Exoplayer won't compile on Android

Current behavior

My app doesn’t compile.

Reproduction steps

• Add and setup react-native-video
• Update the dependency on settings.gradle to ../node_modules/react-native-video/android-exoplayer

Expected behavior

The app would compile

Platform

• Android ExoPlayer

Errors

When running react-native run-android

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformClassesWithMultidexlistForDebug'.
> com.android.build.api.transform.TransformException: Error while generating the main dex list.

When trying to compile on Android Studio

Program type already present: com.google.android.exoplayer2.source.smoothstreaming.DefaultSsChunkSource
Message{kind=ERROR, text=Program type already present: com.google.android.exoplayer2.source.smoothstreaming.DefaultSsChunkSource, sources=[Unknown source file], tool name=Optional.of(D8)}

---

It seems like a conflict with my dependencies, but how can I find and address it? Searching through the web I couldn’t find any decisive answer.

package.json

"react-native": "0.55.4",
"react-native-video": "2.3.1",

Fixed for me by adding

    compileOptions {
        sourceCompatibility 1.8
        targetCompatibility 1.8
    }

in the android argument of the build.gradle

Have the same problem. Is there another solution for it?
