    	}
	}
}

dependencies {
  implementation(name: 'ttc_pay_xxx', ext: 'aar')

    override fun error(errorBean: ErrorBean) {

         //Utils.toast(activity, ttcOrderId)
    }

    override fun error(errorBean: ErrorBean) {
        //Utils.toast(activity, errorBean.getErrorMsg())
    }

    override fun payFinish(ttcOrderId: String, txHash: String, orderState: Int) {
    }
})
