    Building a App/Game for specific Windows Phone 8 device - To support >1GB or 512mb memory


    This week I was having a discussion with Jon Wetherall  from coolgamearcade.com. Jon is one of our Greenshoot teams and wanted to ask how they could target specific windows phone devices for their next title.

    So in respect of Windows Phone the two options of devices are

    · >1GB or higher RAM based devices

    · 512MB RAM (Low memory Windows Phone 8 devices)

    Building Specific optimized version for 1Gb & 512mb

    You actually have the ability within the Windows Store to build a app specifically tailored for each version Windows Phone and have them displayed in the Windows Phone Store under same app name.

    To achieve this you need to follow the guidance below

    1. Each Store release will need the same Product ID.

    a. To get the product id login to Windows Phone store http://dev.windowsphone.com

    b. Click on Dashboard

    c. Select the app and then click on details tab

    d. Scroll down to get App ID, copy this App ID

    e. Replace your product id in WMAppmanifest.xml simply open up your project solution in Visual Studio edit the WMAppManidest.xml and under the file under Packaging Tab replace the Product ID with the copied on from the dashboard.

    Once you have both the builds, add these two XAPs you need to submit each to the store for certification and publishing.

    The store certification team will test both the XAPs and app will be available on store.

    The advantage with this approach is that you can target both low end and 1GB RAM based devices with appropriate quality of graphics content. While the disadvantage is that you will have to maintain two builds.

    In this case your app customers will get the appropriate quality of graphics content based on their devices.

    Optimising your app/game for support on 512mb devices

    To get the maximum performance out of the 512MB RAM based device you can increase the peek memory usage cap from 150MB to 180MB by adding Functional Capability to the WMAppMainfest.xml file

    Add the following tag by editing WMAppManifest.xml in Visual Studio


    This increases the usage cap from 15mb to 180mb.


       1: <FunctionalCapabilities>
       3: <FunctionalCapability Name="ID_FUNCCAP_EXTEND_MEM"/>
       5: </FunctionalCapabilities>

    You can refer to How to modify the app manifest file for Windows Phone 8 for further information.

    Supporting only 1GB devices

    If your game is pretty intensive on memory you can choose to simply target  >1G devices (remember this will limit your downloads as your targeting a specific set of devices which are generally premium in terms of costs to consumers)

    2. To build app targeting only 1GB RAM based device, you will need to opt out low memory device

    This can be achieved by forcing memory cap requirements in WMAppManifest.xml

    Add the following tag by editing WMAppManifest.xml in Visual Studio


    This completely opts out of availability for lower-memory phones.

    The app won’t appear in the Windows Phone Store for lower-memory phones and it can’t be installed on lower-memory phones.


       1: <App>
       5:   <Requirements>
       7: <Requirement Name="ID_REQ_MEMORY_300" />
       9:   </Requirements>
      11: </App>

    You can refer to How to modify the app manifest file for Windows Phone 8 for further information.

    You can now publish the complied  .XAP file to the Windows Phone Store. When users visit the store and search for your game or app it will not be visible to consumers with low memory 512MB RAM based devices.

    Project Siena Beta 3 building an app without programming skills


    Beta3 release of Project Siena. This new release makes it even easier for business experts, business analysts and other app imagineers to create powerful custom mobile apps that are connected to enterprise services, major SaaS, and popular web and social services.

    Siena Beta 3

    The Beta3 release is a major addition to Project Siena’s empowerment of business experts and analysts. Key new functionality includes:

    • One-click read/write connection to Yammer, Facebook, Twitter, Instagram, YouTube, Coursera, Bing Search, and Bing Translate.
    • Connections to more types of RESTful services with OAuth 1 and OAuth 2 support.
    • A WADL accelerator for the ecosystem to rapidly create connections to RESTful services – this will be released over the next four weeks.
    • Write back to SharePoint lists.
    • Data visualization through interactive charts.
    • International languages support throughout the UI and in formulas and functions – this will be released over the next four weeks.
    • Across the board improvements, including more control over interactivity and design.

    In Beta2, we introduced the concept, illustrated below, that non-programmers could consume services as easily as using an Excel function. And composing multiple services was just like linking two Excel functions.

    Beta3 takes the ability to work with services to another level, where getting started with key services is now as easy as adding a PowerPoint slide layout to a deck. 

    Please install the latest release of Project Siena from the Windows Store, check out http://microsoft.com/ProjectSiena , watch a tutorial video, download a sample app for inspiration, and then bring your own ideas to life in a Siena

    Cross Platform Mobile Development with Visual Studio


    One of the key goals for today’s developers is how to build an app or game and get it on as many platforms in the short most cost effective way.

    However building rich applications targeting multiple mobile platforms and a variety of devices up to now hasn't been an easy task but with In case you haven’t heard yet, the final release of Visual Studio 2013 Update 2 is also now available.

    This update brings many new features, including tools for Windows Phone 8.1 and universal Windows apps.

    We now make it easier for developers to undertake a multi-device development in a mobile-first world with the technology of their choice – whether .NET, C++ or JavaScript.

    Visual Studio+ Xamarin

    Microsoft’s partnership with Xamarin has enabled C# and Visual Studio developers to target additional mobile devices including iOS and Android. Developers using Xamarin and Visual Studio can create native apps taking advantage of the underlying device, with great productivity of C#, and sharing code and libraries between their iOS, Android and Windows applications.

    Visual Studio + Apache Cordova

    Apache Cordova is a popular open source platform. It is a set of device APIs that allow a mobile app developer to access native device function such as the camera or accelerometer from JavaScript. Combined with a UI framework such as jQuery Mobile or Dojo Mobile or Sencha Touch, this allows a smartphone app to be developed with just HTML, CSS, and JavaScript.


    The Visual Studio team has recently announced its tooling support for Apache Cordova. What possibilities does it give? Now developers can use Visual Studio to easily build hybrid apps that run on iOS, Android, Windows and Windows Phone using a single project based on HTML and JavaScript. Click here for more information.

    Why use Apache Cordova and Visual Studio

    1.Developers can use their existing skills in HTML and JavaScript to create hybrid packaged apps for multiple devices while taking advantage of each device’s capabilities.

    2. These tools support end-to-end development of cross-platform mobile applications targeting Android, iOS, Windows and Windows Phone using Visual Studio.

    3. Project templates are available for both JavaScript and TypeScript, and provide a standard blank Cordova starter project. Developers can pick their HTML/JavaScript framework of choice, whether Backbone and jQuery UI, or Angular.js and Bootstrap, or WinJS.

    4. Projects can be built, deployed, and debugged against a variety of devices, device emulators and web-based mobile simulators. By default, you can use the Apache Ripple Simulator to test your app on a number of emulators.     


    5. By installing and configuring the vsmda—remote npm package on a Mac, you can even build for iOS, deploy to a device via iTunes, or start your app in the iOS Simulator on a Mac right from Visual Studio.

    See here how to get started for free

    If you would like to get started with Cordova for Windows devices, you can refer to the Cordova documentation, or see here what you will need if you are working on a Mac, if you want to develop for Windows Phone 8, or for Windows 8.
