这里列出的程序不适用于Android 7 (Nougat)[可能也不适用于Android 6，但我无法验证]。你不能直接在Nougat下拉。apk文件(除非在根模式下，但这需要一个根手机)。但是，您可以使用adb shell将.apk复制到电话上的备用路径(例如/sdcard/Download)，然后您可以从备用路径进行adb拉取。

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

我得到了一个不存在的错误

我是这么做的

adb shell pm list packages -f | findstr zalo
package:/data/app/com.zing.zalo-1/base.apk=com.zing.zalo

adb shell
mido:/ $ cp /data/app/com.zing.zalo-1/base.apk /sdcard/zalo.apk
mido:/ $ exit


adb pull /sdcard/zalo.apk Desktop

/sdcard/zalo.apk: 1 file pulled. 7.7 MB/s (41895394 bytes in 5.200s)

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\""

C:\Users\xyz>adb shell pm list packages -f | findstr whatsapp
package:/data/app/com.whatsapp-1/base.apk=com.whatsapp

C:\Users\xyz>adb pull /data/app/com.whatsapp-1/base.apk Desktop
/data/app/com.whatsapp-1/base.apk: 1 f.... 13.8 MB/s (32803925 bytes in 
2.269s)

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