With each update of the Android operating system, the process of extracting installation files becomes more and more confusing. Google developers constantly hide system directories, and file managers lose access to the folder Android/data without granting special permissions. However, the need to save APK file remains relevant: be it creating a backup copy of your favorite game, transferring an application to a device without the Internet, or saving an old version of a app that is no longer supported in the official store.
In this article we will analyze not only standard methods available to the average user, but also advanced techniques for those who wants to get full control over his device. You will learn how to bypass the restrictions of the new security policy of Android 11 and higher, which tools allow you to “pull” an application directly from memory, and why saving the certificate signature is as important as the installer itself.
Why save APK files on the device at all
Many users rely solely on Google Play or alternative application stores, considering manual file management a waste of time. However, having a local copy of the installer (.apk) provides a number of significant advantages, especially in the long term. This is a kind of digital insurance that allows you not to depend on the whims of developers or changes in distribution policy.
Firstly, this is protection against removal of applications from stores. Quite often, developers delete their projects for various reasons: violating the rules of the site, closing the studio, or simply wanting to stop supporting them. If you have installation fileon hand, you can continue to use the app even after it disappears from the storefront. Secondly, it is possible to roll back to a stable version. New updates often bring bugs, and having an old version of the APK allows you to quickly restore the functionality of the application.
⚠️ Attention: Downloading and installing APK files from unverified sources carries security risks. Always check the digital signature and hash of the file if you do not take it from your device.
In addition, saving the APK is necessary for transferring data to devices that do not have access to the Internet or Google services. This is often found on specialized tablets, Chinese versions of smartphones, or corporate gadgets with limited network access. Having a library of installers creates a self-contained ecosystem, independent of external servers.
Using specialized extractor applications
The easiest and most accessible way for most users is to use third-party utilities designed specifically for these purposes. Such apps scan the list of installed applications, find the path to their source code in the system partition and copy it to a memory area accessible to the user. This method does not require root access and works on most modern versions of Android.
One of the most popular tools is APK Extractor. The interface of such applications is usually extremely simple: you see a list of all installed apps, select the one you need and click the “Extract” button. The application automatically creates a copy of the file in the folder ExtractedApks in internal storage. Some advanced versions can work not only with regular APKs, but also with the XAPK or AAB (Android App Bundle) format, which is now being actively implemented in Google Play.
It is important to understand the difference between a regular APK and separated packages. Modern applications often consist of several parts: base code, resources for a specific screen resolution, language packs and libraries for a specific processor. A simple extractor can only save the base file, which will not install without the rest of the components. Therefore, when choosing a utility, pay attention to format support .apks or the ability to export all split packages at once.
Before bulk extracting applications, create a separate folder on the SD card. This will make it easier to find the files you need in the future and free up space in the internal memory.
The usage process usually looks like this:
- 📱 Install the extractor application from a reliable source.
- 🔍 Find the desired app in the list (you can search by name).
- 💾 Click the export button and wait for the notification of successful completion.
- 📂 Move the resulting file to cloud storage or to a computer for reliability.
Manual copying through a file manager without Root
For those who do not want to install unnecessary software, there is an opportunity to find APK file manually using a standard or advanced file manager, for example Total Commander or Solid Explorer. However, there is a nuance here: starting with Android 10 and especially in Android 11+, access to system folders is strictly limited. The direct path to application files lies through the directory /data/app/, where ordinary managers are not allowed without special privileges.
However, there is a workaround through the system settings. If you go to Settings → Applications, select a specific app and click on the three dots in the corner (or the “Advanced” button), sometimes you can see an “Application Details” item or similar, which opens a page in the style of old Android. But this method is unstable on different shells. A more reliable way is to use the “Share” function or built-in shortcut creation tools, which some managers interpret as the path to the file.
If your file manager supports access to system partitions via SAF (Storage Access Framework), you can go to the path:
/storage/emulated/0/Android/data/However, you APK files are not located there. They are deeper. In new versions of Android, the only way to get to them without root is to use special settings shortcuts or ADB (which is discussed below). Some managers, such as MT Manager, may request permission to access the folder Android, but even this does not always provide access to /data/app.
⚠️ Attention: On Android 11 and later, direct access to the folder
/data/appthrough standard file managers is blocked by the security system. Attempts to bypass this can lead to unstable operation of the explorer.
Therefore, the manual method without third-party extractors on new versions of the OS is becoming less and less effective. The system deliberately isolates application executable files from the user space to prevent them from being modified by malware.
Extracting APK via computer and ADB (for advanced)
The most reliable and universal method that works on any version of Android without exception is using USB debugging and utilities ADB (Android Debug Bridge). This method requires connecting the smartphone to the computer, but gives a guaranteed result and allows you to unload even those applications that are hidden from regular extractors.
