android - 在产品 flavor 中添加多个 google-service.json 文件

Question

我有 3 个不同的 Firebase 项目。并且必须在 4 中使用谷歌服务.json 用于产品香精。但我收到以下错误

File google-services.json is missing. The Google Services Plugin cannot function without it.

对于以下结构



如果我把 谷歌服务.json 在应用程序文件夹中，然后我收到此错误

No matching client found for package name 'com.example.app1'

对于以下结构



build.gradle

 flavorDimensions "category", "app"

    productFlavors {
        mcq1 {
            applicationIdSuffix ""
            dimension "category"
        }
        mcq2 {
            applicationIdSuffix ""
            dimension "category"
        }
        mcqappgj {
            dimension "app"
            applicationId "com.example.app1"
            versionCode 9
            versionName "1.0.7"
        }
        mcqappen {
            dimension "app"
            applicationId "com.example.app2"
            versionCode 7
            versionName "1.0.6"
        }
        gpscapp {
            dimension "app"
            applicationId "com.example.app3"
            versionCode 2
            versionName "1.0.1"
        }
        eemcq {
            dimension "app"
            applicationId "com.example.app4"
            versionCode 2
            versionName "1.0.1"
        }
    }

解决方案:

我能够做到这一点的唯一方法是绕过使用 google-services.json并创建 FirebaseApp动态实例例如

 if (<is dev>) {
        apiKey = <dev api key>;
        databaseUrl = <dev database url>;
    } else if (<is test> {
        apiKey = <>;
        databaseUrl = <>;
    } else // production {
        apiKey = <>;
        databaseUrl = <>;
    }


    FirebaseOptions firebaseOptions = new FirebaseOptions.Builder()
            .setApiKey(apiKey)
            .setApplicationId(context.getString(R.string.google_app_id))
            .setDatabaseUrl(databaseUrl)
            .build();

    return FirebaseApp.initializeApp(context, firebaseOptions, "MyApp");
