Marcos, I just had a quick look at the code for unav, and I think it would be very useful if you could instrument the JS code with a few debug logs to try and figure out what’s going on for users who can observe the freeze.
Could you get someone who can reliably reproduce the issue attach the corresponding log file? It should be at /home/phablet/.cache/upstart /application-click-navigator.costales_navigator_0.11.log Is it possible that the index.html page is ever reloaded, thus leading to more than one call to watchPosition() through the lifetime of the app? Also, I’m not really sure what purpose the "if (prev_run <= $.now())" test serves. According to the W3C spec for watchPosition (http://dev.w3.org/geo/api/spec-source.html#watch-position): « the successCallback is only invoked when a new position is obtained and this position differs significantly from the previously reported position ». So presumably if you get two success callbacks in a row, it’s because the position has changed enough that you really want to update the position on the map anyway. ** Also affects: oxide Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu WebApps bug tracking, which is subscribed to Oxide. https://bugs.launchpad.net/bugs/1462664 Title: Geolocation app is freezing in a few mobiles Status in Oxide Webview: New Status in uNAV: Confirmed Bug description: Hi! With the app GPS Navigation a few users have problem with a freeze issue, because of 100% CPU usage or heavy swap usage (I don't know, because I can't reproduce it. For some users, it is working perfect, for other is freezing after a few minutes. You can see here the user reviews: https://uappexplorer.com/app/navigator.costales The code is here: http://bazaar.launchpad.net/~costales/unav/trunk/view/head:/www/js/geolocation.js It's just a simple HTML5 geolocation code. Even I added a reject control for more that 1 request by 800 microseconds. I think it could be the GPS doing a lot of request by second or the web container is freezing waiting for GPS.
