Had the following error in Eclipse after installing Android 5.0 (SDK 21)
"Loading data for Android 5.0" has encountered a problem.
Parsing Data for android-21 failed
unsupported major.minor version 51.0
I am still facing the same problem on mac, and now as in the few answers try Java 1.8 where I found the latest version of it. Old is not available. I already have updated Java but I don't know what's wrong with it.
