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.
