PDF Image Field is not working from Adobe Acrobat app in android.

I created a pdf from & added an image field. It is working good my laptop then I move that pdf form to my android phone & opened it through Adobe Acrobat app, tried many times by taping on image field but it turned to grey colour only. I want to add an image to it from the phone gallery. As I tap on the date field it pop-ups the calendar to add date same thing I want from the image field when I tap from Adobe Acrobat app it open gallery to add image OR camera to take the image.
