我真的很喜欢这些答案。 大多数用于导出和重命名的脚本都是用Bash编写的。 我做了一个小Perl脚本，它可以做同样的事情(它应该在windows和linux的Perl中都可以工作，只在Ubuntu上测试)。

这使用ADB: https://developer.android.com/studio/command-line/adb

download-apk.pl

#!/usr/bin/perl -w
# Automatically export all available installed APK's using adb
use strict;
print "Connect your device...\n";
system("adb", "wait-for-device");
open(my $OUT, '-|', 'adb', 'shell', 'pm', 'list', 'package', '-f');
my $count = 0;
while(my $line = <$OUT>) {
        $line =~ s/^\s*|\s*$//g;
        my ($type, $path, $package) = $line =~ /^(.*?):(.*)=(.*)$/ ? ($1,$2,$3) : die('invalid line: '.$line);
        my $category = $path =~ /^\/(.*?)\// ? $1 : 'unknown';
        my $baseFile = $path =~ /\/([^\/]*)$/ ? $1 : die('Unknown basefile in path: '.$path);
        my $targetFile = "$category-$package.apk";
        print "$type $category $path $package $baseFile >> $targetFile\n";
        system("adb", "pull", $path);
        rename $baseFile, $targetFile;
}

确保adb(.exe)在您的路径或相同目录中 连接你的手机 运行download-apk.pl

输出类似于:

# ./download-apk.pl
Connect your device...

在unix系统上，您可以尝试这个函数:

function android_pull_apk() {
    if [ -z "$1" ]; then
        echo "You must pass a package to this function!"
        echo "Ex.: android_pull_apk \"com.android.contacts\""
        return 1
    fi

    if [ -z "$(adb shell pm list packages | grep $1)" ]; then
        echo "You are typed a invalid package!"
        return 1
    fi

    apk_path="`adb shell pm path $1 | sed -e 's/package://g' | tr '\n' ' ' | tr -d '[:space:]'`"
    apk_name="`adb shell basename ${apk_path} | tr '\n' ' ' | tr -d '[:space:]'`"

    destination="$HOME/Documents/Android/APKs"
    mkdir -p "$destination"

    adb pull ${apk_path} ${destination}
    echo -e "\nAPK saved in \"$destination/$apk_name\""
}

例如:android_pull_apk com.android.contacts 注意:识别包:adb shell pm列表包

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\""

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

适用于所有Android版本的一行代码:

adb shell 'cat `pm path com.example.name | cut -d':' -f2`' > app.apk

这些建议对我都不起作用，因为Android在包名后面附加了一个序列号来生成最终的APK文件名。在最新版本的Android (Oreo和Pie)上，会追加一个不可预测的随机字符串。下面的命令序列是我在非root设备上使用的:

1)确定应用程序的包名。“com.example.someapp”。如果存在以下情况，请跳过此步骤 您已经知道包的名称。

adb shell pm list packages

查看包名列表，并尝试在有问题的应用程序和包名之间找到匹配项。这通常很简单，但请注意，包的名称可以与应用程序的名称完全无关。如果您无法从包名列表中识别该应用程序，请尝试使用浏览器在谷歌Play中找到该应用程序。谷歌Play中应用程序的URL包含包名。

2)获取所需包的APK文件的完整路径名称。

adb shell pm path com.example.someapp

输出看起来像这样 包:/数据/应用/ com.example.someapp apk——2. 或 包:/数据/ app / com.example.someapp-nfFSVxn_CTafgra3Fr_rXQ = = / base.apk

3)使用步骤2中的完整路径名称，将APK文件从Android设备拉到开发箱中。

adb pull /data/app/com.example.someapp-2.apk path/to/desired/destination
