Can't run my app on external device(smart phone)

Help, I can't run/test my app on an external device(usb debug). I got several errors.

Error:java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : Unsupported major.minor version 52.0

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.

com.android.build.api.transform.TransformException: java.lang.RuntimeException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_79\bin\java.exe'' finished with non-zero exit value 1

Can anyone help me understand what's happening? Thanks

Maybe it's becuase your android version is low. It means that your cell phone is old.

Thanks for the response.

My phone has Android lollipop 5.1.1. I was trying to use the default API level(Android 4.0 IceCream Sandwich).
