View a photo in the gallery, then go to the homescreen. Then go back to the app. The photo you were viewing does not display. If you swipe over, the next one displays and everything works as normal. In onresume, probably something needs to happen to display the photo.

I had a similar problem with the RadListView. The solution was call the RadListView function "refresh" inside the callback of resumeEvent

Detect "on resume event" and refresh(); Ex: const applicationModule = require("tns-core-modules/application");

function pageLoaded(args) { var page = args.object; ... ...... your code ........... ... //Detect Refresh resumeListener = (args) => { console.log("The appication was resumed!"); //refresh your gallery page.getViewById("gallery").refresh(); }; applicationModule.on(applicationModule.resumeEvent, resumeListener); }
