[英]Titanium Geolocation Not Working in Android Emulator
I get this error: 我收到此错误:
[ERROR][GeolocationModule( 278)] (KrollRuntimeThread) [633,2564] Unable to get current position, location is null
[错误] [GeolocationModule(278)](KrollRuntimeThread)[633,2564]无法获取当前位置,位置为null
and I have followed other people's advice without any luck. 我听从别人的建议,没有任何运气。
Could someone lead me in the right direction? 有人可以引导我朝正确的方向前进吗? I would be so grateful.
我将非常感激。 Thank you!
谢谢!

It took me some time to track this down, but I think I've found the steps needed to "fix" the lack of a location in the Android emulator (from this answer ): 我花了一些时间来跟踪它,但是我想我已经找到了“修复” Android仿真器中位置不足所需的步骤(来自此答案 ):
First, open ddms (Dalvik Debug Monitor).
首先,打开ddms(Dalvik调试监视器)。 On Windows, navigate to the android-sdk\\tools directory and run ddms.bat.
在Windows上,导航至android-sdk \\ tools目录并运行ddms.bat。 The first line in the top-left pane will read something like "emulator-####" such as emulator-5560.
左上方窗格的第一行将显示类似“ emulator-####”的内容,例如emulator-5560。
Open a command prompt window.
打开命令提示符窗口。 Enter 'telnet localhost ####' substituting the number you found above.
输入“ telnet localhost ####”替换上面找到的数字。 This will open a telnet window to your android emulator.
这将打开一个telnet窗口到您的android模拟器。
Enter the following command (substitute your own longitude & latitude, in that order, if you'd like):
输入以下命令(如果需要,请依次替换您自己的经度和纬度):
geo fix -82.411629 28.054553
(I'm pretty sure you can add elevation as a third number.) The GPS icon will appear in the emulator's notification bar.
(我很确定您可以将海拔高度添加为第三个数字。)GPS图标将出现在模拟器的通知栏中。 Geolocation is now available.
现在可以使用地理位置。 At this point, I could get location data in my app and in other apps, such as Maps.
此时,我可以在我的应用程序和其他应用程序(例如地图)中获取位置数据。
