Everything you need to know about Android 2.2 (FroYo)

UPDATE (5/22/2010, 5:27 PM EDT): Android 2.2 is officially announced! Read all about its features in our new tell-all.

If there’s one thing smartphone enthusiasts really love, it’s a firmware update, and the Android ecosystem is about to get a big one: Android 2.2. Primed to launch later this month, Google has remained pretty mum about what to expect, but that hasn’t stopped the good word from making its rounds.

Codenamed FroYo (as in “Frozen Yogurt”), Android 2.2 follows Eclair (2.0/2.1), Donut (1.6) and Cupcake (1.5) as the fourth and newest dessert-themed edition of Android. Android 2.2’s official unveiling is expected at the Google I/O conference, which runs May 19-20.

The need for speed

If the performance of past Android releases was faster than a speeding bullet, then Android 2.2 is a hypersonic fighter jet bolted to a sixer of cruise missiles. Exclusive testing by the Android Police site has revealed that Android 2.2 is up to 450 per cent faster than Android 2.1 on the HTC Nexus One.

How Google did it: Android 2.2 comes packaged with a little piece of code called the just in time (JIT) compiler. A JIT compiler will increase the speed of Android and its applications by translating their code into a form that’s much faster for your phone to run.

It’s also believed that Google has performed some good ol’ fashion code improvement that would make Android quicker even without the JIT compiler.

Finally, it has been confirmed that Google has updated Android’s kernel (what is a kernel?) to a newer version that consumes less RAM. More RAM for users means better application performance.

Adobe Flash

While Apple has openly shunned Adobe’s Flash technology, Google has embraced it with open arms. It is confirmed that Android 2.2 will hit the streets with Adobe Flash 10.1, which will allow users to experience content like Farmville, PopCap games or Kongregate on the go.

How Google did it: Google and Adobe have been working overtime to make sure that the mobile version of Flash 10.1 is ready for the limelight. Early previews of the technology on the HTC Nexus One, such as the video below, give a tantalizing glimpse of things to come.

WiFi tethering

Another report from the Android Police site confirms that Android 2.2 will allow phones to serve as a WiFi hotspot for other wireless devices. Using a phone’s unlimited data plan, the WiFi hotspot feature could provide the Internet for you and your friends anywhere a 3G connection is available.

The catch: Mobile carriers hate tethering, because a tethered laptop will use more data than a phone ever would. Don’t expect the WiFi tethering feature to be free.

USB tethering

Android Police yet again delivers with news that Android 2.2 will also offer USB tethering. Faster than WiFi, USB tethering turns your phone into a surprisingly snappy modem that can make quick work of basic web browsing.

The catch: Carriers still hate tethering.

Better app storage

Android 2.2 will likely allow users to finally store applications on a microSD card. This has been a popular feature request amongst Android users, particularly those with phones offering limited onboard storage.

Why it matters: The best and brightest Android phones offer about 512 megabytes of onboard storage, but recent versions of Android use more than 60 per cent of that space, leaving limited room for a user’s applications. As Android apps continue to grow in size and number, moving them to the SD card may soon become a necessity.

Unconfirmed rumors

Gaming on the go has been a big push for Android. It has been said that Android 2.2 will feature enhancements to OpenGL ES 2.0, which will pave the way for faster, better-looking 3D graphics.

Next up, it has been widely speculated that Android 2.2 will finally activate the FM radio chips that lie silent in many of today’s popular Android phones. The same bundle of “experience” improvements, it is said, will also improve the accuracy of your phone’s touchscreen.

Cautious optimism

If you don’t own an HTC EVO 4G, Droid Incredible, Desire, Nexus One, Legend or Motorola Droid, it’s pretty unlikely that your carrier will ever work to bring Android 2.2 to your handset. Carriers like Verizon are already showing that older devices are on their last legs by retiring the Droid Eris this month.

Even if you are rocking one of Android’s newest phones, some patience will be needed. It takes time to design and test an OS upgrade that millions of users will depend on each and every day.

    Zanthian Nice article. I am still carrying an HTC dream around. So hopefully cyanogen is able to get 2.2 running on it. Already running 2.1.
  2. Thrax
    Thrax I don't doubt that XDA-Devs will be working overtime to jam 2.2 onto older handsets, especially with an official implementation of Apps2SD in tow. Hell, Android 2.2's wildcrazy speed boosts are reason enough to put that puppy on any Android phone within arm's reach.

    We'll be running articles on doing just that for the major phones (Moment, Hero, G1, etc.) when that process is mature.
  3. AlexDeGruven
    AlexDeGruven Yeah, even if the OEMs don't put together official ROMs, the hacking community will be all over it.

    Some of the SDX people have been running JIT installs on the current crop of Moment 2.1 ROMs for some pretty impressive speed gains. Though the speed has been at the expense of stability. Things are getting better pretty quickly, though.
  4. Zanshin I wish people would caveat the Android Police report. Linpack is a terrible, terrible benchmark.

    It's a tight loop of calculations that's ideal for JIT. Real-world performance right now with the JIT that's been in Eclair runs about 1.5x faster.

    I'd expect an average of 2.5X faster with an optimized JIT.

    450% is creating expectations that will blow up in someone's face. Remember, readers aren't technical enough to know linpack's failure as a benchmark.

    Cyanogen and Koush have both posted in the Cyanogen forums cautioning people using linpack and suggesting the development of a real-world benchmark.
  5. Ratnok, Denver, CO @Zanshin- great point. Even so, 2.5X faster is still awesome. Especially on snapdragons!
  6. Hooty Let's not forget that the Nexus One also has a FM transmitter. How about enabling that feature?
  7. QCH
    QCH I'll take a 100% improvement on my Motorola Cliq... Of course I'm STILL waiting on Android 2.1. :(
  8. Snarkasm
    Snarkasm Hooty, 2.2 should also bring with it native support for FM radio hardware in devices that have it now. HTC implemented their own solution on the Desire, but 2.2 will give that ability to all Android devices, regardless of OEM or Android implementation.
  9. jon Will it have divx?
  10. Gambot Will it run Crysis?
  11. Michael James Swan Loving the Android POV. I have not got an Android Phone yet but I am highly tempted to get one now.

    I currently have an Iphone 3GS and I hate that Flash is not supported. I was thinking about the Ipad but with no Flash, it's a no go zone.
  12. Shiva As a new Motorola Droid user who is still wowed by what it can do, I am happily waiting for this firmware upgrade. Love getting wowed!
