Advanced Windows Store Apps Development – II  Explain Trial Functionality  Describe the process of In-app Purchase  Explain the process of Advertising in Windows Store apps © Aptech Ltd Generating Revenue Apps/Session When users selects free trial or try from an app, the user is allowed to use the app up to certain period, which may vary from to 30 days If the trial period ends, same user cannot use that app anymore unless the app is purchased Implementing the trial functionality for an app will help the user in marketing the app, and Microsoft Apps Store recommends it It is recommended to implement these trial functionalities in an app so that user can get a chance to evaluate the app © Aptech Ltd Generating Revenue Apps/Session 3 Time-Based Trials To set a trial-based app, the user has to set a time or date calculation mechanism in the store app The store will take care of the app when the trial period ends, so the developer need not worry about the usage of the app after trial period While submitting the app in the store the developer has to specify the trial period in days for the app as shown in figure The trial period starts when the user downloads and installs the app from the store © Aptech Ltd Generating Revenue Apps/Session Feature-Differentiated Trials When the app trial period expires, the developer can display a message to the customer regarding the expiry of the trial period or send a notification in advance The developer has to send these reminders using the time-based trial period To check whether the app is in trial license, the developer can write code as shown in following Code Snippet Code Snippet: // function to check the licenseinfo private async void fnLicenseInfo() { //license info is retrieved var l = CurrentAppSimulator.LicenseInformation; if (l.IsActive) { // check if there is any trial version, and show appropriate message © Aptech Ltd Generating Revenue Apps/Session Code Snippet (Cont.): if (l.IsTrial) { await Dispatcher.RunAsync( Windows.UI.Core.CoreDispatcherPriority.Normal,() => { txtDetail.Text = “License status: Trial license”; var r = (l.ExpirationDate - DateTime.Now).Days; txtDetail.Text += System.Environment.NewLine + String.Format(“Remaining days: {1}”, l.ExpirationDate, r); }); } else //otherwise set message to full version { await Dispatcher.RunAsync( Windows.UI.Core.CoreDispatcherPriority.Normal, () => { txtDetail.Text = “License status: Full license”; txtDetail.Text += “no expiry”; }); }} else { © Aptech Ltd Generating Revenue Apps/Session Code Snippet (Cont.): await Dispatcher.RunAsync( Windows.UI.Core.CoreDispatcherPriority.Normal, () => { txtDetail.Text = “License status: license expired Purchase the app!”; }); } } When the code is executed, the output will be as shown in the following figure © Aptech Ltd Generating Revenue Apps/Session  In-app purchase means the ability of an app to allow sale or purchase of the app with the help of devices such as a mobile, tablet, or a PC  Many times such in-app purchase is allowed within games and other useful apps that allow the users to pay online and start using all the features of the app  The user can easily purchase such an app without any trouble The apps are normally activated immediately after in-app purchases  There is no need to download and update a fresh copy of the app that is already downloaded and is running on the systems  To develop an app with in-app purchase feature, the user has to create a config file that includes all the information about the app  This can be done by adding the code shown in Code Snippet to the appropriate config file © Aptech Ltd Generating Revenue Apps/Session Code Snippet: 00000000-0000-0000-0000-000000000000 http://apps.microsoft.com/webpdp/app/00000000-0000-0000-0000-000000000000 en-US 3 LicenseTest Will check the license info 10.00 $ USD © Aptech Ltd Generating Revenue Apps/Session Code Snippet (Cont.): License App 1.00 $ USD true true 2014-06-30T09:00:00.00Z true © Aptech Ltd Generating Revenue Apps/Session 10 When the user executes the code, the advertising banner will be displayed as shown in the following figure © Aptech Ltd Generating Revenue Apps/Session 19 Licensing an App - Licensing an app in Windows Store is made easy by Microsoft Most of the functionalities are in-built in the Store apps framework Create a blank new application and add code given in following Code Snippet to MainPage.xaml Code Snippet: { txtDetail.Text = “License status: Trial license.”;
