i try to get gps data. But gps data return null value. When i looked, following 'location' is return null, so i could not get gps data.
location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
My code is following;
protected LocationManager locationManager;
public GPSTracker(Context context) {
this.mContext = context;
getLocation();
}
public Location getLocation() {
try {
locationManager = (LocationManager) mContext.getSystemService(LOCATION_SERVICE);
// getting GPS status
isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
// getting network status
isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (!isGPSEnabled)
{
}
else if (!isGPSEnabled && !isNetworkEnabled)
{
}
else
{
this.canGetLocation = true;
if (isGPSEnabled) {
if (location == null) {
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
Log.d("GPS Enabled", "GPS Enabled");
if (locationManager != null) {
location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
}
}
}
i wait your help. Thanks

I changed like following code, then worked successfully.
String bestProvider = locationManager.getBestProvider(criteria, false);
locationManager.requestLocationUpdates(bestProvider, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
if (locationManager != null) {
location = locationManager.getLastKnownLocation(bestProvider);
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
}
}

Have you set these in your manifest?
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
