可行解决步骤 #

• 关闭APK对齐选项：在生成签名APK的向导页，取消勾选Zip对齐已生成的APK选项，完成打包后可手动使用SDK中build-tools目录下的zipalign工具执行对齐操作
• 升级Android Gradle插件：该报错是旧版Android Studio打包向导的已知缺陷，将项目根目录build.gradle文件中的com.android.tools.build:gradle依赖版本升级至7.0及以上，同步项目后重新尝试打包
• 清理构建缓存：依次执行Build → Clean Project、Build → Rebuild Project，删除项目根目录下的.gradle、.idea文件夹和app模块下的build文件夹，重启Android Studio后重试
• 改用命令行打包：跳过图形化向导，直接在项目根目录执行命令：
  • Mac/Linux系统：./gradlew assembleRelease
  • Windows系统：gradlew assembleRelease
