Android build fails with R8
10,430
Solution 1
I was facing this same problem. I simply updated the gradle version from 3.4.0 to the latest 3.4.2 and it worked.
Solution 2
I just had the same issue and I fixed it by specifying a special release version
in your project's build.gradle
repositories {
google()
jcenter()
repositories {
maven {
url "http://storage.googleapis.com/r8-releases/raw/master"
}
}
}
dependencies {
classpath 'com.android.tools:r8:1.6.84' // Must be before the Gradle Plugin for Android.
classpath 'com.android.tools.build:gradle:3.6.3'
}

Build is failing with the following error upon enabling R8 on android studio 3.4-RC3. Build is successful if
android.enableR8=falseUndefined value encountered during compilation. This is typically caused by invalid dex input that uses a register that is not define on all control-flow paths leading to the use.
What is this undefined value and how do I fix this error?
