Thanks for the report.

Could you please try to build with R8 version 13ef6fc45ca2604862d8a9a86c0afc93bc0bab16? This should cause the build to fail with a compilation error that could be useful for further diagnosis (https://r8-review.googlesource.com/c/r8/+/52672).

You can build with this version by making the following changes to build.gradle:

buildscript {
    repositories {
        maven {
            url "https://storage.googleapis.com/r8-releases/raw/master"
        }
    }
    dependencies {
        classpath 'com.android.tools:r8:13ef6fc45ca2604862d8a9a86c0afc93bc0bab16'  // Must be before the Gradle Plugin for Android.
        classpath 'com.android.tools.build:gradle:X.Y.Z'     // Your current AGP version.
     }
}

Would it be possible for you to share an Android Studio project where this reproduces? If you prefer to share it privately you can send it to christofferqa@google.com or sgjesse@google.com.

Alternatively you can also generate a dump containing the JVM class files that are input to R8 by running ./gradlew assembleX -Dcom.android.tools.r8.dumpinputtofile=/path/to/write/dump.zip .

Looks like some thing related to exoplayer .

Unfortunately I cannot share the project even privately as its not mine but clients .

gradlew assembleX didn't work for me , I have ran the command with gradlew assemble . This is the dump I got

https://drive.google.com/file/d/1kXA3n7fCngKa7_DCRhqYkgmpYUu2E0Zo/view?usp=sharing . I have added acces to above provided emails .

ch...@google.com <ch...@google.com> #5Aug 6, 2020 02:20PM

Thanks for the update! Which version of exoplayer are you using?

Unfortunately the shared dump seems to be malformed. Could you please try again with:

./gradlew assembleRelease -Dcom.android.tools.r8.dumpinputtodirectory=/path/to/directory

I will check if I can reproduce the issue locally based on the information from the CompilationError above.

an...@gmail.com <an...@gmail.com> #6Aug 6, 2020 06:06PM

Exoplayer dependencies I use

implementation 'com.google.android.exoplayer:exoplayer-core:2.10.8'
implementation 'com.google.android.exoplayer:exoplayer-hls:2.10.8'
implementation 'com.google.android.exoplayer:exoplayer-ui:2.10.8'

I have uploaded dump here

https://drive.google.com/drive/folders/15OCxyFhuzcxLScjAUzBwNbuc7x-iMOr1?usp=sharing and added access to above 2 emails . The dump created 5 files in total .

when I ran the gradlew assembleRelease -Dcom.android.tools.r8.dumpinputtodirectory=/path/to/directory I got the following error

Marked as fixed.

Thanks again for reporting this and taking the time to help us reproduce this problem!

The fix is in R8 version 2.1.61, and will be included in AGP 4.1.0. You can build with this version by making the following changes to build.gradle:

buildscript {
    repositories {
        maven {
            url 'https://storage.googleapis.com/r8-releases/raw'
        }
    }
    dependencies {
        classpath 'com.android.tools:r8:2.1.61'          // Must be before the Gradle Plugin for Android.
        classpath 'com.android.tools.build:gradle:X.Y.Z' // Your current AGP version.
     }
}

Please don't hesitate to let us know if you run into any other R8 related issues!
