How can I check the current status of the GPS receiver?

Question

How can I check the current status of the GPS receiver? I already checked the LocationListener onStatusChanged method but somehow it seems that is not working,

I know this is a little late. However why not use the NMEAListener if you want to know if you have a fix. From what I've read, the NMEAListener will give you the NMEA sentences and from there you pick the correct sentence.

The RMC sentence contains the fix status which is either A for OK or V for warning. The GGA sentence contains the Fix Quality (0 invalid, 1 GPS or 2 DGPS)

I can't offer you any java code as I'm only just starting out with Android, but I have done a GPS library in C# for Windows apps, which I'm looking to use with Xamarin. I only came across this thread because I was looking for provider information.

From what I've read so far about the Location object I'm not all that comfortable about methods like getAccuracy() and hasAccuracy(). I'm used to extracting from the NMEA sentences HDOP and VDOP values to determine how accurate my fixes are. Its quite common to have a fix, but have a lousy HDOP which means your horizontal accuracy is not very good at all. For example sitting at your desk debugging with an external Bluetooth GPS device hard up against a window, you are quite likely to get a fix, but very poor HDOP and VDOP. Place your GPS device in a flower pot outside or something similar or add an external aerial to the GPS and immediately you get good HDOP and VDOP values.
