使用反射更改Android上的SIM卡PIN码

Question

I would like to change SIM card PIN number using java reflection. Final app will be installed in system/app.

The code I'm using is:

String ICCCARD_CLASS = "com.android.internal.telephony.IccCard";
String PHONEBASE_CLASS = "com.android.internal.telephony.PhoneBase";

Object phoneBaseObject = Class.forName(PHONEBASE_CLASS).getConstructor();
Object iccCardObject = Class.forName(ICCCARD_CLASS).newInstance(); 
Method iccCardMethod = Class.forName(ICCCARD_CLASS).getMethod("changeIccLockPassword", String.class, String.class, Message.class);

//Method arguments are...
Object arglist1[] = new Object[3];
arglist1[0] = "1111"; //oldPass
arglist1[1] = "2222"; //newPass
arglist1[2] = new Message(); //message handler (not needed)

iccCardMethod.invoke(iccCardObject, arglist1);

But, I'm getting a lot of exceptions like "no such method", "instantiation exception"... In my Android project packages for IccCard and PhoneBase are not created.

似乎确实需要通过修改后的classes.dex来重建android.jar 。
