Java 哪一个是hello world最简单的google API？

最简单的谷歌API调用是什么？谷歌似乎没有问题的关键，他们只是想要一个计费选项设置。这是严格要求的吗？我不打算打击他们的服务器

最后，希望运行一些映射查询。首先，什么是谷歌服务或API映射API

谷歌翻译看起来是一项付费服务：

代码来自a。

据我所知，由于两个原因，我们通常会出现此错误

这可能是project中创建的新应用程序，我们没有启用它。或者，我们超出了每日/总点击数限制

您是否遵循了“云翻译API未在项目中使用”开头的说明“在错误消息中？即使不是付费API，您也必须将API添加到云项目中。我天真地选择了翻译API，但没有意识到它没有免费选项。我的意思是：即使您选择了像Fit这样的免费API，您仍然必须将该API添加到您的项目中。
