Eclipse has a powerful memory analyzer tool: MAT.
Does Android Studio have such a powerful tool, too ?
p.s. I have found a "Allocation Tracking" in the Android DDMS page. And I also know the "Memory Monitor".
But they seem very simple. Take "Memory Monitor" for example, it is only a wave graph. I don't even know which object are still connecting with the GC root.
With 1.3, they have integrated heap viewer in studio.
