On this machine, the SAP Cloud Platform SDK for Android has been installed and configured to make use of an instance of a SAP Cloud Platform Mobile Services trial account with an application configuration that has push notifications enabled.

All set, let’s begin!

Step 2: Create and run the project

Open Android Studio.
Android Studio

Step 3: Explore the app

The welcome screen is shown the first time the app is run.
Welcome screen

Sign in with the following credentials:

  • User Name: p2000464045
  • Password: SCP!2pwd
Authentication screen

The credentials are used to authenticate against the SAP Cloud Platform Identity Service, are securely stored by the app, and do not need to be re-entered. Take note of the time that the authentication occurred. This will be helpful to know to identify the correct registration in the Send a notification step.

The passcode (or fingerprint if enabled) screen provides an additional layer of security for your app.
Passcode screen

The first screen of the app shows the different entities that are in the sample OData service.
Entities screen

Click on ProductCategories to reach the below list screen.
Categories screen

Click on a list item to show an editable detail screen.
Category detail

Step 4: Examine the customer's screen

Return to the entity list screen (first screen of the app) by pressing the back button twice.
Back from detail screen

Back from list screen

Click the Customers entity.
Entities screen

Notice that it displays the city rather than the customer name and address. This is because the app was generated from the OData service metadata, which does not indicate which of the many fields from the customer entity to display.
Customers Screen

Each customer is displayed in an Object Cell, which is one of the Fiori UI for Android controls.
Object Cell

As seen above, an Object Cell can display more than one field. In the next section, the app will be modified to make use of the image, the labels (headline, sub-headline), and the attributes (status) fields. A separator decoration will be added between rows, and the customers will be shown in alphabetical order.

Step 5: Add first name, last name, address, image

In Android Studio:

  1. Press Control+N and enter ItemListActivity to open the file.
    Find ItemListActivity
  2. Press Control+F12 and enter onBindViewHolder to move to the onBindViewHolder method.
    Find onBindViewHolder
  3. Find the fourth line of code.

  4. Replace it with the code below.

    if (eValue instanceof CustomersUIConnector && mProp.equals("City")) {
        String name = eValue.getPropertiesWithValues().get("FirstName")+ " "
                + eValue.getPropertiesWithValues().get("LastName");
        String address = eValue.getPropertiesWithValues().get("HouseNumber") + " " +
                eValue.getPropertiesWithValues().get("Street") + " " +
        String country = eValue.getPropertiesWithValues().get("Country");
        Drawable drawable = ContextCompat.getDrawable(getApplicationContext(),
        holder.mContentView.setStatus(country, 1);
    else {
  5. Notice that two of the classes, CustomersUIConnector and Drawable cannot be resolved and are shown in red.
    Select each class and press Alt+Enter to make use of Android Studio quick fix to add the missing imports.

Step 6: Add a divider
  1. Press Ctrl+F12 and enter setupRecyclerView to move to the setupRecyclerView method.
  2. Add the below lines.
    LinearLayoutManager llm = new LinearLayoutManager(this);
    recyclerView.addItemDecoration(new DividerItemDecoration(ctx, llm.getOrientation()));
  3. Notice that two of the classes, LinearLayoutManager and DividerItemDecoration cannot be resolved. Select each class and press Alt+Enter to make use of Android Studio quick fix to add the missing imports.
Step 7: Sort by last name
  1. Press Cntl+N and enter DownloadOperation to open the file.
  2. Press Ctrl+F and search for getCustomers.
  3. Replace the line (73) containing the getCustomers method call with the below code.
    DataQuery query = new DataQuery().orderBy(Customer.lastName);
    List<> customers =
Step 8: Run the modified app

Click the Run toolbar icon to run the app and try out the changes.

  2. Under Mobile Applications, select Wiz App.
    Management cockpit
  3. Select the registration to send the notification to.
    Send notification
  4. Specify the notification text to send to the app.
    Send notification
Step 10: Receive the notification in the app

Notice that the app shows the notification.
Receive notification

Step 11: Receive notification in device notification drawer

On the emulator, open another app, such as Chrome, which will cause the Wiz App to no longer be the foreground app.

Send another notification.

Notice that since the app is in the background or not running, a notification is placed in the notification drawer.

Receive Notification Background

Clicking on the notification will bring the app to the foreground or open the app. Custom logic could be added to the app to decide on the action to take, such as displaying the new Office Furniture category.

Step 12: Bonus

Congratulations! You have now completed the SAP Cloud Platform SDK for Android tutorial.

Send one more notification with a short description of an app you might consider making with the SDK and show it to an SAP staff member for some cool swag.
