Android GPS 仅在 Google 地图运行后进行通信

我寻找答案，但没有找到答案 - 我的问题如下：

我编写了与模拟器一起使用的代码（我通过 DDMS 发送本地坐标）。

该代码也适用于设备但是，只有在运行 Google 地图之后。我猜清单或代码中缺少一些东西，但我不知道它是什么，我可以使用一些建议/建议。

以下是代码相关部分的片段： （我无法弄清楚如何正确嵌入这些东西，所以它看起来很智能/有组织，但是，我认为你明白了......）

homeboy = (LocationManager)getSystemService(Context.LOCATION_SERVICE);    
locationListener = new MyLocationListener();
Location recentLoc = homeboy.getLastKnownLocation(LocationManager.GPS_PROVIDER);

I also have a LocationListener method (shown w/o it's four methods of checking for enabled, changed,...etc)
private class MyLocationListener implements LocationListener {
... etc.

I include this in the manifest file near the top:
<uses-permission 
android:name="android.permission.ACCESS_FINE_LOCATION" />

那么，缺少什么？另外，如何从 wifi 获取位置（例如通过任何可用的方式获取位置，除了将最后一个位置保存到文件并检索它之外）。

感谢您的任何意见

I looked for the answer but didn't find one - my question(s) follow:

I wrote code that works with the emulator (I send local coords vis DDMS).

The code also works on the device BUT, only after running Google Map. I'm guessing there's something missing in either the manifest or in the code but I don't know what it is and I could use some advice/suggestions.

Here are snippets of the relevant portions of the Code:
(I wasn't able to figure out how to properly embed this stuff so it looked intelligent/organized but, I think you get the point...)

homeboy = (LocationManager)getSystemService(Context.LOCATION_SERVICE);    
locationListener = new MyLocationListener();
Location recentLoc = homeboy.getLastKnownLocation(LocationManager.GPS_PROVIDER);

I also have a LocationListener method (shown w/o it's four methods of checking for enabled, changed,...etc)
private class MyLocationListener implements LocationListener {
... etc.

I include this in the manifest file near the top:
<uses-permission 
android:name="android.permission.ACCESS_FINE_LOCATION" />

So, what's missing?
Also, how to get location from wifi (as in getting the location by any means available short of saving the last location to a file and retrieving it).

Thanks for any input
