Android的全球定位系统。位置监听器并不想获得一个修复:( [英] Android GPS. Location Listener does not want to acquire a fix :(

问题描述

下面是低于一个code假设监听GPS更新和发送通知的主要活动

Here is a code below that suppose to listen for GPS updates and send notifications to main activity

但它似乎并不奏效：）

没有错误，仅onLocationChanged不叫！

No errors, only onLocationChanged is not called!

有趣的是：当我运行其他应用获取GPS定位，之后开始我的应用程序=> onLocationChanged被调用，只是精度降解，最终弄不好会丢失

Funny thing is: when I run some other app to get GPS fix and after that start my app => onLocationChanged gets called, only accuracy is degrading, and eventually fix is lost.

我也试图添加到此code GPS监听器=>它的工作原理，针对卫星的报道得到了每秒，唯一的解决方法是从来没有accuired。

I also tried to add to this code GPS listener=> it works, satellites in view got reported every second, only fix is never accuired.

这到底是怎么回事？ ：）

What the hell is going on? :)

推荐答案

好吧，搞清楚这是也被其他人看到的一个问题：显然是（至少在某些手机上），GPS监听工作，如果相机是非常糟糕活动的。

Ok, figure out that this is an issue that was also seen by other people: apparently (at least on some phones) GPS listener works much worse if Camera is active.
