FirebaseJob Dispatcher：如何使用 RETRY_POLICY_EXPONENTIAL 指定作业中的重试次数

FirebaseJob Dispatcher: How to specify the number of retries in job with RETRY_POLICY_EXPONENTIAL

如何在重试类型为RETRY_POLICY_EXPONENTIAL的作业中指定重试次数，下面是我的代码

    val job: Job =dispatcher.newJobBuilder()
            .setTag("mytesttag")
            .setService(MyJobService::class.java)
            .setRetryStrategy(RetryStrategy.DEFAULT_EXPONENTIAL)
            .build()

知道了，可以使用 FirebaseJobDispatcher instance，像这样 

        var job = dispatcher.newJobBuilder()
                .setTag("mytesttag")
                .setService(MyJobService::class.java)
                .setRetryStrategy(dispatcher.newRetryStrategy(                        
                 RetryStrategy.RETRY_POLICY_EXPONENTIAL,30,300))
                .build()
