Click on Import and browse the location of your file and click Save.

Once import is complete, you will get a toast message “Application imported successfully”.

Go to your Android Studio and replace the URL with “ https://<the value you copied>/ ” in WelcomeActivity.java.

Uninstall the application you installed earlier and run the application again.

You will see that your app is pointing to Cloud Foundry environment now which means you successfully migrated your android application from Neo environment to Cloud Foundry environment with SAML configuration.

 

If the version of your SAP BTP SDK for Android is 3.2.0 or above, follow the steps given below:

  1. In your android project, go inside app -> res -> raw folder. Here, you will see sap_mobile_services.json file.
  2. Replace the service URL on line 9 with the host value you copied from defaultConfig.json file.

Now, uninstall the application you installed earlier and run the application.

 

You will see that your app is pointing to Cloud Foundry environment now which means you successfully migrated your android application from Neo environment to Cloud Foundry environment with SAML configuration.
