How to get permissions on runtime for older API versions?

Question

So I've been trying to get started on a simple GPS application but at some point I'm required to ask for user permission on locationManager methods

if (isNetworkEnabled) {
                    locationManager.requestLocationUpdates(
                            locationManager.NETWORK_PROVIDER,
                            MIN_TIME_BW_UPDATES,
                            MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
                if (locationManager != null) {
                    location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                    if (location != null) {
                        Latitude = location.getLatitude();
                        Longitude = location.getLongitude();
                    } //location
                } //locationManager
            } //isNetworkEnabled

I understand that there's a simple way to do it for API 23, but I'd like to target Android 4.0.

I've seen a documentation about it ( https://developer.android.com/training/permissions/requesting.html ) but I just don't quite understand how to apply it to my code. I know I'm supposed to use ActivityCompact and ContextCompact but I'm just not sure on how. Please help!

As you pointed out, Android API >= 23 added the new runtime permissions .

For older API the user is promped to accept them all on installation

like in the image below

You just need to add them in the manifest and nothing else :)
