**Hello Community,**

I am a dev team leader. One of my great developers is working on a complicated app on iOS and Android. He is still facing an issue on how to develop one functionality. That's why I am asking here so that I can be of an assistnace to him. 

In the below image, we want when the user touches/taps on a specific part of the sheeb, a new content should be retrieved from our backend via API. 

**I have two questions:** 

1. Should we have the below image be cut to more that one image file (each part is a separate image file) then we can bind them in code? Or is it better to keep it as one file?
2. Could you please refer me to any method, class, sample code, or any other resources on how to create similar funcationality on Android and iOS?

I appreciate it if you can refer me to similar code samples as well.
