How to use proguard with Hyperledger Iroha?

Question

I I have problem on proguard with Hyperledger Iroha on android.

buildTypes {
    release {
        debuggable false
        minifyEnabled true
        shrinkResources false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
    debug{
        debuggable true
        minifyEnabled true
        shrinkResources false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}

when I did: minifyEnabled true after building release apk: app-release.apk, the app crashed.
when I did: minifyEnabled false after building release apk: app-release.apk, the app is okay.
Result error is:
