Android app Image tagging

Question

I am working on an android application where user can upload pictures to a stream. The user can also tag the pictures with some labels. The problem is how can I detect the "same" point on an image on multiple screens? what are the possible ways of doing the same ?

Thanks.

Answer 1

You can implement this by cropping the image in a predefined fixed aspect ratio and map x,y as per current view dimensions.
