Restart your Mac. As soon as it turns on, even before you hear it go bong, hold down Cmd+S. The system will boot showing a lot of text. If it doesn't and you see the Apple logo, you've waited too long. Reboot and try again. When at the prompt type  fsck -f . If changes are successfully made it will repeat the process then say "Modifications have been made". Then simply type in  reboot  and you should be able to partition your drive successfully. http://hints.macworld.com/article.php?story=20080120064811786

N.B.:This is required to remove the apps already present in emulator...If u want ...

1. Create Helloworld.java: package org.apache; public class HelloWorld { public static void main(String[] args) { } } 2. Compile java: javac -d . -g Helloworld.java 3. Package Java Into a temporary jar jar -cvf Temp.jar * 4. Use DX to generate classes.dex from Temp.jar dx --dex --output=classes.dex Temp.jar 5. Use aapt to create new Jar (CmdLine.jar) suitable for use with Dalvikvm aapt add CmdLine.jar classes.dex 6. Push Jar to folder: adb shell     mount -o remount /system     exit adb push CmdLine.jar /system/framework/ 7. Restart: adb reboot
