How can I check if GPS is enabled before I try to use it

Question

I have the following code and it's not good because sometimes GPS takes very long

How can I do the following:

1. Check if GPS is enabled
2. Use GPS if it is enabled otherwise use the network provider.
3. If GPS takes more than 30 seconds, use network.

I can do this with my own logic using a time or Thread.sleep but I think there might be a more stabndard way

// Acquire a reference to the system Location Manager
            LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

            // Define a listener that responds to location updates
            LocationListener locationListener = new LocationListener() {
                public void onLocationChanged(Location location) {
                  // Called when a new location is found by the network location provider.
                    locationCallback(location);
                }

                public void onStatusChanged(String provider, int status, Bundle extras) {}

                public void onProviderEnabled(String provider) {}

                public void onProviderDisabled(String provider) {}
              };

            // Register the listener with the Location Manager to receive location updates
            locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);

There's no standard way, you have to do it on your own with the help of:

    if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)){
        //Do what you need if enabled...
    }else{
        //Do what you need if not enabled...
    }

And this permission in manifest:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

As recommendation if GPS is not enabled, usually the standard specifies to popup the Location Settings Activity so the user can specifically enable it...

Hope this helps.
