Please help me, I\'m having serious trobules with Eclipse for the second time. I\'m following a guide and in these last days my Eclipse used to work fine (and was heavy 600 mb),
There are likely workarounds for this, but I think I suggest just downloading a fresh Android bundle (with all the correct updated software), and install it fresh.
I have had experiences where something goes wrong in the tools update, and found the simplest way to correct is to uninstall my existing tools and start fresh. It is easy to install the bundle, and you will know you have all the correct packages and software installed.
You will spend a bit of time trying to debug your install, it will be quicker to install a fresh instance.
I had a similar problem. The only way I could make it work was to completely uninstall Eclipse and Android SDK and reinstall again.
I self resolved by switching to Android Studio IDE
