public void update(final Messsage msg) {
for(int i = 0; i < 50; ++i) {
if (msg.getDistanceToFace() > 40 && msg.getDistanceToFace() < 80) {
textView.setText("The number of occurrence is: " + i);
textView.setTextColor(Color.GREEN);
}
}
}

you should probably add a break after you set the text, the way you coded it will set a text for all the iteration of i but you will only see the last one (50)
