Hi Sahil,
Unfortunately, you are out of luck with the requirement to use XFA-based PDFs on mobile devices as Reader mobile does not support this type of PDF.
What Adobe customers do is to use either what's called HTML Forms or Adaptive Forms. They are available in AEM Forms which is the successor for LiveCycle. AEM stands for Adobe Experience Manager.
The functionality is currently not available in Interactive Forms.
Regards,
Juergen
