jadx反编译

刚发现的一个反编译神器jadx,对比之前的apktool跟dex2jar,jadx胜在可读性好太多,apktool后的smali长的跟汇编语言一样,dex2jar产生的源码也经常出现奇奇怪怪的语法,让我理解不能.

jadx GitHub 地址:https://github.com/skylot/jadx

下载或克隆后,在目录下运行

./gradlew dist

结束后会生成build文件夹,我们需要的脚本文件就在build\jadx\bin下;

我们可以命令行运行jadx.bat脚本产生源码:

jadx -d out classes.dex

也可以打开jadx-gui.bat图形化界面查看源码;

图可能看不清,选一个代码量不大的类贴上看

package com.ddfun.a;

    public long getItemId(int i) {
        return 0;
    }
}

大家可以看到,可读性是不是非常高,这还是在代码混淆的情况下.我们不开启代码混淆来看看:

            }
        } else if (holder.hot_iv.getVisibility() != 8) {
            holder.hot_iv.setVisibility(8);
        }

        ImageLoader.getInstance().loadIcon(ImageLoader.getPrefixedUrl(item.image), holder.icon_iv, ImageLoader.PREVIEWPICSIZE, ImageLoader.PREVIEWPICSIZE, false);
        return convertView;
    }

    public void setData(List l) {
        this.list = l;
        notifyDataSetChanged();
    }

    public synchronized boolean addData(List l) {
        boolean needNotify;
        needNotify = false;
        for (int i = 0; i < l.size(); i++) {
            ActivityBoardBean bean = (ActivityBoardBean) l.get(i);
            if (!this.list.contains(bean)) {

    }

    public long getItemId(int position) {
        return 0;
    }
}

这个图截的是跟图一同一个类,我用txt打开的.大家可以看到,是不是跟源码基本一样了,以后可以选择apktool+jadx来使用,apktool反编译资源文件,清单文件;jadx反编译代码.
