尝试每5分钟更新一次位置以跟踪用户的位置。
尝试将优先级设置为PRIORITY_HIGH_ACCURACY，删除了setExpirationDuration并使用了前台服务

以下代码从“活动”请求位置更新服务
Intent intent = new Intent(this, ForegroundLocationService.class);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
this.getApplication().startForegroundService(intent);
} else {
this.getApplication().startService(intent);
}
我正在设备中的txt文件中记录位置更新，但几个小时后它停止发送位置。
我在代码或任何解决方案中做什么错了？
