Question

当我通过登录活动登录并导航到MainActivity时，我的应用程序崩溃了。 MainActivity在OnCreate方法上有一个ObjectBox Box对象引用。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //ObjectBox Box object reference for the BookEntity class 
    BoxStore boxStore = ((App) getApplication()).getBoxStore();
    bookBox = boxStore.boxFor(BookEntitiy.class);

    //bind views using butterknife
    ButterKnife.bind(this);

    //reference the BookViewModel ViewModel
    viewModel = ViewModelProviders.of(this).get(BookViewModel.class);

    //call method
    observeViewModel();
}

当我删除或评论Box对象参考代码时，应用程序会正确导航到MainActivity.java活动而不会崩溃。

导致这种情况的原因是什么？

我完成了这个问题。网站上的ObjectBox的数据库设置和配置不是很清楚，一步一步。我必须在Udemy上阅读Objectbox的视频教程才能正确设置。请创建关于正确设置ObjectBox的清晰教程/文档，尤其是使用gradle文件和manifest.xml等。谢谢。

使用ObjectBox Box对象
