Given only an APK file, how can I find out the developer of a non-market Android application?

A "non-techy way" would be, given the package_name, doing a web search on it. Chances are it's available on some store, which then would give you the developer's name.
A different way is, as indicated by ottucsak's answer, extracting it from the certificate. The way to do that is described here, and basically involves the following steps:
- unpack the
.apkfile. As that's a.zipin its structure, unpacking would mean unzipping. - use
keytoolto view the certificate:
keytool -printcert -file META-INF\CERT.RSA - in the output, check for the "Owner" and "Issuer" lines.
It isn't really is possible. However there is a workaround. If you have got the package name of the apk you can see the developer name. Something like this: com.<developer_name>.<app_name>. Example: com.google.drive. If you don't know the package name you need to extract the apk and then the package name is somewhere in the android-manifest file.

Thanks, I have the package name and the apk too. It is a reverse engineering challange and I have decompiled into jar, but the developer's name isn't in the source files so I figured that I will have to look elsewhere to find the answer.– fuzboxzCommented Apr 15, 2015 at 8:48

Just checked it, unfortunately this isn't correct. Is there any other field in which the developer's name/username/signature can be found?– fuzboxzCommented Apr 15, 2015 at 9:15

You could try google searching for the app/package name. Maybe then you can find the developer. Commented Apr 16, 2015 at 7:36
You can use the Java Keytool to pull information about the developer.
keytool -printcert -file <extractedFile.RSA>
I found the developers name in the app's signature in the *.apk/META-INF/CERT.RSA
