  A "singleInstance" activity is always at the top of the stack (since it is the only activity in the task), so it is always in position to handle the intent. However, a "singleTask" activity may or may not have other activities above it in the stack. If it does, it is not in position to handle the intent, and the intent is dropped. (Even though the intent is dropped, its arrival would have caused the task to come to the foreground, where it would remain.)

http://llying.iteye.com/blog/220452 CGlib是什么？ CGlib是一个强大的,高性能,高质量的Code生成类库。它可以在运行期扩展Java类与实现Java接口。 当然这些实际的功能是asm所提供的，asm又是什么？Java字节码操控框架，具体是什么大家可以上网查一查，毕竟我们这里所要讨论的是cglib， cglib就是封装了asm，简化了asm的操作，实现了在运行期动态生成新的class。 可能大家还感觉不到它的强大，现在就告诉你。 实际上CGlib为spring aop提供了底层的一种实现;为hibernate使用cglib动态生成VO/PO (接口层对象)。 下面我们将通过一个具体的事例来看一下CGlib体验一下CGlib。  CGlib 2.13  ASM 2.23 以一个实例在简单介绍下cglib的应用。 我们模拟一个虚拟的场景，模拟对表的操作。 1. 开始我们对表提供了CRUD方法。 我们现在创建一个对Tab ...

1、生成       存在这样一个线程，它不断地从driver读取Event，并把它放到RawEvent队列中。这个队列中的RawEvent既有按键，也有触摸、轨迹球等事件。       RawEvent队列中的每个RawEvent最后都会通过一系列转化，最终变为KeyEvent被发送给另外一个线程，即输入线程，也就是一个Activity的主线程。2、传递       KeyEvent传递过程主要可以划分为三步：过滤器、View树、Activity       过滤器部分主要对应着PhoneWindowManager.java中的interceptKeyTq和interceptKeyTi这两个方法。它们的代码可以在frameworks/base/policy/base/phone/com/android/internal/policy /impl/PhoneWindowManager.java中看到。    ...
