I would like to know how much memory dalvik VM is allocated with (heap + stack) to run applications.
There is an option while creating an AVD to allocate RAM i.e. by default 96 MB and initial heap size i.e. by default 16 MB ..What is the significance of this? can anyone explain? Programatically if i want to calculate the system memory which i assume is the memory allocated to the dalvik VM then is there a way to do that ? Next, if i want to find the memory consumption at the application is there a way ? There is an adb command like 'adb dumpsys' which gives memory related information .Can i do something similar in code. Is there an API available ? I know i am asking a very vague question but thats how memory management is ! :) Thanks, Adithya.
