Hi Ratnadip,
You can build the applications through SAP Mobile Platform and can deploy those apps through SAP Afaria to all the devices.
Moreover, you can use Eclipse tool to build the enterprise applications and can use the .apk file to push those apps to the devices through SAP Afaria.
Please take a look at this documents for better insight SAP Mobile Platform – SAP Help Portal Page
Kind Regards,
