Try getting the phone memory filed up. So it starts GC'ing and killing off processes to release the memory. Or try filling up the heap with total garbage and trigger a GC. If after that point you actually have the unused(or what you would expect to become garbage) Activities and Views retained, then you have a leak.
High mem usage does not mean that there is a leak, by itself. And to have a low mem usage, you need to carefully create new objects and hold on to them for a long time. That goes also for Strings, resources and goes double for Bitmaps.
