Enable Push Notifications in the MDK Public Store Client

1. Open the SAP Cloud Platform Mobile Services cockpit, click Mobile Push Notification feature.

   

   You can add Mobile Push Notification feature by clicking on + icon in case feature is not already assigned to the application.

2. Select SAP Mobile Services Client under Predefined for option, click Save.

   

   Predefined push is supported only for the MDK (SAP Mobile Services client) public store client.

   If you want to enable push notification in your custom MDK client then follow this tutorial.

1. Launch the Dev space in SAP Business Application Studio.

2. Navigate to File menu → click New Project from Template.

   

3. Select MDK Project and click Next.

   

4. In Basic Information step, select or provide the below information and click Next:

   Field	Value
   MDK template type	Select Empty from the dropdown
   Your project name	MDK_Push
   Your application name	<default name is same as project name, you can provide any name of your choice>

   

   More details on MDK template is available in help documentation.

   If you see Cloud foundry token expired, continue without mobile services connection? message, then set the Cloud Foundry environment again by clicking at bottom left corner of your status bar to initiate a valid session and repeat above steps.

5. After clicking Next, the wizard will generate your MDK Application based on your selections. You should now see the MDK_Push project in the project explorer. As you have already opened the workspace, there is no need to open the generated project in a new workspace. Ignore the pop-up or click the cross icon to hide the window.

   

In this step, you will create the following actions:

• Push Notification Register action: this will register the device with SAP Cloud Platform Mobile Services for push notification.

• Message actions: these will display a message if Push Notification Register action has succeeded or failed.

1. Create a Push Notification Register action.

   Right-click the Actions folder | MDK: New Action | choose MDK Other Actions in Category | click Push Notification Register Action | Next.

   

   Provide the below information:

   Property	Value
   Action Name	PushRegister

   

   More details on Push Notification Action is available in help documentation.

   Click Next and then Finish on the confirmation step.

2. Define a success message if the Push Register Notification action is succeeded.

   Right-click the Actions folder | MDK: New Action | choose MDK Message Actions in Category | click Message Action | Next.

   

   Provide the below information:

   Property	Value
   Action Name	PushRegisterSuccessMessage
   Type	Select Message from the dropdown
   Message	Push Notification registered
   Title	Success
   OKCaption	OK
   OnOK	--None--
   CancelCaption	leave it blank
   OnCancel	--None--

   

   Click Next and then Finish on the confirmation step.

3. Define a failure message if the Push Register Notification action is failed.

   Right-click the Actions folder | MDK: New Action | choose MDK Message Actions in Category | click Message Action | Next.

   

   Provide the below information:

   Property	Value
   Action Name	PushRegisterFailureMessage
   Type	Select Message from the dropdown
   Message	Push Notification didn't register
   Title	Failure
   OKCaption	OK
   OnOK	--None--
   CancelCaption	leave it blank
   OnCancel	--None--

   

   Click Next and then Finish on the confirmation step.

4. Define Success and Failure actions for PushRegister.action.

   In the action editor for the new action, expand the Common Action Properties and provide the below information:

   Property	Value
   Success Action	Select PushRegisterSuccessMessage.action from the dropdown
   Failure Action	Select PushRegisterFailureMessage.action from the dropdown

   When PushRegister.action gets executed successfully then PushRegisterSuccessMessage.action will be triggered or if PushRegister.action fails then PushRegisterFailureMessage.action will be triggered.

   

In the step, you will set and call the Push Register Notification action when app is updated with the new metadata.

It is up to developers how they want to call a Push Register Notification action.

Double-click Application.app file, select the PushRegister.action for the OnDidUpdate event.

So far, you have learned how to build an MDK application in the SAP Business Application Studio editor. Now, we deploy this application definition to Mobile Services.
