726201 - Lazy load about:home

Status: VERIFIED FIXED

(Firefox for Android Graveyard :: General, defect, P2)

Description

[Sriram Ramasubramanian [:sriram]]

If there is no session to restore, the about:home is kicked off from the Java itself and loads on startup. This takes around 1 to 1.5 seconds usually. Instead, we can wait for the Gecko to ask Java to load about:home. Thereby we won't be stalling the main thread on startup, and the app comes up much faster.

This will be a balancing act. We don't necessarily want to wait for Gecko to be ready before showing the AboutHome page. That could take >3 seconds. We _do_ want to make sure that the AboutHome code is not delaying the initial UI from displaying, but AboutHome should load ASAP afterward.

As a part of the patch in bug 725932, I am lazy loading the about:home if we are not doing a session restore. This happens when Gecko is loading in the background (or probably I might need to profile it a bit and move chunks of code to do it ;) ). This way, we don't wait for Gecko, but still lazy load about:home.
