Note: Moments is currently unmaintained, and parts of the app may not work as intended.


Moments is a Snapchat clone built using Xamarin.Forms and Microsoft Azure.

Text messaging is out-of-style! Everyone these days sends selfies, pictures of their food, and emojis instead. Duh. Moments allows you to send those selfies and pictures of your food to those that love you. You can even draw funny pictures on them! That's not even the best part! Moments is completely open-source, so you can create your own SnapChat clone using Xamarin and Azure in just a few minutes.

But seriously. Moments is awesome! If you've ever wondered how to use custom renderers in Xamarin.Forms, upload blobs from your Xamarin apps using Azure Storage, or how to maximize shared code with Plugins for Xamarin, Moments can show you how.

If you think this is awesome, please share a link to this repository on Twitter, LinkedIn, whatever. It would be much appreciated! :)






Build Your Own

Moments uses Microsoft Azure for its back-end. To create host your own Moments app follow the instructions below to:

  • configure Azure Mobile Services,
  • configure Azure Storage,
  • setup Xamarin Insights, and
  • add the required constants to the Keys class in the app


1. Get the code

  1. Clone or download Moments using either the command line or GitHub for Windows/Mac client.

2. New Azure Mobile Service (for data)

  1. To power our backend, including our accounts and friends system, we will be using Azure Mobile Services. Create a new Azure Mobile Service - following these instructions - under New > Compute > Mobile Service > Create. Be sure to choose the BACKEND: Javascript option (do not choose the .NET backend).

3. New Azure Storage (for images)

  1. We have to store your selfies somewhere! Create a new Azure Storage account - following these instructions - under New > Data Services > Storage > Quick Create.
  2. Click on the Azure Storage account you just created and create a new container by clicking CONTAINERS from the top menu then ADD from the bottom. Name your container whatever you wish, but make sure to set Access: Public Blob.
  3. Click DASHBOARD from the top menu in the storage account then MANAGE ACCESS KEYS at the bottom. Take note of the "Storage Account Name" and "Primary Access Key" fields - they are required in the next step...

4. Connecting the Storage and Mobile Service

  1. Browse to the Azure Mbile Service created in step 2.1. and click CONFIGURE, then scroll down to the app settings section, and add two new key-value pairs:

    • STORAGE_ACCOUNT_NAME : value from previous step
    • STORAGE_ACCOUNT_ACCESS_KEY : value from previous step
  2. Press SAVE at the bottom to persist the changes.

5. Configuring the Service data backend

  1. Check to see if Git access is enabled by going the mobile service's DASHBOARD. If you look on the right-hand side, you should see something like "Setup source control" OR a "source control user" already showing (if you have already used source control with Azure, you may see "Reset your source control credentials"). Source control must be configured with Azure before you can continue; remember the credentials you create, they are not the same as your Azure login.
  2. Now go to the CONFIGURE tab for your Azure Mobile Service - you should see a Git URL. Copy this so that you can clone the repository on your Desktop (requries some familiarity with git). The basic steps are:
    • open Terminal or a command line prompt
    • cd Desktop (ie. navigate to the desktop or some other appropriate folder)
    • git clone YOUR_MOBILE_SERVICE_GIT_URL_HERE (will create a folder with the name of your service)
    • You'll be required to enter the Username and Password... this is not your Azure credentials, but the source control username and password you set-up previously.
    • when the cloning is complete, there will a folder with the same name as your Azure Mobile Service, containing another folder called service (with sub-folders like api, extensions, scheduler, shared, table).
  3. Delete the contents of repository (ie. the service folder) you just cloned and copy in the files from the Moments/Azure directory - ensure there is a service folder with all the other directories beneath it.
  4. Return to the command line Terminal
  • navigate to the folder containing the repository of your mobile service, eg cd YOUR_MOBILE_SERVICE_NAME
  • type git add . (the fullstop/point is important) This will allow Git to track all the new files in the directory
  • to commit the new files type git commit
  • type A for insert mode and then type a commit message
  • then press ESC follow by :x to exit the commenting mode if you are using a Mac
  • Type git push
  1. In the Azure Mobile Service go to DATA and then click CREATE at the bottom to add four tables (so repeat four times):
  • Account with all the permissions set to "Anybody with the Application Key"
  • User with "Anybody with the Application Key"
  • Friendship with "Only Authenticated Users"
  • Moment with "Only Authenticated Users"
  1. Go to the Azure Mobile Service DASHBOARD and click MANAGE KEYS at the bottom. Copy the Master Key for the next step.
  2. Return to the DATA section and click the Account table, then click SCRIPT and choose Insert from the drop-down list. Copy the Account_Insert.js code - replacing YOUR_MASTER_KEY_HERE with the value from the previous step. Refer to this blog for more info on how it works. Be sure to click SAVE at the bottom to persist changes to the script.

The backend for your Snapchat clone is now complete. :)

6. Xamarin Insights

  1. We want to track everything that happens within our app, so visit the Xamarin Insights portal, create a new application, and copy/paste the API key for Keys.cs in the next step.

7. Run the Xamarin App (iOS or Android)

  1. Open the solution for Moments and navigate to Helpers/Keys.cs. Paste in relevant keys and information as seen below: Keys.cs These values come from:
    • ApplicationURL - Azure Mobile Services DASHBOARD > MOBILE SERVICE URL
    • ApplicationMobileService - Azure Mobile Services DASHBOARD > MOBILE SERVICE URL
    • ApplicationKey - Azure Mobile Services DASHBOARD > MANAGE KEYS > APPLICATION KEY
    • ContainerURL - Azure Storage CONTAINERS page NAME column
    • ContainerName - Azure Storage CONTAINERS page URL column
    • InsightsKey - Xamarin Insights configuration (using this is optional)
  2. Build Moments for either an iOS or Android device, and watch it work its magic!

Special Thanks


Snapchat, built with Xamarin.Forms and Azure.
