    各位大神,请问这种类型的dex文件要怎么解密啊,用np管理器和mt管理器都显示不支持此种类型的解密,这个是其中一段代码:
    
    .class public Lezy/assist/compat/SettingsCompat;
    .super Ljava/lang/Object;
    .source "SettingsCompat.java"
    
    # static fields

    .field private static final OP_SYSTEM_ALERT_WINDOW:I = 0x18
    
    .field private static final OP_WRITE_SETTINGS:I = 0x17

    贴il一般是没用的
    dex加密是指对原dex做了一层上层封装,或者直接修改控制流了做混淆
    所以贴出来的很可能是封装的壳代码或者混淆代码
    这个要具体情况具体分析
    一般来说有些是通用的,可以用通用工具做分析
    如果上vmp之类的话只能靠人读和写代码分析
    如果是运行时解密可以考虑尝试dump下来
