Hello! Where do you initialize the sdk instance with UnifiedSDK.getInstance(ClientInfo)?

[mwaked]

@timoshenkoav in the Application class

class MainApplication : Application() {

    private var unifiedSDK: UnifiedSDK? = null

    companion object {
        const val CHANNEL_ID = "vpn"

        var selectedCountry = UnifiedSDK.COUNTRY_OPTIMAL

        private var mInstance:  MainApplication? = null
        @Synchronized
        fun getInstance():  MainApplication {
            if (mInstance == null) mInstance = MainApplication()
            return mInstance!!
        }
    }

    private val prefs: SharedPreferences
        get() = getSharedPreferences(BuildConfig.SHARED_PREFS, Context.MODE_PRIVATE)

    override fun onCreate() {
        super.onCreate()

        mInstance = this

        initHydraSdk()
}

 private fun initHydraSdk() {
        createNotificationChannel()
        val clientInfo = ClientInfo.newBuilder()
                .baseUrl(prefs.getString(BuildConfig.STORED_HOST_URL_KEY, BuildConfig.BASE_HOST)!!)
                .carrierId(prefs.getString(BuildConfig.STORED_CARRIER_ID_KEY, BuildConfig.BASE_CARRIER_ID)!!)
                .build()
        val transportConfigList: MutableList<TransportConfig> = ArrayList()
        transportConfigList.add(HydraTransportConfig.create())
        transportConfigList.add(OpenVpnTransportConfig.tcp())
        transportConfigList.add(OpenVpnTransportConfig.udp())
        UnifiedSDK.update(transportConfigList, CompletableCallback.EMPTY)
        val config = UnifiedSDKConfig.newBuilder().idfaEnabled(false).build()
        unifiedSDK = UnifiedSDK.getInstance(clientInfo, config)
        val notificationConfig = NotificationConfig.newBuilder()
                .title(resources.getString(R.string.app_name))
                .channelId(CHANNEL_ID)
                .build()
        UnifiedSDK.update(notificationConfig)
        UnifiedSDK.setLoggingLevel(Log.VERBOSE)
    }

    fun setNewHostAndCarrier(hostUrl: String?, carrierId: String?) {
        if (TextUtils.isEmpty(hostUrl)) {
            prefs.edit().remove(BuildConfig.STORED_HOST_URL_KEY).apply()
        } else {
            prefs.edit().putString(BuildConfig.STORED_HOST_URL_KEY, hostUrl).apply()
        }
        if (TextUtils.isEmpty(carrierId)) {
            prefs.edit().remove(BuildConfig.STORED_CARRIER_ID_KEY).apply()
        } else {
            prefs.edit().putString(BuildConfig.STORED_CARRIER_ID_KEY, carrierId).apply()
        }
        initHydraSdk()
    }
}

ok, everything seems fine. i will investigate the issue, for now you can try to switch and use UnifiedSDK instance you have in your application. instead of using UnifiedSDK.getInstance()

@timoshenkoav Ok, Thank you

[AbdulBari68]

@timoshenkoav can you please explain more about (UnifiedSDK instance you have in application. ?? )
