Android Memory Total / Guidelines ?
If I am aiming at Android devices with 512mb+, what is a reasonable memory budget to go for ? At the extreme, how much can you get away with before Android might jettison the app ?
Given that I have this target, how do I know if I am actually meeting it ? I have data from various sources that doesn't match up well, does anyone know which is the most accurate total ? (see below for the different attempts, which is the best/combination for a 'total' ?) :
Using 'adb shell dumpsys meminfo' (132mb)
133832 kB: Foreground 133832 kB: [process_name] (pid 26451)
Using 'adb shell dumpsys meminfo [process_name]' (135mb)

Same Level on iOS (170mb)
~170mb in the activity manager......
Confused...and grateful for any tips !
not just cpu but also gpu will vary wildly on android, your best bet is to test on a wide variety of devices and get firsthand experience... the profiler is useful for identifying bottlenecks...
Ok, I'm getting similar results from the (much improved) 4.1 memory profiler at ~133mb total.
Why is iOS so much more...I'll take a look once it re-imports.
