multiple code paths for backwards compatibility, or drop support for older phones (where "older", here, means older than a couple of months). That's the issue of fragmentation.

    This wasn't his point, but the author of the article described the android fragmentation perfectly. Quote:

    * Bugs - devices might simply have bugs, such as a buggy Bluetooth driver or an incorrectly implemented GPS API.
    * Missing components - devices might omit hardware (such as a camera) that apps expect, and attempt to "fake" or stub out the corresponding API.
    * Added or altered APIs - devices might add or alter APIs that aren't part of standard Android. Done correctly this is innovation; done poorly and it's "embrace and extend".

    Each of these is an example of something that can make an app not run properly on a device. They might run, but they won't run properly. These are the things that I spend my time preventing.

    The only thing I might add is that devices of different resolutions can be annoying, especially if your app has static images or custom widgets.

        The big issue is that the density increases but the screen size remains the same, so if your app isn't DPI aware things get small and hard to control. Desktop app developers tend to be fixed DPI - a larger window lets you show more information. Ditto web developers. But high-DPI displays means you don't want to show more information, but you should scale everything up. Even pictures if it makes the picture grow from literal thumbnail to larger blob.

            You managed to not actually read the article, or only read the parts that agreed with you. Read a paragraph or two beyond what you quote above and read how they have to hide the existence of fragmentation by hiding apps from people who can't run them.

      I don't think that an Android device with a modified API should be allowed to be called an Android device. That said, I've never heard of any apps for which this was a problem.

      The camera thing...well that's an issue with iPhone OS, too. But most importantly, you can restrict your device to certain features in the marketplace, so this shouldn't be an issue.

    "The thing is, nobody ever defined “fragmentation”"

    Let me try: You have several different versions of Android 'in the wild' on different phones, different carriers, etc. There are different stances on whether these version of Android can be updated (based on manufacturer) etc. yadda yadda

    Now, looking at that situation, I would say 'fragmentation' is more along the lines of 'Is it going to remain easy for to target Android phones in general considering how many versions currently exist [/not obsolete] concurrently?'

    So yes, it is mainly about compatibility. But it also means (much like any other platform) if the version leaping continues (and so many versions exist concurrently all the time) playing to the 'lowest common denominator' of supported features will be required

      Since the market will let you set which devices your phones works with you can very easily have two versions of each app to deal with the two screen sizes. This can also be used to restrict your app to phones running which ever android version you like.

        my understanding is that it filters by minimum (and max if one want to) android version, and what specific "intents" (firmware/hardware features) the app requires. All this is feed by the device to the marketplace and so incompatible apps can be hidden away.

      Aren't the newer versions of iPhoneOS not available for older ipods (and possibly iphones)? If that's true, I think the change in features between the versions is much less 'backward-compatible' than the change between Android 1.5 and Android 2.0, at least from an app's perspective.

      For instance I doubt we'd find an iPhone developer willing to write their app for the iPhone OS 2.0 so that it'd work on older devices (and miss out on the cool multitasking of OS 4), whereas I'm sure that unless an Android devel

    this should have been made perfectly clear from google's side from day one. Yet everyone kept talking about android marketplace as if it was a part of the android source until the first android based devices without marketplace showed up, and none could figure out why.

    i only ran into it after ranting about google's mismanagement of marketplace access on some forum, and got a link handed to me.

    another issue is that 1.6 required that a compatible device could function as a phone. So any device thats been in development since 1.6 was first released, wont have marketplace unless its a phone or stalls its release until they can get 2.1 or newer working and approved by google. And even then the max resolution of the screen is 800x600, and i think the screen size is in the 5-7" range.

    basically, google is lagging badly behind where third parties want to go with android. And its not helping that marketplace is only really usable in select nations so far (and when a sim is inserted into the device).

