JobIntentService中onHandleWork内部的Secondry构造函数数据为空

Question

我不知道为什么onHandleWork内部的数据为null，这是我的努力：

class OfferJobIntentService :JobIntentService {
            var oppoPayRepository:OppoPayRepository?=null
            var preferenceProvider: PreferenceProvider?=null

            constructor()  // secondary constructor

            constructor(oppoPayRepository:OppoPayRepository,preferenceProvider: PreferenceProvider):this(){  // secondary constructor
                this.oppoPayRepository = oppoPayRepository
                this.preferenceProvider=preferenceProvider
                Log.e("msg1--","oppoPayRepository1"+oppoPayRepository+"----"+preferenceProvider)

            }

            override fun onHandleWork(intent: Intent) {
                if(oppoPayRepository!=null){
                    Log.e("msg2--","oppoPayRepository2--"+oppoPayRepository)
                }else{
                    Log.e("msg3--","null")
                }
