Fixed version (ground truth):

  }

  }
  if (mCandidateView != null && mCandidateView.dismissAddToDictionaryHint()) {
    postUpdateSuggestions();
  }
  boolean pickedDefault=false;
  InputConnection ic=getCurrentInputConnection();
  if (ic != null) {
    ic.beginBatchEdit();
    abortCorrection(false);
  }
  if (mPredicting) {
    if (mAutoCorrectOn && primaryCode != '\'' && (mJustRevertedSeparator == null || mJustRevertedSeparator.length() == 0 || mJustRevertedSeparator.charAt(0) != primaryCode)) {
      pickedDefault=pickDefaultSuggestion();
      if (primaryCode == KEYCODE_SPACE) {
        mJustAddedAutoSpace=true;
      }
    }
 else {
      commitTyped(ic);
    }
  }

    removeTrailingSpace();
    mJustAddedAutoSpace=false;
