Android Studio - 如何调试这种情况？

Question

前言

我正在维护我从另一个团队继承的应用程序

场景

我理解 ClassCastException 但我一直找不到代码中出现此错误的位置。

（我不确定为什么此时输出截止）

NormalViewHolder.java

第 27 行

public class NormalViewHolder extends ComponentViewHolder<NormalViewModel> {

第 55-64 行

public NormalViewHolder(final View itemView, final RecyclerView.RecycledViewPool relatedItemsViewPool) {
    super(itemView);
    Dagger.getInstance(itemView.getContext()).inject(this);
    ButterKnife.bind(this, itemView);

    adapter = new NormalRelatedItemsAdapter();
    recyclerView.setRecycledViewPool(relatedItemsViewPool);
    recyclerView.setAdapter(adapter);
    recyclerView.setNestedScrollingEnabled(false);
}

问题

即使使用下面屏幕截图中的设置，该应用程序也会突然停止。我已经在 bind 和 onBindViewHolder 周围设置了断点，并一直跟踪它们，但无济于事。我该如何着手追踪这个问题？我在想我可以在断点处四处移动以将东西放在一起，但我没有任何运气..建议？

额外

在研究这个问题时，我将我的断点设置调整为以下但没有成功：

Answer 1

这是无法调试的情况。

此应用是为利用 Dagger 模块而编写的。在应用程序中有一行引用了不兼容的 class 但在堆栈跟踪中甚至从未提及的文件中 - 使我的调试方法变得毫无用处。

最终我不得不逐行检查，手动检查每一种情况。很好的老式肘部润滑脂。
