apktool 简单使用记录

修改APP：车来了

修改内容：首次启动引导页，中间的点素材修改、样式修改

修改前：未选中为白色，选中为蓝色，间距为5dip

修改后：未选中为红色，选中为黑色，间距为0

前后截图如下：

 

修改过程：

一、使用apktool反编译apk

apktool安装根据官网进行：https://ibotpeaches.github.io/Apktool/install/

具体操作：

0.首先确保使用java 1.8或以上

1.下载运行脚本并重命名为apktool.bat，下载地址（官网）：https://raw.githubusercontent.com/iBotPeaches/Apktool/master/scripts/windows/apktool.bat

2.下载最新的apktool并重命名为apktool.jar，下载地址：https://bitbucket.org/iBotPeaches/apktool/downloads/

3.放在一个文件夹，双击运行apktool.bat，会输出用法

4.反编译apk，命令格式：apktool d [ apk文件名 ]

得到了文件夹chelaile，里面有如下文件：

二、寻找和修改

这里是纯粹的凭感觉在搞了

AndroidManifesr.xml  找到<category android:name="android.intent.category.LAUNCHER"/>

猜测启动页面应该是SplashActivity，将其作为本次修改的对象

=> SplashActivity.smali 找到sget p1, Ldev/xesam/chelaile/core/R$layout;->cll_act_splash:I

猜测对应布局文件为cll_act_splash

=> cll_act_splash.xml 发现用了自定义组件GuideView，而且默认设置为gone，在smali文件中有invoke-virtual {v0, v1}, Ldev/xesam/chelaile/app/module/func/GuideView;->setVisibility(I)V，进一步猜测是首次启动才会出现

=> GuideView.smali 找到sget p2, Ldev/xesam/chelaile/core/R$layout;->cll_act_guide:I，猜测对应布局文件为cll_act_guide.xml

=> cll_act_guide.xml里面三个ImageView，应该就是三个点，

根据android:src="@drawable/indicate_dot" 得到对应素材，直接做修改保存；

删除android:padding="5.0dip"（由于这里的修改引起了页面中其他元素在显示上也有变化）

三、重新打包

命令格式：apktool b [ 刚才得到的文件夹 ] -o [ 输出文件名 ]

C:\Users\apk所在文件夹>apktool b chelaile -o newcll.apk
I: Using Apktool 2.4.0
I: Checking whether sources has changed...

出现了一些warning，但是问题不大，第一次使用，就不怎么纠结他了

到这里得到了一个apk，但是不能用，需要签名才能正常安装

四、重新签名

用Auto-sign重新签名，这里参考了一个博客，原文链接：https://blog.csdn.net/sxk874890728/article/details/80486223

下载解压Auto-sign，得到的auto-sign文件夹下有以下文件

将上一步得到的newcll.apk拷贝到解压好的auto-sign文件夹下，执行命令：

java -jar signapk.jar testkey.x509.pem testkey.pk8 newcll.apk cll_signed.apk

就得到了最终可安装使用的apk
