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/

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)

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.

android中如何提取apk文件的详细说明，请访问:http://appslova.com/how-to-extract-apk-files-in-android/

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

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。

完成@Yojimbo的回答，这是我所做的(只适用于Linux/Mac，不会在Windows上开箱工作……可能在git的bash shell中):

for i in $(adb shell pm list packages -f -3 | cut -d= -f 1 | cut -d ":" -f 2); do adb pull $i; done

这是一个丑陋的bash，但工作:)

编辑: 它不再适用于AndroidM:所有文件都命名为“base.apk”在另一个目录下。应该是“微不足道的”修复。
