获取Android应用程序

Question

我正在xamarin工作室中构建一个Android应用程序，它正在使用像Newtonsoft.Json等第三方库。它运行良好。然后需要将谷歌地图集成到应用程序中。因为我刚开始在Android应用程序中集成谷歌地图，我搜索帮助并使用它们。我在我的代码中使用GoogleMap类。我已在解决方案中安装了Google Play服务（地图）。从那时起，我遇到了部署错误。当我清理项目时，它是成功的。当我重建项目时，它也是成功的。它没有显示错误。但是当我尝试从xamarin studio运行应用程序时，它告诉我发生了部署错误。

如果我尝试将成功构建的apk拖动到正在运行的模拟器，我会收到证书错误。

在这种情况下该怎么做。

谢谢。

以下是我的构建输出。请注意，当我尝试运行应用程序时，我的构建失败。但是，当我只是构建或重新构建应用程序或清理应用程序时，我获得了Build Successful

构建输出
