Why is LogCat showing all items as warnings (orange)?
I had this problem too, I found the solution here - try to update you SDK !In Eclipse go to 'Android SDK Manager' and try to update 'Android SDK Tools' & 'Android SDK Platform-tools'.Note: It may ask you to update your ADT as well...
By the way, it's happend to me when I updated my android device to 4.1 Jelly Beans
Hope that helps,
Cheers!
