Any idea what I am doing wrong?
知道我做错了什么吗？
回答by Bill Phillips
The crash is because the binder you're getting back is an instance of BinderProxy, not your local binder class. This usually happens because your activity is attempting to bind to a service that is not in the same process. When binding across process boundaries, an instance of BinderProxy is used instead of the actual instance (since that's in a different process).
崩溃是因为您返回的活页夹是 BinderProxy 的一个实例，而不是您本地的活页夹类。这通常是因为您的活动试图绑定到不在同一进程中的服务。当跨进程边界绑定时，使用 BinderProxy 的实例而不是实际实例（因为它在不同的进程中）。
