How to turn off only the obfuscation in Android R8?

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."

TLDL

proguard-rules.pro

-dontshrink
-dontobfuscate
-dontoptimize
Solution

  • 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.
