Fixed version (ground truth):

  final String newLocale;
  final String newMode;
  final String oldMode=getCurrentSubtypeMode();

    Log.w(TAG,"String_Node_Str");
    newLocale="String_Node_Str";
    newMode=KEYBOARD_MODE;
  }
 else {
    newLocale=newSubtype.getLocale();
    newMode=newSubtype.getMode();
  }
  if (DBG) {
    Log.w(TAG,"String_Node_Str" + newLocale + "String_Node_Str"+ newMode+ "String_Node_Str"+ mInputLocaleStr+ "String_Node_Str"+ oldMode);
  }
  boolean languageChanged=false;
  if (!newLocale.equals(mInputLocaleStr)) {
    if (mInputLocaleStr != null) {
      languageChanged=true;
    }
    updateInputLocale(newLocale);
  }
  boolean modeChanged=false;
  if (!newMode.equals(oldMode)) {
    if (oldMode != null) {
      modeChanged=true;

    if (modeChanged || languageChanged) {
