I'm following the beginner tutorial and I've applied the "Enable Offline OData in Your Android Application" step to my Customers.

If you enter the application and click fast on Customer (at the very start) it gets you this error:

with the following stack trace:

E/com.sap.wizapp.data.operation.AbstractOnODataOperations: [main] SAPServiceManager was not initialized
E/com.sap.wizapp.app.ErrorPresenterByNotification: [SAPWizardErrorHandler] Download failed: Download operation failed, please try to restart the application.java.lang.IllegalStateException: SAPServiceManager was not initialized
