Answer 3

The only one reason for Unsupported major.minor version 52.0 in eclipse is API Level 24

So please do following things to resolve Issue in Eclipse :

1. GO To Window menu
   2.Open Android SDK manager
   3.Check is API level 24 is installed any Platform
   4.If YES Please Uninstall this API level 24 Packages.
   5.Clean Project and Run Again.

And its Work fine.

Answer 4

your code might has been compiled with Java Higher version(i.e. 8), while you are trying to run it with Java Lower version(i.e. 7). Note that Eclipse has it's own compiler and does not use the one from the JDK and most probably it is configured to use Java Higher version(i.e. 8). Check you eclipse compiler preferences.

Answer 5

Adding the below line in project.properties and setting Java to 1.7 solved the issue to me.

sdk.buildtools=23.0.3
