下 载:Android2.2 SDK
此外，Adobe的Flash Player 10.1 for Android也开始正式提供beta下载，但需要使用2.2版本的Android访问，看来只有少量使用2.2的内部人员才能参与测试吧。下载:Adobe的Flash Player 10.1 for Android
Portable Hotspot and USB Tethering
Froyo obviates the need for an application like PdaNet or rooting Android to use your phone's data connection to get online with your laptop. You can get your laptop, iPod touch, or iPad online via Android 2.2 by turning your phone into a portable hotspot ala the MiFi. Enable your portable hotspot in the Wireless settings area. Name your access point, optionally assign a WPA2 PSK password, and any Wi-Fi enabled device in the area will be able to see and connect to it. I'm not sure what any provider-imposed limitations on this are, but up to 8 devices can connect to the Froyo access point.
USB tethering—that is, using your phone as a modem to get online—is available on Windows and Linux (not the Mac). Windows XP users have to download a driver; Windows 7, Vista, and Linux users are good to go by just enabling tethering on the phone and connecting it via the USB cable to your computer.
Select Text on Web Pages, in Email
While it's not as well-implemented as the iPhone OS's select text feature is, in Froyo you can now select text that's not in a text field and copy it to clipboard. Gmail and the browser are the only two apps I've seen this available in, but hopefully there will be more to come.
On either a web page or in email, to select text, hit the settings menu and tap "More." (Yes, already it's too many steps.) Choose "Select text" from the menu, as shown.
You'll notice a little mouse pointer on screen. Tap and drag your finger around the text you want to select, which will turn pink, as shown. When you're done, text gets copied to the clipboard automatically.
This process is too buried in the Settings menu and involves too many steps right now, but it's better than nothing.
Flash Support
A beta of the Flash 10 browser plug-in for Froyo is available in the Android Market; search for Flash there to download it. It works just the way you'd expect. With the plug-in enabled, you'll see Flash-based ads and embedded video and be able to play games. I played Google's homepage Pac-Man on my N1, and with the Flash plug-in enabled I could hear the game's music (which is the only part of it that involves Flash). I could play YouTube videos on-page. However, despite some tinkering, I couldn't get a Hulu or Vimeo video to play. On Hulu I got a "your device isn't supported" message, and Vimeo told me I needed to download Flash 10. So, Adobe's Flash 10 plug-in for Android 2.2 is indeed beta.
If you don't necessarily want to see every Flash bit of every web page, you can change your settings to enable Flash on demand. To do so, in the Browser's Settings panel, tap "Enable plug-ins." There, if you choose "On demand," when you visit a page with Flash content you have to tap it to activate the Flash plug-in. I haven't done much Flash testing yet to get a handle on battery usage and performance, but I imagine the "On demand" setting will be a battery-saver for Flash users.
Gmail Auto-Advance
In the native Gmail client, you can easily move to older or newer conversations using left and right arrow buttons at the bottom of an open message. You can also configure Gmail to auto-advance to older or newer conversations when you delete or archive a particular message. To do so, in Gmail's settings, tap on "Auto-advance."
Twitter Integration
Most of my friends are on Twitter, not Facebook, so I'm liking that my friends' latest tweet appears in his/her contact card automatically, as shown here under Anil's name. Android 2.1 started this type of social network integration with Facebook, and this is the same functionality. If a user has both a Facebook page and a Twitter stream, the status shown at the top of the contact card is the most recent status update from either network.
My wish: that Froyo had Flickr integration the way that the HTC Sense UI has it on my new EVO.
Drop-out Menus
The Android Google search box—which I use constantly—now has a menu that drops out from the G logo which lets you narrow down your search results by type. Android 2.1 introduced this visual style of menu on people inside Gmail and in the contacts list; nice to see it extend to other UI controls.
Improved Application Manager
Froyo's Application Manager (Settings>Manage Applications) has a nice new tabbed interface which lets you see apps by what's been downloaded, installed, what's running, and what lives on the SD card.
Better Camera Controls
The camera controls in Froyo are much easier to get to and they flip based on the phone's orientation. In 2.1 you had to slide out a panel to change camera settings. In Froyo small icons always line the side of the frame and give you one-tap access to zoom, focus, exposure, location, flash, and white balance settings. Zoom isn't available for the video camera, just the still camera.
JavaScript-Heavy Webapps Work Well
I was thrilled to discover that Google Wave actually works on Froyo—well! In Android 2.1, after warning you to use a better browser, Wave would invariably crash your browser 60 seconds into usage. On Froyo, you no longer get the "use a better browser" message, and long, involved waves load without crashing. Hallelujah! Most likely this is a happy result of Froyo's much-improved JavaScript performance.
编者按：我的hero悲剧了，不知倒还有没有高手做2.2的rom
hero is so sad, any dev to cook a 2.2 rom
