Android Fusedlocationproviderclient not working with APN Sim its working with Wifi or ordinary internet or Offline(Android融合位置提供商客户端不使用APN模拟其使用Wifi或普通互联网或离线)

本文介绍了Android融合位置提供商客户端不使用APN模拟其使用Wifi或普通互联网或离线的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

Android FusedLocationProvider客户端不支持APN SIM(这意味着私有互联网，并非所有人都可以访问)它可以使用Wifi或普通互联网(这意味着全球移动互联网)，我也尝试了位置管理器(Play服务不支持这些设备)。

这是我的样例代码。一旦我连接了我的wifi，它就可以工作了，但我的观点是，我们想要使用APN sim。

推荐答案

答案： 谷歌位置服务使用谷歌的混合位置数据来更快地定位设备的位置。

来自：Do network location provider need internet to determine location?和Google IO 2019视频：Seamless and Smooth Location Everywhere with the new FusedLocationProvider，其中提供了有关FusedLocationProvider的详细信息。

GPS仍然有效，只是定位速度更慢，而且在户外效果最好。AGPS (Assisted GPS)需要移动连接以帮助GPS定位。如果你想要在室内或城市环境中定位，你将需要一个使用Hybrid Positioning的外部服务，该服务使用Wi-Fi、蓝牙，可能还使用手机发射塔？但由于位置数据库不断更新(即WiFi热点发生变化，新的建设可能会改变无线电模式)，因此至少需要一些与外部服务的频繁连接，因此这与在专用网络上访问Google服务存在相同的问题。

我需要将[Google Services]列入白名单的Google URL是什么？

发件人：FCM ports and your firewall：

对于出站连接，FCM不提供具体的IP，因为我们的网段变化太频繁，您的防火墙规则可能会过时，影响您的用户体验。理想情况下，您应该将没有IP限制的端口5228-5230列入白名单。但是，如果您必须有IP限制，则应将Google's ASN of 15169中列出的IPv4和IPv6块中的所有IP地址列入白名单。这是一个很大的清单，你应该计划每月更新你的规则。防火墙IP限制导致的问题通常是间歇性的，很难诊断。

要为传入消息打开的端口：

5228

5229

5230

允许传出连接的端口：

其中之一(首选选项1)：

  1. 无IP限制
  2. Google's ASN of 15169中列出的IP块中包含的所有IP地址。不要忘记至少每月更新一次。

虽然Google服务不是Firebase Cloud消息传递，但它基于相同的不断变化的全球基础设施，因此在没有具体文档说明的情况下是合理的匹配。

另外，鉴于Google Maps不是Google Location Services，请参阅此问题中的Google Maps相关资源：Using google maps api behind firewall

替代方案

另一种选择是不为您的混合位置提供商使用Google服务。有像HERE这样的第三方供应商似乎有自己的高级Advanced Positioning by HERE服务。您必须检查plan would be appropriate for your usage内容，并与他们联系，了解如果What IP-addresses do I need to allow the firewall to access geocoder.api.here.com?

未涵盖哪些IP地址/域需要被列入白名单

可能还有像Skyhook这样的其他提供商可以进行调查，以确定它们是否符合您的需求。我会看看APN SIM提供商是否有服务。或者，如果所有设备都是由一家制造商提供的，请查看该制造商是否有专有(非谷歌)的定位服务。

无法执行上述任何操作

如果企业不允许上述选项，则应用程序仅限于在GPS可用时修复GPS的速度较慢的应用程序。GPS是免费的，但要想更快地定位或改善城市/室内位置，需要一些第三方服务来告诉设备它在哪里。
