配置:audio_service模块时Gradle报错：未指定Namespace

错误详情 #

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':audio_service'.
> Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
   > Namespace not specified. Please specify a namespace in the module's build.gradle file like so:

     android {
         namespace 'com.example.namespace'
     }

     If the package attribute is specified in the source AndroidManifest.xml, it can be migrated automatically to the namespace value in the build.gradle file using the AGP Upgrade Assistant; please refer to https://developer.android.com/studio/build/agp-upgrade-assistant for more information.

BUILD FAILED in 2m 56s
Exception: Gradle task assembleDebug failed with exit code 1

修复步骤 #

• 定位正确的配置文件：确保修改的是:audio_service模块下的build.gradle（而非项目根目录的build.gradle）。
• 添加Namespace配置：在该模块build.gradle的android代码块内，补充namespace属性，值为模块对应的包名，示例：

  android {
      namespace 'com.yourpackage.audio_service'
      // 保留原有compileSdk、defaultConfig等配置
  }
  

  若模块的AndroidManifest.xml中有package属性，namespace的值必须与该package完全一致。
• 清理缓存后重构：执行命令清理Gradle缓存，避免旧配置残留：

  ./gradlew clean
  

  之后重新运行构建命令。
• 排查常见错误点：不要把namespace写在根目录配置文件中；检查包名拼写是否正确；AGP 7.0+版本强制要求namespace，不可省略。
