android - 如果我需要使用 jobInfo 执行重复任务，我该如何设置 jobFinished()？

Question

我希望用JobScheduler执行一个重复的任务。

我无法完全理解官方文档中有趣的jobFinished()。

如果希望任务可以重复执行，jobFinished(parameters, false) 和jobFinished(parameters, true) 哪个代码是正确的？

顺便说一句，我已经为 JobScheduler 设置了 setPeriodic(interval)

代码

private fun startScheduleRestore(mContext:Context){
   logError("Start Server")

   val interval=10 *1000L

    val mJobScheduler = mContext.getSystemService(Context.JOB_SCHEDULER_SERVICE) as JobScheduler

    val jobInfo = JobInfo.Builder(mContext.getInteger(R.integer.JobID), ComponentName(mContext, RestoreService::class.java))
                        .setPeriodic(interval)
                        .setPersisted(true)
                        .build()

    mJobScheduler.schedule(jobInfo)
}



class RestoreService : JobService() {
    override fun onCreate() {
        logError("OnCreate")
        super.onCreate()
    }

    override fun onDestroy() {
        logError("OnDestory")
        super.onDestroy()
    }

    override fun onStartJob(params: JobParameters): Boolean {
        Thread(Runnable { completeRestore(params) }).start()
        return true
    }

    override fun onStopJob(params: JobParameters): Boolean {
        logError("OnStop")
        return false
    }


    fun completeRestore(parameters: JobParameters) {
        logError("Starting")
        jobFinished(parameters, false)
    }

}

基于documentation :

You can request that the job be scheduled again by passing true as the wantsReschedule parameter. This will apply back-off policy for the job; this policy can be adjusted through the setBackoffCriteria(long, int) method when the job is originally scheduled. The job's initial requirements are preserved when jobs are rescheduled, regardless of backed-off policy.

jobFinished(parameters, true) 将重新安排您的工作。

如果你想定期执行某事，那么使用 setPeriodic在你的 JobInfo.Builder
