My app crash when it stays in the background for 1 or 2 hour. App crashes for all 3 platform i.e. IOS, DROID and WP. While app running when click on home button and jump to another app then app goes to background. If within 30 or 40 min click on app then it working perfect but after more than one hour click on app then app crashes and not displaying any data.
Please help to resolve this.
