Android Question Head Phone Jack push detection

[ocalle]

Hello, I continue finding a solution to headphone jack click detection, attached is a code of some dude in stackoverflow that found a solution that detect when the jack button is pressed and the delay that remain on it.

Spoiler: Getdowntime()

audioSession = new MediaSession(getApplicationContext(), "TAG");
audioSession.setCallback(new MediaSession.Callback() {

@override
public boolean onMediaButtonEvent(final Intent mediaButtonIntent) {
String intentAction = mediaButtonIntent.getAction();
if (Intent.ACTION_MEDIA_BUTTON.equals(intentAction)) {
KeyEvent event = mediaButtonIntent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);

if (event != null) {

stopTimeOfGame_millis = event.getDownTime();
double usersReactionTime = (event.getDownTime() - startTimeOfGame_millis) / 1000.0;
UtilsRG.info("event.getDownTime(): " + usersReactionTime);


double getEventTime = (event.getEventTime() - startTimeOfGame_millis) / 1000.0;
UtilsRG.info("event.getEventTime(): " + getEventTime);

int action = event.getAction();
if (action == KeyEvent.ACTION_DOWN) {
long action_down = android.os.SystemClock.uptimeMillis();
double actionDown = (action_down - startTimeOfGame_millis) / 1000.0;
UtilsRG.info("ACTION_DOWN: " + actionDown);
}

if (action == KeyEvent.ACTION_UP) {
long action_up = android.os.SystemClock.uptimeMillis();
double actionUp = (action_up - startTimeOfGame_millis) / 1000.0;
UtilsRG.info("ACTION_UP: " + actionUp);
}
}
}
return true;
}


});

PlaybackState state = new PlaybackState.Builder()
.setActions(PlaybackState.ACTION_PLAY_PAUSE)
.setState(PlaybackState.STATE_PLAYING, 0, 0, 0)
.build();
audioSession.setPlaybackState(state);

audioSession.setFlags(MediaSession.FLAG_HANDLES_MEDIA_BUTTONS | MediaSession.FLAG_HANDLES_TRANSPORT_CONTROLS);

audioSession.setActive(true);

The results on log was

got following log:

event.getDownTime(): 0.281

event.getEventTime(): 0.421

ACTION_DOWN: 0.47

ACTION_UP: 0.471

Thus now I got the moment when the user presses the key down.



I dont know how translate this to B4a to check if it work.
