我正在尝试通过发布/订阅库将数据发送到GoogleCloud中的主题

I'm try to send data throught pub/sub library to my topic in GoogleCloud

projects/navigator-cloud/topics/navigator-location

这是Google地图的一个项目，其中包含建筑物的叠加层图像，我应该使用它.我想发布包含以下信息的JSON: {"Username":"oscarhmg"，"Location":"labproto"，"Timestamp":"2016-12-04T15:29:05Z"} .

Here is a project of a google map with a overlay image of a building, which I should use. I want to publish a JSON with some info like this: {"Username": "oscarhmg", "Location": "labproto", "Timestamp": "2016-12-04T15:29:05Z" }.

当主题收到此信息时，建筑地图中会显示一个标记(此地图在我的应用程序中以网络视图显示).该功能已经实现，我仍然不了解的是如何通过我的android应用程序传递消息以发布有关此主题的消息.任何帮助将不胜感激

When the topic receive this info, in the building map appears a marker(This map shows in my application in a web view). This functionality is already implemented, what I still do not understand at all is how to pass the message to publish on this topic through my android application. Any help would appreciate it
