我目前遇到了这个问题:Google map 似乎根本无法加载。请看下图:
这真的让我发疯。我已经完成了以下操作:
- 将我的包名称 + SHA1(调试 keystore )+ SHA1(发布 keystore )添加到 Google 开发者控制台。
- Android 版 map SDK 已启用。 API key 有 Android 应用限制
- 从 Firebase 控制台将 google-services.json 添加到我的应用
- 添加了必要的权限:
- 将 API key 添加到 list 文件 - 来自 Google Developer Console
- 为 gms 版本添加了元数据
这是我的 fragment 的代码:

谁能告诉我还缺少什么？

请注意，当我将相同的 API_KEY 用于其他 map 项目时，它工作正常。 map 似乎没有显示在我的应用程序上，而是在其他项目上显示。

最佳答案
昨天在公司做客户设计的时候遇到了这个问题。与我身后的客户一起解决这两个疯狂的日子。我所做的是:
从 Google 信息中心 API 中删除当前 key (API key )。 从 Google 仪表板 API 中删除 firebase 网络 key 。创建一个 新的 Android key API，注册 SHA-1 和包名称。和 在项目android studio中添加；
在 FIrebase 项目中删除 SHA-1 代码以重新添加。下载 google-services.json，在项目中添加；
在 Release模式下生成应用程序，在商店中发布，然后下载 在某些设备上，运行应用程序时应正常显示 map ；
如果不是，它会在 LogCat 中显示错误，说你必须 注册以下 SHA-1 key :XXXXXXXXXXXXXXXXX 和包 名称:com.your.package-name;
只需在 Google API 中注册该 key ，它就会在几个 秒，甚至无需更新商店中的应用程序。
注意:另一件事，考虑升级 Google map 和 Google 服务的依赖项。
希望这对您有所帮助。
