            ----
}

@OverrideprotectedvoidonActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);

    if (requestCode == 0) {
              if (resultCode == RESULT_OK) {
                 Stringcontents= intent.getStringExtra("SCAN_RESULT");
                 Stringformat= intent.getStringExtra("SCAN_RESULT_FORMAT");
                 // Handle successful scanEditTextpassphrase= (EditText) findViewById(R.id.txtPassphrase);
                 passphrase.setText(contents);
              } elseif (resultCode == RESULT_CANCELED) {
                 // Handle cancel
              }
           }

}
