@sujith The video is very good. To summarize,

  1. the video talked about a very difficult-to-find leaking by "non-static inner class". There is a detailed explanation about this in this page.
  2. He talked about some important concepts when using Memory Analyzer Tool such as shallow heap vs. retained heap, GC Root and dominator tree.
  3. He showed an example of using MAT to identify a leak. In MAT the most useful tool said by him are Histogram and Dominator Tree. When examining an object further, he used right-click menu "Path to GC Root" and then "Exclude Weak References".

I found this video very useful. This talks about things like how to find memory leaks from logcat(garbage collector logs) and how to use memory analyzer(MAT).

The dump.hprof file from Android needs to be converted. Then you can open the converted-dump.hprof in MAT.

hprof-conv dump.hprof converted-dump.hprof