First, you need to activate developer mode on your device. Go to Settings → About phone and quickly click on the “Build number” item 7 times until a notification appears indicating that you have become a developer. Then in the “For Developers” menu that appears, turn on the toggle switch USB debugging.
Connect your phone to the PC with a cable. On your computer, open a command prompt (terminal) in the ADB tools folder. The first command is needed to check the connection:
adb devicesA request for debugging permission will appear on the phone screen - confirm it. Next, you need to find out the full package name of the desired application. This can be done with the command:
adb shell pm list packagesThe list will be huge, so it is better to use search. For example, to find the Telegram package:
adb shell pm list packages | grep telegramHaving received the package name (for example, org.telegram.messenger), we can find out the path to the APK file:
adb shell pm path org.telegram.messengerThe system will return a path like package:/data/app/.... All that remains is to copy the file to your computer:
adb pull /data/app/org.telegram.messenger-xyz/base.apk C:\Downloads\telegram.apk☑️ Preparing to work with ADB
This method is ideal for saving “clean” files without garbage. In addition, through ADB, you can upload all related split packages at once if the application uses the Android App Bundle format, although the command for this will be more complicated and will require the use of additional flags or scripts.
Features of saving Split APK and Android App Bundle
The modern Android ecosystem has switched to the format Android App Bundle (.aab). When you download an app from Google Play, the store doesn't give you one big file. Instead, it generates a set of APK files optimized specifically for your device: a base module, a graphics module, a language module, and so on. They are installed on the device as a single unit, but physically represent several files.
If you try to save such an application in the usual way, you risk receiving only the base APK. If you try to install it on another device (or even on the same device after a reset), the system will throw an error because the necessary resources will not be available. The problem is solved by using tools that can work with split packages.
| File type | Description | Difficulty of extraction | Compatibility |
|---|---|---|---|
| Universal APK | Single file for all devices | Low | High |
| Split APK | Set of files (base + resources) | Medium | Requires a special installer |
| App Bundle (.aab) | Initial package for the store | High (needs a converter) | Not installed directly |
| XAPK | APK + OBB data in one archive | Medium | Requires XAPK installer |
To work with Split APK on your computer, there are utilities like Sai (Split APKs Installer) or scripts for ADB that can collect all parts into one archive .apks. On the phone itself, some advanced extractors automatically pack all parts into one file when exporting, which is the most convenient option for the user.
What if you only have an .aab file?
An .aab file cannot be installed directly on the phone. It needs to be converted to APK. To do this, you can use online conversion services or Google's bundletool utility on your computer, which will generate a set of APK files from the bundle.
Where to store and how to restore saved files
After successfully extracting the APK file, it is critical to ensure its safety. The internal memory of a smartphone is not the most reliable place: if you reset the settings, flash the firmware, or break the device, all data will be lost. It is recommended to use the strategy three copies: one on your phone for quick access, the second on your computer or external hard drive, and the third in the cloud storage.
When restoring the application, just click on the saved file. If this is a regular APK, the installation will proceed as standard. If you saved a split package or XAPK, you will need a special installer (for example, the same Sai or the built-in installer from a file manager that supports these formats). Before installing, do not forget to allow installation from unknown sources in the security settings.
It is also worth considering the version of Android for which the application was saved. An app running on Android 14 may not run on Android 8 due to API changes. Therefore, when archiving, it is useful to add the OS version or save date to the file name.
⚠️ Attention: Settings interfaces and file paths may differ depending on the manufacturer’s shell (MIUI, OneUI, ColorOS). If you do not find the described items, use the search in the phone settings.
The most reliable way to save an Android app 11+ is to use ADB through a computer or specialized extractors with Split APK support.
Is it possible to save the APK of system applications?
Yes, this is possible, but for access to system applications applications (those installed in the partition /system/app) in most cases will require root access. Without them, many extractors simply will not see these applications in the list or will not be able to copy their files from the protected memory area.
Will the saved APK work on another phone?
If it is a universal APK - yes, most likely. If this is a Split APK optimized for a specific processor or screen resolution of another phone, the installation may fail or the application will crash. Always check the processor architecture (arm64-v8a, armeabi-v7a) of the target device.
How to know if a file is a Split APK?
Usually such files have the extension .apks or are a set of files in a folder. If you get a "Package was not installed" or "Application not installed" error when you try to install with the standard batch installer, it is most likely a split package that requires a custom installer.
Do saved APKs take up a lot of space?
The size depends on the application. Simple utilities weigh several megabytes, while modern graphics games can take up 2-5 GB, especially if you save them with cache files (OBB). Regularly audit your APK library.
