Tutoriales para novatos

A few days ago I been working on a project of how to use IBM Bluemix Push service with phonegap and I found pretty hard to figure it out how to do it, so I decided to make this post for others like me who are struggling with it, so here you go, a step by step guide of how to configure Bluemix Push notifications with Phongap

NOTE: this tutorial does not explain how to create a bluemix account

Go to bluemix and sign in

The first step will be create a app. Go to DASHBOARD tab and click on the Create APP button

Choose Web app type

I choosed APS .NET 5 just because I like .NET :P

Press Continue button

Type the name you like and press FINISH

Then just wait the app creation process to complete, the we should add the requiered services, I will show you how. Click on Overview in the left menu and the on ADD A SERVICE OR API

Bluemix push notifications require tow services to work Mobile Application Security and Push. The Mobile Application Security should be added before Push otherwise you will get and error when adding Push

Search for the Push service shown below in the Mobile category

After clicking on Mobile Application Security give it a name you like or just leave the suggested value, then hit Create button

After creation we will be promted to restage our app, but we will do this after adding the Push service so press Cancel for now

Then go back to Overview and click on ADD A SERVICE OR API again but click on Push service this time, give it the name you like and hit create. Now Restage the app to get our services up and running

Now, we have our sevices up and running, lets set the Cloud Messaging for Android credentials

Note: If you need help creating your google api credentials you can use follow this tutorial

Select Push service

In the Configuration tab press Edit button under Google Cloud Messaging

Fill in the form with the google api info

Now, Bluemix back-end is all set, lets build the phonegap part

Note: If you need to learn how to install phonegap you can follow this usefull phonegap install tutorial on windows

First of all, lest create a simple phonegap project

$ phonegap create hello com.example.hello HelloWorld

as you will see, phonegap have just created a new project inside the hello directory

move your working directory to hello with the $ cd hello command, after that use the following command to add a new platform to the project (android in this case)

$ phonegap platform add android@3.6.4

You should get something like this

For this part we need to use the bluemix push phonegap plugins, lets download them

$ phonegap plugin add https://hub.jazz.net/git/bluemixmobilesdk/ibmbluemix-cordova
$ phonegap plugin add https://hub.jazz.net/git/bluemixmobilesdk/ibmpush-cordova

NOTE: Take care of the plugins instalation order or you may get some weird errors like IBMLogger is not defined I also recommend using git url insted package name so you can get version 1.0.0-20150720-1718 instead of 1.0.0-20140625-1909 to avoid some troubles I ran into

Now we can add our push regitration js code. Open index.js located inside <path to project>/<project name>/www/js/

and replace all the app object with the following

var app = {
    // Application Constructor
    initialize: function() {
        this.bindEvents();
    },
    // Bind Event Listeners
    //
    // Bind any events that are required on startup. Common events are:
    // 'load', 'deviceready', 'offline', and 'online'.
    bindEvents: function() {
        document.addEventListener('deviceready', this.onDeviceReady, false);

    },
    // deviceready Event Handler
    //
    // The scope of 'this' is the event. In order to call the 'receivedEvent'
    // function, we must explicity call 'app.receivedEvent(...);'
    onDeviceReady: function() {
        app.bluemixpush();
    },
    alertNotification: function(message) {

        IBMBluemix.getLogger().info("Received notification");
        alert(JSON.stringify(message));
    },
    bluemixpush: function() {
        console.log("device is ready, let's initialize bluemix!");
        var values = {
            applicationId: "<INSERT_APPLICATION_ID_HERE>",
            applicationSecret: "<INSERT_APPLICATION_SECRET_HERE>",
            applicationRoute: "<INSERT_APPLICATION_ROUTE_HERE>"
        };
        IBMBluemix.initialize(values).then(function() {

            return IBMPush.initializeService();
        }).then(function(pushObj) {

            pushObj.registerDevice("CordovaTest", "SampleTester", "app.alertNotification").done(function(response) {
                IBMBluemix.getLogger().info("Device successfully registered: " + response);
            }, function(err) {
                IBMBluemix.getLogger().error("ERROR REGISTERING DEVICE!:" + err);
            });
        }).catch(function(err) {

            IBMBluemix.getLogger().error("Error initializing the Push SDK or registering device: " + err);
        });
    }
};

NOTE: Be careful of not deleting the app.initialize() instruction at the bottom of your javascript file if you have it, but don't worry if you don't, it should be at the bottom of the index.html

Or maybe is here

Go back again to bluemix and click on Mobile Application Security service menu to obtain the applicationId and applicationSecret

The applicationRoute values can be found here

now lets test our code. You can use this command to deploy the app on your device (first check if you already got the drivers installed and usb debugging enabled) then use

$ phonegap build

and then

$ phonegap run android --device

Troubleshoot: check if your device is connected and reconized using adb.exe located in %USERPROFILE%\AppData\Local\Android\android-sdk\platform-tools and the command adb devices

You should get something like this

Everything should be working now and our device must be registed at bluemix, lets check that out. Go to https://console.ng.bluemix.net and click on DASHBOARD

select the app we created

then click on the Push service

and you should see the device id under de Registrations tab

TIP: At the time of this post was made IBM Bluemix JS SDK is not to be the component that must be used to subscribe a device for Bluemix push notifications, see this comment
