Update your onActivityResult method like this

    //method for getting qr code from qr code after scan
            public void onActivityResult(int requestCode, int resultCode, Intent intent) {
                if (requestCode == 0) {
                    if (resultCode == RESULT_OK) {
                String contents = intent.getStringExtra("SCAN_RESULT");
Toast.makeText(this, contents , Toast.LENGTH_SHORT).show();     
    //start activity for scanning qr code
                Intent intent = new Intent("com.google.zxing.client.android.SCAN");
                intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
                startActivityForResult(intent, 0);

                        // Handle successful scan
                    } else if (resultCode == RESULT_CANCELED) {
                        // Handle cancel
                        Log.d("the result is","not ok");
                    }
                }
