What do you mean by stop `Runnable`? You know what a `Runnable` is ? – ADM May 02 '18 at 18:08

@ADM yeah.. Because it is going to run non stop even if i scan a QR code. I want it to go to anther activity when I scan a QR code and it stops. – Kopi Bryant May 02 '18 at 18:14

Whats going to run ? `textResult.post()` this code ? This is not going to run non stop. Are you asking about stop the `Vibrator`? – ADM May 02 '18 at 18:15

You need to release BarcodeDetector after scanning complete. As
barcodeDetector.release();
