Get the ID of an android touch that has just ended?

Processing for Android
1

I’m making an android app with multi touch and when a finger leaves the screen, I’d like to know which one it was because I’m tracking how long it has been since each started.

Can I do something like this:

void touchEnded(Touch t)
{
  print(t.id);
}

Anybody know?

Thanks

Try and see if this code can help.

float[] old_x_touches;
float[] old_y_touches;
int tl;
boolean allow = true;

void setup() {
  fullScreen();
  orientation(PORTRAIT);
  textFont(createFont("SansSerif", 24 * displayDensity));
  textAlign(CENTER, CENTER);
}    

void draw() {
  if (allow) {
    background(255);
    for (int i = 0; i < touches.length; i++) {
      float d = (100 + 100 * touches[i].area) * displayDensity;
      fill(0, 255 * touches[i].pressure);
      ellipse(touches[i].x, touches[i].y, d, d);
      fill(255, 0, 0);
      text(touches[i].id, touches[i].x + d/2, touches[i].y - d/2);
    }
    old_x_touches = new float[touches.length];
    old_y_touches = new float[touches.length];
    for (int i = 0; i < touches.length; i++) {
      old_x_touches[i] = touches[i].x;
      old_y_touches[i] = touches[i].y;
      tl = touches.length;
    }
    for (int i = 0; i < touches.length; i++) {
      text("Touch "+i+" is "+floor(touches[i].x)+" , "+ floor(touches[i].y), width/2, 50+i*50);
    }
  }
}

void mouseDragged() {
  if (allow) {
    background(255);
    allow = false;
    for (int i = 0; i < tl; i++) {
      text("Last saved touches are "+floor(old_x_touches[i])+" , "+ floor( old_y_touches[i]), width/2, 50+i*50);
    }
  }
}
