Ok, the numbers from a Galaxy Nexus with 4.0.2: hw accel off: animated frames take 7-10-13 ms. hw accel on: animated frames take 2-3-4 ms.
The widget / app selector on my Galaxy Nexus does stutter somewhat, but if I scroll it all the way and then back again, it then animates much smoother. Based on this, I'd think it's the app / widget icon cache population, not the drawing. -- Kostya 16 января 2012 г. 22:53 пользователь Kostya Vasilyev <[email protected]> написал: > FWIW: > > One of my apps, WiFi Manager has a very simple graphical network view: > > https://lh4.ggpht.com/RAtqQLlAi6N-oiLg_B6HIKL3ltk0Flb7y52-GRIHz4F7s5Ob4lg8gRpCQ2z1fbSLmQ > > ( it's taken on a 2.* phone, but you get the idea ). > > I just added some profiling code and tried it on a Sony Tablet S, 10", > 1280*800, running 3.2.1, with android:hardwareAccelerated="false" and > ="true". > > While animating, each frame takes 0-1-2 ms with acceleration on, and > 7-10-13 ms with acceleration off. > > The view is drawn in a very straightforward way, just some lines and > ellipses text, using Canvas. > > I can post numbers for a Galaxy Nexus later if you're curious. > > -- Kostya > > 16 января 2012 г. 22:41 пользователь sblantipodi > <[email protected]> написал: >> Just to add some more data. >> This simple app can render its UI at 60FPS on Galaxy Nexus running >> stock 4.0.2 with HW ACC is OFF. >> https://market.android.com/details?id=MortgageCalculatorPRO.DPsoftware.org&feature=search_result#?t=W251bGwsMSwyLDEsIk1vcnRnYWdlQ2FsY3VsYXRvclBSTy5EUHNvZnR3YXJlLm9yZyJd >> >> Simply enable hardware acceleration and the framerate drops from 10FPS >> to 30FPS. >> As I repeat all the UI is drawn using drawLine() drawRect() >> drawRoundRect() and StaticLayout to draw a correctly wrapped text. >> Simple apps using simple UI runs slow on a 1.2GHz CPU with 1GB of RAM. >> >> Is there any reason to justify this aside from the fact that it must >> be some problem in the hw acceleration implementation? >> >> -- >> You received this message because you are subscribed to the Google >> Groups "Android Developers" group. >> To post to this group, send email to [email protected] >> To unsubscribe from this group, send email to >> [email protected] >> For more options, visit this group at >> http://groups.google.com/group/android-developers?hl=en -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
