我想用反射来访问电话API的一些未发布的功能。目前,我在实例化serviceManager
对象时遇到问题,需要将“电话”服务作为活页夹来使用,然后我可以使用它来实例化拨打电话,结束呼叫等所需的电话对象...反思访问高级电话功能
当前拨打电话时
serviceManagerObject = tempInterfaceMethod.invoke(null, new Object[] { new Binder() });
它返回一个nullPointerException。我相信这必须做与创建一个新的活页夹,而不是发送相应的粘合剂(这我不清楚其中的一个为宜)
public void placeReflectedCall() throws ClassNotFoundException,
SecurityException, NoSuchMethodException, IllegalArgumentException,

serviceManagerNativeClass = Class.forName(serviceManagerNativeName);
Method getService = // getDefaults[29];
serviceManagerClass.getMethod("getService", String.class);
Method tempInterfaceMethod = serviceManagerNativeClass.getMethod(
"asInterface", IBinder.class);
// this does not work
serviceManagerObject = tempInterfaceMethod.invoke(null,
new Object[] { new Binder() });
IBinder retbinder = (IBinder) getService.invoke(serviceManagerObject,
"phone");
Method serviceMethod = telephonyStubClass.getMethod("asInterface",
IBinder.class);
telephonyObject = serviceMethod
.invoke(null, new Object[] { retbinder });
telephonyCall = telephonyClass.getMethod("call", String.class);
telephonyEndCall = telephonyClass.getMethod("endCall");
telephonyAnswerCall = telephonyClass.getMethod("answerRingingCall");
telephonyCall.invoke(telephonyObject, number);
}
“目前我有麻烦实例化一个对象的ServiceManager”是你给有关错误或问题的唯一信息。你给我们的代码。现在告诉我们它在做什么或不做什么是意外的,以及如何知道它不能正常工作。 – 2010-01-04 18:14:54
