Question

I have an phonegap application, and I need to trigger an event when a button is pressed on the device (not a button on the screen).

Is there a way to detect, say, volume change (in iPhone and maybe other devices too) ?

I use Phonegap, mgwt and gwt-phonegap.

Answer 1

You can get a simple event when such a button is pressed from gwt-phonegap.

Your code would look like this:

 phoneGap.getEvent().getVolumneUpButtonPressedHandler().addVolumneUpButtonPressedHandler(new VolumeUpButtonPressedHandler() {

  @Override
  public void onVolumeUpButtonPressed(VolumeUpButtonPressedEvent event) {
    // volume up button pressed

  }
});
