The reason I saw this exception on the Internet was that I used Native Lib or JNI or something like that, which is just a messy package related to hardware anyway.
For example, I used an image compression package that involved JNI, and then the above exception occurred when I packaged it.
Solutions:
In the moudle build.gradle file of your app, paste the code in, note the android {} curly braces.

// 解决 native libraries 不支持cpu的体系结构。允许模拟器调试
splits {
    abi {
        enable true
        reset()
        include 'x86', 'armeabi-v7a','x86_64'
        universalApk true
    }
}

This allows you to run directly into the emulator, but when you do this, multiple ApKs will be generated in the package, so comment out the above code when you release and rebuild the project to package. Remember to always rebuild projects!
