What are split APKs and why do they matter?
Split APKs are a way of packaging Android apps that allows developers to create multiple APK files that contain different parts of the app, such as code, resources, assets, or native libraries. The Android platform can treat these split APKs as a single app and install them together on a device.
none of the 1 split apks are compatible with the current device with abis arm64-v8a
Split APKs have several advantages for Android app development and distribution, such as:
Reducing the size of the app download and installation by delivering only the necessary files for each device configuration.
Supporting multiple device features and architectures without creating separate app versions.
Enabling dynamic delivery of app modules or features on demand.
Improving app performance and security by isolating code and resources.
How to create and install split APKs on Android devices?
There are different tools and methods for generating and deploying split APKs on Android devices, depending on your development environment and preferences. Some of the most common ones are:
Android Studio: The official IDE for Android development supports creating split APKs using the to configure your build for multiple APKs based on screen densities or ABIs.
Gradle: The build automation tool for Android projects allows you to create split APKs using in your module-level build.gradle file. You can specify which screen densities or ABIs you want to support or exclude, and Gradle will generate separate APK files for each combination.
SAI: The is an Android app that lets you install split APKs (such as ones distributed as Android App Bundle) on your device. It has both rooted and rootless installation methods.
What are ABIs and how do they affect split APKs compatibility?
Application Binary Interfaces (ABIs) are specifications that define how machine code interacts with the Android system at run time. They include information such as:
The CPU architecture and instruction set (such as ARM, x86, or MIPS).
The system libraries and their versions (such as libc, libm, or libstdc++).
The calling conventions and data types (such as how to pass arguments and return values).
ABIs affect split APKs compatibility because they determine which native libraries can run on a device. If an app has native code, it needs to provide a separate library for each ABI it supports. For example, an app that supports both armeabi-v7a and arm64-v8a ABIs will have two libraries: lib/armeabi-v7a/libapp.so and lib/arm64-v8a/libapp.so.

What are the supported ABIs for Android devices?
Android supports the following ABIs for devices:
ABIDescription
armeabi-v7aARMv7 32-bit instruction set with hardware floating-point support.
arm64-v8aARMv8 64-bit instruction set with hardware floating-point support.
x86x86 32-bit instruction set with MMX and SSE extensions.
x86_64x86 64-bit instruction set with MMX and SSE extensions.
mipsMIPS32 32-bit instruction set.
mips64MIPS64 64-bit instruction set.
Note that some ABIs are deprecated or removed in newer Android versions, such as armeabi, mips, and mips64. You can check the for more details on the supported ABIs and their compatibility.
How to check the ABI of your device and app?
To find out the ABI of your device, you can use one of the following methods:
adb: The Android Debug Bridge is a command-line tool that lets you communicate with your device. You can use the command adb shell getprop ro.product.cpu.abi to get the primary ABI of your device, or adb shell getprop ro.product.cpu.abilist to get a list of all supported ABIs.
Third-party app: There are several apps that can show you the ABI of your device, such as . You can download them from Google Play or other sources and install them on your device.
To check the ABI of your app, you can use one of the following methods:
apktool: This is a tool that can decode and rebuild APK files. You can use the command apktool d app.apk to extract the contents of your app APK file, and then look for the lib folder to see which ABIs are supported by your app.
aapt: This is a tool that can display information about APK files. You can use the command aapt dump badging app.apk grep native-code to see which ABIs are supported by your app.
What causes the error "none of the 1 split apks are compatible with the current device with abis arm64-v8a"?
This error message means that none of the split APKs that you are trying to install on your device match the ABI of your device, which is arm64-v8a. This could happen for several reasons, such as:
Your app does not support arm64-v8a ABI, but only other ABIs such as armeabi-v7a or x86. This could be because you did not include the arm64-v8a library in your app, or because you excluded it from your build configuration.
Your app supports arm64-v8a ABI, but the split APK file that contains it is corrupted or missing. This could be because you did not download or transfer the file correctly, or because it was deleted or modified by mistake.
Your app supports arm64-v8a ABI, but it also requires some features that are not available on your device, such as OpenGL ES 3.0 or higher. This could be because you did not specify the required features in your app manifest, or because your device does not support them.
How to fix this error and install split APKs successfully?
To resolve this error and install split APKs on your device, you can try one of the following suggestions:
Use a different installer: If you are using SAI to install split APKs, you can try using another installer app that supports split APKs, such as to install your app if it is published there.
Change the ABI settings: If you are using Android Studio or Gradle to create split APKs, you can change the ABI settings in your build configuration to include or exclude arm64-v8a ABI. You can also use the --split-per-abi option in the bundletool command to generate separate APK files for each ABI.
Rebuild the APK files: If you suspect that your split APK files are corrupted or missing, you can try rebuilding them using Android Studio, Gradle, or apktool. You can also use a tool like to verify and sign your APK files.
Conclusion
Split APKs are a useful feature for Android app development and distribution, as they allow developers to create multiple APK files that contain different parts of the app, such as code, resources, assets, or native libraries. This can reduce the size of the app download and installation, support multiple device features and architectures, enable dynamic delivery of app modules or features, and improve app performance and security.
However, split APKs also introduce some challenges and issues for compatibility, especially when it comes to ABIs. ABIs are specifications that define how machine code interacts with the Android system at run time. They include information such as the CPU architecture, the system libraries, and the calling conventions. If an app has native code, it needs to provide a separate library for each ABI it supports.
Sometimes, you may encounter an error message like "none of the 1 split apks are compatible with the current device with abis arm64-v8a" when trying to install split APKs on your device. This means that none of the split APKs match the ABI of your device, which is arm64-v8a. This could happen for various reasons, such as mismatched ABIs, corrupted APK files, or unsupported features.
To fix this error and install split APKs successfully, you can try using a different installer app, changing the ABI settings in your build configuration, or rebuilding the APK files. You can also check the ABI of your device and app using adb, apktool, or a third-party app.
FAQs
What is the difference between arm64-v8a and armeabi-v7a?
Arm64-v8a and armeabi-v7a are two different ABIs for Android devices. Arm64-v8a is based on the ARMv8 64-bit instruction set with hardware floating-point support. Armeabi-v7a is based on the ARMv7 32-bit instruction set with hardware floating-point support. Arm64-v8a devices can run both arm64-v8a and armeabi-v7a libraries, but armeabi-v7a devices can only run armeabi-v7a libraries.
How do I know which ABIs my app supports?
You can check which ABIs your app supports by using apktool or aapt. Apktool can decode and rebuild APK files, and you can look for the lib folder to see which ABIs are supported by your app. Aapt can display information about APK files, and you can use the command aapt dump badging app.apk grep native-code to see which ABIs are supported by your app.
How do I change the ABI settings in Android Studio?
You can change the ABI settings in Android Studio by using the Android App Bundle format or Gradle. The Android App Bundle format is a publishing format that Google Play uses to generate optimized APKs for each device configuration. You can use the android.bundle.abi.enableSplit property in your module-level build.gradle file to enable or disable split APKs by ABI. Gradle is the build automation tool for Android projects, and you can use the splits block in your module-level build.gradle file to configure your build for multiple APKs based on screen densities or ABIs.
