Libgdx enable proguard

I have been wanting to enable proguard for a long time now, but it seems to much of a hassle.

But I was thinking if is posible to only enable proguard to remove classes that the program don't uses, I have a simple game weighting almost 25mb and I don't even have 2mb of assets, I don't care about obfuscation.

This should be easier to implement right? since most errors when enabling proguard are because of obfuscation?

Can I do this? how?

Thanks

EDIT:

I use eclipse

build.gradle file:

buildscript {
    repositories {
        mavenLocal()
        mavenCentral()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
    }
}

allprojects {
    apply plugin: "eclipse"
    apply plugin: "idea"

    version = '1.0'
    ext {
        appName = "test"
        gdxVersion = '1.9.5'
        roboVMVersion = '2.3.0'
        box2DLightsVersion = '1.4'
        ashleyVersion = '1.7.0'
        aiVersion = '1.8.0'

        admobVersion = '10.2.1';
    }

Solution

  • Add this inside android app module. App module having pre build proguard-project.txt file having proguard rules that apply on your libgdx projects.

    buildTypes {
        release {
            minifyEnabled true   
            proguardFile getDefaultProguardFile('proguard-android-optimize.txt')
            proguardFile 'proguard-project.txt'
        }
    }

    Uncommit this line inside project.properties file.

    proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

    Hopefully you're not using skin, some time skin creates problem because object fetched from .json.
