Reflection to access advanced telephony features
提问by tsmith
I am trying to use reflection to access some unpublished features of the telephony API. Currently I am having trouble instantiating a serviceManagerobject that is needed to get the "phone" service as a binder which I can then use to instantiate a telephony object which is needed to make a call, end call, etc...
我正在尝试使用反射来访问电话 API 的一些未发布的功能。目前，我在实例化serviceManager获取“电话”服务所需的对象作为绑定器时遇到问题，然后我可以使用它来实例化拨打电话、结束通话等所需的电话对象...
currently when I make the call
目前当我打电话时
serviceManagerObject = tempInterfaceMethod.invoke(null, new Object[] { new Binder() });
it returns a nullPointerException. I believe this has to do with creating a new Binder instead of sending the appropriate binder (which I am unsure of which one is appropriate)
它返回一个 nullPointerException。我相信这与创建一个新的 Binder 而不是发送适当的 Binder（我不确定哪个是合适的）有关

// this does not work

IBinder retbinder = (IBinder) getService.invoke(serviceManagerObject,
"phone");
Method serviceMethod = telephonyStubClass.getMethod("asInterface",

telephonyObject = serviceMethod
.invoke(null, new Object[] { retbinder });
telephonyCall = telephonyClass.getMethod("call", String.class);

telephonyAnswerCall = telephonyClass.getMethod("answerRingingCall");
telephonyCall.invoke(telephonyObject, number);
}

By doing the following
通过执行以下操作
Binder tmpBinder = new Binder();
tmpBinder.attachInterface(null, "fake");
serviceManagerObject = tempInterfaceMethod.invoke(null, new Object[] { tmpBinder });
you will get a ServiceManagerProxy instance, then the next issue happens on the line
你会得到一个ServiceManagerProxy实例，然后下一个问题就行了
telephonyCall.invoke(telephonyObject, number);

I have a solution. Change:
我有一个解决方案。改变：
String serviceManagerName = "android.os.IServiceManager";
to:
到：
String serviceManagerName = "android.os.ServiceManager";

Yes, it's possible! I spent 24 hours of investigating and discovering, and I've found "fresh" solution!
是的，这是可能的！我花了24小时的调查和发现，我找到了“新鲜”的解决方案！
// "cheat" with Java reflection to gain access to
// TelephonyManager's ITelephony getter
Class c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
telephonyService = (ITelephony) m.invoke(tm);

There is a project. and there are important comments (and credits).
有一个项目。并且有重要的评论（和学分）。
In short: copy aidl file, add permissions to manifest, copy-paste source for telephony management.
简而言之：复制aidl文件，添加清单权限，复制粘贴电话管理源。
Some more info for you: You can only send AT commands if you are rooted. Then you can kill system process and send commands but you will need a reboot to allow your phone to receive and send calls.
给你的更多信息：如果你是 root，你只能发送 AT 命令。然后您可以终止系统进程并发送命令，但您需要重新启动才能让您的手机接收和发送呼叫。
I'm very happy! Now my Shake2MuteCall will get an update!
我很开心！现在我的 Shake2MuteCall 将获得更新！
