Did you make sure to also handle the Android Native part of the functioanlity. Best would be to have a detailed look at the complete sample in regards to the capture screen feature together with the documentation and make sure that first the concepts are clear and then you change the code according to your needs.
Please also make sure that you handle the permissions accordingly - also compare the sample app and documentation in order to make sure to not forget anything.
Also, I added the function below into 3dmodelsandgesturesinstanttracking.js of 05_InstantTracking_3_Interactivity folder. This function is taken from 10_BrowsingPois_6_Bonus-CaptureScreen at github.
Alhtough the example app provided workes fine (10_BrowsingPois_6_Bonus-CaptureScreen), when I try to implement capture screen into Instant Tracking: Interactivity feature it does not ask for permissions neither prompts the share menu, thus not saving the photo. Seems like I am missing something, can you direct me through the process?
Thanks in advance,
