NOTE: Microsoft Azure recommends Azure App Service Mobile Apps for all new mobile backend deployments.
NOTE: We will create new mobile service project by using Azure classic portal. By using Visual Studio 2013 Update 2, we can also add a new mobile service project to existing Visual Studio solution.
We need Azure account.
Create new mobile service
Follow these steps to create new mobile service.
1) Log into http://manage.windowsazure.com . At bottom of navigation pane, click +NEW. Expand Compute and Mobile Service, then click Create.
This displays Create a Mobile Service dialog.
2) In Create a Mobile Service page, select Create a free 20 MB SQL Database, select .NET runtime, then type subdomain name for new mobile service in URL textbox. Click right arrow button to go to next page.
This displays Specify database settings page.
NOTE: We create new SQL Database instance and server. We can reuse this new database and administer it as we would any other SQL Database instance. If we already have database in same region as new mobile service, we can instead choose Use existing Database and then select that database. Use of a database in different region is not recommended because of additional bandwidth costs and higher latencies.
3) In Name, type name of new database, then type Login name, which is administrator login name for new SQL Database server, type and confirm password and click check button to complete process.
You have now created new mobile service that can be used by our mobile apps.
Create new Xamarin Android app
Once we have created our mobile service, we can follow an easy quickstart in Azure classic portal to either create new app or modify existing app to connect to our mobile service.
We will download new Xamarin Android app and service project for our mobile service.
1) In , click Mobile Services and then click mobile service that we just created.
2) In quickstart tab, click Xamarin under Choose platform and expand Create a new Xamarin app.
This displays three easy steps to create Xamarin Android app connected to our mobile service.
3) If we haven't already done so, download and install Visual Studio Professional 2013 on our local computer or virtual machine.
4) If we haven't already done so, download and install Xamarin Studio or Xamarin for Visual Studio.
5) Under Download and publish your service to the cloud, select Android and click Download.
This downloads solution contains projects for both mobile service and for sample To do list application that is connected to our mobile service. Save compressed project file to our local computer and make note of where we save it.
6) Download our publish profile, save downloaded file to our local computer and make note of where we save it.
Test mobile service
Mobile service project lets us run our new mobile service locally. This makes it easy to debug our service code before we even publish it to Azure.
1) On our Windows PC, download our personalized server project, extract it and then open it in Visual Studio.
2) Press F5 key to rebuild project and start mobile service locally. Web page is displayed after mobile service starts successfully.
Publish our mobile service
1) In Visual Studio, right-click project, click Publish >> Microsoft Azure Mobile Services. Instead of using Visual Studio, we may also use Git.
2) Sign in with Azure credentials and select our service from Existing Mobile Services. Visual Studio downloads our publish settings directly from Azure. Finally, click Publish.
Run Xamarin Android app
Final stage is to build and run our new app.
1) Navigate to client project within mobile service solution, in either Visual Studio or Xamarin Studio.
2) Press Run button to build project and start app. We will be asked to select emulator or connected USB device.
NOTE: To be able to run the Android emulator, we must define least one Android Virtual Device. Use the AVD Manager to create and manage these devices.
3) In app, type meaningful text, such as Complete the tutorial and then click plus icon.
This sends POST request to new mobile service hosted in Azure. Data from request is inserted into TodoItem table. Items stored in table are returned by mobile service and data is displayed in list.
NOTE: We can review code that access our mobile service to query and insert data, which is found in ToDoActivity.cs c# file.
