Bash script to find out how many methods your .apk file will contain. (Original idea from @rochoa)

dex-methods.sh

#! /bin/bash
if [ $# -ne 1 ]; then
	echo 
	echo " Usage: dex-methods.sh [dex file to explore] "
	echo
	echo
else
	NUMBER=`cat $@ | head -c 92 | tail -c 4 | hexdump -e '1/4 "%d\n"'`
	echo "The number of methods found is: " $NUMBER
