How to exclude ProGuard for external third party dependency in android

Am using a third party dependency. It works well in debug mode and also it works well if i generate signed apk with

 buildTypes {
    release {

        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.release
    }
}

but crash when

 buildTypes {
    release {

        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.release
    }
}

and my log cat is 

09-05 18:56:39.124 4730-4730/? A/art: art/runtime/java_vm_ext.cc:470] JNI DETECTED ERROR IN APPLICATION: fid == null

The easiest way to do it should be using R8, just add android.enableR8=true in your gradle.properties

Just put this line on ProGuard file 

-keep public class android.support.v4.** { *;}

replace android.support.v4 with your external third party Package name
