问是否可以在onCreate()完成之前调用SaveInstanceState？

EN

private LaunchedFrom launchedFrom = null; 

protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  // some members initialization

  if (savedInstanceState == null) {
    Intent intent = getIntent();
    launchedFrom = handleIntentAction(intent);
  } else {
    // Restoring saved state.
  launchedFrom = LaunchedFrom.fromEvent(savedInstanceState.getString(BundleParams.KEY_LAUNCHED_FROM));
  }
}

protected void onSaveInstanceState(Bundle outState) {
  super.onSaveInstanceState(outState);
  outState.putString(BundleParams.KEY_LAUNCHED_FROM, launchedFrom.getEvent());
}

private LaunchedFrom handleIntentAction(Intent intent) {
  LaunchedFrom launchedFrom = LaunchedFrom.MAIN;
  if (intent != null) {
    // some logic to override launchedFrom
  }
  return launchedFrom;
}
