目前 市面上你能买到的一些安卓刷量变机工具例如 008K、变机宝等等 使用的都是XPOSED框架来修改手机的机型。这种修改方式目前是一种主流技术，主流技术的优点就是兼容性好、开发(包括文档支持、社区支持、第三方模块)成本低、稳定性高等特点。但对于当前项目来说，主流技术并不是一个好的解决办法，因为主流技术不光你了解，APP的厂商的技术人员也很了解，而且一般规律来看，厂商的技术实力、人力、财力以及这三方面的积累，不是一个小团队的作者可以对抗的。
目前改机软件所实现的修改机型项目汇总起来分为以下几类
1：手机唯一身份标志
这个很好理解，主要包括 IMEI IMSI ICCID 等等这些全球唯一的身份标志，来表示这台手机的独立性，另外要实现一些编号的校验位运算，一般情况下，这些标志身份的序号都有校验位和一些固定的格式和算法，这里有很多渠道和积分墙是对这些序号的合法性有检测的。
2 : 唯一标志衍生信息
这个衍生信息就有很多项了，例如一些改机软件 随便的把某个厂商的型号和一个合法的IMEI结合在一起，殊不知IMEI的前6位为TAC，是每个机型独有的身份标志，随便搭配后，一定会被检测出来的。再例如联通的IMSI是46001开头，移动和电信的就不一样，IMSI,ICCID,NUMBER,运营商,网络制式,mnc,mcc这些信息最起码是要匹配的。
3：环境信息
环境信息分为两部分 ①：手机内部环境 包括你的系统特定信息，用户特定信息。②：手机外部环境：基站信息、GPS信息、WIFI信息等等。
本文中所有的操作都基于Android Studio环境。下面进入实战操作环节！
1 首先创建一个APP，并配置XPOSED的开发环境，配置过程可以参考以下两篇文章，此处不再重复。
http://www.cnblogs.com/csonezp/p/5177928.html
http://www.open-open.com/lib/view/open1451364108964.html
2 配置好XPOSED环境后，在该APP中创建HOOK类 本文为MainHook,该类必须继承IXposedHookLoadPackage
代码:
public class MainHook implements IXposedHookLoadPackage
{
@Override
public void handleLoadPackage(XC_LoadPackage.LoadPackageParam lpparam) throws Throwable
{
//xposed程序入口 do something...
}
}
3 实际修改项
目前市面上的很多改机软件都没有修改第二处的IMEI
另外一个位置是在com.android.internal.telephony.PhoneSubInfo类中，
导致有些反作弊系统读取这个位置的IMEI值后不会下分
代码:
HTool.XHookMethod(android.telephony.TelephonyManager.class.getName(),mLpp.classLoader, "getDeviceId", GetCatValue("imei"));
HTool.XHookMethod("com.android.internal.telephony.PhoneSubInfo",mLpp.classLoader, "getDeviceId", GetCatValue("imei"));

new XC_MethodHook()
{
protected void afterHookedMethod(MethodHookParam param) throws Throwable
{
//每个安卓系统中 至少存在5个以上的MAC地址
//但大多数软件只修改了MAC和BSSID
//真正的MAC修改是在此处理函数中监听每次访问.
}
}});
//蓝牙信息
HTool.XHookMethod(BluetoothAdapter.class.getName(),mLpp.classLoader,"getAddress", GetCatValue("bluemac"));
HTool.XHookMethod(BluetoothAdapter.class.getName(),mLpp.classLoader, "getName", GetCatValue("bluename"));
//设置手机信息 无论手机是否插入了sim卡 都会模拟出SIM卡的信息 APP获得SIM卡消息时返回该手机已有SIM卡
HTool.XHookMethod(android.telephony.TelephonyManager.class.getName(),mLpp.classLoader, "getPhoneType", TelephonyManager.PHONE_TYPE_GSM);

HTool.XHookMethod(android.telephony.TelephonyManager.class.getName(),mLpp.classLoader, "getSimState", TelephonyManager.SIM_STATE_READY);
HTool.XHookMethod(android.telephony.TelephonyManager.class.getName(),mLpp.classLoader, "hasIccCard", true);
//修改手机系统信息 此处是手机的基本信息 包括厂商 信号 ROM版本 安卓版本 主板 设备名 指纹名称等信息

new XC_MethodHook()
{
//为了防止某些APP跳过Build类 而直接使用SystemProperties.native_get获得参数
}});
//修改系统版本 我看到世面上的软件基本上都是不能修改系统版本的 从而造成了刷量后 很多渠道最终会显示你的APP用户全部使用的某一系统版本
//这样的话数据就太假了.

