sorry to hear you are having these deployment troubles!
I guess there really is no better way than using the other Qt Creator version at the moment.
As for the RippleDrawable class not found exception: I also experienced this error in the past. As far as I know, it is only printed on older android versions and can be safely ignored. I don’t think it is responsible for the weird behavior of your entities.
To make sure you don’t have an error in your code: If you can narrow down the code part that is affected, I can see/try if the code works on my android phone.
