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
Great topic!!
After reading all answers. I have found a simple solution and It work fine on windows 7.
I created a file "eclipse_start.bat" with this simple command lines:
cd /d C:\eclipse (the directory where is the eclipse.exe file)
eclipse -clean -refresh
cmd
Every time i have to launch Eclipse simply I launch this file so the program start without problem.
I tried also another solution. I added this line in the file "eclipse.ini" before all other line
-clean
-refresh
In this way I can launch directly Eclispe with the same result but in a more cleaned way.
Thanks to everybody!
