【问题描述】：

我将我正在开发的 unity 项目导入 Android Studio，以便摆脱 READ_PHONE_STATE 和 WRITE_EXTERNAL_STORAGE 权限，unity 2017.2 会自动恼人地添加到 APK 构建中。

在将 build.gradle 版本从 2.1.0 更改为 3.0.0 后，我成功地将项目导入 Android Studio 3.0。清理项目，现在我可以构建了。

问题是我无法构建。我遇到了错误：

Error:Error converting bytecode to dex:
Cause: com.android.dex.DexException: Multiple dex files define Lcom/google/games/bridge/BuildConfig;

和

Error:Execution failed for task ':transformDexArchiveWithDexMergerForDebug'.
> com.android.build.api.transform.TransformException: com.android.dex.DexException: Multiple dex files define Lcom/google/games/bridge/BuildConfig;

和

Error:Error converting bytecode to dex:
Cause: com.android.dex.DexException: Multiple dex files define Lcom/tappx/sdk/android/BuildConfig;

和

Error:Execution failed for task ':transformDexArchiveWithDexMergerForDebug'.
> com.android.build.api.transform.TransformException: com.android.dex.DexException: Multiple dex files define Lcom/tappx/sdk/android/BuildConfig;

我的统一项目添加了以下插件：

  • PlayGames for unity v 0.9.42
  • Firebase SDK（分析、动态链接、通知、remoteConfig）v 4.2.1
  • IronSource SDK
  • TappX SDK

请查看我的 build.gradle 文件

        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-unity.txt'
        signingConfig signingConfigs.release
    }
}

}

我尝试添加 multiDexEnabled = true - 但它对输出没有任何影响。

    【解决方案1】：

    （我是 Firebase C++ / Unity 团队的开发人员）

    听起来你达到了敏捷上限。在 Assets->Google Play Services->Android Settings->Settings 菜单选项中有一种使用“Gradle Prebuild”的实验方法。

    但是，这仍然是实验性的。如果它不起作用，当前建议的工作流程是将构建系统设置为 gradle，选择“导出”，将您的项目导出到 gradle，在生成的 gradle 构建中启用 proguard 剥离，然后从那里构建您的项目。

    【讨论】：

    • 非常感谢。尝试“Gradle Prebuild”并构建成功。
