AutoComplete Google Places get error :This API project is not authorized to use this API. Please ensure that this API is activated in the APIs Console

我正在尝试使用 Google API.

开发具有自动完成文本视图的地图

我试过这个教程here

但是当我尝试获取 API 时总是会出现此错误:

{
   "error_message" : "This API project is not authorized to use this API. Please ensure that this API is activated in the APIs Console: Learn more: https://code.google.com/apis/console",
   "predictions" : [],
   "status" : "REQUEST_DENIED"
}

我试图找到解决方案,我尝试了所有的解决方案,比如使用 浏览器密钥服务器密钥启用 google 地点和地图删除并重新创建项目,但我仍然遇到错误,这是我的代码:

我看到您正在使用 Places API Web 服务 — 您可能会发现 Android 的 Places API 更适合您,因为您正在编写 Android 应用程序。 Android 的 Places API 将允许您使用 Android 密钥,与服务器密钥不同,它可以限制为仅供您的应用使用。

要使用 Web 服务,请遵循开发人员指南中的 Get a Key 说明。特别要确保您:

  • 使用服务器密钥,并且
  • 已启用 Google Places API Web 服务与Google不同在 Google Developers Console 中为 Android) 放置 API。

https://code.google.com/apis/console用你的id登录, 创建一个应用程序,放置所有详细信息并生成 API 密钥 并将您的 API 密钥放在下面的代码中
// 字符串键 = "Put your API key here ";

private String getAutoCompleteUrl(String place){

        // Obtain browser key from https://code.google.com/apis/console
        String key = "Put your API key here "; here you update your key
    // 

        // place to be be searched
        String input = "input="+place;

        // place type to be searched
        String types = "types=geocode";

        // Sensor enabled
        String sensor = "sensor=false";

        // Building the parameters to the web service
        String parameters = input+"&"+types+"&"+sensor+"&"+key;

        // Output format
        String output = "json";

        // Building the url to the web service
        String url = "https://maps.googleapis.com/maps/api/place/autocomplete/"+output+"?"+parameters;
