Guide to Installing Split APKs Using SAI

In the evolving landscape of Android app distribution, developers are increasingly utilizing the Android App Bundle format, which results in split APKs. These are multiple APK files that, together, make up a single application. Installing such apps requires specialized tools, and one of the most reliable among them is the Split APKs Installer (SAI). This guide will walk you through the process of installing split APKs using SAI, ensuring a seamless experience.

Understanding Split APKs

Split APKs are a set of APK files that, collectively, constitute a complete Android application. Unlike traditional single APK files, split APKs allow for more efficient app delivery by including only the necessary components for a specific device configuration. This modular approach reduces app size and optimizes performance.

Introducing SAI (Split APKs Installer)

SAI is a third-party Android application designed to install split APKs. It provides a user-friendly interface and supports various installation methods, including rootless and rooted installations. SAI is particularly useful for installing apps that are distributed outside the Google Play Store in the split APK format.

Preparing for Installation

Before proceeding with the installation of split APKs using SAI, ensure the following prerequisites are met:

• Device Compatibility: Your Android device should be running Android 5.0 (Lollipop) or higher.
• Enable Unknown Sources: Allow installations from unknown sources by navigating to Settings > Security > Install unknown apps, then select the app (e.g., your browser or file manager) and enable “Allow from this source.”
• Download SAI: Obtain the latest version of SAI from a trusted source of PlayStore.

Step-by-Step Installation Guide

1. Install SAI:

• Open the downloaded SAI APK file.
• Tap “Install” and wait for the installation to complete.

2. Launch SAI:

• Open the SAI app from your app drawer.
• Grant any necessary permissions requested by the app.

3. Select Installation Method:

• In SAI, tap on the “Install APKs” button.
• Choose the file picker method (internal or system) to locate your split APK files.

4. Locate and Select Split APK Files:

• Navigate to the folder containing the split APK files (.apks or multiple .apk files).
• Select the required files for installation.

5. Initiate Installation:

• After selecting the files, SAI will prompt you to confirm the installation.
• Tap “Install” to begin the process.

6. Complete Installation:

• Wait for the installation to finish.
• Once completed, you can open the newly installed app from your app drawer.

Troubleshooting Common Issues with SAI

While SAI is a powerful tool for installing Split APKs, users may encounter certain challenges. Here’s how to address some common issues:

1. “INSTALL_FAILED_ABORTED: User rejected permissions” Error

Cause: This error often arises on devices running Android 12 or newer, particularly on custom ROMs or specific manufacturer skins like ColorOS (found on Oppo and OnePlus devices). It indicates that the system’s package installer has rejected the installation due to permission issues.

Solution:

Use the ‘Cross Profile Test’ App:

• Install the ‘Cross Profile Test’ app from a trusted source.
• Do not open the app after installation.
• Reboot your device.
• Proceed to install your Split APKs using SAI.
• After successful installation, uninstall the ‘Cross Profile Test’ app and reboot your device again.

This workaround has been reported to resolve installation issues on certain devices .

2. SAI Not Supporting .apks Files

Cause: SAI may not recognize or support certain .apks files, especially if they are encrypted or not properly formatted.

Solution:

• Ensure File Integrity: Verify that the .apks file is not corrupted and is obtained from a reliable source.
• Use Alternative Tools: Consider using other tools like APKMirror Installer or APKTool M, which may offer better compatibility with certain .apks files.

3. Installation Fails Without Root Access

Cause: Some installations may fail if the device lacks root access, especially when dealing with certain system-level apps or configurations.

Solution:

• Enable Root Access: If you’re comfortable with rooting your device, enabling root access can resolve these issues.
• Use ADB for Installation: Alternatively, use Android Debug Bridge (ADB) to install Split APKs without root:
