failed to run Hello World project with launching emulaotor

When Start running Android Hello world project, the eclipse launches emulator, but seems hello world project was not running, the emulator开发者_如何转开发 showed "Android" in the middle of the scrren, I tried Android 2.2 emulator, I heard some people opens emulator first then run the project, Havn't tried that yet. is that a correct way?

The Android emulator is slow. So be patient and eventually it will show you a home screen and your project will run.
