I think the problem is that GPS take a fiew second to syncronice. You must to use a thread. Take this example:

@Override
public void run() {

    mLocationManager = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);

    if (mLocationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
        Looper.prepare();
        mToast.Make(getContext(),"GPS",0);
        mLocationListener = new MyLocationListener();
        mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mLocationListener);
        Looper.loop(); 
        Looper.myLooper().quit(); 

    } else if (mLocationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){
        Looper.prepare();
        mToast.Make(getContext(),"Triangulacion",0);
        mLocationListener = new MyLocationListener();
        mLocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, mLocationListener);
        Looper.loop();
        Looper.myLooper().quit();
    }else{
        mToast.Make(context,"No se encuentra señal se procede a mandar un mensaje normal",0);
        Looper.prepare();
        handlerNormal.sendEmptyMessage(0);
        Looper.loop();
        Looper.myLooper().quit();
    }   

}

and a Location Listener

private class MyLocationListener implements LocationListener 
{
    @Override
    public void onLocationChanged(Location loc) {
        if (loc != null) {
            setCurrentLocation(loc);
            handler.sendEmptyMessage(0);
        }
    }  

//...
}
