======= Fixed ============================================== ============================

By finding some materials, I know I need to set up the system environment variables, add "C:/marvin/Android/android-sdk_r11-windows/Android-SDK-Windows/tools" to system path. restart eclipse and rerun helloandroid application.

 

Someone said if you met this problem, you cocould renew an emulator or take several minutes for waiting.
