Android cpu cores reported in /proc/stat

Question

I am developing an Android application that shows the CPU load per core and memory consumption. For CPU load I am reading /proc/stat and for memory -> /proc/meminfo. However

Answer 1

I have been searching about how to get CPU usage from android for days and nights and I run into that problem some times.

Well, if I am not wrong I think that when you don't get a CPU core means that the core that is not been displayed is offline (android do so to prevent huge battery drain).

If you want to find out how many core the android has find another way, there are tooooons out there, and then do whatever you like.
