@Kuimo75 Hi, there.

I was also encountering the same strange error, but at last I was able to build my first APK!!!

STRANGE SOLUTION :

  1. Uninstall JDK 9 and download JDK 8 from here:- http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

  2. Also remember to set the keystore in the publishing settings carefully and don't forget to set key.

It worked for me and I hope it will work for you too.

After trying out other *solutions, only this worked for me.

Now my setup is - Unity 5.6.4.f1, Android API level 16, Java 8_151 (Of course!), Win 10.

you probably want to make sure that you have scenes set up in the build settings menu, in that screenshot it looks like you havent added any scenes and if you don't add scenes then nothing will build.

That looks like a different build error though, I would double check that you have the android sdk/ndk and all that set up in the external tools section of the project preferences. If thats not it then make sure your apk name is set up in the player settings menu.

if all that fails then im not entirely sure what would be wrong, you can take a look at the steps to get set up with android development in unity here.

if you were able to make a build before but you cant now, you might try iterating the version number, or uninstalling the original build before trying to make a new build
