Android sample hello world application

I have followed your hello world project , build was successful, still the apk file is not created under below path.

project path>/app/build/outputs/apk

I have run the green triangular button , but displaying "configuration is still incorrect , Do you want to edit it again" error popup is displayed. I was not able to setup emulator as while installing studio, intel HAMX is not properly installed.

Configuration is still incorrect meant some of you code is not valid or something error, you can try to invalidate cache and restart (File>Invalidate Cache/Restart> Invalidate and Restart) and rebuild again. if it doesn't work please try to create new project and try to run without change anything to make sure that the problem is Tools's problem or Project's problem.
