Now that we've installed the tools necessary to create and preview the default PhoneGap application, it's worth stopping to take a moment to look through the default application and point out some important details. Open the index. This is used to indicate how much of the screen should be used by the application content and specify how it should scale. Scaling refers to the zoom level, where initial-scale indicates the desired zoom upon load, the maximum-scaleminimum-scale values control the least and most allowed and user-scalable properties control whether a user should be allowed to control the scale or zoom factor via pinch gesture for instance.

In the index. The cordova. Including this file reference ensures the Cordova APIs have access to those features and are available. You may notice that there isn't a cordova. That's because the right version for the platform is injected for you at runtime by the Developer app or the PhoneGap CLI if you're building your projects using the CLI.

You simply need to ensure the reference is available.

The index. This file is not required in your applications, but is specific to this default application and used to add simple logic around determining when the Cordova library has loaded and is ready to be used. More information on that follows in the next section. Notice that the index.

This calls the initialize function on the app variable defined in the index. Open that now before moving on. The other important Cordova-specific feature to point out is the deviceready event. This event signals that Cordova's device APIs have loaded and are ready to access.

If you don't rely on this event and only then start making calls to Cordova APIs then you could end up in a situation where the native code is not yet fully loaded and not available.

The Facebook plugin for Apache Cordova allows you to use the same JavaScript code in your Cordova application as you use in your web application.

However, unlike in the browser, the Cordova application will use the native Facebook app to perform Single Sign On for the user. If this is not possible then the sign on will degrade gracefully using the standard dialog based authentication. Please install the plugin through a locally cloned copy or re-add the FacebookSDK.

This will create a folder named myApp in the current path location with a default project name of Hello World and id of com. You can also specify a name and identifier to ensure the project is unique but still contains the default Hello World code project by specifying them as qualified parameters as shown below:.

You will receive the server address the app is being hosted on in the output received in the console Now go to your mobile device where the PhoneGap Developer App is running, enter the server address on the main screen and tap Connect for the browser you would use localhost as the server address. You should see the connection occur followed by a success message as shown below.

If you receive an error of any kind, ensure once again that you are connected to the same network on both your and computer. You could also check the issue tracker and PhoneGap Google Groups list for further help. The first time you run an app inside the PhoneGap Developer App that requests the permission to receive push notifications you will see the following dialog:. Please click on the OK button to give the app the required permission. Subsequent runs of the application will not show you this permission dialog.

Once the PhoneGap Developer app connects and loads your mobile application, it should be displayed for preview as shown below:. The grey Requesting Registration ID line under the PhongGap Bot should turn into a green Registered line and you should see the following in your terminal session.

All of the code required to register and receive push notifications is in the onDeviceReady function. First we need to initialize the push notification system. The init function sets up the communication path with the remote push service and requests a registration ID. You will need to do this each time your app starts.

Don't worry about requesting a registration ID each time your app starts. The phonegap-plugin-push code is smart enough to use cached registration ID if available. Next we'll setup an event handler for the registration event. Once the app has successfully registered with the remote push service, our event handler will be called.

The event handler is called with one parameter, a data object containing one property; the registrationId received from the remote push service. Then we'll get the value of the saved registrationId from localStorage. If the old registration ID does not match the newly received registration ID we need to do two things. First, save the new registrationId into localStorage.

Second, send the registration ID to your push service. You'll see that the registration event handler updates the HTML to visually display that the app is now registered. Next we'll setup an event handler for the error event.

Cordova Push Notification (Phonegap plugin push) Tutorial

If anything goes wrong with registration the error event will be fired. Finally, we'll setup an event handler for the notification event, called only when the app receives a push notification while running in the foreground.From the team behind Apache Cordovathe Adobe PhoneGap framework is an open source distribution of Cordova — providing the advantage of technology created by a diverse team of pros along with a robust developer community — plus access to the PhoneGap toolset, so you can get to mobile faster.

How could you go wrong?Comment 1. This article shows you how to implement user authentication in a jQuery Mobile and PhoneGap application. User registration which we added in the previous chapter of this series and authentication are the door that users have to go into the application.

The authentication feature has two subsystems that work together. The other subsystem resides on the server. It receives the user credentials sent from the mobile application, authenticates them against profile information stored in a database, and returns a session token back to the app so subsequent requests can be mapped to the correct user in the database.

In this article we are going to create the mobile app side.

First, we are going to review the Sign In screen that we designed in a previous article of this series. This is where users will type their email address and password for authentication purposes. Besides the email address and password fields, the page has checkbox that lets the users indicate if they want to keep their session active after they close the application. When users check this box, they will be accepted in without authentication next time they launch the app from the same device.

This feature requires that we define a session expiration setting in the app. The setting will represent the number of days the session will be active. As you can imagine, we will need to create a similar setting on the server side. We need this so the session token created for users when they sign in remains valid on the server for the same period the session is active on the app.

The session expiration should be the same on both the app and the server side for this feature to work correctly. As a second step, we are going to create the screen where we will take users after they log in successfully. We will name it the Main Menu screen. The screen is a jQuery Mobile page that will add to the index.

In a future article we will add the main menu elements to the page. Remember that we planned for the application to also support users with administrative rights. This means that in the future we will need to add user roles logic to the registration and login features. To keep things as simple as possible, we will not touch this area in this particular article.

The occasionally-connected nature of mobile applications brings along the need to store user information on the application side once you authenticate the user. We will use a Class to encapsulate the storage and retrieval of session data in local storage.

Internally, the Class uses the window. We call the set method to save data, and the get method to retrieve data.Build great apps powered by open web standards.
