Acrobat Reader mobile apps for iOS and Android do not support the special type of PDF called static/dynamic XFA form.
Please see the following Adobe LiveCycle blog that was written in year 2014.
We are not aware of any change of plan in the near future.
Sorry for the inconvenience caused.

What can the creator of a XFA dynamic form created in LiveCycle do so people using Acrobat Reader mobile apps can access these PDF documents? I am also am running into this problem working for a government agency and most of our clients have gone to using Chromebooks. Any suggestions would be greatly appreciated!
