Re: [Simple-support] Android performance - strange profiling

[Rangel R. <ran...@gm...>]

Hmm I seem to have sent my response to a personal email, instead of the
list.

I tested this on other Android devices and the emulator, and this only
seems to happen on my Galaxy Tab 10.1 with Honeycomb, on other targets this
function does not use so much cycles.

So it should be a honeycomb problem, this specific example.

Thanks,
Rangel
