如何将两个或多个google-services.json文件集成到同一个项目中的不同Google FCM服务中

Question

我正在制作一个项目，我想在其中集成不同的FCM google-service.json，如何在同一个文件中集成不同的项目键，我尝试了2个项目，但不起作用，我们需要添加到我们的项目中。

目前尚不清楚您的用例是什么，但值得注意的是，使用google-services.json文件是完全可选的，在您的情况下，您可能希望跳过它并手动配置您的应用程序。

此处的文档介绍了插件如何处理 JSON 文件。

基本上，该插件创建了一个如下所示的strings.xml文件：

<?xml version="1.0" encoding="utf-8"?>
<resources>
<! -- Present in all applications -->
<string name="google_app_id" translatable="false">1:1035469437089:android:73a4fb8297b2cd4f</string>
<! -- Present in applications with the appropriate services configured -->
<string name="gcm_defaultSenderId" translatable="false">1035469437089</string>
<string name="default_web_client_id" translatable="false">337894902146-e4uksm38sne0bqrj6uvkbo4oiu4hvigl.apps.googleusercontent.com</string>
<string name="ga_trackingId" translatable="false">UA-65557217-3</string>
<string name="firebase_database_url" translatable="false">https://example-url.firebaseio.com</string>
<string name="google_api_key" translatable="false">AIzbSyCILMsOuUKwN3qhtxrPq7FFemDJUAXTyZ8</string>
<string name="google_crash_reporting_api_key" translatable="false">AIzbSyCILMsOuUKwN3qhtxrPq7FFemDJUAXTyZ8</string>
</resources>

既然你说的是FCM，那么相关的部分是google_app_id、gcm_defaultSenderId和google_api_key。 如果您在应用中使用这些名称创建字符串，Firebase 将自动正确初始化。

如果你想使用多个应用程序，正如你所说，你需要像这样手动初始化FirebaseApp：

FirebaseApp customApp = FirebaseApp.initializeApp(this, 
new FirebaseOptions.Builder()
.setApplicationId(...)
.setApiKey(...)
.setGcmSenderId(...)
.build(), 
"custom-app-name");
