========================================================================= In my app build.gradle file comment:

    compile files('libs/miio.jar')
    ...
}

splits {
    abi {

        reset()
        include 'armeabi' ,'armeabi-v7a','arm64-v8a', 'x86'
        universalApk false

sourceSets {
    main {
        jni.srcDirs = []
        jniLibs.srcDirs = ['libs']
    }
}

buildTypes {
    release {
        minifyEnabled true
        zipAlignEnabled true
        shrinkResources false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.release
}

========================================================================= In root libs directory files:

--libs
    --arm64-v8a//folder name
        --libmiio.so//file
    --miio.jar//file

========================================================================= In proguard-rules.pro:

 -dontwarn com.xiaomi.**
 -keep class com.xiaomi.**{*;}
 -keep interface com.xiaomi.** { *;}

it looks not related with proguard, what is your final apk structure? Double check that your apk really includes the needed `.so` for your device architecture. — shizhen, Aug 27 '18 at 09:24

I searched on the net these days and finally found the solution! If you are using Android studio, just edit the gradle.properties in the root folder and add android.useDeprecatedNdk=true. Then edit the build.gradle file in your app's folder, set abiFilters as below:

android {
....
defaultConfig {
    ....
    ndk {
        abiFilters "armeabi", "armeabi-v7a", "x86", "mips"
    }
}

}

The root cause is found, because of my app build.gradle configuration:splits { abi { enable true reset() include 'armeabi' ,'armeabi-v7a','arm64-v8a' universalApk false } } – tingting li Aug 28 '18 at 06:14

The root cause is found, because of my app build.gradle configuration:

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

But in my libs folder, I don't config armeabi folder
