emulator crashes - android-emulator

Question

I am setting up an Android environment for the first time on Eclipse. I have many years of Eclipse experience, but new to Android. This is being done on an Apple Mac Mini, running MacOSX 10.6.3. I am using the latest Eclipse Classic, version 3.5.2. I am trying to get the tiny hello world program running.
When I run it, I get the following in the console window of Eclipse:
[2010-06-12 13:48:08 - HelloAndroid] Automatic Target Mode: launching new emulator with compatible AVD 'Android2.2AVD'
[2010-06-12 13:48:08 - HelloAndroid] Launching a new emulator with Virtual Device 'Android2.2AVD'

[2010-06-12 13:48:19 - HelloAndroid] emulator-5554 disconnected! Cancelling 'com.example.helloandroid.HelloAndroid activity launch'!
The emulator crashes with the following info.
I have followed all the instructions for running the hello world sample.
Anyone have any ideas?

Answer 1

I had this exact same problem just now, and when I googled around a bit, I found some threads where people mentioned using Logitech USB headsets, and that unplugging those headsets made the problem go away.
I have a Logitech USB desktop microphone, and sure enough, after unplugging it, the problem went away for me, too. Even though the mic was turned off the whole time!

Answer 2

Having connected the Apple LED Cinema Display, just setting audio input to internal solved the problem for me - no need to set external audio playback aside.
