Description

Android platform documentation says JDK 7 or later.

http://cordova.apache.org/docs/en/latest/guide/platforms/android/index.html

In fact, the default/sample project build throws a java.lang.UnsupportedClassVersionError in :transformClassesWithDexForDebug.

-->>
Exception in thread "main" java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : Unsupported major.minor version 52.0
<<--

When I change to JDK 8, the problem goes away and everything seems OK. (I only tested this with OpenJDK, but suspect it will be the same for Oracle Java.)

If you decide to fix this by changing the docs, be aware that the JDK download link you currently provide offers only JDK 7 downloads.
