位置未在 10 分钟间隔内更新
Posted
技术标签:
【中文标题】位置未在 10 分钟间隔内更新【英文标题】：Location not updated on 10 mins of interval 【发布时间】：2021-10-22 12:08:24 【问题描述】：我想跟踪用户位置。所以我编写了一个代码，以便每隔 10 分钟它的位置应该在服务器上命中。如果它没有移动，该位置也应该以 10 分钟的间隔命中。我将位置间隔分钟设置为 10 分钟 public static final long LOCATION_INTERVAL_MINUTES = 10 * 60 * 1000; 它应该用 10 分钟更新位置，但它是随机命中的。我还将 gps 频率距离从 10 增加到 gpsFreqInDistance = 100 。随机命中被停止，但它不会在 10 分钟的间隔内更新。 那么如何以 10 分钟的间隔获取位置。 以下是我的清单
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" /
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
对于 10 版本以上的 Android，您不能同时使用后台位置和前台位置。所以我在我的项目中评论了“ACCESS_BACKGROUND_LOCATION”。

【问题讨论】：
从哪里调用这个方法？你是传递应用程序上下文还是活动上下文？ @Arunachalamk- 我正在传递应用程序上下文 【参考方案1】：为什么你在最后一个参数中传递 null？你试过没有通过吗？
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, AUtils.LOCATION_INTERVAL,
gpsFreqInDistance, this, null);
首先，Google Location Services 在实现这一要求方面远优于传统的 LocationManager。

【讨论】：
@Arunachalam-不，我没试过。你认为这对我有用吗。 @gopssays 请分享您用于 Google 定位服务的代码 sn-p 我使用的是 LocationManager 而不是谷歌位置服务以上是关于位置未在 10 分钟间隔内更新的主要内容，如果未能解决你的问题，请参考以下文章
