Apk build error

I am trying to build android apk for my application. I have successfully installed java jdk1.7.0_79, using these Instructions (in highest voted answer). My O.S. is Ubuntu 15.10.

When I build apk using both the Jdk (jdk1.7.0_79/80) I get same build error

:app:transformClassesWithDexForDebug

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

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
 com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/usr/lib/jvm/jdk1.7.0_79/bin/java'' finished with non-zero exit value 1

Note 1) I have updated jdk location after installing each jdk(by removing previously installed jdk), I have no problem in java installation.

2) I have previously resolved rendering error in layout which is also same as "Unsupported major.minor version 52.0" by unchecking Android API 23:N(preview).

Check if your build.gradle(Module:app) has compile

eg: compile 'com.android.support:appcompat-v7:23.4.0' compile 'com.android.support:design:23.4.0'
