Re: [android-developers] Dumpsys meminfo explanation...

How is the number of "Local Binders" counted?

For other types of memory usage (e.g., graphics), how can we collect usage info and how can we tell whether the app is using way too much of a particular type of memory (i.e., allocating too many instances of certains types)?

It is...   everything else.  By its nature, it doesn't tell you much, because it is all the other stuff that is not classified.  This may be:

- Graphics driver allocations.

- Window surfaces

- Cursors

- Audio buffers

- Binder transaction buffers

- Large malloc heap allocations (on some versions of the platform this can not be identified as part of the heap)

- Pages in ram (either clean or dirty) from mmapped files like shared libraries, dalvik code, .apks, etc.

Hi Kostya,

Thanks for the information...It explained the terms native and dalvik but i am still not clear about other (every thing else) memory. What is this other memory exactly (22082 is very high)?. Also could please elaborate more on the following numbers and their impact on memory.

 

 SQL
            heap:      168       memoryUsed:      168
pageCacheOverflo:       35  largestMemAlloc:       50

 DATABASES
  Pagesize   Dbsize  Lookaside  Dbname
      1024       29         72  settings.db
      1024       16         33  accounts.db

Thanks
