It may be in some areas, but I can't recommend it without the forms support that I mentioned at the beginning of the thread. On further investigation it seems as if the Foxit PDF viewer supports far more of the JavaScript object model and it is available on iOS and Android. I wish Adobe would try a little harder to make the Portable Document Format (PDF) portable across its various offerings. This lack of mobile support for simple operations in forms through JavaScript such as showing and hiding fields is making PDF forms useless in certain industries.
I agree with you michael that the Adobe Reader Android App lacks this basic function of Show/Hide field which renders most of our existing forms unusable in mobile environment. If there could could have been a work thru in Acroforms, that would have been welcomed.
