阅读更多关于 Android Development Device

问题 I'm looking to get a device (phone, tablet, etc.) for developing Android applications. I know I can use the emulator to get me started, but I feel like that will only get me so far along.

Other option is ebay. All attendees of google i/o got moto droid as a gift.

问题 Adobe are launching Flash Player 10.1 in the first quarter of 2010, this will provide consistent runtime across desktops and mobile devices (so I assume if it was built for the web it will work on the mobile).

Is it possible to push content only to recipients within a certain distance? (ie. based on signal strength or similar) Can anybody recommend a piece of software that can do some or all of the above? If necessary we could program a custom solution ourselves (.NET), but I'm sure there

But my unserstanding is that this can be used to track the mobile location if required but mobile apps or Google maps uses the satellite approach. Right ? Matej P. It's a bit inaccurate
