How to turn off only the obfuscation in Android R8?

Question

I use Android Studio 3.3 Canary 5, Gradle 4.9, gradle plugin 3.3.0-alpha05

minifyEnabled true
useProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

Does't work.

Edit:

@JakeWharton: "You use ProGuard configurations for this, not a Gradle DSL. Disable shrinking with -dontshrink, disable obfuscation with -dontobfuscate, and disable optimization with -dontoptimize."

-dontshrink
-dontobfuscate
-dontoptimize

Following this answer, I was able to solve this issue. Instead of editing the build.gradle file, I added -dontobfuscate to the proguard-rules.pro file. (You can configure a different proguard rules file for debug and release builds.) This skipped the obfuscation step and allowed me to make shrink'd debug builds with R8.

We shouldn't use **gradle.properties** for this? – IgorGanapolsky Sep 24 '20 at 14:18

In your gradle.properties file, add this line

 android.enableR8=false

This worked for me.

useProguard will soon be deprecated, any idea how we could fix this issue ? https://stackoverflow.com/questions/57736108/proguard-problem-after-updating-to-android-gradle-plugin-3-5 without disabling R8? – user2234 Jan 30 '20 at 01:44
This isn't deprecated? – IgorGanapolsky Sep 24 '20 at 14:25

This turns off R8 completely, both obfuscation and shrinking. – LukaCiko Oct 06 '20 at 07:49

This is now removed in Android Gradle Plugin 7.0 – Vikas Patidar Aug 17 '21 at 13:02

build.gradle

buildTypes {
    release {
        shrinkResources false
        minifyEnabled true // R8 or ProGuard will be enabled.
        proguardFiles 'proguard-rules.pro'
    }
    debug {
        shrinkResources false
        minifyEnabled false // R8 or ProGuard will be disabled.
    }
}

This answer does not demonstrate how to disable obfuscation within R8. It instead shows how to disable obfuscation at the build level.

I found setting minifyEnabled to false in build.gradle disables R8 and thus removes obfuscation. Obligatory reminder: Be cautious disabling obfuscation as it will mean the source will not be cloaked whatsoever.

This not answer the question "How to turn off *only* the obfuscation in Android R8?" Seems to me an AI nonsense comment – norbDEV Jul 25 '23 at 12:04
@norbDEV This isn't an AI generated answer. I came across this question when trying to figure out how to disable obfuscation. However, I understand that my answer isn't directly related to the question so I'll edit it to reflect that. – tyirvine Jul 25 '23 at 16:15
