我找到了解决办法。

正如 RemoteCallbackList 文档，如果注册的回调的过程中消失了，这个类会照顾从列表中自动删除它。如果你想要做更多的工作，在这种情况下，你可以创建一个实现onCallbackDied（E）方法的子类。

所以，我创建了一个子类 RemoteCallbackList 接口 IRemoteCallbackDied ：

So, i created a subclass for RemoteCallbackList and interface IRemoteCallbackDied:

   private interface IRemoteCallbackDied<E extends IInterface> {
      public void remoteCallbackDied(E callback, Object cookie);
   }

   private final class RemoteCallbackListWithDiedCB<E extends IInterface> extends RemoteCallbackList<E> {
      IRemoteCallbackDied<E> mRemoteCallbackDied;

      public RemoteCallbackListWithDiedCB(IRemoteCallbackDied<E> mRemoteCallbackDied)
      {
         this.mRemoteCallbackDied = mRemoteCallbackDied;
      }

      @Override public void onCallbackDied(E callback, Object cookie){
         super.onCallbackDied(callback, cookie);
         this.mRemoteCallbackDied.remoteCallbackDied(callback, cookie);
      }
   }

然后，我创建实施 IRemoteCallabackDied ：

   private final IRemoteCallbackDied<IModConnClient> mRemoteCallbackDied = new IRemoteCallbackDied<IModConnClient>() {
      public void remoteCallbackDied(IModConnClient mModConnClient, Object cookie)
      {
         Log.v("my_tag", "remote callback died!");
         /*
          * Some code
          */
      }
   };

和，终于，我的回调列表的定义就是这样：

and, finally, my callback list is defined just like that:

private RemoteCallbackListWithDiedCB<IModConnClient> mClients = new RemoteCallbackListWithDiedCB<IModConnClient>(mRemoteCallbackDied);
