Here is Kotlin version.
Thanks you :)

         fun unSafeOkHttpClient() :OkHttpClient.Builder {
            val okHttpClient = OkHttpClient.Builder()
            try {
                // Create a trust manager that does not validate certificate chains
                val trustAllCerts:  Array = arrayOf(object : X509TrustManager {
                    override fun checkClientTrusted(chain: Array?, authType: String?){}
                    override fun checkServerTrusted(chain: Array?, authType: String?) {}
                    override fun getAcceptedIssuers(): Array  = arrayOf()
                })

                // Install the all-trusting trust manager
                val  sslContext = SSLContext.getInstance("SSL")
                sslContext.init(null, trustAllCerts, SecureRandom())

                // Create an ssl socket factory with our all-trusting manager
                val sslSocketFactory = sslContext.socketFactory
                if (trustAllCerts.isNotEmpty() &&  trustAllCerts.first() is X509TrustManager) {
                    okHttpClient.sslSocketFactory(sslSocketFactory, trustAllCerts.first() as X509TrustManager)
                    okHttpClient.hostnameVerifier { _, _ -> true }
                }

                return okHttpClient
            } catch (e: Exception) {
                return okHttpClient
            }
        }
