apktool b 回编译error: No resource identifier found for attribute 'bgType' in package 解决

尝试回编译qq时出现如下错误：

c:\>apktool b qq -o qqrepack.apk
I: Using Apktool 2.4.1
I: Checking whether sources has changed...
I: Checking whether sources has changed...
I: Checking whether sources has changed...

W: d:\qq\res\layout\about.xml:8: error: No resource identifier found for attribute 'bgType' in package 'com.tencent.mobileqq'
......

改用-r参数：反编译时不解包资源，再回编译即可解决：

c:\>apktool /?
Apktool v2.4.1 - a tool for reengineering Android apk files

usage: apktool
......
 -o,--output        The name of folder that gets written. Default is apk.out
 -p,--frame-path    Uses framework files located in .
 -r,--no-res             Do not decode resources.

反编译：

c:\>apktool d -r qq.apk

签名

C:\>"C:\Program Files\Java\jdk1.8.0_241\bin\jarsigner.exe"  -verbose -keystore abc.keystore -signedjar qqrepack_signed.apk qqrepack.apk abc.keystore

经测试，回编译之后的 APK 无法运行，原因在于R文件夹并未打包进去，而是打包了一个 Res 文件夹，导致安装后 APP 图标都显示不正确，故需要用7-zip手动删除 qqrepack.apk 内的 Res 文件夹，然后把原版 qq.apk 内的 R 文件夹拷贝到 qqrepack.apk 内，再重新签名即可使用。

PS1:要用破解版的QQ，否则会闪退
PS2:也可将原版QQ内的R文件夹解压后，拷贝到反编译出的qq\build\apk\内，这样回编译时回自动添加到qqrepack.apk内，无需再通过7-zip操作
