如上所述，您可以通过使用adb中的pull命令来获得apk。

由于您正在讨论已安装的应用程序，请继续查看Android文件系统的/data/app目录。你会在那里找到APK。

然后使用adb命令- adb pull /data/data/appname.apk

对于从设备检索的每个apk文件，所有这些答案都需要多个步骤。1. 2.确定包名。找到文件，然后3。下载它。我构建了一个简单的apk_grabber python脚本，用于匹配给定正则表达式的任何应用程序，然后将这些apks反编译到jar文件中。

不需要Root和ADB工具的方法。 从游戏商店安装MyAppSharer应用程序。

APK从设备下载到桌面的步骤

A)确保您的运行(模拟器/真实设备)。使用该命令检查

adb devices

B)选择设备中安装的所有可用软件包列表。可以使用grep命令选择要下载的软件包。

adb shell pm list packages
adb shell pm list packages -f -3

输出(可用包的列表)

package:/data/app/com.example.mytestapplication-sOzKi5USzfbYLPNDmaaK6g==/base.apk=com.example.mytestapplication
package:/data/app/com.example.myapplication-nd1I4FGnTZnQ9PyRbPDHhw==/base.apk=com.example.myapplication

C)从上面的链接复制包(你喜欢下载的)。在我们的案例中，我选择这个(com.example.myapplication)包

Syntax : adb shell pm path [your_package_name]
Command: adb shell pm path com.example.myapplication

输出

package:/data/app/com.example.myapplication-nd1I4FGnTZnQ9PyRbPDHhw==/base.apk

D)最后，从您的(模拟器/真实设备)下载APK

Syntax : adb pull /data/app/[your_package_name]-1/base.apk  [your_destination_path]
Command: adb pull /data/app/com.example.myapplication-3j4CVk0Tb2gysElgjz5O6A==/base.apk /Users/$(whoami)/Documents/your_apk.apk

示例:试图将CertInstaller.apk文件拉到本地机器(Mac)

adb pull /system/app/CertInstaller/CertInstaller.apk /Users/$(whoami)/Documents/APK/download_apk/

E)在您的本地目录中确认

ls -la /Users/$(whoami)/Documents/

还有另一个bash脚本(即可以用于大多数基于unix的系统)。基于佩德罗·罗德里格斯的回答，但更容易使用。

对佩德罗版本的改进:

Original approach did not work for me on Android 7: adb pull kept complaining about no such file or directory while adb shell could access the file. Hence I used different approach, with temporary file. When launched with no arguments, my script will just list all available packages. When partial package name is provided, it will try to guess the full package name. It will complain if there are several possible expansions. I don't hardcode destination path; instead APKs are saved to current working directory.

保存到一个可执行文件:

#!/bin/bash
# Obtain APK file for given package from the device connected over ADB

if [ -z "$1" ]; then
    echo "Available packages: "
    adb shell pm list packages | sed 's/^package://'
    echo "You must pass a package to this function!"
    echo "Ex.: android_pull_apk \"com.android.contacts\""
    exit 1
fi

fullname=$(adb shell pm list packages | sed 's/^package://' | grep $1)
if [ -z "$fullname" ]; then
    echo "Could not find package matching $1"
    exit 1
fi
if [ $(echo "$fullname" | wc -l) -ne 1 ]; then
    echo "Too many packages matched:"
    echo "$fullname"
    exit 1
fi
echo "Will fetch APK for package $fullname"

apk_path="`adb shell pm path $fullname | sed -e 's/package://g' | tr '\n' ' ' | tr -d '[:space:]'`"
apk_name="`basename ${apk_path} | tr '\n' ' ' | tr -d '[:space:]'`"

destination="${fullname}.apk"

tmp=$(mktemp --dry-run --tmpdir=/sdcard --suffix=.apk)
adb shell cp "${apk_path}" "$tmp"
adb pull "$tmp" "$destination"
adb shell rm "$tmp"

[ $? -eq 0 ] && echo -e "\nAPK saved in \"$destination\""
