无法在设备上获取 GPS 读数
我已经花了几天时间尝试使用 Android 设备获取位置。由于 API 级别较高，我无法使用 requestSingleUpdate。由于准确性问题，我也不想单独使用 getLastKnownLocation 。因此我选择使用 requestLocationUpdates。
（为简单起见，我将参考此代码，但我使用了多种方法来使用 GPS 来使用 requestLocationUpdates：在 Android 上获取用户当前位置的最简单、最可靠的方法是什么？）
我可以使用手机信号塔获取位置，但其准确性不够好。每当我尝试获取 GPS 位置时，即使我让监听器离开 5 分钟，onLocationChanged 也永远不会被调用。在 GPS 读取部分期间，GPS 图标确实出现在我的通知栏中。我确实设置了获取粗略+精细位置的权限，并且我的 GPS 在 Google 地图和 GPS 测试中运行良好。即使我去谷歌地图获得准确的锁定然后切换到我的应用程序，我也永远不会得到位置更新。我向我认识的人询问了解决方案或原因，但没有得到答复。我也在网上进行了很多搜索以寻求解决方案，但空手而归。我是否遗漏了什么，或者我永远无法获得更准确的位置读数？
I have been working for days in attempting to obtain a location using Android devices. I cannot use requestSingleUpdate due to a high API level. I also do not want to use getLastKnownLocation by itself due to accuracy issues. Therefore I have opted for using requestLocationUpdates.
(For simplicity I will refer to this code, but I have used many approaches to using requestLocationUpdates using GPS: What is the simplest and most robust way to get the user's current location on Android?)
I can get a location using the cell towers, but its accuracy is not good enough. Whenever I try to obtain a location for GPS onLocationChanged is never called, even if I let the listener go for 5 minutes. The GPS icon does appear in my notification bar during the GPS reading part. I do have permissions set for getting a coarse+fine location, and my GPS is working fine in Google Maps and GPS Test. Even if I go to Google Maps to get an accurate lock then switch to my application, I never get a location update. I have asked people I know for a solution or a reason and have been left without a response. I also have done many searches around the net for a solution and have left empty-handed. Is there anything that I am missing or am I never going to get a more accurate location reading?

您提到您已设置获取精细位置的权限，但是获取粗略位置又如何呢？一个好的实现将在可能的情况下使用精细位置更新，在不可能的情况下使用粗略的位置更新。仅仅因为显示 GPS 图标并不意味着您有锁。

You mention that you have permissions set for getting FINE locations, but what about getting COARSE locations? A good implementation will use FINE location updates when possible and COARSE location updates when not. Just because you have a GPS icon showing does not mean you have a lock.
