Fixed version (ground truth):

  doneButton.setOnClickListener(new View.OnClickListener(){
    @Override public void onClick(    View v){
      if (passphraseEditText.getText().toString().equals("String_Node_Str")) {

        builder.setTitle(R.string.alert_no_passphrase_title).setMessage(R.string.alert_no_passphrase_message);
        builder.setPositiveButton(R.string.ok,null);
        builder.create().show();
        return;
      }
 else {
        if (!passphraseEditText.getText().toString().equals(passphraseConfirmationEditText.getText().toString())) {
          AlertDialog.Builder builder=new AlertDialog.Builder(getActivity());
          builder.setTitle(R.string.alert_no_passphrase_match_title).setMessage(R.string.alert_no_passphrase_match_message);
          builder.setPositiveButton(R.string.ok,null);
          builder.create().show();
          return;
        }
      }
      Passphrase masterPassphrase=PassphraseFactory.getPassphraseInstance(selectedPassphrasetype,passphraseEditText.getText().toString(),passphraseEditText.getText().toString(),null);
      Passphrase.setMasterPassword(masterPassphrase,getActivity());
      getActivity().startService(BaseService.getServiceIntent(getActivity(),null,BaseService.ACTION_DETECT_ENVIRONMENT));
      mMasterPasswordSetListener.onMasterPasswordSet();