XposedHelpers.setStaticObjectField(android.os.Build.VERSION.class, "SDK", GetCatValue("apilevel"));

...........................
//此处的mnc和mcc必须和系统中其他关于运营商的数据对应!
}});
//修改ANDROID_ID
XposedHelpers.findAndHookMethod(android.provider.Settings.Secure.class.getName(),mLpp.classLoader, "getString",
new Object[] {ContentResolver.class,String.class,
new XC_MethodHook()
{
...............................
//此处会根据传入的String参数 判断返回值 其中包括比较关键的数据就是android_id
}});
//防止APP使用Runtime.exec方式获取一些特定的系统属性
XposedHelpers.findAndHookMethod(Runtime.class.getName(),mLpp.classLoader, "exec",new Object[] {String.class,String[].class, File.class,
new XC_MethodHook()
{
//一些APP从JAVA层获得到了数据 还会从shell(native)层获得一些更底层的数据 来判断用户的合法性
//经常用到的有 cat、getprop、ifconfig等等命令，当exec执行这些命令后 往往会返回一些手机的真实信息
//因为框架和处理方式不同，...部分此处根据自己需求，编写重定向返回值的过程...
}});
//修改位置信息
XposedHelpers.findAndHookMethod(LocationManager.class.getName(),mLpp.classLoader, "getLastKnownLocation",
new Object[] {String.class,
new XC_MethodHook()
{
..........................
//返回预先设置好的经纬度信息以伪装地理位置
}});
HTool.XHookMethod(Location.class.getName(),mLpp.classLoader, "getLatitude", latitude);
HTool.XHookMethod(Location.class.getName(),mLpp.classLoader, "getLongitude", longitude);
//修改GSM制式手机的基站信息
HTool.XHookMethod(android.telephony.gsm.GsmCellLocation.class.getName(),mLpp.classLoader, "getLac", GsmLac);
HTool.XHookMethod(android.telephony.gsm.GsmCellLocation.class.getName(),mLpp.classLoader, "getCid", GsmCid);
//修改CDMA制式手机的基站信息
HTool.XHookMethod(android.telephony.cdma.CdmaCellLocation.class.getName(),mLpp.classLoader, "getBaseStationLatitude", CdmaLatitude);
HTool.XHookMethod(android.telephony.cdma.CdmaCellLocation.class.getName(),mLpp.classLoader, "getBaseStationLongitude", CdmaLongitude);
HTool.XHookMethod(android.telephony.cdma.CdmaCellLocation.class.getName(),mLpp.classLoader, "getBaseStationId", CdmaBid);
HTool.XHookMethod(android.telephony.cdma.CdmaCellLocation.class.getName(),mLpp.classLoader, "getSystemId", CdmaSid);
HTool.XHookMethod(android.telephony.cdma.CdmaCellLocation.class.getName(),mLpp.classLoader, "getNetworkId", CdmaNid);
//模拟手机的APP列表
XposedHelpers.findAndHookMethod("android.app.ApplicationPackageManager",mLpp.classLoader, "getInstalledPackages",new Object[] {int.class,
new XC_MethodHook()
{
//此处模拟正常用户的APP列表 其中随机的增加和删除一些常用APP 以达到每个手机的APP有很大的随意性和合理性
}});
XposedHelpers.findAndHookMethod("android.app.ApplicationPackageManager",mLpp.classLoader, "getInstalledApplications",new Object[] {int.class,
new XC_MethodHook()
{
//此处模拟正常用户的APP列表 其中随机的增加和删除一些常用APP 以达到每个手机的APP有很大的随意性和合理性
}});
//防止APP的VPN SOCK5 HTTP代理检测
XposedHelpers.findAndHookMethod(java.net.NetworkInterface.class.getName(),mLpp.classLoader, "getNetworkInterfacesList",new Object[] {
new XC_MethodHook()
{
........................................
//此处对于一些连接信息 对JAVA做了隐藏处理 但对于系统和Native层依然是可见的 所以APP不会检测到代理 但代理却可以正常的运行...
}});
以上这些做下来 从信息采集上基本可以过市面上70%的系统了 对于某些系统的高级检测，则需要我们采用更高级的处理方式才能攻破对方的防线，这些处理方式我们随后会讲到。
但目前推广市场上 不光是采用技术手段 还采取大数据分析等方式判断你的数据是否合格 所以想把这个作为一个项目来做 从技术方面解决工具问题只是刚刚开始。*转载请注明来自看雪论坛@PEdiy.com
贴个利用反射机制来获取imei的代码：（这段代码手机上执行不会调用TelephonyManager.getDeviceId,没有调用shell，没有jni，但是确实能获取到imei）：
TelephonyManager tel = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
Method TelephonyManager_private_getSubscriberInfo = tel.getClass().getDeclaredMethod("getSubscriberInfo");
TelephonyManager_private_getSubscriberInfo.setAccessible(true);
Object iphonesubinfo = TelephonyManager_private_getSubscriberInfo.invoke(tel);
log(iphonesubinfo.toString());
Method getDeviceId = iphonesubinfo.getClass().getDeclaredMethod("getDeviceId");
log(getDeviceId.toString());
getDeviceId.setAccessible(true);
Object deviceid = getDeviceId.invoke(iphonesubinfo);
log("deviceid:" + deviceid.toString());
