这是Java插件ñ我通过PhoneGap的要求。 但它给位置，只有当网络连接。我只需要使用GPS硬件，而不是通过互联网来获得位置。任何帮助??
This is java plugin n I am calling through phonegap . But It gives location only if internet is available. I need to get location only using gps hardware and not through internet . Any help??
我refferred一些与此相关的计算器问题。所以我就知道，GPS将不能在建筑物内的工作。好了，但在我的情况下，它是不是在外面打工也。之前，除非它没有得到最后的已知位置它不工作。一旦有最后一个位置一些如何，然后它开始工作。任何帮助??
I refferred some of the stackoverflow questions related to this. So i got know that GPS will not work inside the building . Ok , but in my case it is not working outside also. Until and unless it is not getting last known location it is not working . Once it has last location some how then it starts working . Any help ??
编辑：根据这个链接<一个href="http://stackoverflow.com/questions/14121197/android-trouble-in-getting-location-coordinates-by-only-using-gps-provider">Android - 麻烦越来越位置，只采用GPS提供商坐标，我可以使用libwlocate。但如何使用它作为PhoneGap的插件？任何帮助??
EDIT : According to this link Android - Trouble in getting location coordinates by only using GPS provider , i can use libwlocate . But how to use that as phonegap plugin ?? Any help ??
任何帮助是极大的AP preciated。
Any help is greatly appreciated.
编辑：怎么样，如果我把一些虚拟lastKnownLocation首次。然后，它会requestForNew一个正确的？
How about if i put some dummy lastKnownLocation for the first time. Then it will requestForNew one right??
推荐答案
您可以要求ONLY GPS像这样...
You can request "ONLY GPS" like this...
LocationProvider gpsProvider = locationManager.getProvider(LocationManager.GPS_PROVIDER);
if(gpsProvider != null){
locationManager.requestLocationUpdates(gpsProvider.getName(), 0, 0, this);
}
Boolean isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
Location lastLocation = null, gpsLocation = null;
if (isGPSEnabled)
gpsLocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
