Vsize is a virtual memory

RSS is physical memory.

Android Medium " PS "The tool provides only a display vsize and the RSS only. These numbers are not very useful to show the actual cost of a particular application or sprite in memory. Smem is the tool used to analyze memory usage. Specific reference:

Terms

• VSS -Virtual Set Size Dummy memory consumption (contains memory occupied by shared library)
• RSS -resident Set Size actually uses physical memory (contains memory consumed by shared libraries)
• PSS -Proportional Set Size actual physical memory used (proportional allocation of memory consumed by shared libraries)
• USS -Unique Set Size process consumes the physical memory alone (does not contain the memory occupied by the shared library)

In general, memory footprint has the following rules: VSS >= RSS >= PSS >= USS
