XDEV Mobile Kit

The XDEV Mobile Kit allows you to access mobile devices from a server application developed with RapidClipse as well as the final deployment of hybrid apps.

  • Tools - Allow you to deploy hybrid mobile apps and transfer them directly to mobile devices.
  • API - Grants access to hardware and system functions of mobile devices via Vaadin.

Supported services

  • Device buttons - App service

    /**
     * Add a button handler, e.g. for the back button
     */
    AppService.getInstance().addBackButtonHandler(event->{
        // Do something ...
        // and consume event so that it will not be processed in the default manner by the source which originated it.    
        event.consume();
    });
