What Is APK Base.apk and How to Use It?

If you are an Android user, you might have heard of APK files and how they can help you install apps that are not available on the official app store. But do you know what base.apk files are and how to use them? In this article, we will explain everything you need to know about base.apk files and how to install, backup, and restore them.

What Is Base.apk?

Base APK refers to the original, unmodified version of an Android application in the form of an APK (Android Package) file. An APK file is the package file format used for distributing and installing apps on Android devices. Base APK is the starting point for any modifications or customizations made to an app. Developers often modify or add features to the base APK, and then distribute the modified version as a new APK file.

Base APKs are typically available on official app stores like Google Play, but they can also be downloaded from other sources, such as third-party app stores or directly from the developer’s website. However, downloading and installing APK files from sources other than the official app store can be risky, as they may contain malware or other harmful software. Users should always exercise caution when downloading and installing APK files from unknown sources, and only download from trusted sources.

You might have come across a file on your phone called base.apk and wondered what it does. You’ll only be able to see these base.apk files if you have root access on your phone, since they’re in protected system folders. This is a file that you’ll find in every app folder. It contains the basic code and resources of the app, such as icons, layouts, strings, etc. The other files in the app folder are split APKs, which contain additional code and resources for specific features, such as languages, architectures, screen densities, etc.

Split APKs are a new format introduced by Google in 2018 to allow developers to reduce the size of their apps and optimize them for different devices. Instead of creating a single “fat” APK with all the libraries and resources in it, developers can now create an app bundle that Google then splits into multiple chunks – hence the term split APKs. Each release then consists of a base APK and one or more split APKs.

For example, a single release may now arrive as 5 files: base.apk + arm64.split.apk + 320dpi.split.apk + en-us.lang.split.apk + es-es.lang.split.apk. Unfortunately, you can’t install all these split APKs by just tapping them on your device – you can only install the base APK, which will then crash due to missing resources. This is where tools like APKMirror Installer come in handy.

How to Install Base.apk Files?

To install base.apk files along with their split APKs, you need a helper app that can handle this format. One such app is APKMirror Installer, which is developed by the same team behind the popular website APKMirror. This app lets you install .apkm, .xapk, and .apks app bundle files as well as regular APK files.

To use this app, you need to download the .apkm file of the app you want to install from APKMirror or other sources. An .apkm file is a compressed file that contains the base APK and all the split APKs of an app release. Once you’ve downloaded the . apkm file, you need to open it with APKMirror Installer. The app will then scan the file and show you the app information, such as name, version, size, etc. You can then tap on the Install button to proceed with the installation. The app will ask you for the necessary permissions and then install the base APK and all the split APKs on your device. You can then launch the app from your app drawer or home screen.

Alternatively, you can also use other tools that can install split APKs, such as SAI (Split APKs Installer) or App Manager. These apps work similarly to APKMirror Installer, but they may have different features and options. You can choose the one that suits your needs and preferences.

How to Backup and Restore Base.apk Files?

If you want to backup and restore your base.apk files and their split APKs, you need a tool that can handle this format. One such tool is Base Apk, which is a simple and easy-to-use app that lets you backup and restore your apps as .apkm files. This app is especially useful if you want to share your apps with others or transfer them to another device.

To use this app, you need to grant it root access and storage permission. The app will then show you a list of all the apps installed on your device. You can select the apps you want to backup and tap on the Backup button. The app will then create .apkm files for each app and save them in a folder called BaseApk on your internal storage. You can then copy these files to your PC or cloud storage for safekeeping.

To restore your apps, you need to copy the .apkm files back to your device and open them with Base Apk. The app will then scan the files and show you the app information. You can then tap on the Restore button to proceed with the installation. The app will ask you for the necessary permissions and then install the base APK and all the split APKs on your device. You can then launch the app from your app drawer or home screen.

Alternatively, you can also use other methods to backup and restore your base.apk files and their split APKs, such as using a custom recovery like TWRP or using a file manager like Solid Explorer. However, these methods may require more technical skills and knowledge, so they are not recommended for beginners or casual users.

FAQs

What is the difference between base.apk and regular APK?

A regular APK is a single file that contains all the code and resources of an Android app. A base.apk is a file that contains only the basic code and resources of an Android app, which is then complemented by split APKs that contain additional code and resources for specific features.

Why do I need to install base.apk along with split APKs?

You need to install base.apk along with split APKs because they are part of the same app release. If you only install base.apk without split APKs, the app will not work properly or even crash due to missing resources.

How do I know if an app has base.apk and split APKs?

You can check if an app has base.apk and split APKs by using a file manager like Solid Explorer or a tool like App Manager. These apps will show you the app folder and the files inside it. If you see a file called base.apk and other files with .split.apk extension, then the app has base.apk and split APKs.

Can I delete base.apk or split APKs from my device?

You should not delete base.apk or split APKs from your device, as they are essential for the app to function properly. If you delete them, the app may not work or even crash. If you want to uninstall an app, you should use the normal uninstall method from your device settings or app manager.

Can I modify base.apk or split APKs on my device?

You should not modify base.apk or split APKs on your device, as they are signed by the developer and verified by Google. If you modify them, the app may not work or even crash. If you want to customize an app, you should use a modded version of the app that is compatible with your device and Android version.
