Subject [jira] [Commented] (CB-1185) When Application is placed in background and resumed, the UI is frozen
Date Tue, 13 Nov 2012 15:26:12 GMT

    [ https://issues.apache.org/jira/browse/CB-1185?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13496248#comment-13496248

Matthew M commented on CB-1185:
-------------------------------

Just a quick note to say that we worked around our particular issue by preventing our AJAX
requests from even starting if a network connection is not present. (Note: <CB-1807>).

It seems unlikely that we were experiencing the same issue as most of the others here who
don't seem to be doing AJAX requests. But if you ARE doing an AJAX request at any point when
a connection is not present, or has been dropped or temporarily lost, the app can present
the same UI freeze symptoms upon resume.

> 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
