原因

  • 以下にあるように、libc++_shared.so なる共有ライブラリの重複

* What went wrong:
Execution failed for task ':launcher:mergeReleaseNativeLibs'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
> More than one file was found with OS independent path 'lib/armeabi-v7a/libc++_shared.so'. If you are using jniLibs and CMake IMPORTED targets, see https://developer.android.com/studio/preview/features#automatic_packaging_of_prebuilt_dependencies_used_by_cmake

対処法

  • UnityEditor の Custom Main Gradle Template にチェックを入れる
  • Assets\Plugins\Android\mainTemplate.gradle の defaultConfig に以下の packagingOptions を追加
android {
    defaultConfig {
        packagingOptions {
            exclude '**/libc++_shared.so'
        }
    }
}

備考

  • More than one file was found with OS independent path 'lib/armeabi-v7a/libc++_shared.so'. というメッセージなので、libc++_shared.so の重複と推測
  • 結局、エラーの1つ目の「WARNING: The option setting 'android.enableR8=false' is deprecated.」や2つ目の「-Xlint:deprecationオプションを指定して再コンパイルしてください」などは、libc++_shared.so重複問題の枝葉として無視するのが正解ですが、まあハマりますよね・・・。
