How to detect when user turn on/off GPS state?

Question

I want to block the user from changing WiFi, GPS and loading settings from my application. The user need not on/off WiFi and GPS while running my application.(From notification bar). Is there any BroadcastReceiver exist for listening GPS on/off?

Answer 1

Well I did a lot of digging and found that addGpsStatusListener(gpsStatusListener) was deprecated in API 24. And for me, this didn't even work! So, here is another alternative solution to this.

If in your app, you want to listen to the GPS state change (I mean On/Off by user). Using a Broadcast surely is the best approach.

Implementation:

/**  * Following broadcast receiver is to listen the Location button toggle state in Android.  */ private BroadcastReceiver mGpsSwitchStateReceiver = new BroadcastReceiver() {     @Override     public void onReceive(Context context, Intent intent) {          if (intent.getAction().matches("android.location.PROVIDERS_CHANGED")) {             // Make an action or refresh an already managed state.         }     } }; 

Don't forget to register and unregister this efficiently in Fragment/Activity Lifecycle as well.

registerReceiver(mGpsSwitchStateReceiver, new IntentFilter(LocationManager.PROVIDERS_CHANGED_ACTION)); 

For example, if you are using this a Fragment, register it in the onResume and unregister in the onDestroy. Also, if you are directing user to the settings to enable the Location Switch, unregistering in the onStop will not function since, your activity goes to onPause and Fragment is stopped.

Well there may be many answers for this solution but this one is easy to manage and use. Propose your solutions if any.

Answer 2

You can listen the GPS status with a GpsStatus.Listener and register it with the LocationManager.

LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); lm.addGpsStatusListener(new android.location.GpsStatus.Listener() {     public void onGpsStatusChanged(int event)     {         switch(event)         {         case GPS_EVENT_STARTED:             // do your tasks             break;         case GPS_EVENT_STOPPED:             // do your tasks             break;         }     } }); 

You need to have access to the context (for example in an "Activity" or "Application" class).
