1. First, when "Android SDK Content Loader" is loading at 0% then kill adb and eclipse process at your terminal.
# ps aux | grep adb
# kill -9 XXX
where XXX is adb process id.
#ps aux | grep eclipse
#kill -9 YYY
where YYY is eclipse process id.
2.Move the Android SDK folder to be temporary folder.
#mv android-sdk android-sdk-backup
3.Execute the Eclipse, this time it will ask for the SDK folder. Just point to another SDK folder. (I downloaded another SDK)
4.When Eclipse has finished all loading process. Move the temporary folder back to normal.
#mv android-sdk-back android-sdk
5.Then set the preference path of the SDK back to normal setting. It should work again.
