你可以这样做:

Download and install APK Extractor in your device. It is free, and is compatible in almost all of the Android devices. Another plus point is it does not even require root or anything to work. After you have it installed, launch it. There you will see a list of apps which are in your device, which include the apps you’ve installed later, along with the system apps. Long press any app you want to extract (you can select multiple or all apps at once), and click on the extract option you see in the top. You will also have the option to share via Bluetooth or messaging. You’re done, you will see the extracted apps as AppName_AppPackage_AppVersionName_AppVersionCode.apk, which will be saved in the path /sdcard/ExtractedApks/ by default.

如果你知道(或者你能“猜”到)。apk的路径(它的格式似乎是/data/app/com.example.someapp-{1,2，..}.apk to)，那么你也可以从/data/app中复制它。这个功能甚至在我的非根安卓手机上也能运行。

只需使用终端模拟器应用程序(比如这个)并运行:

# step 1: confirm path
ls /data/app/com.example.someapp-1.apk
# if it doesn't show up, try -2, -3. Note that globbing (using *) doesn't work here.
# step 2: copy (make sure you adapt the path to match what you discovered above)
cp /data/app/com.example.someapp-1.apk /mnt/sdcard/

然后你可以把它从sd卡移到任何你想要的地方(或附加到电子邮件等)。最后一点在技术上可能是可选的，但它使您在尝试使用.apk文件时更加轻松。

试试这个bash命令来备份你所有的应用程序:

for package in $(adb shell pm list packages -3 | tr -d '\r' | sed 's/package://g'); do apk=$(adb shell pm path $package | tr -d '\r' | sed 's/package://g'); echo "Pulling $apk"; adb pull -p $apk "$package".apk; done

这个命令来自于Firelord的脚本。我只是将所有apks重命名为它们的包名，以解决elcuco的脚本问题，即相同的base.apk文件被覆盖在Android 6.0“棉花糖”及以上。

注意，这个命令只备份第三方应用，因为我不认为备份内置应用有什么意义。但如果你也想备份系统应用程序，只需省略-3选项。

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

不需要root:

这段代码将获得第三方包的路径和名称，以便您可以轻松识别您的APK

adb shell pm list packages -f -3

输出将是

包:/ / app / XX.XX.XX.apk = YY.YY.YY数据

现在使用下面的代码拉出这个包:

adb pull /data/app/XX.XX.XX.apk

如果你在C:>\中执行上面的cmd命令，那么你会在那里找到这个包。
