GPS是不是在建筑物内部工作 [英] GPS is not working inside the building

问题描述

几个小时的房子，外面的测试，当我回到我的房子，我发现GPS已启用，但并没有得到building.Hence内位置修正后的 onLocationChanged 方法不能被调用。

After few hours of testing outside of house, when i came back to my house i found that GPS is enabled but was not getting location fixes inside the building.Hence its onLocationChanged method couldn't get called.

问题：如何知道GPS是没有得到任何位置修复作为设备继续感知尝试模式。通过你的位置，设法模式我的意思是它不来任何情况导致即使在20到30分钟还是它宣布它自身作为启用（在状态栏闪烁）。

Problem: How to know that GPS is not getting any location fixes as device continue to sense your location in "trying mode".By trying mode i mean the situation where it is not coming to any result even after 20 to 30 minutes still it declared it self as enabled (blinking in status bar).

一个人怎么能知道GPS没有得到位置，以便切换到像Network_Provider另一个提供商。

How one could know that the GPS doesn't get location so switch to another provider like Network_Provider.

总之我希望得到我的设备得出结论的东西，GPS可以找到的位置锁定为肯定或者您有通过其他方法采取的位置。

In short i want to get my device to conclude something that GPS can find location fix for sure or you have to take location by another means.

我希望至少有人可以给我关于如何处理这一想法。

I hope at least someone can give me idea about how to deal with that.
