推荐答案

使用反射，你不能访问Android的内部类。在Android的每个应用程序在自己的进程有自己的Dalvik虚拟机实例中运行。类在一个进程中加载​​是不可见的另一个进程。所以，当您尝试从PhoneFactory访问静态变量，你最终加载PhoneFactory类的 unintialized变量的。

You can't access Android's internal classes using reflection. Each application in Android runs in its own process with its own instance of the Dalvik VM. Classes loaded in one process are not visible to another process. So when you try to access static variables from PhoneFactory, you end up loading the PhoneFactory class with unintialized variables.

您最好的将是做任何你想要使用Android API来完成的获得。有几种方法来获得访问一些私人的Andr​​oid服务，但不会让你太过分了。唯一有关的一个短信是在主义服务。你可以看一下穿过ISms.aidl文件present在com.android.internal.telephony包中可使用的方法。

Your best will be to do whatever you want to get done using the Android APIs. There are a few ways to get access to some private Android services, but it won't get you too far. The only relevant one for SMS is the isms service. You can look through the methods available in it in the ISms.aidl file present in the com.android.internal.telephony package.
