解决方案

I got this same error while running my application. In my case actually problem is that custom_button.xml drawable file present in drawable-v21 folder not in drawable folder, which causes the error, I removed it by copying it into on drawable folder I think in your case btn_register_background.xml file present In something folder like drawable-v21 or drawable-v24 or anything like that, try copy btn_register_background.xml into drawable folder.