      I bought an Android phone because it was supposed to be "open". Then I found that it's locked down to the bootloader, that I can compile the code downloaded from source.android.com but then I have no way of running it on the phone, and that even if I found some warranty-voiding hack to do it, I would lose all google apps, the marketplace, and an assorted array of hardware functionality such as camera and FM radio. Sigh.

  • by pocopoco ( 624442 ) on Tuesday June 01, 2010 @08:22PM (#32426078)

    I've developed 7 Android apps and the huge diversity of Android versions and devices out there really is a nightmare. I have an enormous number of extra code paths due to it. All this extra complexity makes apps tougher to write, tougher to test, tougher to debug, tougher to enhance.

    Some examples of bizarre stuff I have to do:
    Android 1.5 has a Java NIO bug that forces me to copy data to a temporary array on its way to buffers to be rendered via OpenGL. This hurts performance on older phones that often need it the most. It also means I have to do more testing to make sure both code paths are well exercised. I bet many developers don't even realize the bug is there an just have broken OpenGL apps on Android 1.5. The bug fix would be trivial to port back to Android 1.5, which would make it drastically more likely to get on to these older phones, but there's no sign this will ever happen. Do I keep code paths like this? Or do I give up the 25% of the market that is Android 1.5? Neither is desirable.

    Another really frustrating one is how I have to detect specific devices and request certain size depth buffers just to get decent performance. Hardware graphics acceleration is only enabled on the Samsung Galaxy for depth buffer size 16, for example, not for no depth buffer. Depth buffer size 24 works best on the Droid, etc.. The Galaxy has had this bug for a very long time. The Archos tablet has no hardware acceleration and there are promises that cheaper phones will be similar. Do I write all the extra code for adjusting rendering for each of these? Or do again give up large swaths of the market?

    Anyway, I'm constantly dealing with issues like this. It is really disappointing that Android team, the carriers, and the device manufacturers don't do more to prevent it. Doing things like back porting fixes so that older phones can be more trivially updated would help enormous numbers of apps and app developers compared to the very few resources needed on Google's part to do it.

    Meanwhile Google isn't even interested in solutions to these problems from what I've seen. One developer brought up another potential solution during a session at Google IO. He suggested making the highest level of Android a distributable framework, like .NET. This would allow updating it much easier. Not nearly as many phones would be stranded with old, buggy versions of the Java portion of Android at least. The Google staffers just brushed the idea off without even discussing it. They said fragmentation should really be called progress and to deal with it.

    This isn't really surprising. If you look at a recent app produced by Google, the Twitter app, you'll see that it is unavailable to a huge percentage of the market because they don't support older versions of Android with it. Independent developers can't afford to ignore large sections of the marketplace like that. Google isn't in the app business, so the Googlers just go ahead and ignore the issue. You can see a graph of the versions of the devices on Android Market here:
    http://developer.android.com/intl/fr/resources/dashboard/platform-versions.html [android.com]

    And of course there are plenty of devices not on Google's market, many of which are even less likely to receive updates because they are updated by PC software rather than over the air.

    So Googlers aren't even eating their own dog food on this issue. They just make app developers put up with it on their own, never experience it themselves, and then ridicule the issue as a bogeyman. I think I was happier before I read the blog post. At least then I could imagine they were working hard on the issue and just doing terrible at it. Now I know they don't even consider it an issue.

      Most of the phones that run 1.5 right now are terribly underpowered -- OpenGL on a G1 is almost a sick joke.

      If you're targeting OpenGL, you probably should cut your losses and cut them.

      I thought Java was a distributable framework, like .NET. And I doubt every .NET runtime (including Mono etc) is completely bug-free either.

      And Google have already said they planned to spin off components of the OS, where possible, to make updating those components much easier.

      If they made an update, say 1.5.1, you would still want the old code path for the devices that hadn't upgraded - which leaves you in exactly the same position you are in now.

      I'm not sure what you want Google to do about this. Do you want Google to dictate a certain hardware spec to all the vendors? If you favor a consistent platform (more or less) from a well-known set of hardware on a single carrier, you should go with Apple.
