您没有API密钥来访问Google地图。首先，您需要从谷歌开发者网站获取API密钥并将其保存在您的字符串资源文件中，并在您的清单文件中分配密钥。然后，只有您可以访问谷歌地图。

Caused by: java.lang.RuntimeException: API key not found.  Check that <meta-data android:name="com.google.android.geo.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml

@ prashant-gupta的回答也是有效的。但您可能正在使用较新版本的Android版地图。如果您查看Getting Started页面，则第4步表示您创建了Android Studio已创建的google_maps_api.xml。在开发人员控制台中创建API密钥后，将其复制到xml，它应该可以正常工作。
