Answer 1

if you only have folder 1.6.0.jdk then go to this link and download and install jdk 1.7. then find your java folder in this path

/Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home

Answer 2

The Exact Fix for this Issue (Android Studio Users on Mac)

If you have already upgraded to Java 8, please note that the JDK location is now within /Library/Java compared to Java 6's location /System/Library/Java. So to fix this problem, Right click on the Project folder > Project Structure > SDK Location.

Then change JDK location to

/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home

If you have installed a different JDK version (other than Java 8), find out the path using the java_home script first and use the output. Just run,

/usr/libexec/java_home 

Answer 3

The solutions on this thread are not valid for the same error in Android Studio 1.4 . The preferences menu, for example, is gone. Below is the solution for Android Studio 1.4 running on Ubuntu 14.04.

To solve in Ubuntu 14.04+ and Android Studio 1.4+, you need to go to

File -> Other Settings -> Default Settings -> Build, Execution, Deployment -> Compiler -> Java Compiler -> Project Bytecode Version

This drop-down will be empty by default.

Set to your preferred JDK, in the case of the screencap below, 1.8 .

Voila, your project will compile.
