Android studio - Broadcast receiver... how to dump the input?

Question

I have an android studio app on a zebra device with inbuilt barcode scanner. Using broadcast receiver, I am successfully intercepting and using the scanned input.

However - I cant find a way of 'dumping' the input after interception... it just seems to have to go somewhere, either into any text field it can find which might have focus, or if a button, for example , has focus, it flickers each time a character is received.

I suspect there is a way of erasing the input after interception, but I cant find it.

Has anyone had the same issue?

The code I am using is very simple but seems to work:

private final BroadcastReceiver receiver = new BroadcastReceiver() {
     @Override
    public void onReceive(Context context, Intent intent) {
        String code = intent.getStringExtra(DATA);
         if (scantype.contains("LASER")) {
            try {
                process_code(code);
            } catch (JSONException e) {
                e.printStackTrace();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }

    }
};
