我按照指南创建了一个谷歌地图样本,
但它总是抛出以下错误.
E/Google Maps Android API(27821): Failed to load map. Could not contact Google servers.

权限READ_GSERVICES以及调试和发布密钥库已经过测试.他们也无法解决上述问题.谁能告诉我为什么会抛出这个错误?

确保所有下面提到的要点都得到照顾:
1)启用了错误的服务.确保已启用" Google Maps Android API v2 ",而非" Google Maps API v2 "并重新生成API密钥.
2)将以下元素添加到清单中.将com.example.mapdemo替换为应用程序的包名称.
3)使用正确的证书和密钥.发布证书,当您在我的手机上运行应用程序时,调试期间无法正常工作.您必须使用调试密钥库证书指纹.
您添加了所有其他需要的权限吗?

更新:
1.
该meta-data部分应该位于应用程序标签的最下部,如下所示:

2.我看到的另一个问题是您为 API V8 开发应用程序,因此您必须将SupportMapFragment和用作FragmentActivity您的Activity.
3.要使您的地图正常工作,您必须添加 Google 许可信息的许可活动。
