問題描述
更新:這是一個 Google Play 服務問題，內部報告這里將從版本 13.4.0 開始修復
Update: it is a Google Play Service issue, reported internally here and it will be fixed from version 13.4.0
我們使用 cordova 地理定位插件 和方法 navigator.geolocation.watchPosition() 帶有選項 enableHighAccuracy: true 以跟蹤用戶位置并獲得最準確的結果.
We use the cordova gelocation plugin and the method navigator.geolocation.watchPosition() with the option enableHighAccuracy: true to track the user location and get the most accurate results.
我們的應用程序已經存在 1 年多了，過去我們可以毫無問題地使用任何設備來獲得非常好的定位精度，戶外時 4/6 米，天空晴朗.
Our app has been around for more than 1 year and we used to have no problems with any device getting a very good location accuracy, 4/6 meters when outside and the sky is clear.
最近，我們的許多用戶報告說，無論他們做什么，都無法獲得低于 10m 的精度.
Lately, many of our users are reporting not being able to get anything less than 10m accuracy no matter what they do.
我們決定自己測試它，我們發現有同樣的問題.最初，我們認為我們在最新版本中引入了一些錯誤，我們對所有內容進行了三次檢查，但我們沒有對涉及地理位置的代碼/依賴項進行任何更改.
We decided to test it ourselves and we found to have the same issue. Initially, we thought we introduced some bug in our latest release, we triple checked everything but we made no changes to code/dependencies involving geolocation.
我們還測試了我們應用的舊版本，我們確信可以達到 4m 的精度，但令人驚訝的是它們也不起作用，精度上限為 10m.
We tested older versions of our app as well, where we are sure it was possible to get like 4m accuracy, but surprisingly they do not work either, accuracy is capped at 10m.
我們嘗試了不同版本的 Android，我們可以在從 5(棒棒糖)到 8(奧利奧)的任何平臺上重現該問題.我們在 iOS 10/11 上也有同樣的問題.同樣，我們已經有幾個月沒有更新該應用了.
We tried different version of Android and we can reproduce the issue on any platform from 5 (Lollipop) to 8 (Oreo). We also have the same problem on iOS 10/11. Again, we have not updated the app in months.
最近有一個關于同一問題的問題 這里:
There is a recent question about the same issue here:
其他人在使用 Android 本機代碼時遇到同樣的問題 這里
Someone else is having the same problem using Android native code here
有人知道發生了什么嗎?是權限問題嗎?定位服務也設置為高精度.
Does anyone know what is going on? Is it a permission issue? Location Services are set to High Accuracy as well.
為了完整起見，我們可以使用這個 插件
For the sake of completeness, we are able to get 3/4 meters accuracy using the old version (2.x) of this plugin
這是唯一的出路嗎?
我們寧愿不為開箱即用的運行良好的東西引入額外的依賴項.
We would rather not introduce an extra dependency for something that was working so well out of the box.
非常感謝
