automatic GPS enabling and disabling in android 4.4 similar to google maps?

Question

Whenever i try to turn on and turn off GPS automatically KITKAT fires java.lang.SecurityException: Permission Denial: not allowed to send broadcast android.location.GPS_ENABLED_CHANGE exception...

from the following answer from stack overflow,, Android device GPS on/off programatically
i came to know,

* For The security purpose Google developer has block above both methods which were previously working fine.

* Hence conclusion is that You can not programmatically start GPS On or Off. 

 This is the code part where exception is thrown,



/** Method for stop GPS **/
    public synchronized void onPauseGPSListener() {
        mLogger.log("Remove GPS Location Update");


 //this Line throws the exception--------------------------------


Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
            intent.putExtra("enabled", false);
            sendBroadcast(intent);
            if (locationclient != null && mlocListener != null) {
                locationclient.removeLocationUpdates(mlocListener);
                locationclient.disconnect();
                locationclient=null;
                mlocListener = null;
            }
            StoptimerForGPSRemoveListener();
            if (mcalMgr.mServerReset == 0) {
                timerForGPSStartListener();
            }
        }

        /** Method for Start GPS **/
        public synchronized void onStartGPSListener() {
            mLogger.log("Start GPS Location Update");
            if (mlocListener == null) {
                mlocListener = new MyLocationListener();
            }
            Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
            intent.putExtra("enabled", true);
            sendBroadcast(intent);
            StoptimerForGPSStartListener();
            if (mcalMgr.mServerReset == 0) {
                initGPSModule(mnFrequency, mfChangeDistance);
            } else {
                mlocListener = null;
                Intent mintent = new Intent("android.location.GPS_ENABLED_CHANGE");
                mintent.putExtra("enabled", false);
                sendBroadcast(mintent);
            }
    }

this is Logcat stack trace,

But my question is when ever i open Google maps , it turns GPS on and off without any prompt from user,,, thing is it only asks for first time when we login to our application, from that onwards it automatically turns on and off the GPS ,, how can i implement the same procedure implemented in google maps , better provide me with code examples thank you

No this isn't the case google map does cache location and usually shows last know location when GPS is not on/enable! — Muhammad Babar, Nov 25 '14 at 12:51
"when ever i open Google maps , it turns GPS on and off without any prompt from user" -- not on my Nexus 4. If GPS is disabled, it pops up a dialog and forces you to go to Settings to enable GPS. Also, please bear in mind that "off and on" is not the same as "enabled and disabled". An app cannot enable or disable GPS. — CommonsWare, Nov 25 '14 at 12:53
but whenever i open google maps notification bar shows GPS icon and disappears... may be can u know the procedure or code used in maps??? — , Nov 25 '14 at 12:54
@CommonsWare is that possible to enable GPS specific for an application only once for first time by asking user with alert and then automatically getting location updates — user39996, Nov 25 '14 at 12:56
No. If the user disables GPS, no apps can use GPS, unless the user goes back into Settings and re-enables it. — CommonsWare, Nov 25 '14 at 12:59
@CommonsWare I'm using Moto G , i have enabled GPS and my google maps using GPS everytime without any prompt , i have installed one more app(my own app) , in my app i'm using a service to turn on and off GPS periodically , so when service has been called to it fires exception , can u suggest me the exact cause of the force close and what to do — user39996, Nov 25 '14 at 13:05
"i have enabled GPS and my google maps using GPS everytime without any prompt" -- correct. If you *disable* GPS, Google Maps will prompt you to enable it, if you do something in Google Maps that requires GPS (e.g., ask for it to highlight your location). " can u suggest me the exact cause of the force close and what to do" -- http://stackoverflow.com/questions/23353173/unfortunately-myapp-has-stopped-how-can-i-solve-this — CommonsWare, Nov 25 '14 at 13:07
@CommonsWare I have updated my question can u plz check , favour me some help and it will thankful — user39996, Nov 25 '14 at 13:16
That is a protected broadcast that can only be sent by the system. — CommonsWare, Nov 25 '14 at 13:36
@CommonsWare do you know (or) having google documentation Link that from 4.4 GPS feature have been under control ... if know plz comment ... — user39996, Nov 26 '14 at 04:26

        }
    }

}
