Android：获取附近的所有城市、城镇、邮政编码

Question

我需要查找从经纬度指定的地点半径20公里内的所有城市、城镇或邮政编码。

我已尝试使用 Google Places API 中的 Places search 进行此查询：

https://maps.googleapis.com/maps/api/place/radarsearch/json?location=53.09022140,21.21483510&radius=20000&types=(locality|postal_code)&sensor=false&key=myKey

但这似乎不适用于地理编码地点（仅显示业务结果）。

我还在 Google Maps JavaScript API v3 的 Places Library 中阅读了关于 Place Searches 的信息，但我不确定这是否适用于 Android 应用程序（我有一个 http/php 服务器，但我不确定我如何将它与我的 Android 应用程序一起使用）。我可以直接从我的应用程序中使用它吗？

也许我可以使用其他服务来实现它？你有什么建议吗？

我知道这个问题已经很老了，但由于还没有人回答，所以我想我会分享一下我是如何解决这个问题的。

有几种方法可以解决这个问题。第一种是使用此处提供的信息创建您自己的地点数据库：http://download.geonames.org/export/dump/

这不是太难，但如果你没有时间，可能会很痛苦。

还有很多第三方服务可以为您做到这一点。我运行了一项名为 https://geo-info.co/

的服务

在这种情况下，我们几乎可以完全满足您的需求。
