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();
});

}

/**
 * Finds contacts by name
 */

    ContactsService.getInstance().find(options,this::contactsFound,this::onError);
}

/**
 * Success callback
 */
void contactPicked(final Contact contact)
{
    System.out.println(contact);
}

/**
 * Success callback
 */
void contactsFound(final List<Contact> contacts)
{
    System.out.println(contacts);
}


/**
 * Error callback
 */
void onError(final MobileServiceError error)
{
    System.err.println(error.getMessage());
}

File system - Reading access to the file system of the mobile device.
Geolocation
Current position (lines of longitude and latitude as well as altitude)

Tracking the position by motion data (direction and speed)

/**
 * Use GeolocationService to acquire position information.
 * Results are delivered asynchronously via callbacks.
 */

/**
 * Lookup the current position of the device
 */
void getCurrentPosition()
{
    GeolocationService.getInstance().getCurrentPosition(this::positionFound,this::onError);
}

/**
 * Success callback
 */
void positionFound(final Position position)
{
    System.out.println(position);
}

/**
 * Error callback
 */
void onError(final MobileServiceError error)
{
    System.err.println(error.getMessage());
}

NFC - Option to read and write NFC tags

/**
 * Use NfcService to read and write NFC tags.
 * Results are delivered asynchronously via callbacks.
 */

/**
 * Start listener
 */
void startListening()
{
    NfcService.getInstance().startNdefListener(this::ndefListenerCallback,this::startNdefListenerSuccess,this::onError);
}

/**
 * Stop listener
 */
void stopListening()
{
    NfcService.getInstance().stopNdefListener(this::stopNdefListenerSuccess,this::onError);
}

/**
 * Tag read callback
 */
void ndefListenerCallback(final Ndef ndef)
{
    final Tag tag = ndef.getTag();
    System.out.println(tag);
}

/**
 * Listener successfully registered
 */
void startNdefListenerSuccess(final String message)
{
    System.out.println(message);
}

/**
 * Listener successfully removed
 */
void stopNdefListenerSuccess(final String message)
{
    System.out.println(message);
}

/**
 * Error callback
 */
void onError(final MobileServiceError error)
{
    System.err.println(error.getMessage());
}

Vibration

Simple vibration with variable duration, e.g. 1 sec.
Vibration patterns with variable duration and pauses, e.g. Vibration 0.5 sec, Pause 0.3 sec, Vibration 0.1 sec., etc.

/**
 * Vibrates one second
*/
VibrateService.getInstance().vibrate(1000);

/**
 * Pattern: Vibrate 500 ms, pause 250 ms, vibrate 250 ms (Android only)
*/
