Android's "Non-Fragmentation Agreement" 142

superglaze writes "The biggest doubt cast over Android (whose SDK was released yesterday) has been the fact that much of it is licensed under Apache. There have been worries that manufacturers might fork the code road in a non-interoperable kind of way. I.e., they would have no obligation to feed back code to the wider Open Handset Alliance, or even tell the other members what alterations have been made. However, it turns out that Google made all the members sign a 'non-fragmentation agreement' to make sure everything works with everything. In theory at least. 'All of the partners have signed a non-fragmentation agreement saying they won't modify [the code] in non-compatible ways ... That is not to say that a company that is not part of the OHA could not do so.' Google's spokesperson highlighted the historical dangers of working with Java, the programming language that lies at the heart of Android. 'One of the current problems with mobile Java development is that Java has fragmented ... Java virtual machines have fragmented, but all the members of the OHA have agreed to use one virtual machine that can run script in Java'"

    How is this google vs apache? I don't understand (its early and I'm feeling fuzzy headed so forgive me). Google is using an apache license to release this... other than that I don't see asf involvement in the project. Maybe I'm missing something here? This article talks about all the involved parties signing an additional agreement separate from the license agreeing not do what MS did to Java before being sued.

    So... how is this google vs apache?

      Symbian was developed on hardware, on the lowest hardware then available so that it would be sure to run on everything. This made the design obsolete at launch and now it is so archaic(?) that people really resent that original decesion.

      Perhaps Google wants to avoid this. Wants apps that push the hardware requirements so that the Android phones will HAVE to be powerhouses, and it doesn't get trapped in the symbian or even MS trap of having to work on the cheapest shit some company can throw together.

      Apparently (I only have this from hearsay) symbian phones often miss basic hardware capabilties that drive a pc programmer up the wall because he suddenly has to code for features that have been present in PC's from the dawn of computing.

      All google now has to do, is convince mobile phone makers that it is in their best interest to make their phones capable of actually running the software currently being developed.

      Don't forget mobile tech moves fast but is expensive. If the companies could get away with yesterdays tech they would. That ain't good for us consumers, we want them to be pushed so we finally get some fully capable smart phones and not the same crippled yunk they have pushing on us.

    • Run your emulator in another emulator, maybe two or three levels deep. Emulators, not virtualizers. That should make it run slowly enough for you.

      There is no "speed that real hardware runs at," since each phone running Android software will be different, just like every PC is different. Think of Android as a PC in your pocket that has mobile phone capabilities.

      I haven't looked at the SDK, but from what I have heard you can configure the emulator a bit to reflect the capabilities of different types of phones.

      This is just plain wrong. Once you start looking at graphics, audio, keyboard input, bluetooth, gps, network, photo or video capture or anything beyond very basic apps, you reach the murky world of JSRs, which are bits of java that may or may not be included in a particular j2me installation. If they are included, many of them have lots left up to the implementation to decide, for example MMAPI leaves it up to the implementation whether to support MIDI sound, whether to support playing audio directly from code rather than from a file, whether to support recording, what file formats to support etc. You can't even reliably play audio files across platforms, let alone do interesting things like get at the camera, get video frames etc.

      Nokia phones for example, most will let you grab a single frame from the camera, some won't, but you can't grab multiple video frames without a 1/4 second delay per frame, whereas motorola phones, many will not let you at the camera at all, but those that will, will let you record multiple frames properly, except for a few which will only let you take single frames.

        No it is not wrong. Not all phones has camera snapshotting or audio recording capability which is why you need API:s that leaves it up to the manufacturer what to support. The only other alternative is that each manufacturer writes their own API for whatever features their phones support. All manufacturers had such API:s but are now trying to phase them out because it is easier to stick to standards than to invent your own. Which is exactly what Google is doing, which is exactly why they will fail to att

Now you've got to have four different try/catch segments, and best case scenario, you're going to trip three of those every time you call the thing.

        There are about 4 J2ME vendors that cover 90% of the phone market. The main problem comes from developers who assume that every phone has the snazzy new API they want to use, then find that people with older phones want to use their app too.

        And its not like there's a huge field when it comes to cell phone manufacturers. There's not thousands of different manufacturers, so google starts out with a de facto quasi-monopoly.

        So even if a fork came along that was better, the companies can't use it.

          Nokia would be the main non-member Google has to worry about. They are already using Linux on their Internet tablet devices, and are already porting WebKit to GTK so they can use it in place of Opera (which they currently use on those devices), so forking their own version of this platform might be quite attractive to them. Any smaller companies probably have more to gain by using the platform as-is, so they benefit from the upgrades and applications developed by/for their bigger competitors.

    • Forking - and even just the threat of forking - can be powerful forces for coordination. Reducing the freedom to fork tends to centralize control and reduce the size of the community for a project, while also restricting potential innovation. From Stephen Weber's The Success of Open Source (pp. 169-170):

    I agree that the use of the Apache licence is the biggest problem with Android.

    If Android had just used the GPL (which prohibits forking), then this problem would have avoided. There are lots of examples to back this up. For example, if Emacs had used the GPL, instead of the Apache licence, the XEmacs fork would never have occurred. And if Gnome and KDE would both switch to using the GPL licence, then the projects would just magically merge into one, and we wouldn't have the duplication of effort and lack of standards that you currently see on the Linux desktop.
