android - 默认Unity gradle中的多个Dex文件

Question

达到 64k 方法限制后，我尝试将我的 Unity 项目导出为 gradle 构建。导入Android Studio后报错

Error: A library uses the same package as this project: com.myproject.name

找到这个之后question我加了

enforceUniquePackageName = false

我的 gradle 项目。现在我可以在 Android Studio 中运行该项目，但正如该问题的答案中所述，当我尝试构建 APK 时出现以下错误

Multiple dex files define Lcom/myproject/myappname/BuildConfig;

我的gradle文件如下

// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN
buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
    }
}

allprojects {
   repositories {
      flatDir {
        dirs 'libs'
      }
   }
}

apply plugin: 'com.android.application'

    enforceUniquePackageName = false

    defaultConfig {

    lintOptions {
        abortOnError false
        disable 'MissingTranslation'

    signingConfigs { 
      //omitted!
    }

    buildTypes {
        debug {
            jniDebuggable true
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-unity.txt'
            signingConfig signingConfigs.release
        }
    }

}

删除不同的插件并尝试构建后，如果我注释掉最后一个插件unity-android-resources，似乎我可以构建项目，但当然我的应用程序无法正常运行。为什么会出现这个错误，我该如何解决这个问题？

Answer 1

您的最后一个项目 unity-android-resources 在 AndroidManifest.xml 中与基础应用程序具有相同的 packageName(在 gradle 参数 applicationId 中)。您可以编写任何其他 packageName，例如 com.example.myapplication.resources。
