Try Out the SAP BTP SDK Wizard for Android

Please read Prerequisites first.

1. Open Android Studio.

2. Choose New SAP BTP Android App

   

3. The wizard can save 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 in the Server Connection screen.

6. Select Sample in the Cloud Configuration screen and set the Application ID to btp.sdk.wizapp.

   

7. SAP Mobile Services provides a sample back-end destination called com.sap.edm.sampleservice.v4, which is used here to provide data for the application. It includes product categories, products, suppliers, customers and sales order data. Select it and click Next.

   

8. Provide the following configuration data in the Android Studio Project screen.

   Field	Value
   Project Name	Wiz App
   Project Namespace	com.sap.wizapp
   UI Framework	View-based UI / Jetpack Compose-based UI

   

9. Provide the following configuration data in the Project Features screen.

   Field	Value
   Enable Multiple Users	uncheck
   Activation Options	Generate AppConfig.json
   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 cloud messaging. Otherwise, uncheck Enable Push, click Finish and proceed to Step 3.

If you check the Enable Push checkbox, an error message will appear, indicating 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. Navigate to the Project settings for the newly created project.

   

4. Scroll down and add a 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 located in the generated project’s app folder, enabling 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 Create and proceed to Step 3.

1. Wait for the build to finish.

   

   You may encounter a build error similar to: “Could not resolve all files for configuration ‘:classpath’……”, open Preferences (Windows: Settings, Mac: Android Studio > Settings…) to change gradle jdk to 17.

   

   Finally, sync the project with the gradle files.

   

2. Choose an emulator for running the app.

   If you enabled the push service, please ensure you install an emulator with the 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 displayed the first time the app is launched.

   

4. Check the agreement, click Get Started, and the sign-in screen is displayed. 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.

   

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

   

   

6. Enable Usage Reporting is checked, this screen can display details about how the collected data will be utilized. For now, select either Allow or Deny. Usage Reporting is covered in another tutorial in this mission.

   

7. Similar to Usage Reporting, if Enable Crash Reporting is checked, this screen will show details about how the collected information will be used. Choose either Allow or Deny. If you select Deny, the crash information will only be stored locally.

   

8. Click Next on the Allow Notifications screen to choose either Allow or Don’t allow to indicate whether you want the app to send you notifications.

9. The first screen of the app displays various entities that are available 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.
