Calling procrank doesn't work on real devices

Question

according to a google io video about getting to know how much memory you app takes , you can use procrank and read the USS value of it.

i've tried it out on emulators (no matter which version i use - from 2.3.x to 4.1) and it works well , but running on an actual device , it didn't work (tested on galaxy s3 with android 4.0.4) . it's as if the command doesn't exist .

how could it be ? is there an alternative to get this USS value?

Answer 1

You can use dumpsys command

Steps:

1. issue command line: dumpsys meminfo packageName
2. The Private Dirty column is you wanted.

Answer 2

U can also use

adb shell dumpsys meminfo

or

adb shell dumpsys meminfo  + pid

command

Answer 3

adb shell dumpsys meminfo [pid] (Private Dirty + Private Clean)

is same as

procrank (USS)
