我一打开它就崩溃了。这是我的工作空间文件，

aar_import_external(
      name = 'com_google_firebase_firebase_messaging_directboot_17_0_3',
      licenses = ['notice'], # apache
      aar_urls = ['https://dl.google.com/dl/android/maven2/com/google/firebase/firebase-messaging-directboot/17.0.3/firebase-messaging-directboot-17.0.3.aar'],
      aar_sha256 = '',
      deps = [
        '@com_google_android_gms_play_services_basement_16_0_1//aar',
        '@com_google_android_gms_play_services_tasks_16_0_1//aar',
        '@com_google_firebase_firebase_common_16_0_3//aar',
        '@com_google_firebase_firebase_iid_17_0_4//aar',
        '@com_google_firebase_firebase_messaging_17_3_4//aar',
        '@com_google_android_gms_play_services_stats_16_0_1//aar',
        '@com_google_firebase_firebase_iid_interop_16_0_1//aar',
      ],
    )

我在 BUILD 文件中导入相同的内容。

关键是使用 bazelbuild/tools_android 中的工具集成 google-services.json 。 Android 构建需要对生成为资源 XML 的 JSON 文件进行后处理。
