Android start a program, at least how much memory overhead?

My own test results is about 10 megabytes, do not know right?

With this view I do not know right?

 
System.gc (); 
Runtime rt = Runtime.getRuntime (); 
System.out.println ("Total Memory =" + rt.totalMemory () + ", has been used =" + (rt.totalMemory ()-rt.freeMemory ()) + ", available =" + rt.freeMemory () + "maximum =" + rt.maxMemory ()); 

I always suspect that their memory is not freed by the feeling when used memory when close to 10 trillion, said he basically recovered memory overhead, is not it so?

No new evidence seems to start an AP to 10 megabytes of memory.

In the system / build.prop configuration below a minimum heap.
dalvik.vm.heapstartsize = 8m
dalvik.vm.heapsize = 384m / / maximum over crash.

Not need to 10M, is assigned 10M. Did not add up enough to use the initial allocation instructions.
