DDMS and os show different memory info about my app

Question

I'm working with the ddms to find memory leaks and other bugs. When tracking the memory I see a heap size of 30MB.

But when I go to device and check the memory in the application manager I see 70 MB.

Is it normal? What's the reason for this ?

Device : SamsunGalaxy GT9300

Answer 1

Yes its normal, DDMS shows only running app memory. You can also try another tool like memory analyser tool(MAT). You see best result comparison to DDMS.
