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 solved the issue with this (from your eclipse folder):
eclipse -clean -refresh
I followed this url: http://tekhoow.blogspot.com.es/2013/06/eclipse-stuck-at-android-sdk-resolving.html (but the eclipse command was enough for me)
There is also another stack question with the same topic and say the same: "Clean all projects in your workspace and restart Eclipse to solve this problem." How to Resolving error markers Eclipse Android SDK
