keepsafe / android-resource-remover

A simple utility to remove unused resources in your Android app to lower the size of the APK. It's based on the Android lint tool output.

android-resource-remover

android-resource-remover is utility that removes unused resources reported by Android Lint from your project. The goal is to reduce your APK size and keep the app clean from unused stuff.

Getting started

Requirements:

• Python >= 2.7.*
• ADT >= 16

To install run:

pip install android-resource-remover

Usage - general

Open the directory where your app is located and run

android-resource-remover

Android resources have dependencies to each other. This means that after running resource-remover the first time, it will clean up unused resources file that hold a reference to other resources. You can run this resource remover multiple times until there is no more unused resources to be removed. We've been running it up to 4 times in a row.

Use with gradle

android-resource-remover is build on top of android lint. If you have a gradle project you have to run lint within your gradle build scripts and then use the lint-result.xml as the input file for android-resource-remover

e.g.

./gradlew clean build :lint && android-resource-remover --xml build/outputs/lint-results.xml

Options

--help

Prints help message.

--lint

Full path to the lint tool like: d:\Dev\Android SDK\tools\lint

This will be executed as the lint command. If not provided it assumes the lint command in available and runs: lint

--app

Full path to the android app like: d:\Dev\My_Android_App

If not provided it assumes the current directory is the app's root directory.

--xml

Use existing lint result. If provided lint won't be run.

--ignore-layouts

Ignore layout directory

Expected behavior

Resource ID in code not found

If you have references to elements in an old layout that you're not using anymore, you will get a compile error that the ID (R.id.<something>) can not be found. The reason is that the resource file that contained R.id.<something> has been removed as it was not used any more. Time to clean up your code.

Does this tool support latest gradle android project structure?

Hi guys, thanks for such cool tool.
When I try to run it with lint XML file it fails. It says that manifest file can't be found.

Error: search AndroidManifest.xml in gradle project

For gradle project, AndroidManifest.xml file normally placed in app/src/main/AndroidManifest.xml but this library always find in app/AndroidManifest.xml then never see it.

IOError: Error reading file 'build/outputs/lint-results.xml'

Hi,
Unfortunately, I wasn't able to get it into for two days so decided to get some help.
For some reasons I'm not able to use your suggested command, ./gradlew clean build :lint && android-resource-remover --xml build/outputs/lint-results.xml.

• build tries to create a release and since I'm work on company project and its credential isn't in build.gradle file so process fails.
• Gradle :lint is not in root of your project.

So what I do is I first create a debug .apk in normal way. Second, I run lint from Gradle window, My-app/app/verification/lint. So lint-results.xml will be created in my build/output folder. I run this command in terminal now android-resource-remover --xml build/outputs/lint-results.xml. Then I get following error.

I'm using Android Studio 2.0 Preview 5 on Ubuntu 14.04 LTS. Any suggestion would be appreciated. Thanks.

It seems that new android studio version has removed lint in build script

Remove strings from other locals that are marked as translatable="false"

Android supports translatable="false" in the <string> tag. Strings that are marked as false should be removed from other locales. This will help for the case that they got translated by accident.

Compiling will give the following error when not.

/Users/philipp/coding/keepsafe/app/src/main/res/values-es/material-strings.xml:2 : warning: string 'transition_thumbnail' marked untranslatable but exists in locale 'es'

Note that these strings can lead to crashes if the string is looked up on any locale not providing a translation, so it&apos;s important to clean them up."

Problem removing unused dimens and strings

When using the latest version of your script, the console output correctly prints out the message

removing ('dimen', "<dimen_name>") from resource ./res/values/dimens.xml
removing ('string', "<string_name>") from resource ./res/values/strings.xml

for all dimens and strings files but doesn't actually remove the said unused resource from the file. Is this a known issue?

oh,no

It cleaned all my resources in drawable-*dpi,but kept the unused resource

  Task 'lint' not found in root project 'android-nag-client'. Some candidates are: 'init'.

It does not work with Android Studio Lint Result

I used Android Studio->Analyze->Inspect Code to get a lint result and export to xml named AndroidLintUnusedResources.xml. Then I used command 'python android-resource-remover --xml AndroidLintUnusedResources.xml' , but it does not work. Anything I did wrong?
AndroidLintUnusedResources.txt

integrate python code

Hello, I wonder that how did you integrate python code in your java code? Which plugin or component did you use for it?

Thanks in advance :)

Didn't work

Hii, quite simply, I stumbled upon your code through google, and my gradle build is failing due to missing resources. Just FYI, I'll let you know if I have more conclusive info. Need to update lint and get lint working properly as well, will let you know.

A problem with Gradle.

I am very sorry to trouble you. But when i used with Gradle, the unused pictures won't be deleted.
I have runned lint and lint-results.xml are in build/ouputs directory. the i run ./gradlew lint && android-resource-remover --xml build/outputs/lint-results.xml and it build successful.
But i find the unused pictures are still in.

Is any where i used wrong? Please help me find it.Thank you very much.

Need clarification

@ca77y So i ran your tool with lint results xml file and it gave me a bunch of output mentioning removing strings ...
all the output was mentioning removal of strings from libraries that are used inside the project, none of the actual unused resources from strings.xml and drawable folders were removed. I ran lint again in android studio and all the unused icons were still there

Installation issues with pip

easy_install seems to behave nicer with el-capitan than pip. i suggest to change the ReadMe accordingly.
