Android web UI Performance is dramatically slower than iOS (why?) -


i wanted test android html5/javascript web app, purchased nexus 7 (2nd gen), , upgraded os lastest 4.3.

the nexus has substantially better specifications old test ipad 2:

  • 2gb ram vs 512mb
  • 1.5ghz x 4cores vs 1ghz x 2cores

however i'm finding nexus ui interaction on web pages between ~5-10 times slower ipad. button presses, animations , very laggy. example button press flipping pressed unpressed on ipad 2 keeps pace fast finger can twitch, when drumming 2 fingers, (greater 5/sec). whereas nexus noticeably lagging behind user touch @ less 1/sec. in fact android/nexus slow misses un-touch event, leaving button in depressed state.

i trying the bottom of this, limitation in os? problem hardware? (this googles own device though) java jvm overhead limiting performance? (though i'd think chrome native c/c++). there fix?

i ran browser javascript test (dromaeo), , computational results you'd expect (the newer fast nexus around 2x speed of old ipad). though did notice oddly ipad out-performed nexus in dom manipulation tests around 2x, though still not dramatic in user experience.

any thoughts?

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
