Installing Android 2.2 "Froyo" On the Nexus One 154

gjt writes "I awoke this morning to see TechCrunch's MG Siegler post what appeared to be the first news of Froyo's availability. I frantically went to my phone's settings and tried to check for an update -oe but no luck. Then I went to xda-developers.com and sure enough there was a very long thread (now over 132 pages) of fellow eager beavers waiting for release (and trying to figure out how to get it). Several hours went by waiting for a semi-technical user to get the update and check the Android logs for the download location. It turns out you can get it straight from Google. With the information scattered around in different places I decided to consolidate the How-To into a single post." Note: According to attached comments, and to the TechCrunch story, it seems this is a staggered rollout, so not every Android owner may be able to try it out yet.

Installing Android 2.2 "Froyo" On the Nexus One

  • If I'm not mistaken, Froyo introduces Flash on Android, so I guess we'll get to see whether the Flash-haters were right about how much Flash on mobile would suck.

      I think the better test will really be for when Froyo gets ported to the G1 and seeing how Flash performs then... I don't know that JIT will help much.

      • The JIT compiler shouldn't help at all. Given the performance needs of flash, it's almost certain that Adobe has it running natively. The only way in which the JIT will affect a native application is by clearing up resources being used by other applications.
        • JIT is going to more memory because you'll have both native and vm instructions in memory, whereas before you'd only have interpreted code. It's worth the tradeoff of course and will become more valuable as phone memory grows.

          Dalvik's JIT compilation is going to allow future Android applications to meet and exceed the performance of applications compiled ahead of time ("native" applications). Native is really a bad term because both dynamically JIT'd code and statically compiled code is native. The main dif

          • *going to use, dammit

          • Profiling does that exact same thing and is already in GCC and visual studio. Sure it's not as elegent as java and JIT but it's still there and doesn't hog memory.

            • GCC and Visual Studio are only used at compile time, not when deployed to end users during execution. They are limited in what they can optimize at this point in time.

              Example: Java and other optimizing JITs can devirtualize methods at runtime, effectively removing lots of lookups (possibly expensive branches) thus cache misses and other hazards resulting from heavy OO/polymorphism. GCC and Visual Studio cannot do this because they have no way of knowing what type a call site may be at an arbitrary execution

              • Mostly theoretical optimizations. You'll be hard pressed to find many real world cases where a JIT'd Java app will run faster than a native C/C++ app for a variety of reasons. Conversely, you will not be hard pressed to find C/C++ programs which perform better than a Java JIT'd app.

                Furthermore - if you care about performance (a lot of the time you frankly don't, at the level these optimizations would matter) you can just...not use a lot of virtualized methods and take other precautions to make sure you re

              • GCC and Visual Studio are only used at compile time, not when deployed to end users during execution.

                Not exactly. Profiling [wikipedia.org] which is what I was talking about is when the program is analysed at execution time.

                You compile your code, run it, profile it and then compile again with the profiler optimisations. Sure, it's not as elegant as java JIT done on the user machine however it also doesn't bog down a user's machine doing something the developer should have done on their own machines before release.

                • You clearly don't understand what we're talking about.

                  • Thanks for that. Your remarks/insults have completely convinced me that Java is superior and should be used for everything. Oh wait, no, no you have not.

          • Is there some reason why the system needs to keep the original blocks of vm code in memory once they've been compiled into native code?

            • by chromatic ( 9471 )

              If you use a tracing JIT strategy with guards (such that you can specialize a basic block based on the type of specific arguments), you need the option to fall back to the non-JIT version if the guard checks fail.

        • by mlts ( 1038732 ) *

          JIT compilers do help. A good example of this is .NET, where it uses an intermediary language which is compiled/translated for the CPU it is running on, and the native binaries are cached, and complaints about performance on .NET are fairly few from what I've read.

          Java has had a bad reputation in performance, but in reality, those days are in the past. There are other issues with Java, but those are not performance related unless it deals with direct hardware calls, and one can use native code for that.

        Have you heard definitively that Froyo will be ported to the G1? I was under the impression that Froyo and even Eclair are too big to fit on the G1. I'd love to be proven wrong -- I have two old G1s sitting in a drawer and would love to put Froyo on them. Froyo arrived on my N1 last night, and I'm very happy with it so far; there are lots of nice incremental improvements. But as far as I know, nobody is working on shrinking Froyo down enough to fit the G1.

        -- Laura

        Disclaimer: I'm an engineer at Google, but I have no inside knowledge of what the Android folks are doing. I didn't even know Froyo had been released until I saw the giant styrofoam frozen yogurt in front of building 44.

        • Eclair works on the G1 with Cyanogen's CM5 ROM, but it's pretty slow unless you have SD swap. Even then, you need a Class 6 SD for it to be effective.

        You can also just go to Adobe's website and click "get flash" the link will take you to the market to download it.

        One suggestion for those that install it, go into your settings and enable plugins 'on-demand' That way you will only get the Flash you want. It shows a little down arrow in place of the Flash that you click to enable. It's like a built in Flashblock/Adblock extension.

        Also IMO, considering the platform, I think the Flash is working rather well. I quite enjoyed watching some Zero Punctuation videos on Escapist.com already.

          I installed flash on my N1 and noticed a ton of flash ads, and thought maybe Jobs was right! I normally use an ad blocker when browsing (desktop) and had forgotten how bad it could be. That click to play thing will do the trick until I find a proper ad blocker.

      Flash Lite 4 is in the HTC Desire already. It works perfectly fine and provides a substantial amount of what the full Flash 10.1 would supply.

      Point being Flash doesn't suck and if it did, it would be beyond the realms of science to think of ways to implement it in a less CPU intensive fashion, e.g. browser doesn't launch flash apps until you click on them, or only launches same domain flash by default.

Once it 'fails' you have the option of rebooting, and no harm done. There was a 3rd party one released (linked through engadget) which may work for you if you've rooted your phone previously.

    Remember if your rooted and update to this, you'll probably have to re root it and install a new rom all over again to get all your rooted programs working. Unless you know how to use adb and the other utils to picjk apart features very well, You probably should just wait till your prefered flavor rom has the new features integrated. It shouldn't take long.

        For those too lazy to read your link, here is the relevant excerpt:

        As for the battery life, Greer said it's not as horrible as Steve Jobs might have made it out to be in his open letter earlier this month. "It's not too bad," he said. "Android has a little bit of an issue with battery life anyway. I just plug it in to my laptop, so I'm not super sensitive to it. I'd definitely say it depends on the game too."

        So he's saying it's "not too bad", but he keeps his phone plugged into a charger/laptop. Okay.

    Besides the fact that the link to the file in the summary didn't work, there are other potential problems if you click through to the source (on the forums, not the blog linked here).

    The procedure that's linked to will get you to 2.2, but it won't be rooted even if you were rooted before.

    I just did the classic "spend two hours trying to fix what you screwed up" routine trying to get it rooted again so that I could run the backup created by titanium backup, which requires root.

    For those interested, the steps for a fool-proof upgrade if you're rooted are:

    -Do a full backup using titanium backup first, obviously
