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."

proguard-rules.pro

-dontshrink
-dontobfuscate
-dontoptimize

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? – nibz 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

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
