I want to do some cleaning in my Google Play Developer Console by deleting
a game service which has currently two linked apps (one for debug and the other for the release). This game service was published by mistake and now, I get this message which never changes :
Publishing of your game in progress...
I don't see any delete button in the Google Play Developer Console and the corresponding project has been already successfully deleted on https://console.developers.google.com.
No, you cannot delete the application once you have published it in Google Play. Google will keep all the apk files.
The Delete button only works for unpublished version of your app. Once you published your app pr a particular version of it, you cannot delete it from the Market. However, you can still unpublish it.
