is any work occurring on this?
i'm aware of two issues w admob, each of which individually make it nearly useless, and together make it completely useless: the first ad doesn't appear, and frame rate drops.
suggest engineering fully read: (as previously posted by Ernest above)
to see if it offers any hints
that thread, and others elsewhere, strongly suggest that it is a "layout issue", where/when the admob view is overlaid on top of an opengl surface view (instead of nestled beside it, as would be possible with a native android java app - where the problem doesn't seem to occur)
is it not also possible that some interplay between the adview overlaying the opengl surface is also responsible for the performance problems? (perhaps somehow interfering with opengl redraws or something?) i obviously have no clue, but just as food for thought
suggested workarounds for the first-ad-not-visible include making the ad view background transparent and/or altering how/when visible/invisible vs remove/re-add the view. Q: if upon fixing THAT problem, has the frame-rate issue been affected as well?
in any case, the implications of that thread, along with reports elsewhere of ppl with native java who DON'T see either problem with "proper" layouts, are that the problem mignt not be on google's/admob's end, but rather resulting from older layout strategies that are no longer appropriate.
worth an engineering look?
