Project description

[![Build Status](https://travis-ci.org/KeepSafe/android-resource-remover.svg?branch=master)](https://travis-ci.org/KeepSafe/android-resource-remover)

![resource-remover](https://keepsafe.github.io/i/proj/opensource_resource-remover.png) android-resource-remover ========================

android-resource-remover is utility that removes unused resources reported by [Android Lint](http://developer.android.com/tools/help/lint.html) 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:DevAndroid SDKtoolslint

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:DevMy_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.
