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

Answer 1

Just using this, you can check GPS availability

    LocationManager mlocManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);;
    boolean enabled = mlocManager.isProviderEnabled(LocationManager.GPS_PROVIDER);

Answer 2

Think you could use the code in my answer to: Location servise GPS Force closed

It gives you a callback method for GPS first fix and location changes that can be very convenient. This also makes it easy to change the implementation of GPSTracker to switch to network if GPS takes too long to get a first fix.

Answer 3

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.
