Can't install app for Android Example

Hi,

I want to perform federated learning with Android Clients, and I tired to run through the Flower Android Example in this repo. However, I failed to install the apk file on all 3 Android mobiles. It says that [INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113] Is there anything I can do to solve this problem?

Sorry for the late reply… I was busy for the past few days. And thank you for your reply!!!

I don’t know how to run the command adb shell getprop ro.product.cpu.abilist on my phone, so I downloaded an app that tells the command set (not sure what the actual English word for this is) the mobile uses.

2 of the above mobiles use arm64-v8a. (I didn’t test the third one due to memory shortage) Therefore, I appended the following configuration to build.gradle under the app folder like you said.

splits {
    abi {
        enable true
        reset()
        include 'x86', 'armeabi-v7a', 'x86_64', 'arm64-v8a'
        universalApk true
    }
}

( I found out later that I could simply include ‘arm64-v8a’ to build the desired APK. From the above configuration, it will build different APKs for different “command sets” if I understand it correctly.)

The APK built with ‘arm64-v8a’ can be installed successfully on both mobiles. Both of them seem to be running, even with Android version = 8.1.0. I will then take a closer look at what the app is doing exactly and how.

Thank you for all your assistance!! It is really a huge help for me!!! Thank you again and Merry Christmas~~
