Where is my apk file?

I get a- BUILD SUCCESSFUL message after executing:
meteor build …/mew --server=https://masseducationweapon.com

BUILD SUCCESSFUL in 1m 37s
44 actionable tasks: 44 executed

Where my apk file is supposed to be there is a .tar.gz file, is that file my .apk?
Should change the extension to .apk?

Thanks
