我想编写一个应用程序，将会把保持当前通话，然后添加一个新的呼叫。由于这是可以做到通过手动pressing按钮，我会觉得有一种方法以编程方式做到这一点，但我不能在SDK什么。

I would like to write an app that will put the current call on hold, then add a new call. Since this can be done by manually pressing buttons, I would think there is a way to do it programmatically, but I cannot find anything in the sdk.

TIA

推荐答案

由于Phone.apk无法从Android SDK直接编译，因为它使用对象和方法是不是在SDK公开的，你可能会有建立一个应用程序作为平台的一部分，所以你可以访问相同的对象和方法，像Phone.apk的应用程序一样。

Since the Phone.apk can't compile directly from the android SDK because it uses objects and methods that are not publicly available in the SDK, you would probably have to build an app as part of the "platform" so you can have access to the same objects and methods that an app like Phone.apk does.
