Hi,
Suppose I have an executable of size 60MB and I want to execute it on android(ARM), will 60MB be allocated to load the code onto the RAM?
I remember studying about demand paging in Linux kernel. Is it relevant here? If yes, is it implemented in Linux kernels used in Android?
All executables are brought into memory through demand paging. So the kernel will only load those parts of the executable that are actually executed.
Swap isn't typically enabled by default though (I don't recall the exact config options).
