Answer 1

I wrote a script based on @JesusFreke's answer for this problem and for another problem (https://stackoverflow.com/a/21485222/6643139):

#!/bin/bash
unzip $1 classes.jar -d aarsize &&
  dx --dex --output=aarsize/temp.dex aarsize/classes.jar &&
  hexdump -s 88 -n 4 -e '1/4 "%d\n"' aarsize/temp.dex &&
  rm -rf aarsize

Save it to a file name "aarsize", chmod +x for it, output of aarsize your_aar_file :

$ aarsize status-bar-compat-release.aar 
Archive:  status-bar-compat-release.aar
  inflating: aarsize/classes.jar     
91

The 91 is the method counts of your aar file.
