[2011-08-21 10:08:48 - HelloAndroid] emulator-5554 disconnec开发者_开发问答ted! Cancelling 'com.example.helloandroid.HelloAndroidActivity activity launch'!

try to clean the project and re-build

I had the same error a few days ago after installing new updates for the AVD in the Eclipse "Android SDK and AVD Manager" on my pc (OS: Ubuntu 10.04). This stopped the AVD from working with the same error message as you give in the second sentence.

I ended up uninstalling 1) the Eclipse software and the 2) "Android platform and other components" . Then I reinstalling the software. This worked for me.

I am not sure if this will help you solve the problem, perhaps you have already done the same?
