GPS isProviderEnabled always return false

If you are checking for the location is opened or not whatever it is using GPS or not, so you have to pay attention to the following as it was my case, in device location settings the locating method was set to BatterySaving mode, in which the device uses only WiFi mobile networks to estimate location:

Therefore, the GPS is not even used in update location, and so the location icon will not appear in the status bar in addition to the location provider will be stated as Network not GPS.

so, to solve that issue you have to check whether the provider contains gps or contains network:

private boolean checkIfLocationOpened() {    String provider = Settings.Secure.getString(getActivity().getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);    if (provider.contains("gps") || provider.contains("network"))        return true;    }    // otherwise return false    return false;}

and if you want to do it using the LocationManager:

private boolean checkIfLocationOpened() {    final LocationManager manager = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);    if (manager.isProviderEnabled(LocationManager.GPS_PROVIDER) || manager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){        return true;    }    // otherwise return false    return false;}

try this way..

private void turnGPSOn(){   String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);   if(!provider.contains("gps")){          final Intent poke = new Intent();      poke.setClassName("com.android.settings","com.android.settings.widget.SettingsAppWidgetProvider");               poke.addCategory(Intent.CATEGORY_ALTERNATIVE);       poke.setData(Uri.parse("3"));          sendBroadcast(poke);      } }  

some time location manager returns the wrong result.below code works for me.

public static boolean isGpsEnabled(Context context) {        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {            String providers = Settings.Secure.getString(context.getContentResolver(),                    Settings.Secure.LOCATION_PROVIDERS_ALLOWED);            if (TextUtils.isEmpty(providers)) {                return false;            }            return providers.contains(LocationManager.GPS_PROVIDER);        } else {            final int locationMode;            try {                locationMode = Settings.Secure.getInt(context.getContentResolver(),                        Settings.Secure.LOCATION_MODE);            } catch (Settings.SettingNotFoundException e) {                e.printStackTrace();                return false;            }            switch (locationMode) {                case Settings.Secure.LOCATION_MODE_HIGH_ACCURACY:                case Settings.Secure.LOCATION_MODE_SENSORS_ONLY:                    return true;                case Settings.Secure.LOCATION_MODE_BATTERY_SAVING:                case Settings.Secure.LOCATION_MODE_OFF:                default:                    return false;            }        }    }
