With the growing diversity of Android devices, developers have increasingly turned to APK bundles (also known as split APKs) to ensure that their apps can efficiently cater to a wide range of device specifications. These bundles provide a more efficient way of packaging and distributing Android apps, especially for those with different screen sizes, architectures, or language preferences. However, installing APK bundles can be tricky for users who are accustomed to the traditional single APK format.
In this article, we’ll explain what APK bundles are, why they’re used, and how to install them on your Android device.
1. What is an APK Bundle (Split APK)?
An APK Bundle (or App Bundle) is a publishing format introduced by Google that helps developers create smaller, more efficient apps. Unlike traditional APKs, which contain all of the app’s resources and code in a single file, an APK Bundle contains multiple APKs that correspond to different configurations of the app. These configurations can include different device screen sizes, CPU architectures, language options, and more.
In the APK Bundle format, the app is split into multiple parts, including:
- Base APK: This is the core APK containing essential resources and code common to all device configurations.
- Configuration APKs: These APKs are used to deliver device-specific resources like screen density, CPU architecture, and languages. For example, there could be separate APKs for x86 or ARM architecture, or different screen sizes (small, medium, large).
When you download an app through the Google Play Store, the Play Store automatically selects and installs the relevant APKs for your device. However, if you’re sideloading the APK bundle (downloading the APKs outside of the Play Store), you’ll need to manually install each APK part, which can get complicated.
2. Why Do Developers Use APK Bundles?
The main reason developers prefer APK bundles is to optimize app size and performance. Here’s how APK bundles benefit both developers and users:
- Reduced App Size: APK Bundles ensure that users only download the parts of the app that are relevant to their specific device, making the app smaller and faster to install. This helps save bandwidth and storage space on devices.
- Improved Efficiency: By creating separate APKs for different device configurations, developers avoid the need to ship one large APK that includes resources for all devices. This results in more efficient downloads and installations.
- Better Device Compatibility: APK bundles help ensure that apps run smoothly across different device types, as they allow developers to target specific device configurations rather than using a universal APK that may include unnecessary resources for certain devices.
3. How to Install APK Bundles (Split APKs)
Installing APK Bundles manually requires more steps than installing a standard APK. While the Google Play Store does this automatically, when sideloading APK bundles, you’ll need to make sure you install the right combination of APKs. Below are the general steps for installing APK Bundles on Android.
Step 1: Download the APK Bundle
To install an APK bundle, you’ll need to first download the APK bundle files. These files often come with the extension .apks or .xapk, which is a format that packages all the APKs (base APK and configuration APKs) into a single archive. Websites like APKPure or APKMirror may offer APK bundles for download.
Step 2: Use a Split APK Installer
To properly install APK bundles, you’ll need a special app that can handle split APKs, as Android doesn’t natively support installing bundles. Here are two popular tools you can use:
- Split APKs Installer (SAI): SAI is a popular third-party app that makes it easy to install split APKs. The app allows you to select the APK files and install them on your device with a few simple steps.Steps:
- Download and install Split APKs Installer (SAI) from the Google Play Store or from a trusted third-party source.
- Open SAI and select “Install APKs”.
- Browse and select the APK bundle file (it may be in .apks or .xapk format).
- SAI will extract the APKs and install them on your device automatically.
- Once installed, you should be able to open the app.
- App Bundle Installer: Another app designed to handle APK bundles is the App Bundle Installer, available on the Play Store or as a direct download from certain APK sites. This app also helps you install APKs that are in the .xapk format.Steps:
- Download and install App Bundle Installer from a trusted source.
- Open the app, browse to the location of the APK bundle file, and select it.
- The installer will automatically handle the installation process by extracting the required APKs and setting up the app.
Step 3: Enable “Install from Unknown Sources”
Since you’re installing apps from sources outside the Google Play Store, you need to enable the option to install from unknown sources. To do this:
- Go to Settings on your Android device.
- Tap Security or Privacy (depending on your Android version).
- Enable Install from Unknown Sources for the specific app you’re using to install the APK bundle (e.g., Split APKs Installer).
For devices running Android 8.0 (Oreo) or later, this option is app-specific, so you’ll need to enable it for the file manager or browser you’re using to open the APK bundle.
Step 4: Install the APK Bundle
Once the APK bundle is ready and the installation app is set up, you can proceed with the installation. If you are using Split APKs Installer (SAI), follow these steps:
- Launch SAI and tap Install APKs.
- Browse to the location of your downloaded APK bundle (.apks or .xapk).
- Select the file and SAI will automatically extract the individual APK files and install them.
- Once the process is complete, you should see the app in your app drawer.
For App Bundle Installer, the process is very similar: open the app, select the APK file, and let it handle the installation.
Step 5: Verify the Installation
Once installed, go to your App Drawer to check if the app has been installed successfully. You can now open the app and start using it.
4. Troubleshooting APK Bundle Installation Issues
While installing APK bundles is straightforward with the right tools, sometimes issues may arise. Here are a few common troubleshooting tips:
- Installation Failed: If the installation fails, ensure that all parts of the APK bundle are properly downloaded. You may have a corrupt or incomplete APK file. Try downloading the bundle again from a trusted source.
- Compatibility Issues: Make sure the APK bundle is compatible with your device’s architecture and Android version. If you’re not sure about your device’s specifications, try searching for a version of the app tailored for your device.
- Permissions Issues: If you’re unable to install the APK, check if the app you’re using to install the APK bundle has the necessary permissions enabled to install apps from unknown sources.
5. Conclusion
APK bundles (split APKs) offer a more efficient way of distributing Android apps, especially when considering device-specific configurations. While installing APK bundles is a bit more complicated than installing a single APK, it can be done easily with the help of third-party tools like Split APKs Installer and App Bundle Installer.
By following the steps outlined in this guide, you can sideload and install APK bundles on your Android device. Just ensure that you download your APK bundles from trusted sources, enable the necessary permissions, and use the right installer to handle the installation process. With a little effort, you can enjoy the benefits of APK bundles without much hassle.
