Android 2.1: can't run HelloWorld on the Emulator

I'm new in Android. I'm starting with HelloWorld program, but I can't run it on the Emulator. I'm using newest version of Eclipse and Android SDK. I also set up development environment as follows instruction开发者_如何学JAVAs on http://developer.android.com/index.html.

Does anybody have advice for me?

OMG!!! My problem is nothing :)) i must wait the emulator in a long time after that my program will be loaded. I watched a tutorial clip on YOUTUBE and i saw the boot screen of the emulator is as like as the emulator in my machine. Thanks all for help!

Do you get any errors?

if this is your first app, its probably to do with setup and enviroment. Whats your system spec?

I found running the install process - you have to make sure you follow the installation process in a good sequence. Eclipse, android platform. Java enviroment then ADT plugin.

the AVD Manager updater should have taken a long time to get everything you need when you run it. If it failed - There is a little check box in the settings of the AVD manager that allows you to force download the HTTP -

But as long as you've got the lot, and your building a 2.1 file. Also, the first time you run the emulator, it'll sit quiet for a worrying amount of time. Just make tea, watch TV - google kayden kross and it'll be fine.

Make sure you create an emulator image (AVD) or you won't be able to run it.

also for other newbies , just right click the project and say "debug as -> android" .
