Subject [jira] [Commented] (CB-1185) When Application is placed in background and resumed, the UI is frozen

Adam  commented on CB-1185:
---------------------------

Are you doing phonegap build or running the project locally? If local, you can add it to the
onCreate in your Activity, after super.onCreate

 super.setBooleanProperty("keepRunning", false);

I'm still doing that and don't think it fixed anything. It seemed my real fix seemed to be
clearing all timers in my javascript in my handler for the "pause" event...

function onDeviceReady() {

                document.addEventListener("resume", onResume, false);
                document.addEventListener("pause", onPause, false);
                document.addEventListener("backbutton", onBack, false);

               

            function onResume() {
//start the timers again
            };



            // Handle the pause event
            //
            function onPause() {
                //clear the timers
            }

> When using PhoneGap 2.0.0 on ICS or JellyBean, the application freezes up after you set
the app to the background or turn of the screen. After around 3-7 seconds, the application
unfreezes and pretty much causes a panic and usually crashes. No error reports have been submitted.
> Here is how you re-produce the issue:
> 1. Download Untappd - V2.0.4(https://play.google.com/store/apps/details?id=com.untappdllc.app)
> 2. After logging in stay on the Friends tab
> 3. Turn the the screen off and wait about 3-7 minutes
> 4. Turn the screen back on, and the interface should be frozen.
> Another possible path to re-producing the issue:
> 1. Download Untappd - V2.0.4(https://play.google.com/store/apps/details?id=com.untappdllc.app)
> 2. After logging in stay on the Friends tab
> 3. Go back to the home screen then use other apps for about 3-7 minutes.
> 4. Go back into Untappd, and the interface should be frozen.
> When the app is frozen, native menu buttons will not nor any options in the UI. 
> Would love to see if anyone can replicate this. I've tested this on Jelly Bean 4.1.x
on a Samsung Galaxy Nexus, but users have been having this problem majority on ICS (4.0.x)
> Thanks,
> Greg
