Google Maps显示的是空白地图

Question

这真的快把我逼疯了。我已经做了以下工作：

1. 将我的包名+SHA1（调试密钥库）+SHA1（发布密钥库）添加到Google Developer的控制台。
2. 已启用用于Android的地图SDK。API密钥有Android应用程序限制
3. 从Firebase控制台将google-services.json添加到我的应用程序
4. 添加了必要的权限:
5. 将API键添加到清单文件-从Google Developer Console
6. 添加了gms版本的元数据

这是我的片段的代码：

我昨天在公司设计一个客户时遇到了这个问题。和我身后的顾客一起解决这件事真是疯狂的两天。我所做的是：

>

从Google仪表板API中删除当前键（API键）。从Google仪表板API中删除firebase web键。为android创建一个新的密钥API，注册SHA-1和包名。并添加project android Studio；

在FIrebase项目中，删除SHA-1代码，以便再次添加。下载google-services.json，并添加到项目中；
