Why does deviceready take a second to load on Android?
Hey
I just tested Cordova with the latest JS on Android and I'm noticing a
pretty solid lag in how long it takes for things like the platform
name, version and UUID appear. Was there a recent change to
deviceReady that causes it to be noticeably slower than it used to be?
I'd figure that asking is faster than reading through the commit logs
and debugging this.
Anyone know?
Joe

It looks like Bryan was correct; the reversion of the change he linked,
which was done to fix mobile-spec on ICS, fixes this problem as well.

createElement would fix that

I bet it has to do with this change to mobile-spec.
By injecting the script tag, cordova.js does not load until after the DOM
has rendered.

It might be the time spent doing the plugin loading, but I'm not sure. We
should instrument some of these launch steps to see how long they each take
and keep an eye on them over time. Eventually and in an ideal world, the
timings could be collected by the CI server so we can spot any substantial
increases and figure out their cause.
