Listen to location access disable/enable in settin

问题:

In Android OS, in "Settings" --> "Location services", there is a toggle button named "Access to my location" which can be used to disable & enable location info access from apps.

Currently, I am developing a location service application. I am wondering, how can I listen to this setting in my Android project? Is there any broadcast receiver I can use to know right away when user disable or enable "Access to my location" ?

If there isn't any broadcast receiver for it, how can I listen to this change in my Android project?

This works for me:

Add receiver to the Manifest file:

<receiver
        android:name="com.eegeo.location.LocationProviderChangedReceiver">
        <intent-filter>
            <action android:name="android.location.PROVIDERS_CHANGED" />
        </intent-filter>
    </receiver>

Check both location providers in receiver:

public class LocationProviderChangedReceiver  extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {

        boolean anyLocationProv = false;
        LocationManager locationManager = (LocationManager) MyMainActivity.context.getSystemService(Context.LOCATION_SERVICE);

        anyLocationProv |= locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
        anyLocationProv |=  locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

        Log.i("", "Location service status" + anyLocationProv);


    }

}

Though this receiver is called more than once due to obvious reasons, but this will tell you the status.

You can do it much simpler this way. In your BroadcastReceiver's onReceive() method:

    ContentResolver contentResolver = getContext().getContentResolver();
    // Find out what the settings say about which providers are enabled
    int mode = Settings.Secure.getInt(
            contentResolver, Settings.Secure.LOCATION_MODE, Settings.Secure.LOCATION_MODE_OFF);

    if (mode == Settings.Secure.LOCATION_MODE_OFF) {
        // Location is turned OFF!
    } else {
        // Location is turned ON!
    }

~Thanks to this code: LocationManagerTest.java

You can use the below code to check whether Location Service Enable or not

 LocationManager lm = null;
 boolean gps_enabled,network_enabled;
    if(lm==null)
        lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
    try{
    gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
    }catch(Exception ex){}
    try{
    network_enabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
    }catch(Exception ex){}

   if(!gps_enabled && !network_enabled){
        dialog = new AlertDialog.Builder(context);
        dialog.setMessage(context.getResources().getString(R.string.gps_network_not_enabled));
        dialog.setPositiveButton(context.getResources().getString(R.string.open_location_settings), new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                // TODO Auto-generated method stub
                Intent myIntent = new Intent( Settings.ACTION_SECURITY_SETTINGS );
                context.startActivity(myIntent);
                //get gps
            }
        });
        dialog.setNegativeButton(context.getString(R.string.Cancel), new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                // TODO Auto-generated method stub

            }
        });
        dialog.show();

    }
