[Solved]Unable to build with google AdMob plugin

I’m trying to add AdMob banner in my android game but the game won’t compile. This is what i have done:
I have 23.0.2 android SDK installed with Google Play Services
I’m using Unity 4.52f1
I downloaded this official (i guess) google plugin: https://github.com/googleads/googleads-mobile-plugins/tree/master/unity
I have done this step from plugin manual:

And now Unity won’t compile. The error is:

OK The problem was in JDK i had JDK 7 only 64bit but needed JDK8 both 32 and 64
