Repair HFS+ when your BootCamp is error

1. Restart your Mac.
2. As soon as it turns on, even before you hear it go bong, hold down Cmd+S.
3. 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.
4. When at the prompt type fsck -f. If changes are successfully made it will repeat the process then say "Modifications have been made".
5. Then simply type in reboot and you should be able to partition your drive successfully.

How to remove default/preloaded applications like browser,camera,contacts...

Suppose u have developed a new contact application which is much better than the preloaded contact application in android..so when u want to install it eclipse will throw u bunch of error saying "Please uninstall the contact application first by adb uninstall "package name".

When u tried to do that...Alas...it did not work...saying FAILED

The reason for this is that u don't have the root access and u have only read only access..So to change the access and remove the contacts(any application) follow the below instructions..

1. Start your emulator
2. Execute "adb shell" in on terminal from SDK_ROOT/tool folder
3. Mount your system folder with read/write permission
   

   
   mount -o remount,rw /dev/block/mtdblock3 /system
   

4. Go to system/apps folder
   

   
   cd /system/apps
   

5. Remove APK
   

   
   rm defaultapp.apk
   

 

Bingo Check your emulator.The default application is gone.Now u can install your application with eclipse.
N.B.:This is required to remove the apps already present in emulator...If u want to remove some of the application u've installed then just do

adb uninstall yourpackagename

or

adb shell
cd /data/app
rm yourapp.apk

So enjoy Being an Android Programmer........
