Your error message is telling you it cannot find a target ARM device for deploying your application. In this case, it can't find either a virtual device or a physical device connected through a USB debugger, so it is asking you to create a new one.

If you are able to connect to a virtual device through Android Studio, then you should be able to locate that same device and load it into your project configuration in Qt Creator. Did you configure a kit (Projects -> Manage Kits) for Android in Qt Creator?
