不少使用安卓的朋友都有安装App后就把Apk安装包删掉的习惯，如果从Play商店等途径安装App，更是找不到Apk安装包了。当想要把App分享给他人，或者想要备份App的时候，没有Apk安装包十分不方便。在Windows中我们很难将已安装的程序提取出来做成安装包，不过安卓中和Windows大不一样。我们能够从安卓中将已安装的App提取为Apk安装包，下面我们一起来看看要怎么做吧。
从根目录直接提取Apk
| 管理器系列软件新版本下载： | |
| RE文件管理器(RootExplorer) | 点击本地下载 |
| ES文件管理器 | 点击本地下载 |
由于涉及到系统关键部分，所以提取Apk文件需要root权限。第三方安卓App一般都会安装在根目录下的data/app文件夹中，系统App则安装在根目录下的system/app文件夹内。获取root权限后，用RE管理器、ES文件管理器等支持根目录浏览的文件浏览器进入到相应的文件夹，即可看到各种已安装的App了。
相关目录可以找到已安装的App
如果想要将某个App提取为Apk文件，操作也十分简单。仔细观察可以发现，相应目录下的App本来就是以Apk文件的形式存在的，只需要将对应的Apk文件复制到普通目录下即可。
确认好权限后直接将相应App的Apk文件复制出来即可
当然，这种方法也有不方便之处，用起来稍显复杂，系统目录中的Apk文件命名也混乱，虽然可以通过图标辨认，但仍不算好找。因此，更多人倾向使用第三方软件提前Apk。
使用第三方App提取Apk
无论从根目录直接提取Apk还是使用第三方软件提取，都需要root权限。用第三方App提取Apk有一个好处，就是能够保持Apk的命名，一次性将大量Apk提取到同一目录中。
ES文件管理器带有备份App功能，可提取Apk
目前支持Apk提取的第三方软件很多，安卓平台和PC平台都有，各种XX管家中的“App备份”通常就是描述Apk提取功能了。

此外，还可以从PC端利用adb命令提取Apk，由于这方法比较繁琐，对初级用户并不友好，流传度不广，在这里就不多作介绍了。
后话
对于资深安卓用户来说，将App提取为Apk文件当然不是什么问题。但对于安卓新用户，这却是个不小的麻烦，希望这篇文章能够帮到有相关需要的朋友吧。
Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AMInnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
