`classes.dex` method count helpers. Requires smali/baksmali from https://code.google.com/p/smali/ and dexdump from the build-tools in the Android SDK be on your PATH.
function dex-method-count() {
cat $1 | head -c 92 | tail -c 4 | hexdump -e '1/4 "%d\n"'
}
function dex-method-count-by-package() {
dir=$(mktemp -d -t dex)
baksmali $1 -o $dir
for pkg in `find $dir/* -type d`; do
smali $pkg -o $pkg/classes.dex
count=$(dex-method-count $pkg/classes.dex)
name=$(echo ${pkg:(${#dir} + 1)} | tr '/' '.')
echo -e "$count\t$name"
done
rm -rf $dir
}

this sh file is used to count how many method in the dex file or split dex file to more than one dex file ?

Before I roll my own, do you use any kind of script to always point to the latest build tools directory in your PATH?

Hi, I'm a new developer.
How do I use this? I already have baksmali results, but when i call sh dex.sh, here is the error: dex.sh: line 3: `dex-method-count': not a valid identifier
Thanks

@sschuberth

@aried3r A version that always uses the latest build tools (and optional CSV output for use with the Jenkins Plot plugin) is here.

If someone is looking for the windows solution (like I was), I wrote a simple batch file here: https://gist.github.com/mrsasha/9f24e129ced1b1db791b

Don't use cat to feed a single file's content to a filter. cat is a utility used to concatenate the contents of several files together.

This would be better:

head -c 92 $1 | tail -c 4 | hexdump -e '1/4 "%d\n"'

:P


If you just want the dex count for one apk (not by package) you could do:

apk=/path/to/the.apk
unzip -p $apk classes.dex | head -c 92 | tail -c 4 | hexdump -e '1/4 "%d\n"'

function dex-method-count-by-package() {
dexdump -f classes.dex | grep \(in | awk '{print $4}'|awk -F/ '{print $1"."$2"."$3;}' | sort | uniq -c | sort
}

It's not very accurate but it's fast and simple :)

dex-method-count seems to return incorrect number of methods for me. I used the following script to count the number of methods in my jar file:

dex_dir=$(mktemp -d -t dex)
dex_file="$dex_dir/dexed.jar"
dx --dex --output $dex_file $1
baksmali $dex_file -o $dex_dir
count=$(find $dex_dir -type f -exec grep "\.method" '{}' \; | wc -l | tr -d ' ')
echo "There are $count methods in $1"
