Detect Android Memory Leaks

view story

http://stackoverflow.com – When i debug my app process in DDMS (with Update Heap selected) on every "Cause GC" all data in columns is stay same as I expect, also when I press Home Button and return to app all data also is same, but on every app restart (press Back button on phone and then re-open app again) data in "Allocated" columns little increase. For example: 14 335 MB, 14 353 MB, 14 370 MB, 14 383 MB. Is that mean my app has memory leaks ? (HowTos)
