我在我的genimotion中使用它并且它显示正常，但在我的真实设备中它只是在屏幕:(，我配置我的代码很长时间但它仍然没有显示。
API_Key是对的，几乎是正确的，我想是因为我在genymotion中正常破坏。
这是我的代码：

解决：感谢## Arun Antoney ##，只导出签名的APK然后在显示的最后一步注册SHA-1，它运行得像一个chamed：3
答案 0 :(得分：0)
请尝试这种方式，希望这有助于您解决问题。
https://developers.google.com/maps/documentation/android/start
1.我认为问题在于获取API密钥或使用SHA-1指纹。
2.您是否在Google Consol
中为应用程序包提供了SHA-1指纹3.将Google Play服务安装到您的模拟器或Android设备中。
4.请使用Android设备进行地图测试或Genymotion模拟器。
答案 1 :(得分：-1)
使用项目密钥库文件和软件包名称创建新的api密钥。然后尝试，因为使用 debug.keystore 创建的api将仅在调试模式下显示地图
