Hi, It's pretty easy. Launch the tool called DDMS (the standalone one, not the one that comes with the Eclipse plugin.) Inside the tool, go to the Allocations Tracker tab. Click Start Tracking, use your app a little, then click Get Allocations. You will get a list of all allocations with, for each one of them, the stack trace to the allocation.
