I was working with Ionic and I wanted my project to generate the APK to be able to upload it to Play Store , I created a platform Android with the ionic cordova platform add android command and it worked. Then I wanted to create the APK with the ionic cordova build android command, and it also worked for me, but it did not generate either the APK or the address. Where he puts it just comes out as in the image I put.
If you want to create an apk to test it on your cell phone you can do it using the command (Latest version of IONIC Cli):
$ ionic cordova run android --device
Remember that you must have your Mobile connected through USB and enabled as a developer.
If what you want is to create the apk to upload it to the Play Store, you should already do a slightly longer process that is clearly explained here link , remember that you must also have an Android developer account, which if not bad, costs around 30USD.
