砸壳的工具千千万,但是FDex2 是最有能耐的,我尝试过各种壳,都是秒砸的。特别说明一下,360的壳,oncreated 方法还是空的,但是其他大部分内容还是有的,反正是可以参考一下的。

 

安装环境:

 

1,安卓手机root ,必须root,记住是必须,只支持6.0 或者更低的版本,太高版本也不行。

Root 手机很好找,淘宝买个nexus 手机,然后家里用工具就可以root,为什么不 推荐其他手机,是因为其他手机现在root 特别麻烦,买个旧手机就几百块钱。

2,安装virtual xposed

Xposed 的安装,使用,之前已经讲过了,这里不在赘述。

3,安装Fdex2.

4, 激活FDex2 模块

 

开始砸壳:

安装app 到xposed, 启动FDex2 ,然后配置需要砸壳的app,

再提示的目录,就可以找到脱壳后的dex 文件。

Fdex2 的程序代码:

        xsp.makeWorldReadable();
        xsp.reload();

                Class cls = (Class) param.getResult();
                if (cls == null) {
                    //XposedBridge.log("cls == null");
                    return;
                }
                String name = cls.getName();
                XposedBridge.log("当前类名:" + name);
                byte[] bArr = (byte[]) Dex_getBytes.invoke(getDex.invoke(cls, new Object[0]), new Object[0]);

                File file = new File(dex_path);
                if (file.exists()) return;
                writeByte(bArr, file.getAbsolutePath());
            }
            } );
    }
 
    public void initRefect() {
        try {
            Dex = Class.forName("com.android.dex.Dex");
            Dex_getBytes = Dex.getDeclaredMethod("getBytes", new Class[0]);
            getDex = Class.forName("java.lang.Class").getDeclaredMethod("getDex", new Class[0]);
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        }
 
    }
 
    public  void writeByte(byte[] bArr, String str) {
        try {
            OutputStream outputStream = new FileOutputStream(str);
            outputStream.write(bArr);
            outputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
            XposedBridge.log("文件写出失败");
        }
    }
}
