Sorry if I'm asking this the wrong way (if I am, let me know what I should be doing instead.) The site warned me not to leave this as an answer and I don't have enough rep to add a comment, so I'm doing a new post.
Basically, I am having the exact same problem as this poster: Getting error message "Android sdk content loader stuck at 0%"
That is, when I open Eclipse it shows the message "Android sdk content loader 0%", and so my projects refuse to build. But I have tried ALL the responses listed there: turning off build automatically, cleaning all projects, deleting my debug keystore, deleting the adb process in the Activity Monitor (I'm on a Mac), switching workspaces, renaming projects, shutting Eclipse down and restarting it. I also made sure to install the latest version of the SDK (4.2, API 17, Jelly Bean). My phone was not plugged into the computer in the first place. I even deleted and reinstalled the ADT. And I STILL get the same problem. Please, somebody, tell me what's going wrong and how I can fix it.
