Try Out the SAP BTP SDK Wizard for Android

Please read Prerequisites first.

1. Open Android Studio.

2. Choose New SAP BTP Android App, which is an option created by the SAP BTP SDK Wizard for Android.

   

3. The wizard can save the server connection details for multiple servers. Fill in the required fields as shown below.

   Field	Value
   Account Name	SAP Mobile Services
   Admin API URL	See below for how to get this URL
   Admin UI URL	See below for how to get this URL
   Authentication Type	Basic
   Username	Username for your account
   Password	Password for your account
   Save Account Information	Check this so that you do not have to re-enter account information on subsequent runs of the wizard

4. Go to the SAP Mobile Services cockpit and under Important Links, both Admin URLs are present and can be copied.

   
   

5. Click Next on the Server Connection tab.

6. On the Cloud Configuration tab, select Sample and set the Application ID to be com.sap.wizapp.

   

7. SAP Mobile Services provides a sample back-end destination named com.sap.edm.sampleservice.v2 that is being used here to provide data for the application. It contains product categories, product, supplier, customer and sales order data. Select it and click Next.

   

8. On the Android Studio Project tab, provide the following configuration data.

   Field	Value
   Project Name	Wiz App
   Project Namespace	com.sap.wizapp
   Target Language	Java / Kotlin

   The screenshot below provides a Java example. Depending on which Target Language you choose, either Java or Kotlin code will be generated.

   

9. On the Project Features tab, provide the following configuration data.

   Field	Value
   Enable Multiple Users	uncheck
   Use Discovery Service as Configuration Provider	uncheck
   OData	Online
   Create a Sample User Experience for the Selected OData Destination	check
   Enable Logging	check
   Enable Upload	check
   Enable Usage Reporting	check
   Enable Crash Reporting	optional
   Enable Push	optional

   

10. If you would like to add push notification support to your app, proceed to Step 2, which describes how to acquire the google-services.json file required for push messaging. Otherwise, uncheck Enable Push, click Finish and proceed to Step 3.

If you check the Enable Push checkbox, an error message is displayed explaining that you need to specify a google-services.json file. We will obtain this file from the Cloud Messaging feature in Google Firebase.

1. Open the Firebase console and click Create project. (If you have created any before, click Add project.)

   

2. Click Continue until a new project is successfully created.

3. Access Project settings for the newly created project.

   

4. Scroll down and add Firebase to your app.

   

   The Android package name must match the Project Namespace you used to create the app in Android Studio. In our example, the Android package name is com.sap.wizapp.

   

5. Download the google-services.json file.

   

6. Now browse for the google-services.json file in the wizard. This file is placed into the app folder of the generated project and helps enable the app to work with Google Firebase notifications.

   

   You can add push configuration on the server as in the Send Notifications to Your Android Application tutorial.

7. Click Finish and proceed to Step 3.

1. Wait for the build to finish.

   

2. Choose an emulator for running the app.

   If you enabled push service, please make sure you install an emulator with Target labeled as Google Play. For more information on creating virtual devices that run in the Android Emulator, see Create and manage virtual devices in the Android Studio User Guide.

   

3. Click the Run toolbar icon.

   

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

   

4. Click Get Started and the license agreement screen is displayed.

   

   Read it and click Agree, you will see the Sign-In screen of the app. If you select Disagree, you will be asked to confirm whether to terminate onboarding. If you confirm, you will return to the Welcome screen. Otherwise, you can still select Agree to complete onboarding and start to use the app.

   

5. Log in with your username and password.

   

   The credentials you enter are securely stored by the app, and do not need to be re-entered the next time you open the app.

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

   

6. You can modify the passcode policy in the Mobile Service Cockpit under Client Configuration in Mobile Settings Exchange page. The passcode screen will not be displayed if the Enable Passcode Policy is not checked.

   
   

7. Because Enable Usage Reporting is checked, this screen can be used to show details of how the collected data will be used. For now, select either Allow or Deny. Usage Reporting is covered in a later tutorial in this mission.

   

8. Just like usage reporting, since Enable Crash Reporting is checked as well, this screen will be used to display details of how the collected information will be used. Select either Allow or Deny. If you select Deny, the crash information will only be stored locally.

   

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

   

   Tap Products to navigate to the products list.

   

10. Tap a list item to display the following editable detail screen.
