Is Jdk Required For Android Developement

I have been using Eclipse on Ubuntu for a long time now to successfully run and build android apk's. But i have just realized i had never installed a JDK on my system, only the JRE

Solution 1:

According to System Requirements --> Development Tools in the below link

http://developer.android.com/sdk/index.html

JDK 6 (JRE alone is not sufficient)

Note: The Eclipse ADT plug-in requires Java 7 if your compilation target is the L developer preview.

Solution 2:

Android sdk has embedded jdk .
