一个高效的Apk提取脚本

一个高效的Apk提取脚本

开发者如何将手机上已安装应用的安装包提取导出到电脑上呢？

以前是这样做的，只需要简单三步:

①利用焦点拿到当前打开的应用包名（如果已经知道需要导出的应用包名，可以跳过此步）

adb shell dumpsys window | findStr mCurrentFocus

②知道应用包名后，通过pm获取安装包路径

adb shell pm path $package

③最后就是将apk从手机中pull出来。注意如果路径包含'/base.apk'需要加一个'/'改成'//base.apk'，后面写的脚本有这一步处理。

adb pull $path

还可以更快，更高效，翻出被遗忘的shell记忆，将前面有关联的三步操作写成一个shell脚本。一键提取当前打开的应用安装包，并以包名重命名Apk。传到并没有几个人知道的Github：github/quibbler01/apk-extraction。

#current focused App, output: mCurrentFocus=Window{c053bb9 u0 com.ss.android.ugc.aweme/com.ss.android.ugc.aweme.splash.SplashActivity}
focus=`adb shell dumpsys window | findStr mCurrentFocus`


#extract out {package/class}, output: com.ss.android.ugc.aweme/com.ss.android.ugc.aweme.splash.SplashActivity
classpath=`echo ${focus} | awk '{print $3}'`


#crop string extract package name, output: com.ss.android.ugc.aweme
package=`echo ${classpath%/*}`


#figure out this package install path, output: package:/data/app/com.ss.android.ugc.aweme-bWD-6eHGY_JWxoiHreHc5A==/base.apk
path=`adb shell pm path $package`

#sub path from pm output's, output: data/app/com.ss.android.ugc.aweme-bWD-6eHGY_JWxoiHreHc5A==/base.apk
path=`echo ${path#*/}`

#and replace '/' with '//' if path include '/base.apk',E.g: data/app/com.vivo.easyshare-Q46ic5yVLxvgkiPRkB318Q==//base.apk
if [[ $path =~ /base.apk ]]; then
	path=`echo ${path///base.apk///base.apk}`
fi


#pull apk out renanme with package name
adb pull $path  $package.apk

apk_extraction用着比较方便，突然又想到一个功能点：不带参数运行脚本导出当前手机焦点应用(默认)；如果带着包名参数运行该脚本，那么提取指定包名的安装包，如：

#有空提交到GitHub上
    apk_extraction -p com.tencent.mobileqq
