安卓第三方短信软件_安卓短信拦截软件_安卓最好的短信软件(3)

初学者可以通过前面介绍静态库的使用方法安卓第三方短信软件，自行实现该类类型的封装定义实现，将其编译为相应的库并在应用实例程序中尝试使用封装的低级文件操作类lowgradefileoperator实现基本文件操作功能。 但是使用类的方式来实现厂模式还有更多的好处. 其一是: 我们可以管理从 nsisupports 接口派生而来的类厂本身的生存期. 当我们试图把多个类厂划分成一组, 然后确定是否能卸载这一组类厂的时候, 这一点非常重要. 另一个好处是: 类厂可以引入其他需要支持的接口. 在我们后面讨论 nsiclassinfo 接口的时候, 我们会看到某些类厂使用这个接口支持信息查询, 诸如这个对象是用什么语言写的, 对象支持的接口等等. 这种派生自 nsisupports 的 "future-proofing" 特性非常关键.xpidl 与类型库定义接口的简单而强劲的方法是使用接口定义语言 - 这实际上是在一个跨平台而语言无关开发环境下定义接口的需求. xpcom 使用的是源自于 corba omg 接口定义语言的变体, 称为 xpidl, 来定义接口, xpidl 可以定义接口的方法, 属性, 常量, 以及接口继承.采用 xpidl 定义接口还存在一些缺陷. 它不支持多继承, 同时 xpidl 定义的方法名不能相同。底层的操作提供实际为应用扩展提供了很好的平台，linux系统通常提供的系统调用都是功能比较单一的底层接口，为应用程序与内核之间操作的接口，实际应用中可以使用高级的语言针对低级系统调用封装实现功能更加强大的方法接口。

Android没有对外公开结束通话的API,要结束通话就必须使用AIDL与电话管理服务进行通信,并调用服务中的API实现结束通话,这样需要android 源码文件ITelephony.aidl添加到项目中，如图所示：

ITelephony.aidl的代码如下：
