这个软件已经被XX无数次了，大家也都知道破解本地VIP的方法。

就是修改 picview\meitui\vip\vipMgr.smali 的 getVipType(Landroid/app/Activity;)I 方法，让它一直返回 0x12c。

这个破解没什么难度，所以今天重发新版破解前，特意修改了另外一样功能，套图下载。

下载套图前，软件先获取当前账户的流量，如果流量不足以下载当前套图，就不让下载。

贴上 picview\meitui\down\DownAsynTask$AsyncAddtoDown.smali 的部分代码，Unicode码已转中文，并添加部分注释。

很明显，如果“.line 163” 上面的 “if-eqz v1, :cond_4”不跳转，就能正常保存下载任务，所以要想下载套图，首先让此处不进行跳转，不然会提示流量不足。

破解方法，在“if-eqz v1, :cond_4”这行前面加#注释掉并保存即可。

接下来，发现就算保存了下载任务，也不能正常下载。抓包发现下载套图时访问的网址如下：

[Java] 纯文本查看 复制代码

http://42.121.110.83/api/imgdown.ashx?u=用户ID&p=图片序号&i=套图ID

直接复制到浏览器里访问，发现看不到图片。考虑服务器端做了判断，不满足条件无法访问图片。

然后想起单张图片可以下载，那么能不能把单张图片的网址弄到套图下载里呢？于是搜索上面网址的调用，定位到：

picview\meitui\down\DownService.smali 的 down()V方法，下面贴出部分代码：

我们现在假想的修改方法是，假设单张图片的下载地址为"http://xxx/xxx/n.JPG"，“n”由“getCcount()I”方法给出。那么我们应该把上面的代码改成：

现在问题简单了，只要确认了网址"http://xxx/xxx/"，就可以下载套图了，由于每个套图的网址都不一样，所以不能单纯的赋值字符串确认网址。

经过查看数据库，发现数据库meitui的db_cached2表里保存有上面说的网址，可以用“套图ID”进行索引，要成功取得这个网址，得添加些数据库查询代码，比较麻烦，放弃。

那还有没有什么地方可以取得上述网址呢？答案是肯定的，只要找到了写入数据库代码的地方，注入代码，把上面的网址输出到文本。

然后根据想法，我先写了个crack.smali放到smali根目录，包含两个方法，get和put，用来读取和写入文本。put方法保存网址到“套图ID.txt”，get方法根据“套图ID”读取保存的网址。

然后在代码里，找到了保存网址"http://xxx/xxx/"的寄存器vx，同时找到保存了“套图ID”的寄存器vy，调用方法: invoke-static {vx, vy}, Lcrack;->put(Ljava/lang/String;Ljava/lang/String;)V

方法作用是保存网址"http://xxx/xxx/" 到文本，文本名为“套图ID.txt”。

那么，上面的代码可以修改成：

crack.smali的get和put方法，可以直接手写smali，但是由于调用方法过多，很容易弄混寄存器，所以还是推荐先写出java代码，编译成apk后再反编译。
示例java代码如下，随便创建个Android Application Project，然后New，class，名称为crack，粘贴下面代码：

                  FileOutputStream outStream = new FileOutputStream(path,false);

                  OutputStreamWriter writer = new OutputStreamWriter(outStream,"gb2312");

                  writer.write(s);

                        e1.printStackTrace();

编译好APK后，反编译该APK，提取crack.smali，把第一行改成“.class public Lcrack;”，这样crack.smali就可以直接放到smali根目录使用。这样做，主要是为了调用方法时写少点代码。

反编译后的crack.smali代码如下：

.class public Lcrack;
.super Ljava/lang/Object;
.source "crack.java"

get方法注入的地方已经说过，put方法注入的地方，我选择了picview/meitui/thumbnailList$6的onClick方法，具体修改地方为：

.method public onClick(Landroid/view/View;)V
    .locals 12    #使用的寄存器范围v0-v11，将此处改为.locals 13，以使用新寄存器v12

    invoke-static {v0}, Lpicview/meitui/thumbnailList;->access$100(Lpicview/meitui/thumbnailList;)Landroid/os/Bundle;

    move-result-object v0

    const-string v1, "type"

    invoke-virtual {v0, v1}, Landroid/os/Bundle;->getString(Ljava/lang/String;)Ljava/lang/String;

    move-result-object v0    #此处通过log.d注入，发现v0为要找的图片网址
        
        move-object v12, v0    #保存网址到v12寄存器

    const-string v1, ".JPG"

    invoke-virtual {v0, v1}, Ljava/lang/String;->contains(Ljava/lang/CharSequence;)Z

#省略

    const-string v3, "info"

    invoke-virtual {v2, v3}, Landroid/os/Bundle;->getString(Ljava/lang/String;)Ljava/lang/String;

    move-result-object v2    #此处经过分析知v2为套图ID
        
        invoke-static {v12, v2}, Lcrack;->put(Ljava/lang/String;Ljava/lang/String;)V    #String s=v12，String t=v2，调用put方法保存网址。

.end method
