I'm trying to build an android app using visual studio community 2015. Basically right now, I'm just trying to build a test app so that I can check the IDE is working perfect for building my main app! But when I'm trying to build the app, it's showing me errors. Here is the output error message in VS -

This is the full error message output in VS. Please help me to fix this issue and build my app successfully!
From the error message, you are getting Unsupported major.minor version 52.0 error, which means you are using certain library, which requires a min version of Java SE 8.
So to fix the problem, you need to update your local JDK to at least 1.8 and configure Tools for Apache Cordova to use it. You can find the setting under Tools->Options->Tools for Apache Cordova->Environment Variable Overrides->JAVA_HOME.
