java - 从 Google map 请求 JSON 给我 REQUEST_DENIED

Question

我想知道为什么我的请求总是被拒绝。我很确定我的 API key 是正确的，我在 Google Console 中选择了 android，用我的项目名称为其提供了 sha1，并获取了 API key 并将其粘贴在我的项目中。但是，如果我尝试任何操作，它仍然会不断给我 REQUEST_DENIED 。我假设这与我构建 URL 的方式或基本 URL 是否损坏有关，或者可能与我请求数据的方式有关。

我对此很陌生，几天前才开始玩，所以任何帮助将不胜感激。

这是我的代码 -

请按照以下步骤操作:

Google 控制台:

API 和身份验证 -> API(Google Places API Web 服务)已启用。

API 和身份验证 -> 凭据 -> 创建新 key -> 浏览器 key (您需要创建浏览器 key 而不是 Android key 。)。

对于浏览器 key ，您不需要使用 Sha1 创建特定 key 。
