Opposite Operator

[FMCalisto]

Use opposite operator instead of the logic complement operator.

376         }
377         // If not, then display error dialog
378         else {
379             final boolean exit = !(errorCode == WebViewClient.ERROR_HOST_LOOKUP);
380             me.runOnUiThread(new Runnable() {
381                 public void run() {

Why is this an issue?

Use opposite operator instead of negating the whole expression with a logic complement operator. It makes code easier to read and understand.

Ex:

public boolean bar(int a, int b) {

  if (!(a == b)) { // use !=
    return false;
  }

  if (!(a < b)) { // use >=
    return false;
  }

  return true;
}
