Avinash I believe you are from India. Why is that important? because in India even on outside I was not able to get the location from GPS via LocationManager I have ran so many tests on GPS from LocationManager. It seems to return location very rarely from GPS provider.

Solution
Use LocationClient (Google Play services) to retrieve the current location. Google play services are very accurate and retrieves location from Network, GPS and Wifi, If available. And there are more chances that you can Location. Follow this guide

Change order and conditions.

Your code is..

if (enable_network)
{
  // get location from network provider
}

if (enable_gps)
{
  // get location from gps provider
}

Your code always receive location from network provider(if it was on).

So, you should check gps provider condition first and check network provider next.

Change code like this

if (enable_gps)
{
  // get location from gps provider
}
else (enable_network)
{
  // get location from network provider
}
else
{
  // can not receive location data
}
