推荐答案

该位置可能由于多种原因而丢失：

The location can become lost for a wide variety of reasons:

• 设备不再具有对天空的合理开放权限，因此GPS卫星信息不可用。

• The device no longer has reasonably open access to the sky so GPS satellite information is unavailable.

没有足够的蜂窝塔来执行三角测量。

There aren't enough cell towers available to perform triangulation.

wifi接入点不在已知接入点的数据库中。

The wifi access point isn't in the database of known access points.

用户切换到飞行模式。

还有更多。位置感知应用程序必须假设它们会随时丢失地理位置信息。它通常会在片刻之后返回。

And many more. Location-aware applications have to assume they'll lose geolocation information at any time. It often comes back moments later.
