And this is part of my current build.gradle:

android {
    compileSdkVersion 24
    buildToolsVersion '25.0.2'
    defaultConfig {
        ...
        minSdkVersion 16
        targetSdkVersion 24
        ...
        multiDexEnabled true
        vectorDrawables.useSupportLibrary = true
    }
    buildTypes {
       ...
    }
    lintOptions {
        abortOnError false
    }
    productFlavors {
    }
    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
    }
    dexOptions {
        javaMaxHeapSize "2g"
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile('com.crashlytics.sdk.android:crashlytics:2.6.7@aar') { transitive = true }
    ...
    compile group: 'com.pubnub', name: 'pubnub-gson', version: '4.6.0'
    ...
    compile 'com.snappydb:snappydb-lib:0.5.2'
    compile 'com.esotericsoftware.kryo:kryo:2.24.0'
}

apply plugin: 'com.google.gms.google-services'

And this only happened in Android 4.4 and PubNub SDK is 4.X. If I use PubNub 3.X with the same build.gradle, then it works well no matter Android version is 4.4 or 5/6/7. I don't think this is due to SnappyDB. But probably anyone knows other way which could avoid such runtime error? Thanks.

Possibly a Kryo version mismatch...

In my case it was version conflict with another copy included as a dependency for SnappyDB
