App not running with an exception in android studio

When I try to run my very first app I get an exception. I've tried to re-install android studio and update java but to no avail. The error I get in the console with --stacktrace on is: FAILURE: Build failed with an exception.

  • What went wrong: Execution failed for task ':app:packageDebug'.

    Implementing class

  • Try: Run with --info or --debug option to get more log output.

  • Exception is: org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:packageDebug'. at

It'd be a lot easier to see what's going wrong if you posted some of your code or even your entire project on a website like github. Let me know if you can do that, and I can try to help. Thanks

It's literally an app with just a blank activity. All I've done is change the name of the app.

What happens when you hit the "Make Project" button (it's to the left of the Play/Run button)?
