* What went wrong:

How can I fix this issue? I am using Java Version 1.7 and Android Studio v2.2.3 and have android-23 in sdk folder.

Answer 1

There is issue in Java and android version. Please reduce your Java version. From Java 8 to minor version.

Java 7 or higher is required if you are targeting Android 5.0 and higher. This is from android official page.

Before you set up Android Studio, be sure you have installed JDK 6 or higher (the JRE alone is not sufficient)—JDK 7 is required when developing for Android 5.0 and higher. To check if you have JDK installed (and which version), open a terminal and type javac -version. If the JDK is not available or the version is lower than 6, go download JDK.

Answer 2

You are trying to run a class compiled using Java 1.8 compiler into a lower JRE version eg JRE 1.7 or JRE 1.6. Your output shows that youre not using Java 1.8
