I am trying to build the android app from kivy application. I used the Buildozer image as given on the kivy.org downloads page, but that Virtual Machine never runs on the virtualbox. Is there any other way to do this. I have seen some SO questions regarding this but they seem to be very old and hasn't been of much help till now.
You need to provide information about what goes wrong when you try to run the VM - nobody can help if we know only that something doesn't work.
Alternatively, you can make a new VM with any linux distro (a recent Ubuntu is a good choice) and install all the dependencies. Kivy's VM is nothing special except that it has them preinstalled.
