I'm creating an alert dialog using AlertDialog.Builder from onClick callback for a button
AlertDialog.Builder builder = new AlertDialog.Builder(activity);
builder.setCancelable(false);
builder.setNegativeButton(R.string.cancel, (dialog, which) -> isReporting = false);
builder.show();
99.9% of the time everything works fine, but recently I started seeing some crash reports like this:
Fatal Exception: android.view.WindowManager$BadTokenException: Unable to add window -- window android.view.ViewRootImpl$W@db362a2 has already been added

exception indicates I'm trying to re-add alert that already shown, but it's not the case. why this happens?
