I am aware that other people have tried to resolve this issue but have thus far found a suitable answer.
The error is, on start up, eclipse gets hung up on \"Android SDK
I have a simply solution without code. Stop the process "resolving error markers" using the red button, then uncheck Build Automatically (Project -> Build Automatically), close Eclipse and open it again. Check again Build Automatically.
Sometimes it happen again, then I do this same process. Boring, but it works.
