Question

问题：

我尝试使用新的FusedLocationProviderClient和已弃用的FusedLocationApi使用 Sony Xperia Z2 和 Huawei Honor 8 接收我的应用上的位置更新。一切都很好。但是，似乎在x位置请求后，使用location.getAccuracy(); // 10.0

的精确度数从不降至10.0以下

我尝试了什么：

卸载并重新安装应用程序没有任何区别。重启手机，结果相同。是的我有LocationRequest.PRIORITY_HIGH_ACCURACY ......没有不同的结果。

可行的方法：

工厂重置了吗？ Whooppaa突然我现在得到的数字低于10.0，正如预期的那样，外面有明显的条件。但为什么??

问题：

我怀疑系统在x位置更新后限制了我的准确性（为了节省电池???）......你们怎么想？这可能是什么问题？

修改

在手机上进行软件重置后，我再次获得低于10的准确度数字。但是，在x个位置更新后，精度数量再次限制在10.0米。我应该说我的GPS设计为一次可以运行前景长达3.5小时。是的，我知道这是电池耗尽。

    public void onLocationChanged(Location location) {
        // New location has now been determined
        String msg = "Updated Location: " +
                String.valueOf(location.getAccuracy());
        Toast.makeText(this, msg, Toast.LENGTH_SHORT).show();
        // You can now create a LatLng Object for use with maps
        LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());

        Log.d("GPS: ", String.valueOf(location.getAccuracy()));
    }

}

location.getAccuracy（）的奇怪和非常意外的问题
