Find my phone! on{X} style

I've been toying with the new app / scripting abilities Microsoft have put together for Android. Yes, that is correct, your eyes do not deceive you. Microsoft have released an app, called on{x}, that allows you to write a Javascript to perform certains actions on your Android device at x time, x event (such as when a text message is received) or when your Mode of Transport changes - if nothing else this one is interesting for sure!

Install on{x} from the Play Store here

I had a look at the 'Recipes' as they're called that Microsoft 'baked' and released for use an decided to take one of their recipes, hack it a little - not too much ! - so it texts a bunch of people to let them know your phone has been stolen. I'll post other examples of modified scripts here too, I say modified because, well I never learnt Javascript, but understand enough to chop and change bits of it.

Add in as many friend variables with different names as you want in the top, remove the double slash to uncomment the variable friend2.

There is an email & texting version of this script in the works.

// Initializing variables
   
 var friend = { name : "Self",phoneNumber : "+441234567890" } ;
//    var friend2 = { name : "Otherhalf",phoneNumber : "+441234567809" } ;
 var messageText = "where?";

 // End of variables initializing

 console.log('Started script: When ' + friend.name + ' texts me \"' +  messageText + '\" reply automatically with my location');

    //  Register callback on sms received event
    device.messaging.on('smsReceived', function (sms) {
        if (sms.data && sms.data.body.toLowerCase() === messageText.toLowerCase()) {
            // getting location from cell, which is accurate enough in this case, time interval is 100  milliseconds, to get immediate location sample
            var locListener = device.location.createListener('CELL', 100);
            locListener.on('changed', function (signal) {
                // stop listening to location changed events after getting the current location
                locListener.stop();

                var mapUrlPattern = 'https://feeds.onx.ms/maps?wp=lat,lon';
                var mapUrl =  mapUrlPattern.replace(/lat/g, signal.location.latitude).replace(/lon/g, signal.location.longitude);

                // sending text message  with the current location ro predefined numbers in the initializing variables section up top
               
                device.messaging.sendSms({
                        to: friend.phoneNumber ,
                        body: 'I am here, come get me! ' + mapUrl
                    },

/* Remove the comments from the below section, the slash and star's to enable the second person to text, copy and past the code below between the slash and star, replace the friend2 with another variable name defined at the top to text another person, enable a many of these alerts as you want! */

               /*device.messaging.sendSms({

                        to: friend2.phoneNumber ,
                        body: 'I am here, come get me! ' + mapUrl
                    }, */
               
               
                // reply to sender with current location     
                device.messaging.sendSms({
                        to: sms.from ,
                        body: 'I am here, come get me! ' + mapUrl
                    },       
                   
                    function (err) {
                        if (err) {
                            console.error('Error sending text message: ' + JSON.stringify(err));
                        }
                    }
                ));
            });
            locListener.start();
        }
    });
    console.log('Completed script: When ' + friend.name + ' texts me \"' +  messageText + '\" reply automatically with my location');
