The project target (Android L (Preview)) was not properly loaded

Question

Recently I upgraded Eclipse along with ADT plugins to Android L priew.

I have the latest Java update as well i.e. Java 8

Answer 1

The problem for that is having different jre versions

I have java 6 and 8 both installed in my system, so I uninstalled java 6 and set path for only java 8.

But remember to restart the system after setting the paths.

Now error is gone while viewing android L Preview
