Android View Memory usage

Look at the development process, often to use the amount of memory to optimize the program.

To view the application's commands: adb shell Procrank

Note: VSS -Virtual Set Size virtualized memory consumption (contains memory consumed by shared libraries) 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)

To view the amount of memory consumed by a single application: adb shell dumpsys meminfo $包名 或者 $ process Number//Of course you can also enter the remainder of the ADB shell after entering.
