我最近将我的所有工具更新为sdk 23.当我使用活动向导创建Google Maps Activity时，它会成功创建，但是当我在设备上运行时，地图不会显示。我得到的只是左下角的谷歌徽标。
我尝试过的事情：
使用debug.keystore
中的SHA-1创建API密钥- 重新生成的API密钥和经过验证的软件包名称
- 确保我启用了Google地图v2 for Android＆＃39;而不是谷歌地图v2＆＃39;
- 看了一眼并尝试了我能找到的这个网站上的所有相关解决方案（+ - 10），其中没有一个有效
- 确保我将google-play-services作为项目依赖
- 确保Google Play服务与其他工具一起更新

我的想法很新鲜。

此问题通常与用于签署清单的Maps API Key有关。在Google API console中创建API密钥时，需要确保使用调试密钥库。
当您准备将应用推向市场时，请在AndroidManifest.xml中设置android:debuggable="false"并使用Signed API key。
使用已签名的API密钥时，只有从Android电子市场安装应用程序时，MapView才会显示。因此，MapView将显示出来。
如果您的应用中有多个软件包，请在创建API密钥时注意，必须使用android mainfest.xml文件顶部的软件包名称
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
*package="com.xxx.xxx"*
android:versionCode="1"
android:versionName="1.0" >
