AppCenter构建成功但无法找到APK文件（React Native）

在AppCenter中构建React Native Android项目时，Gradle任务执行完成后显示BUILD SUCCESSFUL，但后续的Android Postprocess环节未找到APK文件，Sign APK任务因匹配不到.apk文件报错。未在AppCenter中添加任何额外的预处理或后处理脚本，尝试多种方案仍未解决。

解决方法 #

• 确认Gradle构建任务：日志显示构建标签包含android-app-bundle，说明当前可能只生成了App Bundle（.aab）而非APK。需要在AppCenter的构建配置中，将Gradle任务指定为assembleRelease，确保同时生成APK文件。
• 检查APK输出路径：默认APK输出路径为android/app/build/outputs/apk/release/，如果项目自定义了输出目录，需调整Postprocess和Sign任务的搜索路径，确保能匹配到.apk文件。
• 验证build.gradle配置：查看项目android/app/build.gradle中buildTypes节点，确认是否开启了enableSeparateBuildPerCPUArchitecture导致APK分散到不同ABI子目录，或者是否配置了仅生成App Bundle。若开启多ABI构建，需确保Postprocess脚本能遍历所有子目录寻找APK。
• 开启详细Gradle日志：在AppCenter构建设置中开启详细日志模式，查看Gradle任务执行的完整输出，确认是否真的生成了APK文件，以及生成的具体路径。
• 清理构建缓存：在AppCenter构建前清理缓存，避免旧缓存导致文件生成异常，确保本次构建是完全重新生成的产物。
