How to determine application's method count?

I'm encountering issues with my application having too many methods.

In the last post in the below link, a poster posts the method count for his application (broken down by package). I unable to find how I can get this information for my application, any suggestions?

If you have already built application, then you can use dexdump (AOSP tool) for this:

# Get the number of classes.
dexdump -h ApkName.apk | grep "^class_idx" | wc -l
# Get the number of methods.
dexdump -h ApkName.apk | grep "method_idx" | wc -l

To get a method-count report on every build, do this:

in app/build.gradle:

buildscript {
    repositories {
        mavenCentral() // or jcenter()
    }

    dependencies {
        classpath 'com.getkeepsafe.dexcount:dexcount-gradle-plugin:0.7.3'
    }
}

// make sure this line comes *after* you apply the Android plugin
apply plugin: 'com.getkeepsafe.dexcount'

It will show the number of methods per package, for your own project and the libraries you use.

To find and Android app method count with or without multidex support use: 

find | grep classes.dex | xargs -I {} hexdump -e '"%d {}\n"' -s 0x58 -n 4 {}

You can use APK Analyzer in the Android studio

There is a tool APK method count which counts the number of methods in your apk.

There is also a service methodscount.com to check method count of libraries. This service also has Android Studio/IntelliJ plugin that parses your Android library dependencies and shows the methods count as an handy hint.

I use

cat build/dex/debug/classes.dex | head -c 92 | tail -c 4 | hexdump -e '1/4 "%d\n"'

I get 55176. 64k limit is coming :D

You could use JavaNCSS to get such statistics. It is available here: http://www.kclee.de/clemens/java/javancss/

Try to use a static code analyzer; Source Monitor, for example, is free SW and has the count you're searching for.

Or if you prefer to do it without additional plugins, try doing this (Eclipse only):

  • Press Ctrl-H (Search), then select the "Java Search" tab (if it doesn't appear click on the "Customize..." button at the lower left corner)
  • Put * in the search box
  • Select "Method" in the "Search For" fieldset
  • Select "Declarations" in the "Limit To" fieldset
  • Select "Sources" in the "Search In" fieldset
  • Select "Workspace" in the "Scope" fieldset
  • Click on "Search"

After the search is complete you should see a "XXXX declarations in..." message in the search view and that will be your result.

Hope it helps!
