Aws iot core and greengrass for Android devices

We are looking into iot device management solutions and are analyzing the AWS iot core and greengrass among other products. Our iot devices can be of different types and we will also have zebra devices on android. The AWS iot documents mention that greengrass is supported on Linux and windows. Can we effectively use it for Android devices also? Also we are looking at fleet provisioning of the iot devices. Is this supported for Android devices? Thank you.
