Unsupported Major.Minor Version 52.0 in My App

Unsupported major.minor version 52.0 in my app

I face this problem too when making new project from android studio.

I've been able to resolve this by downgrading buildToolsVersion in app gradle setting:
change {module-name}/build.gradle line

buildToolsVersion "24.0.0 rc1"

to

buildToolsVersion "23.0.3"

@Edit:

In Android Studio 2.1 Go to File-> Project Structure->App -> Build Tool Version. Change it to 23.0.3

Do the method above, only when you are using java version 7 and for some reason do not want to upgrade to java 8 yet.

Hope this helps

Unsupported major.minor version 52.0 in commande

I think you need to update the JAVA_HOME environment variable to the JDK8 installation directory. Make sure the PATH environment variable points to the same directory too (in this case remember to add a final "/bin" to the path).

If you see this answer, you will note that 52 means it needs Java SE 8 or superior.

What does 'Unsupported major.minor version 52.0' mean, and how do I fix it?

You don't need to change the compliance level here, or rather, you should but that's not the issue.

The code compliance ensures your code is compatible with a given Java version.

For instance, if you have a code compliance targeting Java 6, you can't use Java 7's or 8's new syntax features (e.g. the diamond, the lambdas, etc. etc.).

The actual issue here is that you are trying to compile something in a Java version that seems different from the project dependencies in the classpath.

Instead, you should check the JDK/JRE you're using to build.

In Eclipse, open the project properties and check the selected JRE in the Java build path.

If you're using custom Ant (etc.) scripts, you also want to take a look there, in case the above is not sufficient per se.
