Runtime bug and crash app

[abbasnaqdi]

**This is SneakerHelper class :‌ **

package com.okabbas.olympiad.helper

import android.support.v4.app.FragmentActivity
import com.irozon.sneaker.Sneaker
import com.okabbas.olympiad.R
import com.okabbas.olympiad.app.AppApp
import com.okabbas.olympiad.helper.SneakerHelper.SneakerModel.*

class SneakerHelper {
    private var sneaker: Sneaker? = null

    enum class SneakerModel {
        SUCCESSFUL, UNSUCCESSFUL,
        WARNING, ERROR, WAIT
    }

    fun showMessage(activity: FragmentActivity, message: String, model: SneakerModel) {
        Sneaker.with(activity)
                .setTypeface(AppApp.mediumFont)
                .setTitle("result -> $message", R.color.colorWhite)
                .setIcon(getIcon(model), false)
                .setDuration(5000)
                .autoHide(true)
                .setHeight(150)
                .sneak(getColor(model))
    }

    fun showLoading(activity: FragmentActivity, message: String, model: SneakerModel) {
        sneaker = null
        sneaker = Sneaker.with(activity)
                .setTypeface(AppApp.mediumFont)
                .setTitle(message, R.color.colorWhite)
                .setIcon(getIcon(model), false)
                .setDuration(5000)
                .autoHide(false)
                .setHeight(150)

        sneaker?.sneak(getColor(model))
    }

    fun hideLoading() {
        sneaker?.let {
            it.setDuration(0)
            it.autoHide(true)
            it.setHeight(0);
            it.sneak(R.color.colorBlack);
        }
    }

    private fun getIcon(model: SneakerModel): Int {
        return when (model) {
            SUCCESSFUL -> R.mipmap.ico_successful
            UNSUCCESSFUL -> R.mipmap.ico_unsuccessful
            WARNING -> R.mipmap.ico_warnings
            ERROR -> R.mipmap.ico_error
            WAIT -> R.mipmap.ico_wait
        }
    }

    private fun getColor(model: SneakerModel): Int {
        return when (model) {
            SUCCESSFUL -> R.color.colorPrimaryDark
            UNSUCCESSFUL -> R.color.colorOrange
            WARNING -> R.color.colorRed
            ERROR -> R.color.colorHepatic
            WAIT -> R.color.colorBlack
        }
    }
}

i'm call methods hideLoading and showLoading and showMessage in main activity :
In debug mode, there's no problem, but when I release the application, I get the following errors using the fabric service.
