Unexpected top level exception: bad class file magic, in Android

Question

I am trying to compile my android program via command line, using ANT. And the code compiles fine. But when the target -dex is executed, I get the following error:

 [dex] input: /Users/aditya/Desktop/workspace/Java/Play/bin/classes
      [dex] input: /Library/Java/Android/tools/support/annotations.jar

I get the same kind of error with Gradle and IntelliJ.

I am not able to figure out the actual problem whats happening. Please Help. I am using Java 1.8 to compile this program. Is there no way of using Java 1.8 to do this? Is it necessary to use 1.6? If so, how should I use Java 1.6?

It looks like you are using JAVA 8 to build your project. Current version of dex is not working with Java 8. Try to build with java 7. — Alexander Mikhaylov, Jun 16 '15 at 09:02

Check the version of Java you are using to compile your classes.

You need to be using Java 6 or 7 for Android development. Java 7 support was added more recently and its functionality is limited, so use 6 for maximum compatibility.

the reason of this problem is java version. It should be jdk 1.7 or less. uninstall your 1.8 version and install 1.7 and change the path in environment variables.
