这是 appData 类:

private AppData appData;

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main_layout);
  String name = null;
  if (savedInstanceState == null) {
    Bundle extras = getIntent().getExtras();
    if (extras != null) {
      //String x = extras.getString("companyData");  //this works...
      appData.dbData = extras.getString("companyData");  //this crashes!  
      ...
      ...

为什么不允许分配?
